A 22-year-old woman in Brazil
who tested positive for HIV
likely contracted the virus through the use of manicure instruments that she had shared with an HIV-infected cousin, according to a new report of her case.
The woman was diagnosed with HIV in 2013 when she donated blood. Doctors tried to rule out all other possible modes of transmission, said Luis Fernando de Macedo Brigido, of the Adolpho Lutz Institute in São Paulo, Brazil, who was one of the researchers who reported the case.
