Covid-19 means one year without the flu. It is not all good news


As the autumn fades Last winter, a number of infectious disease researchers diverted their attention from the Kovid-1p epidemic and began to return to something more familiar. It was at this time of year that they would typically look at their numbers to see how bad the influenza, seasonal flu outbreak would be, and to determine how effective the vaccine that year was with the proton respiratory virus.

The answer was: bupkis. Very easily someone was sick or dying of the flu. A year ago, during the 2019-20 flu season – mainly in the fall and winter, aking in December, January and February, 18 million people in the United States saw a doctor for their symptoms and 400,000 people had to be hospitalized. In all, 32,000 people died. But this season, the lawsuits Barely four digits have passed. “There is always a vaccine season and a flu season. We’re used to working on that pattern, and the pattern is broken, “said Emily Martin, an epidemiologist at the University of Michigan School of Public Health, partner for the Flu-Monitoring Network for Disease Mixing and Prevention. “Influenza didn’t have to be controlled. That would have been a disaster. But at the same time, it’s a strange year.”

Strange indeed. And it’s not just the flu. Case numbers primarily affect children in the case of respiratory syncytial viruses and there is also a season-to-rhythm like influenza, which is bottled. A Paper Published last week, the missing-action list also includes antivirus D68, a polio-like pediatric disease probably the culprit behind acute flaxseed mellitus. Viruses and AFM come and go almost every other year cycle, and the last episode in North America was 2018-2020, they, too, miss their expression.

The Why This is not actually a mystery. Probably. Probably, wearing all the masks, physical distance, hand washing and other “non-pharmaceutical interventions” that everyone is okay with, Almost Everyone tried to stop the spread of Kovid-19 Leave the kibbutz too On those other viruses. It’s not just a guess, but it’s a good one.

Being a mystery How And what’s next. The answers can help scientists learn more about how they infect other diseases and how to stop them. The mechanics of why this NPI crushed at least three other respiratory viruses while continuing Covid-19 is not clear. Even less clear is what it means for a year without flu for the next winter of the year and for the winter after that. Influenza kills 12,000 to 61,000 people anywhere in the United States each year and is seen as one, spending 11 11 billion on the economy each year Guess. For decades, until centuries, people have simply taken this risk. But if it is seen that it is almost completely preventable, then what is the will of the people to bear the risk change?

When the epidemic occurs A virus hit her Evolutionary groove. The virus that caused Covid-19 is called SARS-Cov-2, and when it descended in late 2019, no human immune system had ever seen it before. No one had any defense. The respiratory-pathogen in people who have no symptoms that can infect them sets them apart from most cousins ​​- it’s different enough to take advantage of human social interaction and go global.

But to turn the virus into an epidemic, such as the smallest situation or genetic twist, is a disease version of a band that fills the arena, small clubs don’t take too much to confine any disease to the playing field. “The Covid-19 control system – wearing a mask and social distance – really works and they work really well for other respiratory pathogens as well,” said Rachel Baker, an epidemiologist at Princeton University. The main difference is probably that other diseases have been playing jigs for thousands of years and people are slightly hurt by their attitudes. Even the flu, with its famous mutable genome that requires a new vaccine every year, leaves behind some level of resistance on the scale of the population. “We have a large population with immunodeficiency disease, we have vaccines, and most people over the age of 2 have RSV,” said Baker. “That’s why you don’t have any seasonal epidemics.”
