Why coronaviruses attack children’s color more often

One of the notable features of the new coronovirus, which appeared early in the epidemic, was that it largely spared children. Some become seriously ill, but deaths are much lower than in adults.

But people of color are renewing concerns about Kovid-19, a disease caused by coronavirus, and recent studies about children’s susceptibility in these communities.

They are infected at higher rates than white children, and are hospitalized five to eight times more often than white children. Children of color irritate the majority of people who develop a life-threatening complication called multi-systemic inflammatory syndrome or MIS-C.

According to the Centers for Disease Control and Prevention, more than 180,000 Americans have died, of which less than 100 children Kovid-19 have died. But children of color comprise the majority of those who died from Kovid-19.

The dead included 41 Hispanic children, 24 black children, 19 white children, three Asian-American children, three American Indian / Alaska Native children and two multinational children.

The unique weaknesses of these young people are also coming to the fore when the number of children is increasing and the schools and parents across the country are struggling with Nettles’ decisions about reopening safely.

Minority children’s susceptibility to this disease is not unique in the United States. According to a study published last week in the journal BMJ, black children in the United Kingdom were more likely to move to critical care and develop MIS-C than whites.

Dr. Pediatric Emergency Specialist of Children’s National Hospital in Washington. “Children are not present in the void,” said Monica K. Goyal.

In Washington and 1,000 children were tested for Kovid-19 at a site in March and April, about half of Hispanic children and about a third of black children were positive for coronovirus, Drs. Goyal found in a recent study.

“They live in homes where their parents or caregivers do not have the luxury of telecommuting, so they are at increased risk,” he said. “They are also likely to live in multicultural homes. It’s all connected.”

Poverty is also associated with a higher risk of infection, and Drs. Goyal’s research journal Pediatrics, published on Tuesday, found that children from low-income families were more likely to be infected by the most affluent parents.

Higher infection rates appear to be induced by greater exposure to the virus, Drs. Goyal said: “There is nothing to indicate that Kovid has some sort of genetic tendency based on race or ethnicity.”

Stanford’s pediatrician Drs. Yvonne Maldonado agreed: “I know exactly what is happening to those children. Their parents are frontline, blue-collar or essential workers. ”

Dr. Maldonado said that he often treated adult patients with coronovirus who stated that their partner or children were ill, as well.

Researchers at Harvard have documented high infection rates in Massachusetts communities with high proportions of immigrants, high numbers of food service workers, and high numbers of people living in large, shared homes.

Immigrants may hesitate to obtain medical care, and employees who work in the food service industry often lack adequate paid sick leave, Jose Figueroa, Health Policy and Management at Harvard TH School of Public Health The assistant professor said.

“You have the right recipe for rapid transmission of Kovid-19 in the Latino community,” he said. “Working adults who continue to go to work because they need to have food at the table and pay rent, and who often have young children.”

While the patrons of the restaurant worry about the distance between the tables and wonder whether to dine on the street, “someone is preparing food, and they don’t have the luxury of being on the street,” Dr. . Figueroa said. “They are in small kitchens cooking, and even though they are wearing masks, they are often in small, confined spaces.”

The exact number of children infected with coronovirus may not be known, as younger children have a mileage course of the disease and have not been routinely tested in the United States.

A mother in the Bronx who asked to be identified only as Darlene to protect her child’s privacy, her son had been ill for months during the spring of a coronovirus outbreak in New York City. But health providers in the Bronx disregarded her repeated requests for a 3-year trial in March, and through April, because she had no fever and difficulty breathing, he said.

When she managed to get her tested in April, the result was negative. But his son had lethargy, complained of stomach ache, had frequent diarrhea and often woke up at midnight.

Typically an active and playful child, she had difficulty walking and falling several times, Darlene said: “I knew something was wrong – it wasn’t my baby.”

Finally, in June, while his symptoms were resolving, Darlene was able to take him to his regular doctor at Mount Sinai Hospital in Manhattan, which tested him for antibodies to the virus. The result was positive, indicating that he was indeed infected. (Other family members tested negative for antibodies).

Dr. Goel’s study reported that Hispanic children were six times more likely to test positive for coronavirus than white children who came to the test site in Washington. Black children were twice as likely to test positive as white children.

Two other reports last month by the CDC underscored the increased risk of poor outcomes for children of color.

Hispanic children were at greatest risk of serious illness: they were hospitalized at a rate of about eight times that of white children, according to the CDC, black children were hospitalized at a rate five times higher than white children.

The CDC study, which looked at 576 children under the age of 18 who were hospitalized in 14 states between March 1 and July 25, found that nearly half had at least one underlying health condition. The most common was obesity, followed by chronic lung disease and premature birth.

Among hospitalized children whose race and ethnicity was known, approximately half were Hispanic, and 29 percent were black. Hispanic and black children also had higher rates of underlying health conditions: 45 percent and 29 percent, respectively. Among white children, 15 percent had underlying health problems.

Another CDC paper looked at 570 children with MIS-C in 40 states, the District of Columbia and New York City between March 2 and July 18. Of those whose caste was known, only 13 percent were white; 40 percent were Hispanic, and 33 percent were black.

Just under 3 percent were Asian, and about 10 percent were listed as “other” or multinational. Less than 1 percent of the children were American Indian / Alaska Native or Native Hawaiian / Pacific Islander.

Two-thirds of children had no prior medical condition before the onset of MIS-C, although the proportion of those who were obese was slightly higher than the general population. The most common symptoms were abdominal pain, vomiting, a skin rash, and diarrhea.

While children have been the least severely affected by the disease between the second and third weeks of August, according to the American Academy of Pediatrics, there has been a 21 percent increase in children.

The academy estimates that children represented 9.5 percent of all cases in states that have confirmed infection in 476,439 children in six million Kovid-19 cases in the United States. (The definition of a child varies from state to state, but is usually 18 and under or less than 18.)

Since most of the virus-infected children have mild or asymptomatic disease, many cases have been missed earlier this year, when testing was rare and limited to the very sick, Drs. Alefia Malbari, Assistant Professor of Medicine, Icon School of Medicine at Mount Sinai in New York.

When the parents called their pediatricians and said they had symptoms in their children, “Our line was, ‘This may be Kovid – quarantine yourself as if you had Kovid,” Dr. Malbari said. “Even the playgrounds were closed, so it was easy to do that.”

Now, with school opening and more widely available testing, “we have to take these symptoms really, really seriously.”
