Tennessee Department of Health officials have noted a steady increase in influenza activity in Tennessee and warn the flu season could be severe. The Department of Health urges everyone to protect themselves and their families by getting a flu shot now.“Early indications suggest this could be a more severe flu season than we have had for some time,” said TDH Commissioner John Dreyzehner, MD. “Vaccination is likely to reduce the risk of severe illness, even if not all strains are matched to the vaccine throughout the season. Because a flu vaccine is still the best protection, get it now if you have not done so.”While vaccination is a much better preventive measure than waiting to be sick and getting treatment, early treatment is essential to preventing more severe illness.
