The global health COVID-19 pandemic is spreading at an alarming rate. The range of clinical presentations of COVID -19 varies from asymptomatic to severe respiratory distress syndrome or even death. Due to the unidentified number of asymptomatic viral-shedding and pauci- symptomatic people in the community, the total number of infections is uncertain. The currently used diagnostic confirmatory test for COVID-19 is the real –time RT-PCR. Serological testing of IgG antibodies has not been sufficiently evaluated yet. Antibodies to the virus could reveal the true extent of the pandemic and help scientists answer basic questions about COVID -19 natural history and real burden. Serological survey at the community level would measure the herd immunity level and subsequently entails decision makers what actions may actually be working to slow its spread. It is thought that countries where immune people are viewed as a resource early by decision makers are expected to perform comparatively better overtime than the others.
Therefore, this exploratory survey will be conducted over a period of 9 months aiming to study seroprevalence of IgG antibodies to COVID19 among a total of 2000 apparently healthy general population recruited from three different governorates representing Upper and Lower Egypt and frontier governorates with reference to ministry of health case load report, as well as among 500 healthcare workers who had previous contact with confirmed COVID19 patients. A predesigned questionnaire (one for the general population and another one for healthcare workers) will be used to collect data concerning socio-demographic, behavioral, clinical and others data related to COVID-19. IgG antibodies will be detected in serum using ELISA technique. Data will be analyzed and interpreted using appropriate statistical methods. The results of this study are expected to reflect an estimation of the COVID-19 herd immunity level among Egyptian population as well as reveal the real burden of infection by identifying the proportion of the population that have got the disease at a subclinical/ mild or were not identified by the current active surveillance method. Eventually, this would guide public health measures and policies showing where the epidemic is heading, to informatively take the right decisions when it is safe to lift shelter-in-place restrictions and how far away we are from “herd immunity” when the epidemic eventually starts to go to an end.

Assuring safe food resources and combating bacterial diarrheal pathogens are crucial for achieving healthy living in any country. Campylobacter spp. is possibly the most common bacterial zoonotic pathogen worldwide. Infected humans exhibit a range of clinical symptoms from mild, watery diarrhoea to severe inflammatory diarrhoea. In Egypt, Campylobacter is a leading cause of paediatric diarrhoea with infants and one year olds experiencing 1.2 and 0.4 episodes per year, respectively. In such hyper-endemic settings, the burden of Campylobacter diarrhoea could be substantial. The gap of knowledge about the epidemiology of Campylobacter in food sources hinders accurate assessment of the human health burden.
The specific tasks of this project were:
Task 1- To generate baseline survey data on prevalence and counts of Campylobacter in retail chicken meat, the most important source of campylobacteriosis, in Alexandria governorate in Egypt;
Task 2- To study the clonal population structure and genotypic diversity of Campylobacter jejuni isolates generated from the baseline survey (Task 1) in Alexandria governorate in Egypt;
Task 3- To characterize antimicrobial resistance patterns in a subset of Campylobacter jejuni isolated from retail broiler meat sampled from Alexandria markets;
Task 4- To screen for virulence and neuropathy associated determinants in a subset of Campylobacter jejuni isolated from retail broiler meat sampled from Alexandria markets;
Task 5- To develop a probabilistic quantitative assessment model for human campylobacteriosis infection risk arising from consumption of broiler meat in the setting of Alexandria, Northern Egypt.

The value of developing a simplified tool to assess HCV risk has been demonstrated in literature. This tool could diminish the need for antibody screening in patients who are at very low or no risk. Widespread use of the tool may facilitate and increase overall screening and detection of HCV. By targeting only patients at higher risk, it may lead to more cost-effective screening for a disease that is causing significant morbidity and mortality particularly in highly endemic area with poor resources like Egypt. Moreover, earlier identification in the course of the disease is associated with better efficacy. Early diagnosis together with patient education and subsequent lifestyle modifications may reduce the risk of transmission of HCV infection to other individuals. Improved understanding of prevalence rates in particular populations will allow resources to be focused where they are needed. Finally, treatment earlier in the course of the disease is associated with acceptable cost per quality-adjusted life years estimates. Therefore, this study was conducted to determine the risk factors beyond HCV endemicity in Egypt through a case-control study. A model of significant risk factors was developed along with a meta-analysis(1) for HCV risk factor globally and in Egypt. The model was validated in a cross-sectional study. An impact analysis and cost-effectiveness (2) estimation of the model was done. The validated tool was applied through the media and internet to recruit high risk individuals for early detection. Throughout the study, awareness was targeted using different tools including media and internet. They were an integrated part wherever using the screening tool and elsewhere. Some of the media can be watched on our youtube channel (VirusC Egypt - YouTube) or accessed through our facebook page (undefined). The study results were published in scientific journals.(1-8)

- To assess the prevalence of snail infection in correlation to environmental factors.
- To carry out a malacological survey of the intermediate host seasonally.
- To evaluate the role of socio-economic and behavioral factors affecting the prevalence of S. mansoni infection.
Prevalence of S. mansoni infection was significantly higher during summer (19.1%) than during fall (7.2%), p <0.01. The intensity of infection (light, moderate, and high) during summer versus fall was (93.55% vs 89.38%, 6.45% vs 8.85, and 0.00% vs 1.77%), p<0.05. Higher prevalence of human infection was identified among males than females (OR=1.63), children aged 11-15 years than among counterparts aged 6-10 years, (OR=2.96), and if mothers were of low educational level (OR=2.83). The main identified risk factors were contacting the main body of water-canal for either washing clothes, land irrigation, collecting waters, bathing, and garbage disposal, p<0.05. The count of collected Biomphalaria Alexandrina was statistically different across seasons (p<0.01) in conjugation with a similar significant difference in water temperature, salinity, turbidity, total coliforms concentration, depth, velocity, and level, p<0.01. Presence of grasses and duckweeds had a significant association with snail infection (p = 0.00l). Water depth, pH, temperature, and total dissolved salts (TDS) significantly affected the snail count.

This study aimed at:
- To determine the prevalence of S. mansoi in a single stool sample collected from the study group by Kato-Katz and PCR.
- To evaluate the validity of and performance of PCR in detection of S. mansoni.
- To determine the prevalence of S. mansoni after conventional therapy with PZQ.
The prevalence of S.mansoni after examination of single stool sample of 347 individuals aged (5-15 years old) based on four slides KK was (106/347) 30.5%. Regarding intensity of infection 87.7% of infected children were of low intensity meanwhile, high and moderate infection represented 5.7% and 6.6% respectively. The wet mount had a sensitivity and PPV of 5% and 40%, respectively, and had a specificity and NPV of 98.5% and 85.5%, respectively. Cohen’s Kappa coefficient (k) was 0.05 indicates poor agreement between wet mount and KK test. The cPCR had a sensitivity and PPV of 25.7% and 100%, respectively, and had a specificity and NPV of 100% and 71.4%, respectively. Cohen’s Kappa coefficient (k) was 0.31 which indicates poor agreement between cPCR and KK technique.
