“I believe that the low effective rate of the vaccine this year is due to the mutations that the virus made in the processing of the vaccine itself,” said Anna Treague, nurse for Public Health. “That is at LEAST part of the reason that influenza cases are so widespread this year.”

The flu or influenza is a seasonal contagious respiratory disease that is caused by influenza viruses. The CDC says the dominant strain this year is H3N2, which tends to be more severe and causes more severe symptoms than most other strains.

Treague said that symptoms include fever, chills, headache, dry cough and aching of muscles and joints. They usually appear 1 to 3 days after being infected with most people recovering within a week.
