Seropositivity and determinants of immunoglobulin-G (IgG) antibodies against Herpes simplex virus (HSV) types -1 and -2 in pregnant women in Port Harcourt, Nigeria
Background: This study is the first documented prevalence of IgG antibody against HSV-1&-2 in Port Harcourt, Nigeria and thus provides baseline data for future in-depth studies on HSV infection in South-South, Nigeria.
Objective: This study determined the seropositivity and determinants of serum IgG antibody against HSV-1 & HIV-2 among pregnant women attending BMSH, Port Harcourt, Rivers State, Nigeria.
Methods: Serum samples from 180 pregnant women attending antenatal clinic at Braithwaite Memorial Specialist Hospital (BMSH) in Port Harcourt, Nigeria. Serum samples were analysed with commercial HSV type-1&-2 specific IgG Enzyme Linked Immunosorbent Assay (ELISA) kits. Chi-square analysis was used to determine the association of infection with socio-demographic variables.
Results: Of the 180 pregnant women, 179 (99.4%) were seropositive and 1(0.6%) was seronegative for HSV 1&2 IgG antibody. No statistical association existed between the prevalence of HSV-1&-2 IgG antibodies and the socio-demographic variables studied (p>0.05) except for marital status which was significantly associated (p<0.05).
Conclusion: Our data shows that HSV-1 & 2 seropositivity among pregnant women in Port Harcourt is high; thus serological screening for HSV-1&-2 might be advisable for antenatal attendees.
