Syphilis cases have increased the most in regions with the highest use of Facebook, officials tell the Telegraph. "There has been a fourfold increase in the number of syphilis cases, with more young women being affected," said a local public health chief. "Social networking sites are making it easier for people to meet for casual sex," he added. A Facebook spokesman urged people to take "precautions" and be careful when meeting up with someone they first encounter online.
