Epidemiology of hepatitis b

  1. 1.  Hepatitis B virus (HBV) infection is a major public health problem in the Middle East. The majority of the countries in the region have an intermediate or high endemicity of HBV infection.
  2. 2. PREVALENCE OF HBV CARRIER STATUS  Classification of countries based on HBsAg +ve carriers: ≤2% •Low Endemicity •Intermediate2% - 5% Endemicity ≥5% •High Endemicity
  3. 3. STATUS IN HEPATITIS B CARRIER RATES AND VACCINATION MIDDLE EAST COUNTRIES HBsAg HB VaccinationCountry carrier vaccine Coverage % in EPIBahrain 0.9 – 1.25 YES 89 Iran 1 YES 81Kuwait 1.5 YES 94 Israel 1 YES 92
  4. 4. STATUS IN HEPATITIS B CARRIER RATES AND VACCINATION MIDDLE EAST COUNTRIESCOUNTRY HBsAg HB vaccine Vaccination carrier % in EPI CoverageCyprus 2-2.5 Yes 68Iraq 4-5 Yes 59Libya 2-6 Yes -Emirates 2-5 Yes 90
  5. 5. HEPATITIS STATUS IN COUNTRY HBsAg HB vaccine Vaccination carrier % in EPI Coverage B CARRIER RATES AND VACCINATION Egypt 3-11 Yes 82 MIDDLE EAST COUNTRIES Jordan 3-10 Yes 90 Oman 2-10 Yes 99 Palestine 5-6 Yes - Sudan 16-20 No -Saudi Arabia 7-17 Yes 95 Tunisia 6-7 Yes - Yemen 12-18.5 Yes 42
  6. 6. MODE OF TRANSMISSION HBV can be transmitted at perinatal, childhood or adult ages. The main modes of transmission are mother-to- child, child-to-child, sexual and parenteral.
  7. 7. MODE OF TRANSMISSION IN THE MIDDLE EAST the majority of infections occur through childhood and perinatal transmission. There is limited information on sexual transmission in Middle East societies. Parenteral transmission in health institutions should be limited due to routine screening of blood products. The number of intravenous drug users in the Middle East remains low compared to other regions, but there is little information on unsafe injection practices.
  8. 8. MOTHER-TO-CHILD TRANSMISSION BY HBEAG Number % of STATUS IN NumberStatus tested of positive positive tested babies babies HBsAg- 120 HBSAG-POSITIVE MOTHERS positive 25 21 (100%) mothers HBeAg- positive 16 (13%) 15 94 mothers HBeAg- negative 104 (87%) 10 10 mothers
  9. 9. FACTORS ASSOCIATED WITH HBV INFECTION Family size, Age at infection Socioeconomic status, Educational status and History of previous blood transfusion, surgery or contact with a jaundiced person.
  10. 10. PREVENTION OF HBV INFECTION Active immunization (universal and targeted), Routine blood screening for HBsAg and ensuring of safe injection practices. Passive Immunization using hepatitis B immunoglobulin (HBIG) is not common in the Middle East because the majority of chronic carriers result from childhood transmission, the cost is high and there is a large proportion of home deliveries in many Middle East countries. Safe sex is not officially promoted in most countries of the region for cultural reasons.
