What does it mean when someone says they have the “flu”? This usually means they have a “cold” or upper respiratory infection with runny nose, cough, and maybe a low-grade fever. Sometimes people say they have the “stomach flu”, and this usually means that they have an intestinal virus causing nausea and/or diarrhea. However, to healthcare workers, “flu” refers to illness caused by one of two specific viruses – Influenza A or Influenza B.
Influenza A and B viruses cause widespread infections called epidemics each fall and winter in the
Symptoms of the flu are many and can include high fever, headache, sore throat, extreme tiredness, runny nose, dry cough, muscle aches, and sometimes vomiting and diarrhea. Complications can include pneumonia, sinusitis, ear infections, dehydration and worsening of the chronic conditions mentioned above.
You can get the flu by touching something infected by another’s cough or sneeze, and then touching your nose or mouth. It’s possible to spread the flu up to one day before you even feel sick yourself!
You can easily dramatically reduce your chances of getting this deadly disease by getting a flu shot (or the inhaled version called FluMist). The flu shot is approved for almost anyone over 6 months of age, and is recommended for healthy people as well as those with chronic medical conditions. There are only a few people who should not receive the flu shot – Be sure to ask your primary care provider if it’s OK for you to get a flu shot. (The shot form is even OK during pregnancy!)
Don’t let it be open season on you! Wash your hands frequently, cover your sneeze and cough, and ask your primary care provider about a flu vaccine! Flu vaccinations are available now, but can be very helpful as late as December and January. Don’t wait to protect yourself!
