CDC: Rare infection may surface in U.S.

The U.S. Centers for Disease Control and Prevention is cautioning medical professionals to be on alert for a new sexually transmitted disease in America. Doctors and clinics everywhere are getting ready to identify and treat both gay and bisexual men that may be infected with Lymphogranuloma venereum, or LGV.
LGV had been seen in Europe very rarely until last year when numbers of those infected jumped to a large amount. This type of STD is caused by chlamydia, and some of its common effects are genital ulcers, enlargened lymph glands, flu-like symptoms, and more currently, gastrointestinal bleeding.
It is believed that LGV is passed through high-risk sexual behavior. It can be treated by three weeks of antibiotic use, but it is easily misdiagnosed. It is unknown how many cases of LGV have existed or currently do exist in the nation today.
