Increased household exposure to respiratory pathogens in HIV exposed uninfected children due to maternal HIV

Abstract

Little is known about household exposures to respiratory pathogens in HIV-exposed uninfected children (HEU) in Indian families. This case series investigates the nasopharyngeal carriage of Streptococcus pneumoniae, Staphylococcus aureus, and respiratory viruses at multiple points in three mother child pairs: (1) an HIV-infected child and mother, (2) an HEU child and HIV-infected mother, and (3) an HIV-unexposed uninfected (HUU) child and mother. Nasopharyngeal carriage densities of Streptococcus pneumoniae and Staphylococcus aureus were higher in mothers and children living in HIV-affected households, regardless of the child's HIV status. Maternal HIV and ART status impact these household exposures.
