PREVALENCE OF HBV AND HCV; AND THEIR ASSOCIATED RISK FACTORS AMONG PUBLIC HEALTH CENTER CLEANERS AT SELECTED PUBLIC HEALTH CENTERS IN SANA'A CITY-YEMEN
Occupational exposure of public health center cleaners (PHCCs) to blood and body fluids after skin injury or mucous membrane contact constitutes a risk for transmission of blood-borne pathogens. In the industrialized world, occupational surveillance is performed to assess and monitor health hazards related to blood borne pathogens. In contrast, in developing countries as Yemen, exposure and health impacts are rarely monitored and much remains to be done to protect PHCCs. The objective of this study was to determine the prevalence of HBV and HCV and their potential risk factors among PHCCs. A cross sectional prospective study was conducted among 388 PHCCs. Data was collected using pre-tested and structured questions. Venous blood was collected and the sera were tested for HBV surface antigen and anti-hepatitis C antibodies using enzyme-linked immune sorbent assay technique. The data were analysis by EPI-Info. Chi square and Odds ratio tests were used to assess the association of risk factors with HBV and HCV positivity. Results revealed that among the total 388 PHCCs examined, HBV and HCV were detected in 32 (8.2%), and 4 (1.03%) of them respectively. There was significant risk factors of hepatitis viruses with age group 20-24 years (OR=2.8), exposure to patients blood (OR=3), accidental stick of used needles (OR=2.3), sharp injury (OR=5.6), history of blood transfusion (OR=2.5), and hospital admission (OR=2.7). Also significant protected roles for HBV vaccine was found with infection. In conclusion high prevalence rates of HBV and HCV occurred in PHCCs. Unfortunately; all workers did not take training on medical waste and few workers use protective measures consistently as vaccination. There is needed to make vaccination of health care workers against HBV infection a firm policy and ensure complete and consistent adherence to work standard safety measures.
