1) The first case of Lumpy Skin Disease (LSD) in Albania was identified in June 2016. From 2016-2017, over 3,500 outbreaks were reported across Albania with morbidity of 42% and mortality of 12%.
2) Surveillance efforts included laboratory testing of over 2,000 samples confirming 881 positive cases. Risk factors for spread included proximity to infected farms (under 5km), livestock movements over longer distances, and seasonal variations correlated with temperature and vector abundance.
3) Control efforts included an emergency vaccination program using live attenuated vaccine beginning in July 2016. Over 500,000 vaccine doses were administered. Modeling estimated vaccine effectiveness was 76.5-62.5% at reducing
LSD symposium - J. Chan - Lumpy skin disease in Hong KongEuFMD
Dr. Jason Chan presented on the outbreak of Lumpy Skin Disease (LSD) in feral cattle populations in Hong Kong from 2020-2021. The key points were:
1) The initial outbreak was reported in October 2020 across multiple country parks. Disease investigation found that 72% of cattle in one herd showed skin lesions and 84% were seropositive.
2) By March 2021, no new clinical cases were reported. Surveillance since found 14 juveniles seronegative, suggesting LSD may have disappeared due to lack of susceptible newborn cattle.
3) Continued clinical and serological surveillance is important since Hong Kong has a small teaching farm. No urgency exists currently to declare freedom

The Socio-Economics and Burden Impact of Rift Valley Fever in Garissa, KenyaNanyingi Mark
Rift Valley fever (RVF) is a viral, vector borne zoonosis that has significant threat to livestock health and production and public health in Africa. Recent outbreaks have led to high livestock mortalities and human morbidity and socio economic impacts in Garissa. To assess the level of knowledge of pastoralists to causation and transmission risk factors and describe their attitude and practices in response to RVF outbreaks and management in the context of climate change shocks. To estimate the livelihood losses and burden impacts in Garissa. A population based cross sectional household survey was conducted in March 2012 and March 2013 in four hotspots. A multistage purposive sampling was used to identify 250 participants who included pastoralists, veterinary and medical personnel and livestock traders. KAP evaluation was by questionnaires in depth key informant interviews and focus group discussions. Participatory rural appraisal tools were used to assess the economic significance of the RVF outbreaks, risk factors and management costs. 185 respondents (74%) had good knowledge of RVF (symptoms scored >50%) and risk factor analysis indicated > 150 (60%) understood the consumption of meat of dead or infected animal, milk, touching aborted foetuses caused disease. Estimated lost revenue due to closure of livestock markets and bans was over Ksh.3 billion. Intervention costs and burden of the outbreaks is discussed. There is good knowledge and attitude on RVF risk, transmission and control. It re-emergence is associated with negative impacts on livelihoods and economic endpoints in Garissa.

Cattle Ticks and Risk Factors Related to Tick Infestation of Livestock in Per...Agriculture Journal IJOEAR
Tick-borne diseases are a global public health problem, particularly in sub-Saharan Africa, where most of the disease is caused by malaria and many other diseases of viral, parasitic or bacterial origin. This study aimed to identify the bovine tick's species in cattle farms and to determine possible risk factors related to tick infestation in Abidjan district and Azaguié commune. Thus, in July 2019, thirteen (13) herds distributed in these localities were visited for tick sampling and to conduct epidemiological investigations. At each visit, ticks were harvested from 15 cattle per herd. All the farms visited were infested with ticks. 96.92% of sampled animals had ticks. A total of 1796 ticks were collected of which 89.42% (1606) were adults, 10.41% (187) were pupae and 0.17% (3) was larvae. Two species of ticks have been identified, Amblyomma variegatum with 25% of the population and Rhipicephalus (Boophilus) microplus with 75%. 96% of the cattle were infested by ticks of the species R. (B.) microplus and 56% of the cattle were infested by ticks of the species A. variegatum. The co-infestation of cattle by the two identified species was 53%. The distribution of the sexes showed that in the species A. variegatum, males were more numerous (13.44% for males and 8.76% for females). However in the species R. (B.) microplus, females were more numerous (5.08% for males and 62.3% for females).The analysis of risk factors associated with tick infestation in cattle has shown that factors such as Undefined parks, Type of pasture, Training in the use of acaricides and Presence of wild animals contribute to major ectoparasite infestations in cattle. Tick samples collected from peri-urban farms in the district of Abidjan and the locality of Azaguié as part of this study, indicate that the relatively recent introduction of the species Rhipicephalus (Boophilus) microplus presents a threat to animal and human health.

