The risk of becoming superinfected (contracting another strain[HIV strain] Any subgroup of the HIV species. Because HIV mutates very easily, there are many different strains (and may be multiple strains within a single person). of hiv to the one you have already) may be as high in the community as the risk of contracting hiv, according to a paper released in february.
Superinfection can be difficult to detect, claim the writers, and is undoubtedly underdiagnosed.
However, many superinfections are unlikely to be clinically relevant.
Studies show wide variations in the incidence of superinfection, from no detected cases to rates close to those of HIV infections in the background population. This is due to wide variation in several factors including laboratory methods, sample timing and frequency, HIV-1One of two distinct HIV species, HIV-1 is the predominant type in Australia and around the world. subtype[HIV subtype or clade] A genetically distinct subtype of HIV within a defined HIV group. Group M has nine known subtypes -- A, B, C, D, F, G, H, J and K., ongoing risk behaviour and ART use.
Seroconcordant partners with no differences in HIV resistanceHIV which has mutated and is less susceptible to the effects of one or more anti-HIV drugs is said to be resistant. pattern can rest assured, the writers advise, unless one individual develops new, significant resistance. Those with an unexpected, unexplained jump in viral loadA measurement of the quantity of HIV RNA in the blood. Viral load blood test results are expressed as the number of copies (of HIV) per milliliter of blood plasma. levels should undergo repeat resistance testing if they are at risk of superinfection.
