The document discusses several misunderstood determinants of COVID-19 that have been claimed but lack epidemiological evidence. It questions correlations that have been proposed between COVID-19 outcomes and factors like median age, BCG vaccination rates, religion, and disease burdens. While some correlations appear convincing based on statistics alone, the document argues they ignore important context and exceptions. There have been very few rigorous epidemiological studies of COVID-19 to determine true disease modulators and spread, and many studies have misused non-epidemiological data.

Vector-borne diseases - Dengue outbreak in Madeira Islandbonniefernley
This document summarizes research on a dengue outbreak that occurred in Madeira Island from 2012-2013. Key findings include:
1) The first recorded presence of the mosquito Aedes aegypti in Madeira was in 2005. It has since rapidly dispersed in the southern part of the island.
2) From 2012-2013, there was a major dengue outbreak with over 2,000 probable cases reported across 3 municipalities. No fatalities occurred but 128 people were hospitalized.
3) Entomological studies found that Ae. aegypti in Madeira has high resistance to multiple insecticides. Genetic analysis indicated the population likely originated from a single introduction event from South America.
Threat of dengue in Europe and strategic measures to control its spreadbonniefernley
This document discusses the threat of dengue in Europe and strategic measures to control its spread. It provides statistics on rising global dengue cases and deaths reported to WHO. Several recent outbreaks of dengue and other mosquito-borne diseases in Europe are mentioned, demonstrating the region's susceptibility. The WHO's global strategy for 2012-2020 aims to reduce dengue mortality and morbidity through integrated surveillance, vector control, vaccination and research. The WHO regional office is working with partners to assist countries through surveillance, prevention and control programs. A three-phased approach of controlling vectors, preventing disease, and limiting spread is recommended, involving coordination between public health authorities and community participation.

Analysis of H5N1 Influenza Data in Indonesia and the Needs for Improvement - ...Tata Naipospos
Indonesia has experienced widespread H5N1 avian influenza in poultry and 100 human cases. The virus is endemic in birds across 31 of 33 provinces. Three distinct viral sublineages circulate in different regions of Indonesia. Analysis of viral genetics shows the virus spread across the archipelago along trade routes and evolved distinct regional groups. Improved control of poultry movement and vaccination are needed to reduce virus spread and environmental load.

This document summarizes human surveillance of dengue, chikungunya and West Nile virus in the Veneto Region of Italy from 2010-2013. It found 79 cases of dengue virus, 3 cases of chikungunya virus, and 40 cases of West Nile virus over this period. The majority of dengue and chikungunya cases were imported from endemic areas, while all West Nile virus cases were acquired within Italy. The surveillance provided important information about the transmission and incidence of these arboviruses in the region.
COVID-19 is certainly a newly emerged zoonosis, not yet understood properly thus cases need utmost care in its handling in both in human and animals.

Brief Overview of Global and Regional HPAI Situation 2011Tata Naipospos
The document provides an overview of the global and regional situation of highly pathogenic avian influenza (HPAI) H5N1. It discusses how the virus has been circulating in poultry and wild birds in Asia, Africa, Europe and the Middle East since 2003. While some countries have regained HPAI-free status, the virus remains endemic in poultry in 5 countries and there are still sporadic outbreaks occurring. Human cases also continue to occur sporadically wherever the virus is present in poultry. The majority of poultry outbreaks and human cases have been concentrated in a few Southeast Asian countries. Live bird markets and cross-border trade are risk factors contributing to the virus's persistence in
Comparative antimicrobial activity of aspirin, paracetamol, flunixin meglumin...Bhoj Raj Singh
• Some of the tested drugs (NSAIDs including aspirin, diclofenac, meloxicam & flunixin meglumine) possess broad-spectrum antimicrobial activity but not in therapeutically achievable non-toxic concentrations in the body. Paracetamol was the least effective as antimicrobial similar to pheniramine maleate.
• A few of the NSAIDs may be evaluated as topical use antimicrobials (aspirin, diclofenac & flunixin) being microbial growth inhibitors at 0.128% concentration, similar levels of antimicrobial drugs including antibiotics are often used in topical antiseptic preparations (gels/ ointments/creams/powders/ lotions).
• Studies should be conducted on synergism/ antagonism of NSAIDs with commonly used antibiotics and herbal antimicrobials so that antimicrobial potential of NSAIDs can be therapeutically utilized.
• Susceptibility of bacteria to NSAIDs may be an aid in the differentiation of a few bacteria like Klebsiella and Raoultella; Enterococcus and Streptococcus (meloxicam); Bacillus and Paenibacillus (Diclofenac). However, multicentric studies on a greater number of strains are essential to establish the difference.