A five-year retrospective and one-year prospective studies of gastrointestinal (GIT) helminths was carried out in humans and dogs in Makurdi, Nigeria. Data from 534 individuals presented at the Federal Medical Centre (FMC) and 103 faecal samples from dogs at the Veterinary Teaching Hospital (VTH), University of Agriculture, Makurdi from 2007 to 2014 were used. The overall prevalence of zoonotic GIT helminths in humans was 76.21% (407/534) and 56.31% (58/103) in dogs. The differences in the prevalences in humans based on sex,ethnicity and age were not statistically significant (χ2 , P< 0.05). However, the test of individual factor (coefficient) on GIT helminthes in humans showed that hookworms prevalence was dependent on age (P = 0.001), Ascaris lumbricoides was dependent on ethnicity and age (P = 0.000 and 0.005), Taenia spp. prevalence was dependent on age and sex (P = 0.007 and 0.005), and Strongyloides stercoralis prevalence was dependent on age (P = 0.04). The prevalence in dogs depended on age and breed (χ2 ,P < 0.05) but not on sex (χ2 ,P > 0.05). Hookworms, Taenia spp and Trichuris vulpisoccurred in humans and dogs. Hookworms were the most common helminth of both humans and dogs. Individual factor (coefficient) on the effect of risk factors on specific helminths is essential in understanding the epidemiology of each helminth.

Foot-and-mouth disease risk mapping in Georgia EuFMD
This document summarizes a study that mapped the risk of foot-and-mouth disease (FMD) in Georgia. Data was collected in 2020 on seasonal animal migration patterns between 12 districts, live animal exports from 7 districts, imports from 24 districts, 26 live animal markets, and 5 veterinary inspection points. Analysis showed high levels of animal movement, particularly the seasonal migration of over 721,000 small ruminants from eastern Georgia. This mobility increases the risk of FMD introduction and spread. The risk mapping confirms that eastern Georgia has higher risks and should remain a focus of control efforts. Future risk maps of neighboring countries will allow for better disease prediction and targeting of measures.

The Rhipicephalus microplus tick is a major economic and veterinary concern on livestock production in tropical regions of the world. In Côte d’Ivoire, this invasive and proliferating tick has occupied almost the entire territory. To assess the prevalence of tick-borne haemoparasites in cattle following this invasion, a parasitological study was carried out in 179 farms in 54 departments. Blood and tick samples were collected from 895 cattle over one year of age, with 5 individuals per farm. Ten tick species were identified, of which Rhipicephalus microplus the most found. Microscopic analysis of blood smears identified 3 tick-borne haemoparasites: Anaplasma marginale, Anaplasma centrale and Babesia bovis, with prevalences between 4% and 24% according to departments. Only the Southern, Central, and Northern zones were infested with tick-borne haemoparasites of cattle. The highest prevalence of Babesia bovis (8%) was found in the Southern zone. Agboville’s department was the most infested by A. marginale (24%) and B. bovis (20%). Parasitological analyses revealed a low prevalence of tick-borne haemoparasites in Côte d’Ivoire. A molecular study should be conducted to confirm these results.

