Blood borne transmission was the commonest mode of transmission followed by
perinatal transmission.
William, "Prevalence, correlates and pattern of Hepatitis B among antenatal clinic attenders in Yaounde-Cameroon: Is
perinatal transmission of HBV neglected in Cameroon?" BMC Pregnancy and Childbirth, vol.
The survey, provided in supplementary files (available here), included questions regarding: Demographic characteristics, HIV history, knowledge regarding
perinatal transmission, reported ART adherence, perceived barriers to ART adherence, and interpersonal and relationship questions.
Despite a weak decreasing trend, such prevalence level of chronic HBV infection in pregnant women highlights a persistent risk of HBV
perinatal transmission and encourages the strengthening of the birth dose vaccine coverage against hepatitis B in Lao PDR.
These European guidelines define high risk for
perinatal transmission based on medical factors such as premature labour, absence of peri-partum prophylaxis, and detectable viral load at delivery.
Furthermore, it also aids in reducing the incidence of
perinatal transmission of hepatitis B virus, and formulating hepatitis B immunoprophylaxis to all new born infants of hepatitis B surface antigen positive mothers.
In addition to HIV coinfection, higher maternal viral loads increase the risk of HCV
perinatal transmission. (9) The mechanisms of HCV vertical transmission are incompletely understood, and no effective preventive intervention strategies have been proven.
The
perinatal transmission of HBsAg at 5.4% and the relatively high proportion of HBeAg positive mothers corroborate the reported imminent risk of these mothers to pass the infection to their offspring.8,23,24,26,27,33 This epidemiological situation is aggravated by the absence of a hepatitis B vaccine birth dose policy in the country.
(6.) Panel on Treatment of HIV-Infected Pregnant Women and Prevention of
Perinatal Transmission. Recommendations for Use of Antiretroviral Drugs in Pregnant HIV-1-Infected Women for Matneral Health and Interventions to Reduce Perinatal HIV Transmission in the United States.
(6) To eliminate the risk of
perinatal transmission of HBsAg from mothers to their infants; a program of combined active and passive immunization has been established.
Trends in
perinatal transmission of HIV/AIDS in the United States.
showed that in the absence of ZDV,
perinatal transmission of HIV was 26.6% (95% CI 21.1--32.7%).
