Zika and Ebola are sexually transmittable

It's difficult to quantify, how many of these viruses are sexually transmittable, but it is already clear that Zika and Ebola are. Marburg (which is similar to Ebola), Lassa fever, and mumps may be, too. Scientifically, we're now in a place where we can't conclusively say what is sexually transmissible and what is not.