2) The program successfully reduced rabies incidence between 1983-1988 and 1993-2010. However, cases have increased again from 2012-2015, calling for improvements to the program, including increasing dog vaccination coverage and public education.
3) The Pasteur Institute Rabies Laboratory plays a key role in epidemiological surveillance and evaluation of control efforts in Tunisia. It
Agriculture, Health and Food-Borne and Zoonotic Diseases - Dr Joachim Otte, FAOLIDC
The document discusses the relationship between agriculture, health, and emerging zoonotic diseases. It notes that intensification of livestock production, human encroachment on wildlife habitats, and increased demand for meat have contributed to increased risk of disease transmission at the wildlife-livestock-human interface. The document also examines trends in disease emergence, including the large number of potential zoonotic viruses yet to be discovered. It argues that an integrated approach across disciplines is needed to address challenges at the agriculture-health nexus.
This document presents a livestock mortality model and vulnerability index (MDVI) developed for Mongolia. The model uses data on winter temperature/snowfall anomalies, forage biomass anomalies, pasture use anomalies, and livestock mortality/productivity scores from 1998-2014. It explains almost two-thirds of historical livestock mortality.
The MDVI was created using the last three variables to produce vulnerability-based early warnings. Four vulnerability classes were established, correlated with average mortality rates and likelihood of severe mortality. The index uses data from the prior year to predict vulnerability and support disaster risk reduction. The model contributes to efforts to better understand and forecast dzud risk in Mongolia.

The random forest algorithm was used to analyze data from a bovine viral diarrhea virus (BVDV) prevalence study and identify important predictors of BVDV occurrence. A random forest model was trained on data from 388 dairy farms tested for BVDV. Variable importance analysis identified the most important predictors of BVDV as who inseminates the animals on the farm, the number of neighboring farms with cattle, and whether rectal palpation was routinely performed. The random forest model had an error rate of 32.03% for correctly predicting negative farms and 36.78% for positive farms, with an area under the ROC curve of 0.702.

One Health Epidemic Risk Management in Kazakhstan With Open-source Eidss Al...Global Risk Forum GRFDavos
Kazakhstan faces risks from diseases such as plague, tularemia, and anthrax. The authors propose developing a Regional Sanitary-Epidemiological Passport (RSEP) to assess epidemic risks in each district of Kazakhstan. The RSEP would use data on infectious disease rates, population counts, and other factors to generate forecasts of risk levels for diseases over 1-2 years. An open-source Electronic Integrated Disease Surveillance System (EIDSS) would collect case data to feed into the RSEP models. The authors plan to develop and validate the RSEP approach over several stages focused on different regions of Kazakhstan.
VADEMOS VAccine Demand Estimation Model for FMD.pdfEuFMD
VADEMOS is a decision support tool created by the European Commission for the Control of Foot-and-Mouth Disease to estimate current and future vaccine demand for foot-and-mouth disease at national and regional levels. It uses factors like livestock population forecasts, disease control policies, vaccination schedules, and outbreak forecasts with data from sources like WOAH and FAOSTAT. The model provides outputs on expected vaccine doses needed by geography, type of vaccination, species, and year over a 10-year period. While validation is needed, the tool generally predicts vaccine needs within calculated ranges, though estimates are sometimes too high. Future work will refine inputs, add additional geographical specificity, and expand the model to other diseases.
This document provides an introduction to vaccine value chains and outlines EuFMD/FAO initiatives to strengthen vaccine security. It discusses how vaccine value chains involve both private and public actors across product development, production, allocation, distribution and use. Cross-cutting factors like epidemiology, logistics and stakeholder engagement are also important. EuFMD is supporting activities to improve vaccine access and availability through a multistakeholder platform, prequalification of vaccines, vaccine demand modeling, and strengthening vaccine delivery and demand. Analyzing vaccine value chains can help understand costs and demand to support effective vaccination programs.

Before treatment, schistosomiasis prevalence was very high throughout the area, with one community having over 90% prevalence. IgE antibody levels were inversely related to pre-treatment infection levels. After treatment, prevalence and egg counts declined significantly, with only 3% of households having prevalence above pre-treatment levels. However, several distinct spatial patterns remained related to post-treatment IgE levels and water exposure risk.

