such as The same virus of the respiratory systemRSV, otherwise known as RSV, continues to rise across the United States, with experts warning that people can become infected more than once.

“A person can get RSV more than once in a lifetime,” Dr. Aaron Glatt, chief of infectious diseases at Mount Sinai South Nassau Hospital in Long Island, New York, told Fox News Digital this week.

A second infection cannot occur immediately after a recent infection. However, it can infect a person more than once in the same season, especially Children with immune problems And seniors, Glatt said.

The American Academy of Pediatrics urged the Biden administration to declare an emergency over the ‘unprecedented’ RSV surge.

“Since RSV-NET began collecting children’s data in October 2018, RSV hospitalizations have been higher each week than in the previous four seasons,” a spokesperson for the Centers for Disease Control and Prevention (CDC) told Fox News Digital.

RSV-NET reports on surveillance of children and adults younger than 18 years of age with recent laboratory-confirmed and confirmed RSV-associated infection.

“This time is unusual because we don’t usually see this level of hospitalizations in October and November,” a CDC spokesperson said.

Even compared to the fall of 2021, when RSV prevalence was abnormal, it is now higher.

Earlier, the surprising increase of RSV concerned hospitals, medical centers

Glatt, a spokeswoman for the Infectious Diseases Society of America, added: “Certainly, RSV appears normally in the winter, so the weather plays a role and it’s on it.”

But you can get RSV no matter where it’s found, in any weather — even if it’s a winter illness, of course.

Why are we seeing so many cases?

“Prior to 2020, seasonal patterns of RSV in the United States were very consistent,” the CDC said on its website.

“However, the transmission of RSV and other common respiratory viruses has been hampered since its inception. The covid-19 pandemic In early 2020,” the agency added.

A CDC spokesperson told Fox News Digital, “CDC is now publishing weekly hospitalization rates for laboratory-confirmed RSV hospitalizations through the RSV-NET surveillance system.”

"Since the start of the Covid-19 pandemic in early 2020, the spread of RSV and other common respiratory viruses has been disrupted."

“RSV hospitalization rates are high in children. [who are less than] Their age is six months, but the rate of hospitalization has increased in older children compared to previous seasons.”

Most people focus on those who are at high risk for RSV, such as premature infants, young children with heart problems at birth, and those with – or who have – chronic lung disease. Depression prevention systems.

“Two-thirds of children admitted with RSV are healthy, normal children.”

But these patients account for only a third of hospitalizations, said Dr. James H.

“Two-thirds of children who get RSV are healthy, normal children,” said Conway, a professor of pediatrics at the Wisconsin School of Medicine and Public Health.

RSV hospitalization rates for adults have also increased, “with the highest rates of hospitalization among adults aged 65 and older,” a CDC spokeswoman said.

The most recent two weeks of RSV-NET data are subject to reporting delays, so the data should be interpreted with caution.

Why do some people get infected more than once?

“We’ve known for decades that immunity to most respiratory viruses — rhinoviruses or parainfluenza viruses or RSV — is not very good against naturally occurring respiratory viruses,” Conway said.

“That’s why people can get these infections so often.”

And just like the flu, people can get different types of RSV.

Children can actually get more than one case of RSV, experts say.  Similar to influenza, there are several types of RSV.

Similar to influenza, there are several types of RSV, so there is RSV-A [strain] And there is RSV-B. [strain] – Like a cold [type] A and flu [type] B,” Conway told Fox News Digital.

“People can often find it, because even if they have one, the cross defense is only partial.”

Once the virus enters the body, it is often difficult to prevent infection.

Our immune system is made up of several components, including antibodies — antibodies that protect our blood from foreign invaders and secrete antibodies, Conway said.

“There are parts of your immune system that are basically responsible for catching it [the virus and] “This is important,” he said [to] Bring your immune system and say, ‘This is something we have to deal with.'”

Orange County, County, has declared a state of emergency due to the virus outbreak.

But once the virus enters the body, it is often difficult to prevent infection, he added.

The next time the person is exposed to the virus, the immune system will remember it and “line up” the T cells to destroy the virus.

The first RSV vaccines for elderly people in the US may soon be available.

But as a temporary measure [the immune system] It takes your B cells and turns on the circulating antibodies, to get these viruses out of the bloodstream [perhaps] Before they get sick,” Conway said.

Vaccines are available for adults

As early as next fall, we may have the first RSV vaccines for seniors in the US, Conway said.

Several companies, including Pfizer, GSK, and Janssen, have RSV vaccines in late stages for adults, that is, the elderly.

“Infant immunization with monoclonal antibody injections has already been developed for high-risk premature infants, and long-acting versions for all infants are also on the horizon,” Conway added.
