Second wave of flu virus happening now — CDC

The flu season had been dominated by the A-strain virus, but now the B-strain appears to be taking precedence, making up nearly 58 percent of the cases reported in the last few days, WFAA-TV reported. "Although the initial report of 36 percent overall efficacy for this year's vaccine in the United States that has been reported by our colleagues at the U.S. Centers for Disease Control and Prevention is better than some might have predicted, there is still clearly significant room for improvement".

While the flu numbers have dropped significantly since February, the CDC announced to expect another flu wave, particularly the B-strain that affects children in particular.

This is because people can get sick from both types of influenza during one season.

The flu remains considered widespread across ME, but the decrease in numbers may indicate the spread of the virus continues to slow.

In an update, the CDC says that reports of the influenza A virus are on the decline while reports of the influenza B virus were more prevalent. Experts recommend everyone who is unvaccinated get a flu shot while strains are still circulating.

"We know that illness associated with influenza B can be just as severe as illness associated with influenza A", Nordlund told CNN. "It's not necessarily so uncommon, but we just want to make sure people are aware that flu season is not over so you still need to remain vigilant when it comes to healthy behavioral habits".

Meanwhile, the CDC's map shows widespread flu activity is still occurring this spring in 17 states, including Wisconsin.

At this time, the influenza A strain had accounted for 75 percent of all cases. This is a reversal of the trend in the cumulative data of the CDC since October 1, 2017, with 75.6 percent of specimens testing as influenza A strains and only 24.4 percent as influenza B strains. You can catch it again.

Doctors' offices are preparing for flu season to last longer than normal and could see patients until the end of May and possibly even into June.