RABIES IN TUNISIA:Evolution and result of « National Program of Rabies Control »Pasteur_Tunis
The document summarizes the evolution and results of Tunisia's National Program for Rabies Control. It finds that:
1) Rabies is endemic in Tunisia, primarily spread by dogs. A national program was established in 1983 to control rabies through dog vaccination campaigns, human post-exposure prophylaxis, and rabies surveillance.
2) The program successfully reduced rabies incidence between 1983-1988 and 1993-2010. However, cases have increased again from 2012-2015, calling for improvements to the program, including increasing dog vaccination coverage and public education.
3) The Pasteur Institute Rabies Laboratory plays a key role in epidemiological surveillance and evaluation of control efforts in Tunisia. It
Agriculture, Health and Food-Borne and Zoonotic Diseases - Dr Joachim Otte, FAOLIDC
The document discusses the relationship between agriculture, health, and emerging zoonotic diseases. It notes that intensification of livestock production, human encroachment on wildlife habitats, and increased demand for meat have contributed to increased risk of disease transmission at the wildlife-livestock-human interface. The document also examines trends in disease emergence, including the large number of potential zoonotic viruses yet to be discovered. It argues that an integrated approach across disciplines is needed to address challenges at the agriculture-health nexus.
This document presents a livestock mortality model and vulnerability index (MDVI) developed for Mongolia. The model uses data on winter temperature/snowfall anomalies, forage biomass anomalies, pasture use anomalies, and livestock mortality/productivity scores from 1998-2014. It explains almost two-thirds of historical livestock mortality.
The MDVI was created using the last three variables to produce vulnerability-based early warnings. Four vulnerability classes were established, correlated with average mortality rates and likelihood of severe mortality. The index uses data from the prior year to predict vulnerability and support disaster risk reduction. The model contributes to efforts to better understand and forecast dzud risk in Mongolia.

What variables are important in predicting bovine viral diarrhea virus? A ran...University of Minnesota
The random forest algorithm was used to analyze data from a bovine viral diarrhea virus (BVDV) prevalence study and identify important predictors of BVDV occurrence. A random forest model was trained on data from 388 dairy farms tested for BVDV. Variable importance analysis identified the most important predictors of BVDV as who inseminates the animals on the farm, the number of neighboring farms with cattle, and whether rectal palpation was routinely performed. The random forest model had an error rate of 32.03% for correctly predicting negative farms and 36.78% for positive farms, with an area under the ROC curve of 0.702. This study demonstrated that random forest is a useful machine learning method for epidemi

This document evaluates Albania's surveillance system for diarrheal diseases from 1998-2009. It finds that the system produces low quality data with incomplete, inaccurate, and slow reporting. There is a discordance between monthly reporting numbers and individual case reporting. The system lacks standardization and flexibility. Younger age groups and urban populations have higher rates of diarrheal diseases. Improvements are needed to drinking water safety and sanitation.
One Health Epidemic Risk Management in Kazakhstan With Open-source Eidss Al...Global Risk Forum GRFDavos
Kazakhstan faces risks from diseases such as plague, tularemia, and anthrax. The authors propose developing a Regional Sanitary-Epidemiological Passport (RSEP) to assess epidemic risks in each district of Kazakhstan. The RSEP would use data on infectious disease rates, population counts, and other factors to generate forecasts of risk levels for diseases over 1-2 years. An open-source Electronic Integrated Disease Surveillance System (EIDSS) would collect case data to feed into the RSEP models. The authors plan to develop and validate the RSEP approach over several stages focused on different regions of Kazakhstan.

VADEMOS VAccine Demand Estimation Model for FMD.pdfEuFMD
VADEMOS is a decision support tool created by the European Commission for the Control of Foot-and-Mouth Disease to estimate current and future vaccine demand for foot-and-mouth disease at national and regional levels. It uses factors like livestock population forecasts, disease control policies, vaccination schedules, and outbreak forecasts with data from sources like WOAH and FAOSTAT. The model provides outputs on expected vaccine doses needed by geography, type of vaccination, species, and year over a 10-year period. While validation is needed, the tool generally predicts vaccine needs within calculated ranges, though estimates are sometimes too high. Future work will refine inputs, add additional geographical specificity, and expand the model to other diseases.
This document provides an introduction to vaccine value chains and outlines EuFMD/FAO initiatives to strengthen vaccine security. It discusses how vaccine value chains involve both private and public actors across product development, production, allocation, distribution and use. Cross-cutting factors like epidemiology, logistics and stakeholder engagement are also important. EuFMD is supporting activities to improve vaccine access and availability through a multistakeholder platform, prequalification of vaccines, vaccine demand modeling, and strengthening vaccine delivery and demand. Analyzing vaccine value chains can help understand costs and demand to support effective vaccination programs.
Emergency vaccination workshop presentations 30 May 2023.pdfEuFMD
This document summarizes a presentation on alternative post-vaccination surveillance methods that could be used to demonstrate the absence of foot-and-mouth disease (FMD) virus transmission in vaccinated and unvaccinated livestock populations. It proposes replacing serological testing with bulk milk testing for dairy farms, saliva testing using rope tethers for piggeries, and saliva swab testing for sheep farms. These alternative methods utilize real-time reverse transcription polymerase chain reaction to detect FMD viral RNA from oral fluid samples, which research has shown can identify infected animals. The presentation discussed how these new testing technologies may allow countries to gain freedom from FMD status sooner after an outbreak by providing more effective post-vaccination surveillance.

