Adults can sometimes suffer dangerous symptoms, which resemble a coronavirus-related syndrome in children, researchers from the US Centers for Disease Control and Prevention (CDC) said.
According to CNN, they call it multisystem inflammatory syndrome in adults or MIS-A and they say it is similar to multisystem inflammatory syndrome in children or MIS-C.
Like MIS-C, MIS-A is not clearly related to the coronavirus and people who have it may not have other symptoms that indicate a Covid-19 infection.
But MIS-A has killed at least three patients and, like Covid-19, disproportionately hits racial and ethnic minorities, the CDC team said.
A black man living in Florida had hearing problems, claiming to hear all kinds of noises, but also vomiting and chest pain. He tested negative for Covid-19 when he was hospitalized, but died despite treatment. He was 46 years old.
A 22-year-old black woman from New York was healthy until she developed a fever and chills, after which she spent 19 days in the hospital before being discharged, the CDC team said.
MIS-C has affected hundreds of children around the world, and if this condition is treated quickly, children will recover. It causes generalized inflammation, but patients do not usually have the classic symptoms of the coronavirus. Blood tests indicate that MIS-C can develop a few weeks after a child has recovered from a coronavirus infection, usually a case that has caused mild symptoms or even zero symptoms.
The CDC team described the cases of 27 adults ages 21 to 50 who had similar symptoms. Most had extreme inflammation throughout the body and dysfunctions in organs, such as the heart, liver, and kidneys, but not in the lungs.
“Although hyperinflammation and dysfunction of extrapulmonary organs have been described in adults hospitalized with severe Covid-19, these conditions are generally accompanied by respiratory failure.“They wrote in the CDC’s weekly report on death and illness, MMWR.
“In contrast, the patients described here had minimal respiratory symptoms, hypoxemia (low blood oxygen level), or radiographic abnormalities as defined by the case study, to distinguish MIS-A from a severe Covid-19 infection; only eight of the 16 patients had documented respiratory symptoms prior to initiation of MIS-A. “
