Summary
Superinfection, or getting a second HIV infection, is unlikely during initial infection but may occur later. This risk is important for HIV-discordant couples, especially if only one partner has effective treatment.
Area of Science:
- Virology
- Immunology
- Epidemiology
Context:
- Most viral infections confer lifelong immunity, preventing reinfection.
- Recent research suggests viral clade recombination may impact superinfection dynamics.
- The occurrence of superinfection during chronic Human Immunodeficiency Virus (HIV) infection remains uncertain.
Purpose:
- To review current data on HIV superinfection.
- To assess the potential risks of superinfection in different HIV infection scenarios.
Summary:
- While primary viral infections typically induce lasting immunity, the possibility of superinfection with Human Immunodeficiency Virus (HIV) during chronic infection is under investigation.
- Recombination between different HIV clades might influence the likelihood of superinfection during initial infection.
- Superinfection poses a potential risk for HIV-concordant couples, potentially leading to drug-resistant or more virulent strains, disease progression, and treatment failure.
Impact:
- Informing HIV-discordant couples about the theoretical risk of superinfection is crucial, particularly when one partner is on effective antiretroviral therapy.
- Understanding superinfection dynamics is vital for refining HIV prevention and treatment strategies.
- This review highlights the need for continued research into HIV superinfection and its clinical implications.