Gravity model, Epidemiology and Real-time reproduction number (Rt) estimation...Bhoj Raj Singh
Coronavirus disease (COVID-19) originated in China during the mid of December 2019 caused global havoc. The World Health Organization (WHO) declared the COVID-19 as an International Public Health Emergency on 30th January 2020 and subsequently as a pandemic on 11th March 2020. The disease has affected almost all the countries of the world and as on 30th July 2020 there were 16.5 million cases and 0.65 million deaths are reported. The members of South Asian Association for Regional Cooperation (SAARC) are Afghanistan, Bangladesh, Bhutan, India, the Maldives, Nepal, Pakistan, and Sri Lanka sharing 3% of the world's area and 21% of the world's population. We analysed the COVID-19 data as on 1st July 2020 retrieved from publically available databases. The gravity model is primarily used in the transportation industry and gaining importance in the modelling of the spread of infectious diseases. In this analysis, we observed that higher personal freedom or movement of people is having the greatest effect on the spread of COVID-19 (coefficient = 2.1). The correlation analysis was carried out with COVID-19 cases, health expenditure, poverty, and BCG vaccination, literacy, and population density of the SAARC countries. The COVID-19 positive cases showed a significant (p<0.001) positive correlation (r=0.99) with mortality rate. Similarly, the COVID-19 deaths showed a significant positive correlation with health expenditure (% GDP) (r = 0.58, p<0.05). The other epidemiological factors such as population density/sq km, literacy %, adult population %, and poverty % didn’t show any significant correlation with COVID-19 cases and deaths. The estimation of weekly Real-time reproduction number (Rt) among SAARC countries showed the highest Rt in India (Rt =2.1; 95% CI 2.05 – 2.2) followed by Bangladesh (Rt =1.6; 95% CI 1.5– 1.6). The comparison of Rt indicated that a decrease in the Rt value was noticed in the later stage of the period (past few weeks) among all the SAARC countries compared with the initial stage of infection except Nepal. The analysis indicates that implementation of restrictions, large scale screening and intensive monitoring is mandatory in all countries in order to reduce the Covid-19 spread.
This study examined urinary tract infections (UTIs) in diabetic and non-diabetic patients in Tripoli, Libya. Uropathogens were isolated from 57% of diabetic UTIs and 67.1% of non-diabetic UTIs, with E. coli, Klebsiella spp., and S. aureus being most common. Resistance to multiple antimicrobials was high among isolated uropathogens from both groups. The study found that diabetes was not a significant factor influencing pathogen type, isolation rates, or antibiotic resistance compared to non-diabetics. However, high resistance to commonly used drugs was observed. Ciprofloxacin and cefotaxime were the most appropriate treatment based

Diseases Transmitted Through Fecal Oral RouteEmtui
Diseases transmitted by the fecal-oral route include viral, bacterial, protozoan and helminth infections. Major causes globally and in developing countries include rotavirus, cholera, typhoid, bacterial diarrhea and amoebiasis. Risk factors include lack of access to clean water and sanitation. Prevention strategies center on improving hygiene, water quality and sanitation to break the transmission cycle. Challenges to control include poverty, lack of surveillance and cultural practices.