The document discusses subclinical infection and its role in the transmission and epidemiology of Lumpy Skin Disease Virus (LSDV). It presents the body temperatures of experimental animals infected with LSDV over time. One animal showed clinical signs of LSDV while another showed viremia or presence of the virus in the blood without displaying clinical signs, representing a subclinical infection. The conclusion is that subclinical infection from vaccine-like recombinant LSDV can play a role in transmission of the virus.

1) Lumpy skin disease was first reported in Indonesia in February 2022 in Riau Province, and has since spread to several other provinces, most recently to Central Java in August 2022.
2) As of February 2023, over 249,000 cattle have been vaccinated across 9 provinces as a control measure. Other control measures include movement restrictions, vector control, and educating farmers.
3) Key challenges to control efforts include the extensive animal farming system, illegal animal movement, limited number of vaccinators, and high workload from controlling both lumpy skin disease and foot-and-mouth disease. Recommended solutions include improving handling capacity, better border control, engaging other institutions to assist with vaccination

Lumpy Skin Disease (LSD) is spreading through cattle movements in Southeast Asia. The document discusses how government policies around quarantine, compensation and corruption can accelerate the virus's spread by encouraging illicit cattle movements. It also notes that traditional smuggling routes go against the direction LSD has spread. The rapid transmission of LSD occurred during COVID border closures, and its direction of movement corresponds with prevailing winds rather than cattle trade routes. Government policies and wind patterns may be aiding the long-distance airborne spread of LSD across Southeast Asia.
LSD symposium - P. Malik - Lumpy skin disease experience from IndiaEuFMD
Lumpy Skin Disease (LSD) was first reported in India in 2019. It has since spread to 23 states and union territories, affecting over 3 million animals and causing over 185,000 deaths. The disease manifests as skin nodules and lesions on internal organs. Vaccination is a key control strategy, with over 87 million animals vaccinated to date using a goatpox vaccine. ICAR has also developed an indigenous LSD vaccine that is undergoing field trials and licensing. States are implementing control measures like quarantine, vaccination, vector control and public awareness campaigns to curb the spread and impact of LSD.
LSD symposium - E. Klemen - Modes of transmission of lumpy skin diseaseEuFMD
Indirect transmission, likely through blood-sucking flying insects, is the primary mode of transmission for lumpy skin disease virus. While direct contact can transmit the virus, studies have found no transmission between clinically infected and susceptible cattle housed together without vectors. Mathematical models also indicate indirect transmission alone can explain outbreak dynamics. The virus can spread over long distances, possibly aided by winds carrying infected vectors, though local spread is typically 10 km per week. Subclinical infections may transmit the virus but appear to play a minor role compared to clinical cases.

