Flu Season

The 2019-2020 flu season is in full swing. Are you safe from the flu this year? Did you get your flu vaccine?

According to the Centers for Disease Control and Prevention: Between 3% and 11% of the US population get symptomatic flu every year. This is an average of 8%. Of this number:
  •   Children under the age of 17 years are at greatest risk to be ill from the flu
  •   Adults 65 years and older are at the least risk to be ill from the flu

Every year the CDC uses advancements in knowledge of influenza vaccines to select the viruses for the seasonal flu vaccine. This is due in part to the influenza virus’ ability to constantly change.
There are only four types of influenza viruses:
  •   Influenza A:
     o   Cause of annual seasonal epidemics
     o   There are potentially 198 different Influenza A subtypes, 131 have been detected
     o   Only influenza virus to cause flu pandemics
           Occur when new and very different virus mutations emerge and infects people and spreads efficiently
  •   Influenza B:
     o   Cause annual seasonal epidemics
  •   Influenza C:
     o   Cause mild illness
     o   Does not cause epidemics
  •   Influenza D:
     o   Affects cattle not humans

Statistics from the 2019-2020 flu season include (ending November 30, 2019):
  •   2.7/1000 cases have required hospitalization (like other recent seasons)
  •   There is a 4.8% mortality rate down from 6.4%
  •   6 pediatric deaths have been reported
  •   3.5% of healthcare provider visits were for the flu
     o   This is higher than the national baseline of 2.4%

Protecting yourself and patients from getting the flu starts with following a few basic tenets of infection prevention:
  •   Hand hygiene
  •   Cough hygiene (cough into a tissue or your upper arm not in your hands)
  •   Get vaccinated, everyone over the age of 6 months should be vaccinated
     o   169.1 million doses have been distributed
  •   Avoid close contact
  •   Stay home when you are sick
  •   Avoid touching your nose, mouth, and eyes
  •   Clean and disinfect frequently touched surfaces

What if you get the flu?
  •   If you are healthy, stay home and avoid contact with others
  •   If you are very sick or in a high-risk group:
     o   Go to your healthcare provider within 48 hours of start of symptoms
     o   Get an antiviral medication
           Will shorten and make symptoms milder
           Will help prevent serious flu complications like pneumonia
     o   Stay home except to go to your healthcare provider

We still have a long way to go this flu season. Influenza prevention should be a priority. Get vaccinated, cover coughs, and stay home if you are sick. Pretty simple recommendations; but they can do a lot to keep you and others from getting sick.
