The Waco-McLennan County Health District Thursday reported an increase in the number of HIV and syphilis cases in the county.
"It's an ongoing outbreak," Waco-McLennan County Public Health District infectious disease specialist Dr. Edward Farley Verner said Friday.
"We're just getting more new cases this year than we have in the past."
Since Jan. 1, 12 new cases of HIV have been diagnosed, 11 of them in sexually active men who are having sex with other men.
Since March 14, five primary and secondary cases of syphilis have been diagnosed, all of them involving men having sex with men.
"Most likely the HIV transmission and syphilis transmission that's happening is probably from someone who doesn't know they have it themselves," Verner said.
The health district is urging homosexually active men to be tested for HIV and syphilis.