Storyboard on Skin- Innovative Learning (M-pharm) 2nd sem. (Cosmetics)MuskanShingari
Skin is the largest organ of the human body, serving crucial functions that include protection, sensation, regulation, and synthesis. Structurally, it consists of three main layers: the epidermis, dermis, and hypodermis (subcutaneous layer).
1. **Epidermis**: The outermost layer primarily composed of epithelial cells called keratinocytes. It provides a protective barrier against environmental factors, pathogens, and UV radiation.
2. **Dermis**: Located beneath the epidermis, the dermis contains connective tissue, blood vessels, hair follicles, and sweat glands. It plays a vital role in supporting and nourishing the epidermis, regulating body temperature, and housing sensory receptors for touch, pressure, temperature, and pain.
3. **Hypodermis**: Also known as the subcutaneous layer, it consists of fat and connective tissue that anchors the skin to underlying structures like muscles and bones. It provides insulation, cushioning, and energy storage.
Skin performs essential functions such as regulating body temperature through sweat production and blood flow control, synthesizing vitamin D when exposed to sunlight, and serving as a sensory interface with the external environment.
Maintaining skin health is crucial for overall well-being, involving proper hygiene, hydration, protection from sun exposure, and avoiding harmful substances. Skin conditions and diseases range from minor irritations to chronic disorders, emphasizing the importance of regular care and medical attention when needed.
Part III - Cumulative Grief: Learning how to honor the many losses that occur...bkling
Cumulative grief, also known as compounded grief, is grief that occurs more than once in a brief period of time. As a person with cancer, a caregiver or professional in this world, we are often met with confronting grief on a frequent basis. Learn about cumulative grief and ways to cope with it. We will also explore methods to heal from this challenging experience.
Congestive Heart failure is caused by low cardiac output and high sympathetic discharge. Diuretics reduce preload, ACE inhibitors lower afterload, beta blockers reduce sympathetic activity, and digitalis has inotropic effects. Newer medications target vasodilation and myosin activation to improve heart efficiency while lowering energy requirements. Combination therapy, following an assessment of cardiac function and volume status, is the most effective strategy to heart failure care.
Understanding Atherosclerosis Causes, Symptoms, Complications, and Preventionrealmbeats0
Definition: Atherosclerosis is a condition characterized by the buildup of plaques, which are made up of fat, cholesterol, calcium, and other substances, in the walls of arteries. Over time, these plaques harden and narrow the arteries, restricting blood flow.
Importance: This condition is a major contributor to cardiovascular diseases, including coronary artery disease, carotid artery disease, and peripheral artery disease. Understanding atherosclerosis is crucial for preventing these serious health issues.
Overview: We will cover the aims and objectives of this presentation, delve into the signs and symptoms of atherosclerosis, discuss its complications, and explore preventive measures and lifestyle changes that can mitigate risk.
Aim: To provide a detailed understanding of atherosclerosis, encompassing its pathophysiology, risk factors, clinical manifestations, and strategies for prevention and management.
Purpose: The primary purpose of this presentation is to raise awareness about atherosclerosis, highlight its impact on public health, and educate individuals on how they can reduce their risk through lifestyle changes and medical interventions.
Educational Goals:
Explain the pathophysiology of atherosclerosis, including the processes of plaque formation and arterial hardening.
Identify the risk factors associated with atherosclerosis, such as high cholesterol, hypertension, smoking, diabetes, and sedentary lifestyle.
Discuss the clinical signs and symptoms that may indicate the presence of atherosclerosis.
Highlight the potential complications arising from untreated atherosclerosis, including heart attack, stroke, and peripheral artery disease.
Provide practical advice on preventive measures, including dietary recommendations, exercise guidelines, and the importance of regular medical check-ups.
Storyboard on Acne-Innovative Learning-M. pharm. (2nd sem.) CosmeticsMuskanShingari
Acne is a common skin condition that occurs when hair follicles become clogged with oil and dead skin cells. It typically manifests as pimples, blackheads, or whiteheads, often on the face, chest, shoulders, or back. Acne can range from mild to severe and may cause emotional distress and scarring in some cases.
**Causes:**
1. **Excess Oil Production:** Hormonal changes during adolescence or certain times in adulthood can increase sebum (oil) production, leading to clogged pores.
2. **Clogged Pores:** When dead skin cells and oil block hair follicles, bacteria (usually Propionibacterium acnes) can thrive, causing inflammation and acne lesions.
3. **Hormonal Factors:** Fluctuations in hormone levels, such as during puberty, menstrual cycles, pregnancy, or certain medical conditions, can contribute to acne.
4. **Genetics:** A family history of acne can increase the likelihood of developing the condition.
**Types of Acne:**
- **Whiteheads:** Closed plugged pores.
- **Blackheads:** Open plugged pores with a dark surface.
- **Papules:** Small red, tender bumps.
- **Pustules:** Pimples with pus at their tips.
- **Nodules:** Large, solid, painful lumps beneath the surface.
- **Cysts:** Painful, pus-filled lumps beneath the surface that can cause scarring.
**Treatment:**
Treatment depends on the severity and type of acne but may include:
- **Topical Treatments:** Such as benzoyl peroxide, salicylic acid, or retinoids to reduce bacteria and unclog pores.
- **Oral Medications:** Antibiotics or oral contraceptives for hormonal acne.
- **Procedures:** Such as chemical peels, extraction of comedones, or light therapy for more severe cases.
**Prevention and Management:**
- **Cleanse:** Regularly wash skin with a gentle cleanser.
- **Moisturize:** Use non-comedogenic moisturizers to keep skin hydrated without clogging pores.
- **Avoid Irritants:** Such as harsh cosmetics or excessive scrubbing.
- **Sun Protection:** Use sunscreen to prevent exacerbation of acne scars and inflammation.
Acne treatment can take time, and consistency in skincare routines and treatments is crucial. Consulting a dermatologist can help tailor a treatment plan that suits individual needs and reduces the risk of scarring or long-term skin damage.

