A man accused of exposing women to HIV admitted in a Clayton County courtroom Thursday that he has the virus and is taking medication for it.

Although he has HIV, Craig Lamar Davis testified he did not sleep with the woman at the center of the Clayton case. The woman claims he never told her he had the virus when they had sex in 2012.

Davis, a Stone Mountain resident who turns 43 Friday, admitted however to having sex with a Fulton County woman who accused him of infecting her. He said he told that woman, a mother of two, he had the virus at the time they were having sex. She went to the police only after learning he intended to go back to his wife.

Davis, a Stone Mountain resident who turns 43 today, is facing two counts of reckless HIV, a felony that could put him in prison for up to 20 years.

“I understand she’s hurt. I put her in a bad situation,” Davis said. “I wanted to go back to my wife.”

The Fulton woman, also testified Thursday, saying she went to the police to prevent Davis from harming other unsuspecting women. She grew emotional several times during her testimony, especially when she recounted finding out she had the virus after getting a routine physical. She will see Davis again when her case comes up in Fulton where Davis faces similar charges.

The woman in the Clayton case testified earlier this week she regularly gets tested for HIV. She said she does not have the virus. Davis said Thursday the Clayton woman, a real estate agent living in Union City, has stalked him.

“I do think that she has some serious issues,” Davis said. The case is being heard in Clayton because the woman in the case alleges they had sex at a home in Clayton County.

It’s unclear how Davis’ HIV admission will impact his defense since he has steadfastly held throughout the trial that HIV testing is inconclusive and therefore not reliable in detecting the virus. A California nonprofit that disputes the reliability of HIV testing is helping Davis in his court fight, which resumes Friday.
