The CDC reported a rare HIV transmission by sexual contact between two females.

The center received the report from the Houston Department of Health on Aug. 2012.

The case was investigated and laboratory testing confirmed the woman who was recently diagnosed with HIV received the virus from her partner, who currently has the disease and stopped receiving treatment in 2010. 

The couple revealed having unprotected sex.

The 46-year-old woman who just acquired HIV reported that she had three female sexual partners in the past five years. 

On April 10, days after donating plasma, she went to an emergency room with a sore throat, fever, vomiting, muscle cramps and frequent diarrhea.

She initially was tested for HIV and the results returned negative but 18 days later, after another attempt to donate,  the results came back positive.

The virus can take two weeks to six month to develop, the process is called seroconversion, and its when a person begins to produce the antibodies an HIV test is looking for. The CDC recommends those with possible exposure to the disease retest 3 months after infection. 

Female to female transmission is extremely rare, but CDC recommends everyone who sexually active practice safe sex by using prophylactics.
