The Centers for Disease Control and Prevention is testing for the gonorrheritis-like strain of syphilis in a large population of adults, the first time the virus has been tested in this way.
The CDC says the tests will help researchers better understand the virus’ transmission routes, including to people who are sexually active.
Symptoms of gonorrheroids can include fever, chills, fatigue, muscle aches and joint pain.
Symptoms can last up to seven days.
The first tests will be done in the United States in late May.

The testing is the first step in testing the virus in more than a million people.
The United States is one of the top hotspots for gonorrhoea and syphilis, and the CDC has warned that people in the U.S. are increasingly vulnerable to infections because of the spread of gonorhal disease and syphilitic meningitis.
