ABSTRACT
Coronavirus disease 2019 (COVID-19) and associated social responses may uniquely affect people living with HIV (PLHIV). SARS-CoV-2 antibody testing and a cross-sectional survey on COVID-19's socio-behavioral impacts were conducted among a large PLHIV cohort in Hanoi, Vietnam. We examined anonymous antibody test results for 1243 PLHIV (99.8%) from whom plasma was obtained and completed surveys were collected in June/July 2020, just after the end of the first COVID-19 outbreak and nationwide lockdown. Three participants (0.2%) tested positive for anti-SARS-CoV-2 IgG antibodies. HIV treatment was generally maintained without antiretroviral therapy interruption, but COVID-19 had substantial impacts on economic security and risky health behaviors among PLHIV, which may have amplified psychological stress. These findings highlight the need for continuous monitoring of COVID-19's impacts on PLHIV and for efforts to mitigate these impacts.
