More than 1 in 4 children hospitalized with Covid or MIS-C have had symptoms for months, study finds

(CNN)Nearly 30% of children were hospitalized with Covid-19 or MIS-C. A new study found that people had symptoms for months or longer after diagnosis.

The most common symptoms among children hospitalized with Covid-19 were fatigue, shortness of breath, coughing, headaches, muscle aches and body aches, according to the study, published Friday in Pediatrics. pain, fever.

MIS-C is a rare condition that often, but not always, affects children after Covid-19 infection. Doctors don't know exactly what's causing it. This condition appears to last for several weeks after infection and can cause inflammation in certain parts of the body.It can affect major organs such as the kidneys, brain, lungs and heart.

For children with MIS-C, 'disability' (inability to perform usual activities) was the most common symptom in this study. Other severe symptoms included inability to exercise or even walk as usual, sleeping more than usual, and difficulty concentrating at school.

} As of last week, nearly 14.2 million children in the United States have tested positive for Covid-19 since the pandemic began. Some studiesestimate that between 2% and 10% of all children diagnosed with Covid-19, not just hospitalized children, develop long-term Covid. However, doctors believe that the problem is greatly underestimated.
As of August 1, he had 8,798 children whose illnesses met her MIS-C definition, according to the US Centers for Disease Control and Prevention.

For patients with MIS-C, a new study found a higher proportion of children with severe Covid needed intensive care-level support during hospitalization. Children who had asthma and obesity seemed more likely to develop symptoms after being discharged from hospital. A survey of 358 children treated at a pediatric hospital in This was before the surge in cases caused by Delta or Omicron variants. It is unclear whether children had different outcomes with those variants.

This study period was also before the children were eligible to receive her Covid-19 vaccination.

"Children's vaccination rates are still not very high, but vaccines can prevent this," said study co-author Adrian Randolph, Ph.D. Senior Associate and Professor of Anesthesiology in the United States. Harvard Medical School told CNN. Randolph's previous research has found that vaccination helps prevent her from MIS-C and serious illness in children.

The encouraging news, Randolph said, was that most children hospitalized with MIS-C or Covid remained symptom-free for months after initial infection.

There were also far fewer long-term Covid cases among hospitalized children than among hospitalized older adults, she said. , the risk of serious illness and lingering complications for children hospitalized with Covid-19 is higher than the risk of severe side effects from very rare vaccines. We believe that we are underestimating the risk if we do not vaccinate.

``People will say, 'Kids don't get sick very often. Hospitalization itself is also very devastating I don't want my child to be hospitalized with severe pneumonia I'm on my period May affect future lung function MIS-C affects their minds,” said Randolph. "Hopefully, this data will help people understand exactly how important vaccination is."
