People Infected with HIV in New York City are about three times more than in any other part of the nation. The New York City Department of Health and Mental Hygiene released an estimated statistic on Wednesday through which they revealed that 72 of every 100,000 New Yorkers contracted HIV in 2006.

The national rate is only 23 per 100,000 and 4,800 of the people in New York got infected with the virus.

The HIV infected 33 million people all around the world and killed more than 25 million until now. The virus is spread in blood, semen and breast milk. The common ways to get infected are unprotected sex, shared needles and genetic transmission.

The Centers for Disease Control and Prevention has developed a new system to keep statistics on the people infected with the HIV virus. This new lab technology helps the health officials to see whether people got infected with the virus within five months.

 Health Commissioner Thomas Freidan said that "The populations that bear the greatest burden nationally -- blacks, for example, and men who have sex with men -- are highly represented in New York City. Because HIV is more prevalent within those groups, the risk of HIV infection per sexual contact is higher."

Thomas Freidan also stated that 36% of the gay and bisexual men in New York who had more than five sex partners in the last year didn’t use condoms every time. According to the investigations, these are the people more likely to get and to spread the HIV.
