2-month-old in Michigan dies from coronavirus, state health official says

LANSING, Mich. (WLNS) — A 2-month-old in Michigan has died from COVID-19, the state’s chief medical executive said on Wednesday.

According to Chief Medical Executive Dr. Joneigh Khaldun, the child is the youngest reported coronavirus fatality in the state and the only person under age 1 to die from the virus.

Dr. Khaldun said children are capable of transmitting the virus to other people despite their reduced likelihood of getting severely ill.

“Studies show that while children are less likely to get severely ill from COVID-19, they still can,” Khaldun said on Wednesday. “And they can also pass it on to others including adults who are more likely to get sick or ill from COVID-19.”

The American Academy of Pediatrics reported 549,000-plus cases of COVID-19 among children as of September 10. Overall, children represent 10 percent of all COVID-19 cases.

While the state declined to provide any other specifics about the 2-month-old’s death, Dr. Khaldun discussed MIS-C, a rare but dangerous illness striking children weeks after they get COVID-19.

Dr. Ritu Banerjee, a pediatrician specializing in infectious diseases and an associate professor at Vanderbilt University, recently shared answers to common questions about MIS-C. The Conversation, an independent and nonprofit source of news, shared her answers.

What is multisystem inflammatory syndrome (MIS-C)?

MIS-C is a rare but severe condition that can develop in children and adolescents who have been infected with SARS-CoV-2, the virus that causes COVID-19. It usually appears about 2-4 weeks following the infection.

As the name suggests, MIS-C affects multiple systems within the body. Young patients can develop a persistent feverabdominal pain, vomiting, diarrhea, rash, conjunctivitiscardiac damage and shock. They typically will have signs of inflammation, and some will have a decrease in the white blood cells called lymphocytes that protect the body from infection.

Unfortunately, we don’t yet understand why a small fraction of children develop MIS-C while the overwhelming majority of children with COVID-19 recover without problems. Nationwide, more than half a million children had been diagnosed with COVID-19 by early September, and fewer than 0.2% developed MIS-C.

What happens inside the body to produce such a wide range of symptoms?

MIS-C appears to be caused by dysregulation of the immune system, in which the body’s immune response gets out of control and harms the body itself. Doctors and scientists are trying to figure out why this happens.

The hyperinflammation can affect multiple organs at the same time. More than 70% of patients who are hospitalized are in the ICU, and about a quarter of those needed equipment to help keep their hearts and lungs functioning.

While the symptoms overlap a little with Kawasaki disease, another inflammatory condition, there are distinct differences. For example, MIS-C is more common in elementary school-age children, with an average age of around 8, while Kawasaki disease tends to affect children under 5. The low white blood cell counts found in children with MIS-C also aren’t as common in Kawasaki disease.

It’s becoming clear that MIS-C also has a range of illness, from milder forms that resemble Kawasaki disease to more severe forms that affect multiple organs and result in shock.

How is MIS-C treated, and can it cause long-term damage?

Doctors have been treating MIS-C with approaches that have worked for other diseases. These include intravenous immunoglobulin – a blood product with antibodies that suppresses the immune response – aspirin and steroids, which are also used to treat Kawasaki disease. Sometimes children with MIS-C are given blood thinners, medicines to support blood pressure, and other medicines to dampen the immune response.

Doctors don’t yet know whether children with MIS-C will have long-term damage.

Certainly, children with heart problems connected to the illness should have close follow-up exams with cardiologists. It is not yet known if children with milder forms of MIS-C are also at risk for cardiac injury.

Who develops MIS-C?

Racial and ethnic minorities are overrepresented among the children who have developed MIS-C in the U.S. and Europe. This may be because some groups have genetic factors that predispose them to the illness. However, social and demographic factors likely play a large role in this disparity.

Racial and ethnic minority groups are more likely to be front-line workers who are not able to work from home or social distance at work, and therefore are more likely to get COVID-19 and transmit it to their household members, including children. According to CDC data, in the first six months of the pandemic, nearly five times as many Hispanic and Black U.S. residents were hospitalized for COVID-19 as white residents.

What can parents do to keep their kids safe?

Parents should be aware of the symptoms.

If a child has trouble breathing, has severe abdominal pain, feels chest pain or pressure that doesn’t go away, has a bluish tint to the lips or face or exhibits new confusion or trouble staying awake, take the child to a hospital immediately. Other symptoms include bloodshot eyes, a rash, neck pain, diarrhea, vomiting and fever.

Everyone has a part in preventing more children from developing MIS-C by preventing COVID-19 infections in the first place.

If we all wear masks, social distance and wash our hands frequently, we can reduce transmission of COVID-19 to others in our households and in our communities.
