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.
Abstract:
There are limited data on SARS-CoV-2 testing practices and positivity among children and adults affected by HIV. The Pediatric HIV/AIDS Cohort Study enrolls children, youth, and adults with perinatally-acquired HIV (PHIV), non-perinatally-acquired HIV (NPHIV), perinatal HIV exposure but uninfected (PHEU), and infants/children with PHEU across the United States and Puerto Rico. A Health Status Survey was developed and administered from April 2020 to November 2021 to assess cumulative incidence (%) of self-reported (1) SARS-CoV-2 testing uptake and results by HIV status, age, and pandemic period; (2) moderate and severe respiratory illness; and (3) hospitalization. At least one survey was completed for 2,289 participants (PHIV = 444, NPHIV = 644, PHEU = 1201) through November 2021; 62% identified as Black and 33% as Hispanic. Participants' ages (years) ranged from 18-42 in PHIV, 19-57 in NPHIV, and < 1-28 in PHEU. Among PHIV, NPHIV, and PHEU, respectively, 43%, 35%, and 16% reported SARS-CoV-2 testing; of these, 18%, 16%, and 11% testing positive. The proportion tested was similar by race, Hispanic ethnicity, education, and income. Overall, 4% (87/2289) were hospitalized for any illness. 8% (174/2289) reported a respiratory illness "worse than the common cold," of whom 44% (76/174) reported SARS-CoV-2 testing, 49% (37/76) testing positive, and 13% (23/174) were hospitalized. The cumulative incidence of both SARS-CoV-2 positivity and severe COVID-19 disease as of November 2021 was lower than expected among persons affected by HIV. Testing access, uptake, and mitigation strategies in this population may explain these findings and inform strategies to prevent acquisition of respiratory viruses.Trial Registration Not applicable; this is not a clinical trial.

Sputum Studies II: Culture and Sensitivity
Sputum culture and sensitivity is a medical procedure used to diagnose bacterial infections in the respiratory tract and select the most appropriate antibiotics for treatment. This process involves analyzing sputum samples of thick and opaque secretions produced in the lungs and airways. These samples are collected from patients and then sent to the laboratory for analysis.
The test can identify various pathogens responsible for respiratory infections, including Streptococcus,...
