  • The H3N2 variant of the influenza virus has caused just over half of all new cases.
  • This year’s flu vaccine is about 44 percent effective against that strain.
  • But the CDC warns the flu season may linger for months and urges everyone to get an influenza virus.

The number of flu diseases caused by a more serious strain of the virus has risen recently.

In the last week for which numbers were available, the H3N2 variant of the influenza virus reported slightly more than half &#821

1; 54.1 percent of all new cases Centers for Disease Control and Prevention.

The H3 variant was the dominant virus seen in several regions a week ending February 22. They were Region 2, New Jersey and New York; Region 4, Alabama, Florida, Georgia, Kentucky, Mississippi, North Carolina, South Carolina and Tennessee; Region 6, Arkansas, Louisiana, New Mexico, Oklahoma and Texas; and Region 7, Iowa, Kansas, Missouri and Nebraska.

This year’s flu vaccine is more effective against H1N1 than it is against the H3N2 virus. about 62 percent compared to 44 percent.

“It seems that we are moving from an H1 wave to an H3 wave ,” Lynnette Brammer, leader of the CDC’s domestic influenza monitoring team, told Health Day News.

Thirty-three states and New York City showed high influenza plants in late February, the CDC reported.

About 20 out of 100 doctor visits were due to flu-like symptoms. It is about twice as high as would normally be expected this time of year.

Brammer told Bloomberg that the CDC has seen the higher prices since mid-November and it has not yet fallen.

“It doesn’t come down as you expect, but we’ve had seasons in recent years where flu-like illness was over the baseline for 20 weeks,” she said. “This season can be on the farther side of it.”

Since October 1, as many as 11.1 million people have visited a doctor because of flu symptoms and as many as 23.6 million people have had the flu. This has resulted in 252,000 to 302,000 hospital stays.

Between 16,400 and 26,700 people have died due to the flu since the flu season began. A total of 56 children have died due to the flu this season.

Brammer says this season can continue for several weeks or months, and she urges people who have not been vaccinated to get their shot.

“As long as the flu circulates and you have not been vaccinated, we recommend that you continue and be vaccinated,” she says.

“There is still a lot of flu to come.”
