0 likes•986 views

An epidemiological survey was conducted on foot and mouth disease (FMD) outbreaks in Bushehr Province, Iran from 2009 to 2019. The survey found 144 total outbreaks over the 10-year period, with 62% occurring when new FMD virus serotypes emerged in 2009 and 2015. Cattle feedlots and herds with free-range grazing cattle had the highest risk of disease. No significant correlation was found between FMD outbreaks and vaccination rates. The results indicate that FMD occurs at a hypoendemic level in Bushehr Province and that controlling disease in high-risk cattle populations like feedlots is a key factor for disease management.

EuFMD / Open Session

Local government veterinarians in Nakuru County, Kenya described foot-and-mouth disease outbreaks as either "controlled" or "persistent", but there was no clear, standardized definition used. Data collected from various government sources and organizations showed inconsistencies in how outbreaks were categorized and reported nationally. Without a uniform definition of what constitutes an outbreak, disease control programs may be based on inaccurate data and discussions about control efforts cannot be properly harmonized.

EuFMD

1. A survey was conducted of 270 veterinarians from 21 countries neighboring the EU on their knowledge and experience with Bovine Ephemeral Fever (BEF) between 2015-2019. The majority of respondents were official veterinarians. 2. Results showed BEF occurrence was reported in many countries, especially during summer and autumn months. Surveillance and diagnostic capacity for BEF varied between countries. 3. Respondents felt more training was needed on BEF epidemiology, diagnosis and control. Few countries had active surveillance, vaccination programs or classified BEF as a notifiable disease.

EuFMD

This document discusses Turkey's efforts to improve outbreak investigations for foot-and-mouth disease control. A new three-stage outbreak investigation system was developed, categorizing outbreaks by priority level. Trainings were conducted to improve investigation abilities. As a result, over 200 suspected outbreaks were investigated in 2019-2020, with many confirmed. Improved investigations led to the detection of additional unreported outbreaks. The new approach aims to advance Turkey's control of foot-and-mouth disease.

EuFMD

This document summarizes a study on the interference of maternally derived antibodies (MDAs) on foot-and-mouth disease (FMD) vaccination in calves. The study found significant variation in MDA levels between calves in a large dairy farm despite efforts to standardize colostrum administration. It also found that the farm's current vaccination program for calves starting at 2.5 months was appropriate, as delaying vaccination increased susceptibility to infection while earlier vaccination provided no added benefit. The study concludes that heterogeneity in MDAs must be considered to properly tailor vaccination strategies and protect both calves and adult cattle from FMD spread.

EuFMD

The document summarizes a study investigating risk factors for foot-and-mouth disease (FMD) outbreaks in eastern Rwanda. The study found that 40.15% of farmers did not vaccinate calves under 12 months of age, which was associated with increased FMD outbreaks. Having sheep and goats on the same farm was also linked to higher chances of outbreaks. Surprisingly, farms further from the park fence experienced more FMD than those adjacent, possibly due to less impact from transboundary animal movements after the park was fenced in 2013. The study recommends expanding vaccination programs to target both older and younger cattle.

EuFMD

This study investigated foot-and-mouth disease (FMD) outbreaks in 2011 at a bear rescue center in Vietnam. The aims were to estimate epidemiological parameters of FMD in captive bears, analyze risk factors for clinical FMD, and assess the relationship between seroconversion and clinical signs. The results showed that the serial interval of FMD ranged from 4-15 days, suggesting point-source outbreaks with secondary transmission. The mean reproduction number peaked at 5.35, indicating rapid spread. All bears that developed clinical FMD seroconverted, and 35.3% of bears exposed to FMDV showed seroconversion without clinical signs. Younger bears had higher odds of developing clinical FMD. The study

EuFMD

This document summarizes a study on goat movements within South Africa's foot-and-mouth disease protection zone. The study found that 22% of respondents moved new goats into their holdings in the past year, while 56% moved goats out. Focus group discussions identified four locations in the suspended FMD-free zone linked to goat movements from the study area. Many respondents were unaware they needed veterinary permits for animal movements. The findings suggest goats are moved without permits into the FMD-free zone, potentially spreading the virus. The information will help improve disease surveillance and vaccination programs in the FMD protection zone.

