HIV-1 Genetic Diversity in Northeastern Brazil: High Prevalence of Non-B Subtypes.

abstract：:HIV infection affects B cell function and is associated with increased immunoglobulin levels, including in HIV-infected pregnant women. It is unknown if maternal HIV infection affects immunoglobulins in their uninfected children. We investigated this using prospective longitudinal data from children born to HIV-infect...
