Recentlyinadultsprimaryinfectionswereobserved,too.Aftertheprimaryinfectionsomeviruses establishalatentstateintheirhostcells(mostlyganglialcells).ThevirusDNAisintegratedinto thegenomeofthehostcell,whereitremainsuntiltheinfectedpersondies.Afterstimulationofthe hostcell,recurrentinfectionoccurs,whichiscalledanexacerbation,whenclinicalsymtomsappear.
