Influenza viruses are constantly changing. It’s not possible to predict what this flu season will be like, and it’s not unusual for new flu viruses to appear each year. While flu spreads every year, the timing, severity and length of the season usually vary from one season to another. Commonly peaking in the United States between December and February, flu season can begin as early as October and last until as late as May.

The Center for Disease Control and Prevention recommends a yearly vaccine for everyone six months of age and older as a vital defense against contracting main flu viruses. However, there are additional ways to keep from getting it. Some everday preventative actions include staying away from sick people and washing your hands with soap and warm water for at least 20 seconds to reduce the spread of germs. Also, if you are sick with flu, stay home from work or school to prevent spreading flu to others.

Vaccination is especially important for people at high risk for serious flu complications and those close to them. Children between six months and eight years of age may need to doses of flu vaccine to be fully protected, according to the CDC. Children younger than six months are at a higher risk of serious flu complications, but are too young to receive vaccination. This means safeguarding them from germs is especially important. Those who care for or live with an infant younger than six months should get vaccinated to aid in defending them from flu as well.

The enterovirus, EV-D68, however, cannot be defended against by receiving a flu shot. A few days ago, North Carolina Health and Human Services released information that six cases of EV-D68 have been confirmed in North Carolina. Since the flu shot cannot prevent this new enterovirus from spreading, there is some important information to know.

EV-D68 is spread via droplets, according to Vidant Beaufort Infection Control Nurse Billie Whitfield. This means the virus can rest on surfaces so it is important to keep frequently touched surfaces — like countertops, toys, door knobs, remotes, grocery store cart handles and more — disinfected. Being within three feet of someone who is sick can greatly increase the chance of getting sick.

This flu season, be extra careful. It is important to stick to the same guidelines as any other respiratory virus.
