This Year’s Flu Season

The 2017 flu season has peaked and is finally winding down.
The 2017 flu season has peaked and is finally winding down.

Breaking News: Flu season has peaked, and is winding down. (see below)

While flu season typically peaks in February, it is very important to understand that there are few things that are typical about the flu.

Since 1982, while we have been twice as likely to see a flu activity peak in February than other winter months, we have been just as likely to get that peak in December, January, or March. That makes it important to get your flu vaccine as soon as you can.

You really never know if it is going to be an early, average, or late flu season.

Flu Facts

While there will likely be some surprises this flu season – there always are – there are some things that you can unfortunately count on.

Among these flu facts include that:

  • there have been 1,482 pediatric flu deaths since the 2003-04 flu season, including 89 flu deaths last year
  • about 113 kids die of the flu each year – most of them unvaccinated
  • antiviral flu medicines, such as Tamiflu, while recommended to treat high-risk people, including kids under 2 to 5 years of age, have very modest benefits at best (they don’t do all that much, are expensive, don’t taste good, and can have side effects, etc.)
  • a flu vaccine is the best way to decrease your child’s chances of getting the flu

And even in a mild flu season, a lot of kids get sick with the flu.

This Year’s Flu Season

When does flu season start?

In general, flu season starts when you begin to see people around you with signs and symptoms of the flu, including fever, cough, sore throat, runny or stuffy nose, muscle or body aches, headaches, and fatigue, etc.

To be more accurate, you can also look at reports for flu activity in your area, especially the weekly reports from the CDC.

Those flu reports can also help you determine when flu season ends.

As of late-April, the CDC is reporting that “flu activity continues to decrease in the United States.”

The CDC has also recently reported that:

  • this year’s flu vaccine reduces “the risk for influenza-associated medical visits by approximately half”
  • influenza A (H3N2) viruses, a component of this year’s flu vaccine, predominated early in this year’s flu season, which could be a sign of a severe flu season. In general, “H3N2-predominant seasons have been associated with more severe illness and higher mortality, especially in older people and young children…”
  • Is it a match? – “…antigenic and/or genetic characterization shows that the majority of the tested viruses remain similar to the recommended components of the 2016-2017 Northern Hemisphere vaccines.”
  • As often happens on the downside of a flu season peak, we are starting to see more and more influenza B each week
  • There are reports of a new avian influenza A(H7N9) epidemic in China. Although deadly, there is fortunately no reports of sustained human-to-human transmission of this flu virus strain that is usually associated with poultry exposure.
  • Next year’s flu vaccine won’t be changing much, except that “The  A(H1N1)pdm09  virus  has  been  updated  compared  to  the  virus recommended  for  northern  hemisphere  2016-2017  influenza  season.”
  • only 3 states (down from 7), including Connecticut, New Hampshire, and New York, are still reporting widespread flu activity (the highest level)
  • only 8 states (down from 11), including Alaska, Arizona, Maine, Massachusetts, New Jersey, Ohio, Rhode Island, and South Carolina are still reporting regional flu activity
  • 20 states (up from 19), California, Delaware, Florida, Iowa, Kansas, Louisiana, Maryland, Michigan, Minnesota, Missouri, Montana, New Mexico, North Dakota, Oklahoma, Pennsylvania, Tennessee, Texas, Washington, West Virginia, and Wisconsin, and Puerto Rico are now reporting local flu activity
  • 19 states (up from 13), including Alabama, Arkansas, Colorado, Georgia, Hawaii, Idaho, Illinois, Indiana, Kentucky, Mississippi, Nebraska, Nevada, North Carolina, Oregon, South Dakota, Utah, Vermont, Virginia and Wyoming, are now reporting sporadic flu activity
  • there have been 89 pediatric deaths this flu season, including reports of 7 new deaths this week

Have you and your family gotten been vaccinated and protected against the flu yet?

“Anyone who has not gotten vaccinated yet this season should get vaccinated now.”

CDC Influenza Situation Update

If not, this is still a good time to get a flu vaccine.
