the point from the study is that someone may be recovering or recovered from being ill with the ebola virus, but still have infectious virus in their system.
that means, if the infectious virus is in a bodily fluid, that is transfered to another person, there is a possiblity that person could be infected.
so, if they are releasing the patient into the general population, instead of releasing him into an isolation type situation for several months, he could still be infectious.
as there is no mention of anything such as isolation occuring after he is released, did they consider that he might still carry infections viruses in his system, and might still be able to infect others?
seminal fluid is still infectious yes, but I assume you are not planning on having sex with the good doctor, nor will you be touching his eyes I think. His family will be educated about contact precautions.
Try not to live in fear over things you can’t control. Get out and enjoy life:)
