Record-Breaking Coronavirus Infections Among Children Prompts Concerns of MIS-C | Health News

Corona virus cases and hospitalization Among children, it is at an all-time high, raising concerns about a rare but serious syndrome that appears in children several weeks after infection with COVID-19.

MIS-C, or pediatric multisystem inflammatory syndrome, is a condition associated with COVID-19 in which various parts of the body are inflamed, including the heart, lungs, kidneys, brain, skin, eyes or digestive system organs, according to the Centers for Disease Control and Prevention. The cause of the syndrome is unknown.

The syndrome usually appears two to six weeks after infection with COVID-19, and its symptoms include fever, stomach pain, blood congestion in the eyes, diarrhea, dizziness, rash, and vomiting.

While MIS-C is rare — and the CDC has documented more than 6,400 MIS-C cases and 55 deaths as of January 3 — the current increase in coronavirus cases among children likely means more cases of MIS-C are emerging. almost.

If you have more children [COVID-19] “Then you’ll see more MIS-C,” says Sophie Katz of Vanderbilt University Medical Center. “I think that’s just what will happen.”

The CDC reported that the average age of patients with MIS-C was 9 years, and half of the children with the syndrome were between 5 and 13 years old. The majority of patients reported were male.

MIS-C has been reported in every state. Georgia and California have reported the most cases, with more than 400.

A particular concern with MIS-C is inflammation of the heart.

“When that happens, we usually see kids who are seriously ill — kind of in shock — and their heart … is not pumping as well as it normally should,” says Katz, who is an assistant professor of pediatric infectious disease.

The average hospital stay with MIS-C is five days. Katz says about 98% of patients with MIS-C are back to normal with a one-month examination.

According to Katz, most patients do well with treatment, which can include intravenous immunoglobulin and steroids.

But as more children become infected with the coronavirus due to the spread of the highly transmissible omicron variant, more of them are likely to contract MIS-C as well.

“Every pediatrician I know is worried that we will see big spikes in both [COVID-19] And MIS-C after that [the holidays]Wendy Husson, MD, a pediatric intensive care unit physician in Portland, Oregon, and also a spokeswoman for the American Academy of Pediatrics, Tell US news last month.

So when will experts know if omicron leads to an increase in MIS-C? Katz says the rise will be delayed by three to four weeks after the coronavirus surge.

“I kind of prepare myself for larger numbers of MIS-C with an omicron wave in about a month or so,” Katz says.

Coronavirus cases among children have recorded “the highest number of cases reported since the beginning of the epidemic,” according to Transfer From the American Academy of Pediatrics and the Children’s Hospital Association.

More than 325,000 pediatric infections were reported in the week leading up to December 30, according to the report. That’s nearly 65% ​​more than the previous week.

“Nearly 7.9 million children have tested positive for COVID-19 since the onset of the pandemic, which is more than 1 in 10 children in the United States,” the report said.

Despite reaching record levels already, more infections are expected among children, according to experts warning.

Infectious disease expert Anthony Fauci said this week that while the highly contagious omicron variant appears to cause milder disease From Delta, “The sheer scale of infection due to its high transmissibility means that many children will become infected.”

“As more children become infected, a certain proportion of them – usually children with comorbidities – will end up in the hospital,” Fauci said during a press briefing. “This is just an inevitable.”

Something to watch for, Katz says, is the emergence of more cases of MIS-C in children who did not know they had COVID-19 previously. Many cases of MIS-C occur in children who have mild or asymptomatic COVID-19 symptoms, and this trend is expected to continue with the omicron variant.

While the CDC has encourage Parents should vaccinate their children against the coronavirus in order to protect against MIS-C, vaccination rates among children remain far lower than experts would like to see.

Only 16% of children ages 5 to 11 are fully vaccinated, and more than half of children ages 12 to 17 are fully vaccinated, according to data from the Centers for Disease Control and Prevention (CDC). The vaccine is not yet approved for children under the age of five.

The vaccine has been absorbed into children aged 5 to 11 and 12 to 17 years noticeably slowed downAccording to a survey conducted by the Kaiser Family Foundation last month.

A new study published by the CDC on Friday found that the Pfizer coronavirus vaccine was highly effective in preventing MIS-C in children ages 12 to 18.

Of the 102 MIS-C cases examined by the study, 95% of patients were unvaccinated. According to the study, not all patients who needed resuscitators were vaccinated.

“This analysis provides supportive evidence that vaccination of children and adolescents has high protection against MIS-C and COVID-19 and emphasizes the importance of vaccinating all eligible children,” the researchers wrote.
