Communicable Disease

Handwashing is our first line of defense against germs

Studies show that children who wash their hands at least 4 times a day experience 24% fewer sick days from cold and flu. An FDA study reveals that proper handwashing can stop 1/2 of all foodborne illness such as ecoli and salmonella. The CDC released a report showing that handwashing nearly halved the incidence of pneumonia-related infections in children under 5 years old.
