[Treatments

There is very little treatment for viral infections other than for herpes viruses which are treated with an anti-viral drug Acyclovir. Rest is important and peace and quiet to allow the body to fight the infection. Other medication is given to treat specific areas affected e.g. anti-convulsants for seizures, antibiotics to prevent other (bacterial) infections, sedatives to keep the person calm. If the inflammation is serious, heavy sedation may be given and the person put on a life support machine. This takes over all body functions allowing the body to rest totally and concentrate on fighting the infection.]
