As the disease has been so widespread in Washington and Montana, additional preventive measures should be considered by everyone. The most important way in preventing flu is to be vaccinated every year. Since it is a communicable disease staying away from people who are infected is recommended. Everyone must cover their mouth when sneezing or coughing, and washing hands regularly should be done.
