A 22-year-old Brazilian woman may have been infected with HIV after sharing manicure instruments with a cousin about a decade ago, according to a new study.

The woman discovered she was HIV-positive after getting tested to donate blood, according to FOX News.

She said she had not had unprotected sex or shared needles, behaviors that are often risk factors for HIV transmission, according to a report in the November edition of AIDS Research and Human Retroviruses.

She did, however, share manicure equipment with a cousin, who was later found to be HIV-positive.
