The U.N. health agency said in a fresh report that every day globally there were more than 1 million new cases of treatable sexually transmitted diseases (STD) or infections (STI). WHO found that there were more than 376 million new cases of chlamydia, gonorrhea, trichomoniasis and syphilis registered around the world in 2016 -- the latest year for which data is available. That is basically the same number as WHO reported in its previous study, based on data from 2012.
