Hepatitis E virus (HEV) is a RNA virus transmitted enterically. A study of anti-HEV antibodies in 145 human immunodeficiency virus type 1 (HIV-1) infected subjects found that 14.4% of them were reactive to anti-HEV antibodies. Anti-HEV IgG and anti-HEV IgM was detected in 10.3% and 4.1% of the subjects respectively. Prevalence of anti-HEV (either IgG or IgM) was similar across all adult ages (p = 0.154), between the three ethnic groups (p = 0.378), and across risk groups (p = 0.120). The results showed that HEV infection in subjects recruited in this study was most likely transmitted via faecal-route.
Hema-Strip HIV-1/2 is a one-step rapid test for the detection of anti-HIV-1/2 antibodies in whole blood. The test requires no expensive equipment and the results are available within 10-15 min. Using 72 known HIV-1 positive samples and 780 high-risk prisoners, the sensitivity and specificity of Hema-Strip HIV-1/2 was found to be comparable to microparticle enzyme immunoassay (MEIA). The data also indicated that Hema-Strip HIV-1/2 is an effective alternate testing system to conventional ELISA where the use of ELISA is not suitable and the result of the HIV testing is needed urgently.
