As Omicron cases decline, healthcare professionals are preparing for a potential rise in hospitalizations due to multisystem inflammatory syndrome in children (MIS-C). The challenging Omicron wave has presented numerous hurdles for parents, especially amid conflicting information regarding safety protocols in schools.
Although the Omicron variant appears to be receding, medical experts are bracing for a familiar trend observed throughout the pandemic: an increase in MIS-C cases following the peak of a variant. This rare but serious condition can manifest weeks after a child has contracted Covid-19, resulting in dangerous inflammation of critical organs such as the heart, lungs, brain, and kidneys.
According to the Centers for Disease Control and Prevention (CDC), approximately 4.5 million children were infected with Covid-19 in January 2022 alone. While the exact cause of MIS-C remains unclear, studies have shown a correlation between MIS-C and previous Covid-19 infections. “It consistently follows the same timeline,” said Dr. Emily Hayes, chief of infectious diseases at Children’s Health Center in Los Angeles. “We notice a spike in cases two to six weeks after a variant peak, and then MIS-C cases begin to rise.”
Symptoms and Causes of MIS-C
MIS-C presents a variety of symptoms, which can differ from child to child. Common symptoms include abdominal pain, vomiting, diarrhea, rashes, conjunctivitis, and low blood pressure. These symptoms typically appear four to six weeks after a Covid-19 infection and may resemble a resurgence of Covid itself. Doctors emphasize the need for prompt medical attention if symptoms worsen, as delays in treatment can have dire consequences. “There have been tragic cases where children did not reach emergency care in time,” remarked Dr. Sarah Lee, a pediatrician at a major hospital in New York City.
The Wisconsin Department of Health Services reported the first child death linked to MIS-C associated with Covid-19 on February 18, 2022. While the precise factors that lead to MIS-C in some children but not others remain unknown, it is observed that MIS-C often occurs following what is described as mild or asymptomatic Covid-19 cases. The condition predominantly affects elementary school-aged children, particularly those around 8 or 9 years old, although instances in younger and older children have been recorded.
Vaccination Reduces MIS-C Risk
Some hospitals in the U.S. have experienced a decrease in MIS-C hospitalizations, which experts attribute to increased vaccination rates among children. “Older children are showing much lower rates of MIS-C, likely because they are vaccinated. Numerous studies indicate that vaccination significantly reduces the risk of MIS-C, as well as severe disease and hospitalization,” stated Dr. Hayes.
A CDC study from January 2022 supports this finding, indicating that vaccination reduces the likelihood of MIS-C by an impressive 91%. Among adolescents hospitalized for MIS-C, 95% had not been fully vaccinated. Notably, none of the vaccinated MIS-C patients required life support.
Treating Covid-Associated MIS-C
Most children diagnosed with MIS-C require hospitalization to ensure proper treatment and prevent lasting organ damage. Pediatric intensive care units are equipped to manage MIS-C patients, providing fluids for dehydration, oxygen for breathing difficulties, steroid therapy, and targeted treatments to mitigate inflammation. Fortunately, children treated for MIS-C early in the pandemic generally show no lasting effects from the condition. According to research published by the American Heart Association, most children recover completely, even after experiencing severe cases.
Parents are strongly encouraged to have their eligible children vaccinated to diminish the risk of developing MIS-C post-Covid. Currently, there is no vaccine authorized for children under five, making it even more crucial for adults around younger children to be vaccinated.
