The flu season in the United States has reportedly peaked and is showing signs of slowing down, but parents should keep their guards up, warned the Centers for Disease Control and Prevention.
There is Influenza A, and there is Influenza B. According to the CDC, more "B" cases are being reported lately and they can be more severe for younger children.
The study concluded the findings showed a need to increase attention to Flu B which typically gets overshadowed each season by Flu A. However, the researchers also made it clear the results of the study were consistent with the view that any form influenza rarely kills on its own without a coinfection or secondary cause such as a weakened immune system.
Which means, even if you already had Influenza A virus this year, the antibodies you formed will not provide protection from the B virus.
So far this year, 246,766 people have tested positive for the flu, with 78 percent of the 26,694 total hospitalizations reported attributed to the influenza A virus. "Unfortunately, we don't know what the influenza B wave will look like", said CDC spokeswoman Kristen Nordlund.
Both Flu A and Flu B activity has massively decreased compared to January and February. Experts recommend everyone who is unvaccinated get a flu shot while strains are still circulating.
"Well, you can't really say, this strain causes this and this other strain causes other symptom", said Tammy Koonce, a nurse with the Guilford County Health Department, "It seems to be flu symptoms are just flu symptoms". Chalkley says, "Some of our  deaths have been attributable to Influenza A while others have been attributable to Influenza B".
Because of influenza B, the flu season is now expected to extend into late April or early May. But while we have weathered yet another year against a microscopic enemy which constantly threatens to evolve beyond our ability to inhibit with vaccination, the CDC says we are not out of the woods just yet.
Doctor say the best method of defense against the flue is practicing good hygiene and getting the flu shot as chances of severity and the length of the flu sticking around decrease with the shot.
"This was a rough flu season".
