The sore throat from my acute viral infection (that later led to ME/CFS) never went away in my case, and my throat has been continually sore for the 12 years I have had this virus. The sore throat was the first symptom my virus produced (but within weeks the virus also started spreading to other organs like the stomach, giving me chronic stomach aches, and then spread to the intestines).
Up to two years after my acute viral throat infection, I was still infecting people with my virus, whenever I was in close social contact with anyone (eg: sharing a meal). So clearly my chronic sore throat was not only inflamed, but also shedding infectious viral particles.
Whether my sore throat is still shedding viral particles 12 year on I don't know; I would only find out if I spent some time in close social contact with a new acquaintance; all my current friends and family have my virus, so they are already infected.
My original sore throat was herpangina-type sore throat. A
herpangina sore throat is one in which there are inflamed red tissues specifically in the area at the back of the soft palette (on the palatoglossal arch — the arch the uvula hangs down from). Herpangina is usually caused by enteroviruses such as coxsackievirus B.
Interestingly, during the acute infection period of my herpangina sore throat, the red inflamed tissue was found just on one side of my palatoglossal arch, near where this arch meets the tongue. After many months, this redness in my throat very gradually went away, and after some time, a
crimson crescent appeared in roughly the same place as the original red herpangina inflammation.
You can see a picture I took of the crimson crescent in my throat in
this post.
I think it is very interesting that crimson crescents appear to be the long term sequelae of the original herpangina sore throat. Sore throats mark the beginning of many a case of ME/CFS. The crimson crescents might conceivably be an area of the mouth where there is a low level enterovirus infection deriving from the original virus.
Some have suggested the long term presence of crimson crescents on the soft palette of ME/CFS patients may be a diagnostic sign for ME/CFS.
