I am not, I am far better educated on the subject than you are to know that there is no "completely cured", there is limited medical research on latent Ebola but this area will be better understood by scientists in the coming years.

You should read up on virus latency, there are many viruses apart from ebola that can be reactivated and transmitted sexually like HIV, or hepatitis. Especially when the patient is in an immunosuppressed state, it is possible for the virus to lay dormant in a part of the body which the immune system cannot reach.

Most importantly, patients are not infectious until they develop symptoms like fever, muscle pain, headache and sore throat. And even then, the risk of contagion involves coming into contact with an infected carrier's bodily fluids like mucus, blood or semen. That is why they are tracking down only the people nurse Cafferkey met after she reported sickness, not Samantha Cameron or anybody else she met over the whole year after she was discharged. Not all the people who met her need vaccination or quarantine because there was low or no risk of bodily fluid exchange. Stop fearmongering like this is some 28 Days Later scenario you watched on TV.
