Insights

Individuals with HIV showed lower than expected SARS-CoV-2 positivity and severe COVID-19 disease. Testing access and mitigation strategies likely contributed to these findings in the HIV-affected population.

Area of Science:

  • Public Health
  • Infectious Diseases
  • Epidemiology

Background:

  • Limited data exists on SARS-CoV-2 testing and positivity rates among children and adults living with HIV.
  • The Pediatric HIV/AIDS Cohort Study (PHACS) collects data on individuals with perinatally-acquired HIV (PHIV), non-perinatally-acquired HIV (NPHIV), and perinatal HIV exposure but uninfected (PHEU).

Purpose of the Study:

  • To assess SARS-CoV-2 testing uptake, positivity, and respiratory illness incidence in an HIV-affected cohort.
  • To evaluate the cumulative incidence of SARS-CoV-2 testing, positivity, and hospitalization by HIV status and pandemic period.

Main Methods:

  • A Health Status Survey was administered to 2,289 participants (PHIV, NPHIV, PHEU) from April 2020 to November 2021.
  • Data collected included self-reported SARS-CoV-2 testing, results, respiratory illness severity, and hospitalization.
  • Analysis considered HIV status, age, race, Hispanic ethnicity, education, and income.

Main Results:

  • SARS-CoV-2 testing was reported by 43% of PHIV, 35% of NPHIV, and 16% of PHEU participants.
  • Positivity rates among those tested were 18% (PHIV), 16% (NPHIV), and 11% (PHEU).
  • Overall hospitalization was 4%; 8% reported significant respiratory illness, with 49% testing positive for SARS-CoV-2 and 13% hospitalized.

Conclusions:

  • The cumulative incidence of SARS-CoV-2 positivity and severe COVID-19 disease was lower than anticipated in the HIV-affected population.
  • Factors such as testing access, uptake, and implemented mitigation strategies may explain these lower rates.
  • Findings can inform future strategies for preventing respiratory virus acquisition in this vulnerable group.