A study analyzed the correlation between serological titer levels and protection in pigs vaccinated with foot-and-mouth disease serotype A vaccine. Logistic regression analysis found a correlation between protection ratio percentages and virus neutralization titers in pig sera collected at different time points post-vaccination. Based on the logistic regression curve, the expected percentage of protection for the foot-and-mouth disease type A vaccine could be calculated. A virus neutralization titer of 0.9 log10 was found to be associated with at least 75% protection against infection with the Sea-97/G1 lineage of foot-and-mouth disease virus type A.

EuFMD

The document discusses extending the EuFMDiS model, which simulates the spread of livestock disease in Europe, to include wildlife spread pathways. Specifically, the model was extended to represent the spread and control of classical swine fever in both Spanish domestic pig populations and wild boar populations. The extended model incorporates a new cellular automata-based wildlife disease model to represent the spread of the disease within and between wild boar populations and between wild boar and domestic pig populations. It considers factors like wild boar distribution and behavior as well as biosecurity measures that influence disease transmission.

EuFMD

1. The document discusses the spread of foot-and-mouth disease virus serotype O/ME-SA/IND2001e sub-lineage in Pakistan. This particular strain was first detected in Pakistan in early 2019 and has since spread to 10 administrative units within the country. 2. Foot-and-mouth disease virus has a high mutation rate, which can lead to new strains emerging and posing challenges for disease control strategies. It is also able to spread between geographical areas and into previously disease-free regions. 3. While this strain had been detected outside of India in several other regions prior to 2019, it had not previously been found within Pakistan before the detections in early 2019.

EuFMD

This document summarizes efforts to empower veterinary paraprofessionals in Africa for better control of transboundary animal diseases. It discusses how veterinary paraprofessionals play a critical role in service delivery but often lack proper training, recognition, and regulation. Initiatives by the OIE and EuFMD aim to strengthen competency acquisition and recognition of paraprofessionals by providing guidelines for their training and establishing sustainable service delivery models. This will enhance prevention of diseases like PPR and FMD, working towards the goal of PPR eradication by 2030 and building resilience against animal health emergencies.

EuFMD

The document summarizes genetic characterization of foot-and-mouth disease viruses in Southeast Asia. It analyzed 95 clinical samples collected between 2018-2019 from Vietnam, Laos, and Cambodia. Through 3D qRT-PCR analysis, 40 samples were confirmed positive for foot-and-mouth disease virus. Phylogenetic analysis based on the VP1 gene found that viruses from Cambodia belonged to serotypes O and A, classified as O/ME-SA/Panasia and A/ASIA/SEA-97 genotypes. Viruses from Vietnam and Laos belonged to serotype O, classified as O/ME-SA/Panasia and O/SEA/Mya-98 genotypes. The study provides information on the genetic

EuFMD

The document discusses the use of mathematical models for foot-and-mouth disease (FMD) in disease-free and endemic settings. In emerging outbreaks, models can predict disease spread but have significant uncertainty. Models are better at predicting outbreaks after the first 2-3 weeks when more data is available. In endemic regions, models can identify what is driving transmission and help target data collection to reduce uncertainty. Movement data can also help predict future risk and inform monitoring. While models have limitations early on, sophisticated techniques may help develop optimal control policies over time as an outbreak unfolds.

EuFMD

1. A simulation model was used to analyze the potential epidemiological and economic impact of a foot-and-mouth disease outbreak in two regions of Austria under different control scenarios. 2. The total costs of an FMD outbreak in Austria were estimated between €269-581 million, with the majority from export losses. The impact depends on control measures used, location, and available resources. 3. Current estimated resources for surveillance and cleaning/disinfection in Austria would be insufficient, leading to a longer outbreak. Alternative control strategies like vaccination could more efficiently limit the outbreak.

