Coughing. Fever. Runny nose. Upset stomach. Diarrhea. You probably know someone with these symptoms right now. This is the time of year when reports of influenza, norovirus and other viral and foodborne illnesses begin to pour into the Johnson County Department of Health and Environment. The best way to prevent these germs from making their way to you is frequent handwashing. Wash hands with soap and water after using the bathroom, changing a diaper and always before eating, preparing or handling food. Alcohol-based sanitizers should be used if soap and water are not available.
