The number of syphilis cases has increased dramatically in recent years in central New York.
It used to be that when there was an outbreak of syphilis in New York state, the state Department of Health would find people infected in a particular school or neighborhood.
"But now the social networks are different. People meet though the Internet. If they’re looking for sexual partners, and if they throw that net wide enough, they’re going to find them,” said Dan Casler, the head of the state health department’s communicable disease program.
