What percentage of MS doctors routinely check for latent viral reactivation in addition to bacterial infections when assessing patients whose symptoms are progressing? What factors influence doctors to perform this check or not to perform it?

Our doctors are quick to rule out bacterial infections as cause of PIRA. No one is checking for EBV, CMV, HHv6 because we progress without symptoms. Grass roots - many of us have a positive EBV early antigen. Test and respond to antivirals. They are the difference between me in a wheelchair and me without assistive devices. As we age, even the typical population has trouble with latent virus. I happen to be AA for that severity gene so perhaps this is why. But it’s a tragedy that neuros and doctors are not checking for this with increasing balance, cognitive and leg weakness difficulties.
