Insights
People with HIV did not experience worse COVID-19 outcomes than expected, despite immunosuppression. Research explores factors like antiretrovirals and offers prevention strategies for HIV-COVID-19 co-infection.
Area of Science:
- Infectious Diseases
- Immunology
- Public Health
Background:
- COVID-19 disproportionately affects individuals with comorbidities like diabetes, obesity, and cardiovascular disease.
- Persons with human immunodeficiency virus (HIV) were anticipated to face severe COVID-19 due to immunosuppression.
- Observed outcomes in HIV-positive individuals during the pandemic have presented a paradox, prompting further investigation.
Purpose of the Study:
- To review the epidemiology and clinical characteristics of COVID-19 in individuals with HIV.
- To discuss potential factors, including antiretroviral therapy, influencing the clinical course of HIV-COVID-19 co-infection.
- To analyze pandemic-related risks for people with HIV and provide care recommendations.
Main Methods:
- Literature review of existing data on HIV-COVID-19 co-infection.
- Analysis of epidemiological trends and clinical outcomes.
- Synthesis of evidence regarding influencing factors and risk determinants.
Main Results:
- Contrary to expectations, persons with HIV have not shown a consistently higher susceptibility or poorer outcomes for COVID-19.
- Hypotheses regarding the protective role of immunosuppression or antiretroviral use are being explored.
- Other pandemic-related factors may negatively impact individuals with HIV.
Conclusions:
- The clinical evolution of COVID-19 in people with HIV requires further study to understand the observed paradox.
- Evidence-based recommendations are needed for the prevention and management of COVID-19 in the context of HIV care.
- Understanding these dynamics is crucial for optimizing public health strategies during pandemics.
Abstract:
Throughout the COVID-19 pandemic, the main risk factors associated with the progression to severe disease or death have been typically advanced age, diabetes mellitus, obesity, high blood pressure, heart disease, and chronic pneumopathy. Because of their immunosuppression status, persons with HIV were also expected to have a higher susceptibility to infection or a poor clinical evolution. So far, this has not been confirmed to happen, giving way to hypotheses about the role of immunosuppression or the use of antiretrovirals, which could explain this paradox. In this article we present the existing data on the epidemiology and characteristics of HIV-COVID-19 co-infection, discuss the available evidence on the possible factors involved in the evolution of individuals affected by both viruses, analyze other determinants that may negatively affect persons with HIV during the pandemic, and present recommendations for the prevention and care of COVID-19 infection in the context of HIV.

Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