The World Health Organization and Food and Agriculture Organization of the United Nations are at the forefront of managing public health hazards. Foodborne diseases are caused by pathogenic bacteria or viruses transmitted through contaminated food at any stage from production to consumption, putting infants, children, the elderly and immunocompromised people particularly at risk of gastrointestinal or more serious neurological, immunological or cancerous symptoms. In recent decades, most diseases have been caused by pathogenic bacteria or viruses originating from food animals and animal products, though some are caused by environmental contaminations from chemicals like fertilizers and pesticides. The five keys to safer food explain basic principles to prevent foodborne illness.

This document provides a summary of key information about primary care approaches to treating HIV patients, including:
1) It discusses the history and epidemiology of HIV, modes of transmission, clinical presentations to different specialists, treatment with HAART, and baseline evaluations prior to treatment initiation.
2) Primary care providers should offer ART to patients with CD4 counts <200 or symptoms, consider treatment for counts 200-350, and can defer for asymptomatic patients with counts >350 and low viral loads.
3) When initiating ART, providers should evaluate readiness, ensure adherence, perform baseline testing, and select preferred first-line regimens consisting of 2 NRTIs combined with an NNRTI or PI.
National TB Elimination Programme in India aims to eliminate TB by 2025. TB remains a major public health problem in India, being one of the leading causes of death. In 2019, the estimated TB incidence was 26.4 lakh cases and estimated deaths were 4.45 lakh. There is a large gap between estimated cases and cases notified to the government. Private sector notification is very low. The government's targets are to reduce TB deaths by 90% and cut incidence rate by 80% by 2025 compared to 2015. This will require detecting all TB cases, ensuring treatment completion, preventive measures like contact screening, and building strong public-private partnerships.

Background: Tuberculosis is one of the most ancient infectious diseases caused by Mycobacterium tuberculosis. The population most affected is the young and economically productive one. The social factors include poor quality of life, poor housing, overcrowding, population explosion, under nutrition, lack of education, and last but not the least lack of awareness of cause of illness.
Aims and Objectives:
1. To study the clinical presentation of tuberculosis in patients.
2. To study various risk factors of tuberculosis.
Material and Methods: This study was conducted at selected designated microscopic centre (DMCs) Kanpur Nagar district has a population of 45.73lakh ( Census 2011).All the patients who were registered in the selected DMCs in the last one month of the year 2016 ( between April and May) were taken into consideration for the present study. Data was collected on predesigned and pretested questionnaire using direct personal interview method of patients at DMCs on the DOTS days of the week i.e Monday, Wednesday and Friday. Informed consent of the study subjects was taken before interview. A total of 105 registered patients were interviewed personally and also the treatment card of patients was obtained from their respective DMCs.
Results: Out of 105 cases of tuberculosis which reported at DMCs maximum no. of patients belongs to age group between 21-40 yrs of age group (58%). Majority of cases were married (65.7%) cases. (62%) cases were Hindu by religion and (58%) belongs to other backward caste. In the study we found majority of patient was illiterate (34.3%). Most common clinical presentation was cough, fever and cough with expectoration, anorexia was reported in (61.9 %) of cases (77%) were cigarette/bidi smokers, 60% were tobacco chewer. Diabetes was reported in (12.4%) cases and (3.8%) cases were HIV positive.
This document provides an introduction to epidemiology. It defines epidemiology as the study of disease occurrence and distribution in populations as well as the determinants that influence health states. Descriptive epidemiology involves characterizing disease distribution according to person, place, and time, while analytical epidemiology aims to identify risk factors and causes of disease. Common study designs in epidemiology include observational studies like cohort and case-control studies as well as experimental designs like randomized controlled trials.
HIV/AIDS is caused by the HIV virus which weakens the immune system. It is transmitted through unprotected sex, contaminated blood, sharing needles, and from mother to child during pregnancy, delivery, or breastfeeding. As the virus progresses it can cause opportunistic infections and cancers. India has a large population affected due to transmission among high risk groups like sex workers, clients, and drug users. Prevention methods aim to reduce transmission through awareness, testing, treatment, and vaccination programs.
Welcome and introduction to EFSA's session at FENS 2019EFSA EU
1) EFSA provides scientific advice and risk assessment on food safety issues across the European Union. It has various scientific panels that evaluate topics like nutrition, food additives, and chemical contaminants.
2) EFSA's mandate in nutrition includes setting dietary reference values, providing advice on foods for specific groups like infants, reviewing nutrient sources, and evaluating health claims. Recent work includes advice on sodium levels and updating tolerable upper intake levels for vitamin D in infants.
3) The presentation highlighted EFSA's recent scientific opinion on introducing complementary foods to infants and included speakers discussing challenges setting sodium guidelines and EFSA's approach to reviewing vitamin D levels in infants.

