چکیده
Worldwide, 16 cases of HIV-1 superinfection in humans have been reported since 2002. Superinfection is defined as the reinfection of an individual who already has an established infection with a heterologous HIV strain. Controversy exists surrounding superinfection, because it has implications concerning our understanding of worldwide HIV diversity, individual immunity and disease progression, and vaccine development. Here, we review the current understanding of HIV superinfection.

Chronic HIV-1 Infection Frequently Fails to Protect against Superinfection
Reports of HIV-1 superinfection (re-infection) have demonstrated that the immune response generated against one strain of HIV-1 does not always protect against other strains. However, studies to determine the incidence of HIV-1 superinfection have yielded conflicting results. Furthermore, few studies have attempted to identify superinfection cases occurring more than a year after initial infect...
متن کاملDrug induced superinfection in HIV and the evolution of drug resistance.
The rapid evolution of HIV drug resistance is a major cause of AIDS treatment failure. Superinfection, the infection of an already infected cell by additional virions, can be a major factor contributing to the evolution of drug resistance. However, the pattern and consequences of superinfection in HIV populations are far from fully understood. In this paper we study the implications of the fact...
متن کاملLow incidence of HIV-1 superinfection even after episodes of unsafe sexual behavior of homosexual men in the Amsterdam Cohort Studies on HIV Infection and AIDS.
BACKGROUND Human immunodeficiency virus type 1 (HIV-1) superinfection is infection of an HIV-1 seropositive individual with another HIV-1 strain. The rate at which HIV-1 superinfection occurs might be influenced by sexual behavior. Superinfection might be detected more often by analyzing longitudinal samples collected from time periods of unsafe sexual behavior. METHODS Envelope C2-C4 and gag...
متن کاملHIV-1 superinfection is associated with an accelerated viral load increase but has a limited impact on disease progression.
OBJECTIVE HIV-1 superinfection occurs frequently in high-risk populations, but its clinical consequences remain poorly characterized. We undertook this study to determine the impact of HIV-1 superinfection on disease progression. DESIGN/METHODS In the largest prospective cohort study of superinfection to date, we compared measures of HIV-1 progression in women who acquired superinfection with...
متن کاملFrequency and implications of HIV superinfection.
HIV superinfection occurs when an individual with HIV is infected with a new distinct HIV viral strain. Superinfection has been reported throughout the world, and studies have recorded incidence rates of 0-7·7% per year. Use of next-generation sequencing has improved detection of superinfection, which can be transmitted by injecting drug use and sexual intercourse. Superinfection might have inc...
