Impact of the COVID-19 pandemic on HIV prevention and care services among key populations across 15 cities in India: a longitudinal assessment of clinic-based data.

ABSTRACT

INTRODUCTION: The COVID-19 pandemic has threatened to diminish gains in HIV epidemic control and impacts are likely most profound among key populations in resource-limited settings. We aimed to understand the pandemic's impact on HIV-related service utilization among men who have sex with men (MSM) and people who inject drugs (PWID) across India. METHODS: Beginning in 2013, we established integrated care centres (ICCs) which provide HIV preventive and treatment services to MSM and PWID across 15 Indian sites. We examined utilization patterns for an 18-month period covering 2 months preceding the pandemic (January-February 2020) and over the first and second COVID-19 waves in India (March 2020-June 2021). We assessed (1) unique clients accessing any ICC service, (2) ICC services provided, (3) unique clients tested for HIV and (4) HIV diagnoses and test positivity. Among an established cohort of PWID/MSM living with HIV (PLHIV), we administered a survey on the pandemic's impact on HIV care and treatment (June-August 2020). RESULTS: Overall, 13,854 unique clients visited an ICC from January 2020 to June 2021. In January/February 2020, the average monthly number of clients was 3761. Compared to pre-pandemic levels, the number of clients receiving services declined sharply in March 2020, dropping to 25% of pre-pandemic levels in April/May 2020 (first wave), followed by a slow rebound until April/May 2021 (second wave), when there was a 57% decline. HIV testing followed a similar trajectory. HIV test positivity changed over time, declining in the first wave and reaching its nadir around July 2020 at ∼50% of pre-pandemic levels. Positivity then increased steadily, eventually becoming higher than pre-pandemic periods. The second wave was associated with a decline in positivity for MSM but was relatively unchanged for PWID. Among 1650 PLHIV surveyed, 52% of PWID and 45% of MSM reported the pandemic impacted their ability to see an HIV provider. MSM had barriers accessing sexually transmitted infection testing and partner HIV testing. CONCLUSIONS: The COVID-19 pandemic led to significant decreases in HIV-related service utilization among key populations in India. This presents an opportunity for increased transmission and patients presenting with advanced disease among groups already disproportionately impacted by HIV.
