Roseola prevention: Roseola is a viral infection that is most contagious while the infected person is having the fever. It is generally not a dangerous illness, and people who have had it will continue to shed the virus intermittently for the rest of their life. Since it is spread through the saliva, risk of transmission can be decreased by waiting until contacts are rash free, and not sharing cups, etc.
Dr. James Ferguson

More or less: Since this virus is contagious before the fever or rash occurs great efforts to exclude the kid from contact with others is not very helpful. They can return to day care or school 24-48 hrs after the fever is gone even if some rash persists. Routine efforts to limit exposure to saliva should continue as it would before the illness.
