As usual H1N1 Disproportionately affected young people-9,635 confirmed nearly 60 percent influenzaRelated hospitalizations occurred in people between the ages of 18 and 64. Also, according to the CDC, people between the ages of 50 and 64 had the highest flu-related hospitalization rates this year compared to the last four seasons of flu.

These latest figures are from the June 6th issue of the CDC Journal. Weekly morbidity and mortality reports..

But things could have gotten worse.The predominant virus is due to previous widespread exposure to H1N1 and also this year Influenza vaccine, CDC said.

Authorities recommend inclusion of H1N1 virus next year Influenza vaccine In the same way.

“This year, vaccine This works fine, but millions of people are already exposed to the H1N1 virus, “said Dr. Michael Jhung, Head of Health Care at the US Centers for Disease Control and Prevention. Preventionof influenza Department, said HealthDayThe H1N1 flu has been epidemic since 2009, but “this is the first season since we saw it dominate,” he added.

The timing was also different. “The peak of the flu season was a little early,” Chung said. “Usually the highest activity is seen in January / February, but this season it happened about a month earlier.”

H1N1 was the most common flu strain, but “herd immunity” prevented H1N1 from becoming a pandemic again, Chung said.

In order for a virus to become a pandemic, it must be easily transmitted from person to person and have never been circulated so that people do not build immunity to the virus.

“The theory of herd immunity is that if you vaccinate a sufficient number of people, not everyone needs to be immune to stop the disease that spreads throughout the community,” he said. ..

For example, babies under the age of 6 months cannot be vaccinated against the flu, but if people around them are vaccinated, their chances of getting the flu are greatly reduced, Jhung said. I have.

Also, make up Of the current influenza vaccine vaccine In the last few years, Mr Chung said. “There is a very good preliminary estimate of 62% for vaccine efficacy,” he said.

This means that if you are vaccinated, your chances of getting the flu have been reduced by 62%. “In the last two years, the vaccine has been 47-49 percent effective,” said Jhung.

This year’s flu vaccine has protected people from H1N1 and other types of influenza, including H3N2 and a type of influenza B virus. Some formulations of the vaccine have additional strain B, which protects people from the four flu strains, Jhung said.

The CDC relies on hospital data to estimate adult mortality at the end of the flu season, and it’s too early to get those numbers, Jhung said. Adult influenza deaths in the United States typically range from 35,000 to 40,000 per year.

However, the agency has the latest records for children. So far this season, 96 children have died of the flu. According to the CDC, 348 children died of the flu when H1N1 first surfaced in 2009.

The best way to protect yourself from the flu is Influenza vaccination, CDC advises. The agency recommends that all people over the age of 6 months be vaccinated against the flu every year. This year, about 40% to 45% of those who need to get Influenza vaccination It was about the same as last year, Chung said.
