A new report from Centers for Disease Control and Prevention has found that between 2001 and 2006 gay male sex was the largest HIV transmission category in the U.S. and also the only one which recorded an increasing number of HIV/AIDS diagnoses.

The most affected are gay boys and men between the ages of 13 and 24 years, with minorities even more. The findings were released in this week's issue of the CDC journal Morbidity and Mortality Weekly Report. Other factors such as genital herpes could actually double a person’s risk for contracting HIV.

Also, The New York City Health Department’s Bureau of Epidemiology Services issued the results of a survey revealing that 40 percent of New Yorkers with multiple sex partners did not use a condom the last time they had sex. Also about 11 percent (610,000 adults) of them had multiple sex partners, a fact that increased their chance of contracting sexually transmitted infections.

Moreover, the city is considered the epicenter of the country’s AIDS crisis and where the number of herpes cases is above the national average. It's enough to mention that Bronx residents account for nearly a fourth of New York City's HIV infections and a third of AIDS deaths each year, according to a statement by the New York City Department of Health and Mental Hygiene.
