<p>We enrolled a total of 220 pregnant women LWHIV, with a median age of 32.7 years (IQR: 27.6-37.6). The seroprevalence of HBV, chronic, and acute HBV infection was 10.5%, 10.0%, and 0.5% respectively. Multiparous women [aOR=11.99; 95%CI 1.11-129.01, p=0.040], being infected with syphilis [aOR=27.65; 95%CI 9.07-84.30, p&lt;0.001], and having HIV-1 viral load of 1000 copies/ml and above [aOR=16.00; 95%CI 1.70-150.63, p=0.015] were associated with HBV infection.</p>
