  6. Seroprevalence of Hepatitis C Among Egyptian Workers 1996 and in the National Survey 1997-1998 60 55 50 47 47 46 41 38 40 36 35 35 35 34 34 32 30 27 27 23 18 20 13 13 10 10 9 8 10 6 0 <05 10 15 20 25 30 35 40 45 50 55 60 >60 National Survey > 10000 Workers > 5000

  7. Prevalence of HCV HBV and HBsAg in Egypt 1996 *Adjusted for +ve predictive value of ELISA 98% specificity and 98% sensitivity).

  8. HCV 16 % 21 % HBV Median Age 26 Median Age 46 25 % HAV Median Age 12 Median Age 34 All -ve Median Age 44 13 % 1 % Mixed HEV 24 % Etiology of Acute Viral Hepatitis in Egypt 1997-2000 Analysis of 1860 Acute hepatitis cases

  9. Hepatitis C Virus Infection in a Community in the Nile DeltaSeroincidence and Risk FactorsCenter for Field and Applied Research Mostafa K. Mohamed, Fatma Abdel-Aziz, Mohamed Abdel-Hamid, Nabiel N. Mikhail, Mostafa Habib , Wagida Anwar , G. Thomas Strickland, Laurence S. Magder, Alan D. Fix, Ismail Sallam

  10. ALT among Village Residents and HCV 1999 %

  12. Over 2 years of follow-up, 2502/ 3394 seronegative (73.7%) followed-up 25 had valid anti-HCV seroconversion 11 had HCV RNA seroconversions RNA Seroconversion Rate 2.7/1000 P.Y. 95% C.L. 1.1-4.3 /1000 P.Y. Anti-HCV seroconversion Rate 6.2 /1000 P.Y. 95% C.L. 3.8 - 8.6 /1000 P.Y.

  14. Notification Systems Notification for Acute Jaundice : National Surveillance in 110 Fever hospitals and referral hospitals A National Cancer Registry with HCC notification in 8 MOHP cancer centers and University Centers Research on use of sentinel surveillance based on blood banks for monitoring changes in community prevalenceby comparing ratios blood banks prevalence with the surrounding communities in 6 geographical locations over 2 years.

  15. Prevenetion Programs 1- Blood Banks : Screening of blood/blood products Central management , Reporting Provision of Lab Equipment Training, supplies, Monitoring 2- Central and Peripheral Infection Control Comittees 3- Development of Guidelines for Infection Control

  16. Prevenetion Programs Cont. • Training of Health Care personnel on : • 1- Safe Injection Practices • 2- Destruction of disposable needles • 3- Proper Disposal of contaminated invasive materials • 4- Proper sterilization of reusable material • 5- Universal precautions and barrier techniques • 6- Proper Counseling of Patients and their families • Public Education :Use of Contaminated materials • Reduce public use of injections Unsafe practices shaving/circumcision

  17. Laboratory /Clinical Networks NO Current Laboratory or Clinical Networks Blood Bank Serology reporting is The only network available Several Liver Disease Societies now collaborate for exchange of experiences but no common network Role of Authorities Cost and Burden of disease

  18. Role of Authorities There are many public calls on authorities including Peoples Assembly to Develop guidelines for patient management Act for control of transmission Provide Public support for provision of treatment of infected individuals Cost and Burden of disease

  19. Role of Authorities cont. MOHP Authorities are Supporting Research projects lead by the Ministry of Health and Universities in collaboration with International Agencies NIH CDC and WHO Physicians Syndicate authorities Organize meetings with national insurance authorities for developing guidelines for patient management News and Media Authorities Raising Awareness for prevention of infection

  20. Cost and Burden of Liver Disease

  21. Changes of Liver Disease Spectrum in Egypt over 70 Years 1930-1980 Schistosomiasis 30 % Hepato-Splenomegaly 1990 HCV 13% 1990-2000 HCV 14% HCC Liver Cirrhosis Death At Age 30-40’s At Age 50-60’s At Age 60-70’s Liver Cell damage Portal Fibrosis, Portal Hypertension Variceal bleeding occurs in ~ 20% of HCV-infected individuals After 20 of Infection Fatal in < 2 years In chronic HCV infection Patients Occurs annually in 4% of Cirrhotic patients Periportal Fibrosis, Portal Hypertension , variceal bleeding occurs in ~ 80% of individuals After 15-20 of Infection

  22. Predicted Chronic Liver Disease in Egypt 1996

  23. Predicted Hepatocellular carcinoma in Egypt 1996

  24. Cost of STD. TTT = ALL ALT 1.5N X 30000 Cost of complication = Annually 10/100 ALT1.5N X 5000 Lost Productivity = Annually 20/100 ALT1.5N X 1500 Cost of YLL = Annually 3/100 ALT1.5N X 20000 Cost of Alternative TTT = Annually All ALT > N X 1000 TTT of All Cases with Viraemia will prevent infection of new cases