Highlights on the EFSA Scientific Opinion on the appropriate age range for introduction of complementary feeding into an infant's diet, Prof M Fewtrell
This document summarizes a study on establishing dietary reference values (DRVs) for sodium intake. It describes the challenges in determining an adequate and safe sodium intake range due to conflicting evidence on sodium's effects on blood pressure and cardiovascular disease risk. The study used a formal expert knowledge elicitation process and reviewed evidence on sodium balance, blood pressure, and disease risk to determine that a sodium intake of 2.0 g/day represents a level associated with reduced disease risk and ability to maintain sodium balance for most adults. This intake value of 2.0 g/day was established as the safe and adequate level for sodium for the general adult population in the EU.
Methods used to assure high quality study for ERAEFSA EU
This document discusses methods for assuring high quality studies for environmental risk assessments of transgenic plants. It outlines principles for early-tier testing of non-target arthropods, including selecting relevant test species, characterizing the test substance, choosing appropriate exposure levels and durations, including suitable negative and positive controls, and evaluating study results to avoid false positives or negatives. The goal is to generate reliable data that risk assessors can interpret consistently and use robustly in the risk assessment process.

DRIVERS FOR EMERGING ISSUES IN ANIMAL AND PLANT HEALTH
This document discusses the importance of problem formulation in ecological risk assessment (ERA) for genetically modified (GM) crops. It notes that ERA and ecological research have different goals, with ERA aiming to predict no harm rather than make discoveries. Proper problem formulation in ERA involves considering legislation, the risk analysis process, risk context, and protection goals to identify only credible risks. This ensures the ERA focuses on relevant data and regulatory decisions can be made with certainty. The document provides examples of risk scenarios and contextual factors to consider in ERA for GM cotton and canola. It stresses the importance of data quality, sufficiency and relevance for credible ERA conclusions.

In vitro data and in silico models for predictive toxicologyEFSA EU
The SEURAT project is a 7-year, 50 million Euro collaboration between the European Commission and Cosmetics Europe to develop non-animal approaches for repeated dose systemic toxicity testing. It involves over 70 research partners across 16 countries. The project aims to adopt a toxicological mode-of-action framework and use this knowledge to develop complementary in vitro and computational models that can predict toxicity endpoints needed for safety assessment. Key activities include developing genetically engineered cell lines, multi-scale models of organ toxicity, and an adverse outcome pathway knowledgebase to structure toxicity information. The models and data generated will be stored in online repositories to support regulatory safety evaluation.