EuFMD

This document compares different surveillance approaches that could be used to demonstrate freedom from foot-and-mouth disease (FMD) after an outbreak. Epidemiological modeling was used to simulate FMD outbreaks in Australia with and without emergency vaccination. Traditional post-outbreak surveillance based on serological testing was compared to alternative approaches using non-invasive sampling methods like oral swabs and bulk milk testing, along with real-time PCR testing. The results showed the alternative approaches could complete surveillance faster and at lower cost, especially for larger outbreaks, without reducing effectiveness. Alternative FMD surveillance methods have potential to make post-outbreak testing more efficient.

OS20 - Foot-and-Mouth Disease risk mapping in Georgia - Tengiz Chaligava

EuFMD

This document summarizes a risk mapping project in Georgia that aimed to improve risk assessment of foot-and-mouth disease introduction and spread. Several risk factors were identified including live animal markets, migration, export, and import. Districts across Georgia were involved based on these factors. The study found higher animal mobility and risk in Eastern Georgia compared to other areas, confirming the focus of control efforts there. Future risk maps of neighboring countries will allow for better disease risk predictions and targeted control measures.

HOW DO YOU DEFINE A FOOT-AND-MOUTH DISEASE OUTBREAK IN AN ENDEMIC CONTEXT? ...

EuFMD

This study examines inconsistencies in defining and reporting foot-and-mouth disease (FMD) outbreaks in Nakuru County, Kenya. Through workshops with local veterinarians, the researchers developed a working definition of an FMD outbreak as a farmer-reported index case with subsequent cases on neighboring farms. However, discrepancies exist between county-level reports and national laboratory data due to different serotyping results. Additionally, intergovernmental organizations report varying national outbreak numbers. The inconsistencies suggest disease control programs are based on inaccurate surveillance data. The researchers conclude a standardized outbreak definition is needed to support Kenya's FMD control programs.

EuFMD

The document summarizes factors that influence decision-making for foot-and-mouth disease control in Kenya. Key informant interviews revealed inconsistent prioritization of animal disease control, separate lines of strategic guidance and accountability/budgeting, and private veterinarians involved in disease reporting and vaccination outside of official guidance and accountability. There are opportunities to provide more relevant disease data to farmers and veterinarians and ensure information flows in both directions. Strengthening FMD control could include reinforcing programmatic strengths through a participatory national strategy, integrated public-private partnerships, and accountability mechanisms that promote two-way communication.

EuFMD

This document summarizes the monitoring of foot-and-mouth disease virus serotype O in Turkey from 1999 to the present. Two Panasia genotypes of FMDV serotype O have circulated in Turkey during this period. The first, O/ME-SA/Panasia-1, was detected from 1999-2006 and included two subtypes. The second, O/ME-SA/Panasia-2, has been detected since 2006 and includes six subtypes identified since. Vaccine strains have been updated to account for changes in the circulating viruses. International cooperation is important to control future outbreaks as the virus can spread between countries in the same geographic pool.

EuFMD

The document presents a methodology for estimating indirect costs associated with potential outbreaks of transboundary animal diseases (TADs) in Switzerland. The methodology involves collecting qualitative and quantitative data through literature reviews, stakeholder interviews, and disease control legislation to incorporate into an economic model. An economic model including a cost calculator and decision tree model is used to estimate the cost implications of different disease control options and the impact of uncertainty. This methodology allows identification and characterization of indirect consequential costs, which are often more complex but potentially more significant than direct costs. The decision tree model specifically helps select the optimal disease control policy. This methodology could be applied to estimate costs of other TAD outbreaks.

EuFMD

The document describes the development of an analytical model to predict Foot-and-Mouth disease vaccine demand for endemic countries. The model considers factors like livestock population, vaccination coverage percentages, outbreak numbers, and PCP (Progressive Control Pathway) stage to calculate total vaccination needs between prophylactic vaccination, emergency vaccination, and overall. It outlines key data sources and plans for further model development, including accounting for regional differences, livestock sectors, vaccine schedules, and model evaluation.

