Antibodies against hepatitis C virus (HCV) were detected in 18 (23%) of 800 sera from commercial blood donors and 23 (4.6%) of 502 sera from inmates in Metro Manila, the Philippines.
The difference in the antibody prevalence between the two groups was statistically significant (P<0.05).
HCV RNA was detected in 14 (78%) of the 18 antibody-positive sera from blood donors and 19 (83%) of the 23 antibody-positive sera from inmates.
Genotype analysis revealed that HCV-lb (50%) was most common among blood donors, followed by HCV-1a (36%) and HCV-2a (7%). Among inmates, on the other hand, HCV-la (68%) was most common, followed by HCV-1b (11%), HCV-2a (5%) and HCV-2b (5%). Overall, HCV-la and HCV-1b appeared to be predominant among them.
Thus, the genotype prevalence in the Philippines was distinct from those in other Southeast Asian countries such as Thailand, Vietnam and Indonesia, and also distinct from those in the Far East including Taiwan, Mainland China and Japan.
