High rates of hepatitis delta virus superinfection/coinfection in balochistan

Hepatitis B carrier rate is still very high in Pakistan, especially in Balochistan, where in some areas almost 16% of the population is positive for HBsAg. Delta virus, also known as hepatitis D virus, only affects those suffering from Hep B infection (HbsAg positive). A study was carried out to check for Hepatitis Delta virus infection in these patients. This study showed that 35% HbsAg reactive patients had either coinfection or superinfection with the Hepatitis delta virus. These rates are much higher than the other studies, and are alarming. Vaccination against Hepatitis B virus can also prevent this infection. Awareness and prevention at community level is required. (author)
