The second wave of flu viruses is happening now

(KWCH) – The flu season is drawing to a close, but according to the latest Centers for Disease Control report, B viruses are reported more frequently than the A strain, which has been dominant recently

In the week ending March 17, almost 58 percent of all confirmed cases of influenza were caused by the B strain.

A CDC spokeswoman says B-strain flu viruses tend to be harder for younger children.

Experts say it's possible that those who already have the flu will get sick later in the season.

They recommend anyone who is not vaccinated to receive a flu shot while strains are still circulating.

Karen Bolly, Director of Infection Prevention for Via Christi says, flu season usually lasts from October or November to May.

Bolly says the best method of defending against the chimney is practicing good sanitation and the flu shot as chances of heaviness and length of flu flu

"We are tracking all of our viruses and we definitely have an increase in influenza this year -A and influenza B virus, as well as (what) many states across the country reported, "says Bolly.

She says there has been a steady decline in influenza A in recent months.

"But we still see how the influenza B virus still lingers a bit," says Bolly. "We've seen a handful of them a day, so it's not uncommon to see the Influenza B trail a little longer based on the flu season that we had this year."

Still, the numbers are not what they are at the height of the flu season at or just after Christmas. However, some who were ill earlier in the year go back to the doctor with a different strain.

"Some of the patients we see actually had influenza A and now they come back with influenza B," Bolly says. "The virus strands change a bit and they mutate a bit throughout the season, so sometimes you see one or more just lingering a bit."

Although doctors are seeing more cases of Influenza B at the beginning of spring, Bolly says there is no need for patients who had the flu shot this year to get another one.

While warmer months typically indicate the end approaching for flu season, Bolly says there is no way to tell when to expect an accurate cutoff.
