Unfortunately it has no inhibitory effect against inﬂuenza B viruses which are important viruses causing mortality about every fourth year. Nervousness is the main side-effect noted in about 8% of persons receiving 200 mg amantadine per day but dosage 31 can be halved to avoid these problems and still maintain antiviral effects. A very similar molecule but with an extra methyl group attached (rimantadine) has equivalent clinical activity but causes rather fewer side-effects. Studies of the therapeutic use of amantadine in prisons, schools and universities throughout the world showed, perhaps surprisingly, that if the drug was given after infection but within 24–48 hours of the onset of symptoms these resolved more quickly and the number of days of incapacity was reduced.

Whitley Most virus infections run an asymptomatic course, or they are so mild that medical attention is not required. In many clinical cases an accurate aetiological diagnosis can be made solely on the basis of the clinical manifestations of the disease. Thus most cases of measles, varicella, zoster and mumps are diagnosed by the patient, his or her relatives, or by the family doctor.
Addition of protease inhibitors and nonnucleoside inhibitors adds further beneﬁts. These extra clinical beneﬁts are assumed to accrue partly because of avoidance of drug resistance. Furthermore, DNA polymerase enzymes have a higher ﬁdelity of reading and fewer transcription mistakes occur. However, although mutation rates may be 1000-fold less with herpesvirus than with an RNA virus, drug resistance does occur in immunosuppressed patients undergoing transplantation surgery or in AIDS patients where herpesviruses with mutations in the thymidine kinase gene allow the mutant to escape from the effects of aciclovir.
