ST. LOUIS - Six weeks after someone with HIV said that dozens of students at a St. Louis high school might have been exposed to the virus, it remains unclear whether an outbreak has occurred.

Missouri health authorities say that preliminary October test results for St. Louis County show two new cases of HIV among people 24 and under.

It isn't clear whether those cases are even connected to Normandy High School, where students were tested voluntarily in late October. An infected person told county health officials that as many as 50 teens might have been exposed to the virus that causes AIDS.

The county plans a second round of HIV testing in January. Antibodies to the virus can take three to six months to appear. *