9. Summary metrics of population
health
• Integrate morbidity and mortality
• Incorporate age and health status of
those affected
• Address incidence, severity and duration
of adverse health consequences
• Disability Adjusted Life Years (DALYs)
– Years of Life Lost (YLL)
– Years Lived with Disability (YLD)
10. DALY = YLL + YLD
Mortality: years of life lost (YLL)
YLL = Sall outcomes ( D x e)
D: number of deaths
e: life expectancy of fatal cases
Morbidity: years lived with disability, weighted for
severity of illness (YLD)
YLD = Sall outcomes ( N x t x w)
N: number of non-fatal cases
t: duration
w: disability weight
12. Methodological choices
• Hazard- and incidence based approach
• By five-year age group when data available
• No age-weighting and discounting
• WHO life table (projected for 2050; life
expectancy at birth 92 years)
• GBD 2010 disability weights with WHO
modification
• Probabilistic assessment to quantify uncertainty
• Presentation at subregional level
14. Source attribution (SA)
• Foodborne hazards can also be
transmitted by other pathways including
the environment (e.g. water, soil, air),
direct contact between humans or by
direct human-animal contact
• Definition of food as used by FERG
‘any substance, whether processed, semi-processed or raw,
which is intended for human consumption, and includes drink,
chewing gum and any substance which has been used in the
manufacture, preparation or treatment of food but does not
include cosmetics or tobacco or substances used only as drugs’
(Codex Alimentarius Commission)
15. SA methodology
• Data for attribution at global scale are
not available
• Twelve hazards are considered 100%
foodborne
• Structured expert elicitation (Cooke’s
classical method) for nineteen hazards
• Specific estimates for each subregion
(regional panels for diarrheal pathogens,
global panels for all other hazards)

25. Global incidence of aflatoxin-related
hepatocellular carcinoma (HCC)
Liu et al., EHP 2010;118:818-824
• Risk assessment approach
– Aflatoxin levels and consumption in contaminated
foods
– Prevalence of hepatitis B virus
– Cancer potency factors (30x higher in HBV+ than in
HBV- individuals)
• Annually, 550,000 - 600,000 new cases of HCC
• 25,000 – 155,000 may be attributable to
aflatoxin (4.6 – 28.2%)
27. Bottom-up or top-down approach?
• Risk assessment (bottom-up) approach assumes that
– Risks are additive or
– HCC background rate (i.e. due to all risk factors not in the model, e.g.
HCV) is the same in all global populations
• Background risk in Guangxi population (basis for cancer
potency factor) higher than in other known regions
• May lead to overestimation of global HCC incidence
• Top down approach: estimate population attributable risk,
apply to HCC incidence – default in global burden studies
• Approx. 4x lower estimates of aflatoxin-associated HCC
incidence and deaths; particularly in Africa
• Validity of either method difficult to assess
• Similar considerations for other cancer endpoints and
cardiovascular disease associated with arsenic and lead
28. Country studies
• Objectives
– Strengthen capacity of countries to conduct burden
of foodborne disease assessments
– Encourage countries to use burden of foodborne
disease estimates
• Tools
– National burden of foodborne disease study
– Hazard selection tool
– Guidance on data collection
– Situation analysis, knowledge translation and risk
communication guidance
29. Pilot country studies
• Albania, Japan, Thailand, and Uganda
• Main data gaps
– Etiology of major syndromes (e.g. diarrhea)
– Incidence to chemicals
– Attribution
• Use of private data (diagnostic labs, food
industry
• Differentiation between foodborne and
waterborne exposures difficult
30. Outputs and timelines
• WHO launch – December 2-3, 2015,
Geneva
– WHO report
– PLOS collection
– On-line interactive tool
– Country study toolkit
– Communication materials
• FERG symposium – December 15-16,
2015, Amsterdam
32. Discussion (1)
• Foodborne hazards cause a wide variety of
diseases, ranging from relatively mild to severe
and life-threatening
• The global burden will be quantified for the
first time
• Many data gaps were identified, creating the
need for imputation, assumptions and expert
elicitation
• Food production is linked to human disease via
mechanisms other than direct transmission of
pathogens through food – One Health
approach
33. Discussion (2)
• FERG results will help to focus control activities
to reduce the burden of foodborne disease
• Burden and priorities vary by region
• Current results are a basis for strategies at the
global, regional and national levels
• National studies are needed to refine current
regional insights
• Concerted effort is needed by all stakeholders
in the food chain, from primary production to
consumers
