Here’s a headline for you — Worse than sex parasite: Sex parasite with virus. Yes, trichomonas (a sexually transmitted parasite that you’ve probably never been tested for), can actually harbor its own diseases. When infected with a virus — dubbed trichomonasvirus — trichomonas becomes even worse. Kill it, and it releases the virus, which causes inflammation and can actually lead to worse side-effects for infected people. (Via Charles Q. Choi)
