Thus, these data suggest that the immune responses to the first virus provided limited benefit against infection by a second virus of a different subtype. AIDS 2004;18:1513-20. Researcher Patricia Fultz of the University of Alabama has been able to infect chimps with a second HIV subtype as long as two years after the animals were infected with the Doctors say that even if both partners have HIV, you still need to use condoms during sex to prevent superinfection.
This is similar to what has been observed in a macaque model of superinfection with HIV-2, in which all 4 macaques challenged 2 weeks after initial infection became superinfected with the For all but 4 of the 21 cases, the V1 to V3 subtypes of the initial and the later viruses were indistinguishable. Additional genetic diversity is introduced as a result of recombination that may take place during HIV replication . HIV preferentially infects HIV‐specific CD4+ T cells.
Overbaugh. 2003. By the way, superinfection and reinfection mean the same thing. Another possibility is that the coinfecting strain of virus persists at a low level until viral evolution, drug treatment, or host immunity results in a fitness advantage for the minority strain

For example, in the case of subject QA013, reinfection occurred when plasma viral RNA was >105 copies/ml, and both the initial subtype D virus and the superinfecting subtype A virus could This "live attenuated" vaccine is the same kind Albert Sabin used in his polio vaccine: The weakened virus doesn't cause disease but primes the immune system to fight off the full-strength

However, the recent identification of several cases of HIV-1 reinfection suggests that the specific immune response generated for chronic HIV-1 infection may not be adequate to protect against infection by a Reactivation of human immunodeficiency virus type 2 in macaques after simian immunodeficiency virus SIVmac superinfection.

Now that Varrasso has embarked on a two-nucleoside combo, however, the couple is rethinking their sexual practices. The subtype of virus at the early time point was defined on the basis of envelope V1 to V3 sequences by using either the heteroduplex mobility assay or sequence analysis as Intermittent treatment in acute cases or for those just diagnosed may prolong their susceptibility to superinfection.

Subtypes C and C/A were detected at all six time points examined thereafter (n = 62, 6 to 17 clones/time point) except 1,440 days p.i., when 10/10 envelope clones obtained from These individuals had injection drug use as their risk factor and were coinfected with clades B and CRF-11.
