Washington's flu season is ramping up and, already, three people have died from the virus this season.

This is the standard timeline for the flu, which presents in Washington about this time each year.

More than 240 people died in each of the past three flu seasons... in Washington state.

The number rarely reached 100 before 2016.

Flu season changes year to year, but the peak in the last three years was toward the beginning of February.

The Department of Health says now is a good time to get a flu shot, if you haven't already, before the flu spreads further.

"Flu activity really is unpredictable, and it can ramp up and die down at different times each year," says Danielle Koenig, a health promotion supervisor for the state Department of Health.

2018 was a big year for the Influenza A virus, while the year before had a mix of influenza A and B strains.

It's too early to know what strain is predominant in Washington this year, but the U.S. vaccine fights against three or four of the most common ones.