EuFMD

1. The document describes a tool created to categorize countries according to their level of implementation of foot-and-mouth disease (FMD) control activities, based on data from the Self-Assessment Tool. An expert knowledge elicitation was conducted to develop a weighting system and measure the impact of individual control activities. 2. The hazard ranking tool can discriminate levels of implementation of specific control actions in different countries based on their reported control activities. It may be useful for quickly monitoring a country's progress. 3. The expert knowledge elicitation methodology helped define weightings for activities and collect additional information on FMD prevention, though some expert statements showed low agreement requiring clarification.

OS20 - Compartmentalization as a tool for improved resilience to TADs introdu...

EuFMD

This document discusses using compartmentalization to improve resilience to African Swine Fever (ASF) introductions. Compartmentalization involves defining an animal subpopulation with a different health status than the rest of the country through strict biosecurity and management practices. If ASF outbreaks in the country, the compartment's pig population retains its disease-free status. Key aspects of compartmentalization include meeting international animal health standards, allowing disease-free trade without downtime from outbreaks in other areas, and independence from disease status of small farms and wildlife. Effective compartmentalization requires national standards, governance, oversight, emergency response plans, and compartment-level risk analysis, biosecurity, surveillance, and traceability.

Mapping the risk of Rift Valley fever in Uganda

ILRI

This study analyzed data from Rift Valley fever (RVF) outbreaks and serological surveys in Uganda to map the risk of RVF transmission. Surveillance records, serological surveys of cattle, sheep and goats, and spatial data on climate/ecology were analyzed. Observed outbreaks were mapped to identify occurrence patterns. Serological data were modeled using logistic regression to identify animal-level exposure factors. A geostatistical model predicted spatial patterns of endemic infection. The final serological model was used to predict areas of exposure risk based on ecological variables. Results identified areas at high transmission risk, especially during wet seasons, and pointed to the need for active surveillance in predicted risk areas.

EuFMD

The document analyzes cattle movement data from a Brazilian state to estimate the coverage of its slaughterhouse-based surveillance system for bovine tuberculosis. It finds that slaughterhouses could monitor herds up to 5 trade connections away indirectly. However, 48.5% of premises and 35% of cattle in the state were not covered by the slaughterhouse surveillance system based on the cattle trade network. The aim was to characterize the cattle population covered directly and indirectly by slaughterhouse inspections and identify gaps.

SURVEY ON 10YEARS FOOT AND MOUTH DISEASE OUTBREAKS IN BUSHEHR PROVINCE, IRAN

EuFMD

This document summarizes an epidemiological survey of foot and mouth disease outbreaks in Bushehr Province, Iran from 2009 to 2019. The survey assessed the effectiveness of Iran's foot and mouth disease control program and identified risk factors. It found that the average monthly incidence of outbreaks in the province was between zero and 0.27 cases per 1,000 epidemiological units. Cattle feedlots had the highest risk of outbreaks, with a relative risk of 15.82 compared to other units. Cattle feedlots and grazing areas for cattle herds were identified as high-risk areas. The findings can help improve disease control and risk management strategies.

Foot and mouth disease preventive and epidemiological aspects

Bhoj Raj Singh

FMD: Menace in India Discusses problems of FMD Control in India like: Lack of faith in farmers and veterinarians that FMD can be controlled with vaccination (due to repeated failure of vaccines in quality and vaccination failures resulting in FMD outbreaks). Lack of infrastructure facilities for maintaining the cold chain and efficient transport to the vaccination site. Lack of human resources for handling/ vaccinating livestock. Needs for further researches on diagnosis (Pen-side), disinfection, vaccines and vaccination (affording at least a year immunity, quality vaccine etc.) and control strategies. No-timely investigation or excessively delayed investigation of FMD outbreaks especially those occurring after vaccination. Transparency in vaccine quality monitoring and vaccine purchases. Fear in veterinarians for reporting FMD in their area of operation. False statistics of the disease and vaccination. No legal punitive action against suppliers of substandard FMD vaccines even after the supply of multiple substandard batches of vaccine.
