The federal Centers for Disease Control and Prevention conducted various studies to determine what surfaces were contaminated with germs. The study found that common household items like door knobs and remote controls can be place for germs to linger for two days or longer. The transmittal of germs to objects like these often times spread viruses and germs throughout a household. The study also examined the surfaces of toys in five pediatricians offices in Fairfax, Virginia. The study revealed that seventeen to thirty percent of the toys study were contaminated with germs. These findings show the prevalence of germs and the problems in preventing the spread of viruses and the flu in settings like the home, dorm rooms, pediatrician offices, and college dorm.