The force of infection, λ𝑖 𝑡 , (i.e., the rate at which uninfected herds become infected) was modelled (Eq.)
and explored by using a kernel-based approach. The best-fit transmission kernel for the Albanian outbreak
data was a fat-tailed one. Most transmission occurs over short distances (<5 km) (Fig. a). Therefore,
proximity to affected farms can be considered a risk factor for LSD spread (Gubbins et al., 2020; EFSA,
2018). In addition, there is an appreciable probability of transmission at longer distancing, which can be
attributed to livestock movements (Fig. b) (Gubbins et al., 2020).

𝐾(𝑑𝑖𝑗)𝑁𝑗𝐼𝑗(𝑡)
h = the transmission rate;
𝑁𝑖 𝑁𝑗 = the number of cattle herds 𝑖 and 𝑗, respectively;

𝐼𝑗(𝑡) = a variable indicating whether herd 𝑗 is uninfected (0) or infected
(1) on day 𝑡.
Transmission kernels for LSDV plotted on a (a) linear or (b) logarithmic scale (Gubbins et al., 2018).
▪ (Fig. a) The fat-tailed, exponential, and Gaussian kernels predicted the risk of transmission
reduced by 95% at a distance of 4.1 km, 7.2 km, and 12.1 km, respectively.
▪ (Fig. b) The fat-tailed kernel (the best fitted to data) predicts more transmission at distances
over 20 km than the exponential or Gaussian one.

Evidence for seasonal variation in the force of infection associated with temperature (Fig. c) and modeled
relative vector abundance (Stomoxys calcitrans) (Fig. d), and the significant decline in the basic
reproduction number (R0) during the epidemic (Fig. e) suggest the seasonality in the LSDV transmission
and that the related abundance of potential LSD vectors is the major risk factors contributing to LSD
spread (Gubbins et al., 2020; EFSA, 2019).

▪ The Albanian veterinary service faced technical and administrative challenges to control Lumpy Skin
Disease. Re-organization to deliver a modern veterinary service initiated.
▪ The commitment, collaboration, and assistance of national, regional, and international stakeholders
(European Commission, EFSA, FAO, IAEA and WOAH) were the main elements that allowed the
achievement of the results for the surveillance and control of the LSD.
▪ High-quality data is a cornerstone for epidemiological analysis and disease control, and improved
computerized data collection is needed.
▪ Laboratory diagnostic real-time PCR, which differentiates the LSD field virus from the vaccine strain, is
important for disease surveillance during the vaccination period.
▪ Further work is required to incriminate specific species as vectors of LSDV.
▪ Achieving the highest uniform vaccination coverage with the live attenuated homologous Neethling
vaccine in the shortest period of time is the cornerstone to rapidly control LSD outbreaks.
