STD That Causes Blindness is on the Rise


Developed countries are seeing more cases of ocular syphilis.

Increasing numbers of people in industrialized countries are at risk from permanent eye damage to their vision as a result of the sexually transmitted disease syphilis, Newsweek reports.

An international team of researchers warned about the threat in a study published in the journal Scientific Reports.

Syphilis rates have been on the rise worldwide in recent years. In the United States, for example, numbers have more than doubled from 2.1 cases per 100,000 people in 2000 to 7.5 cases per 100,000 in 2015, according to the Centers for Disease Control and Prevention (CDC).
