Influenza spreads readily from person to person in schools, workplaces and homes. Everyone 6 months of age and older should get an annual flu vaccine to prevent sickness, healthcare visits, hospitalizations, and deaths from influenza.

Protection lasts throughout the flu season, which usually peaks in January or February and continues into the spring. Some children and adults may be eligible to receive nasal spray flu vaccine.

People with egg allergy may also be eligible to receive flu vaccine. Talk with your healthcare provider or pharmacist about which flu vaccine is recommended for you.

2017-18 weekly flu surveillance reports

During the week ending May 19, 2018:

  • The percent of visits to King County emergency departments (ED) for influenza-like illness (ILI) is below baseline levels and comparable to the 5-year average for this time of year.
  • There was 1 new long-term care facility outbreak but no new influenza related deaths reported. Sixty-six long-term care facility outbreaks and 44 influenza related deaths have been reported this season - both are above the 5-year average.
  • The 2017-18 flu season had two distinct “waves,” with the first increase in ED ILI visits beginning at the end of 2017 and lasting approximately 12 weeks, and a second increase with smaller magnitude beginning at the end of February. The percent of ED ILI visits is currently at or below baseline levels among all individual age groups, as well as among all ages combined.
