– More than 11,200 patients in the United States were hospitalized with the flu in the past week, the highest rate in the same time period since 2010, according to data released Monday by the Centers for Disease Control and Prevention (CDC). from USA
Seasonal flu activity is elevated across the country, the CDC said.
Five pediatric deaths associated with influenza were reported in the week ending November 19. According to the CDC, a total of 12 pediatric deaths from influenza have been reported so far this season.
The CDC estimates that, so far this season, there have been at least 6.2 million cases of flu, 53,000 hospitalizations, and 2,900 deaths from flu.
Of the influenza A viruses detected and subtyped this season, 78 percent have been influenza A (H3N2) and 22 percent have been influenza A (H1N1), according to the CDC.
“We’ve seen, in some regions, RSV numbers start to trend down. Flu numbers continue to rise. And we’re concerned that after the holiday gatherings, a lot of people gather, that we might see increases in numbers.” cases of COVID-19 as well,” said CDC Director Rochelle Walensky.
The US’s top infectious disease expert, Anthony S. Fauci, warned that RSV could become a public health emergency in the United States.
“In fact, in some regions of the country, we’re seeing the pediatric hospital system on the verge of being almost overwhelmed,” Fauci told CBS News on Sunday.
The CDC said that an annual flu shot is the best way to protect yourself against the flu. Vaccination helps prevent infection and can also prevent serious outcomes.
The CDC recommends that everyone 6 months and older get a flu shot annually.
For half a century, scientists have been trying to develop a vaccine that protects against the most dangerous flu viruses.
Now, researchers at the University of Pennsylvania are investigating experimental flu vaccine targets to target 20 influenza viruses in a single vaccine.
Seasonal influenza vaccines offer little protection against pandemic influenza virus strains. It is difficult to create effective pre-pandemic vaccines because it is not clear which subtype of influenza virus will cause the next pandemic, according to a paper published by the researchers in the journal Science.
Researchers developed a nucleoside-modified messenger RNA (mRNA) lipid nanoparticle vaccine that encodes hemagglutinin antigens from all 20 known influenza A virus subtypes and influenza B virus lineages.
This multivalent vaccine elicited high levels of cross-reactive and subtype-specific antibodies in mice and ferrets that reacted to all 20 encoded antigens, according to the research. ■
