What’s the risk of COVID-19 for a healthy young person?


The first particular person identified with COVID-19 in New Jersey was a 32-year-old man who had been admitted to the hospital.

In a video posted to Twitter over the weekend, the affected person defined that he’d had no underlying medical situations that might make him prone to extreme sickness, but the new coronavirus was making him sicker and sicker. He spoke from a hospital mattress the place he had been hooked as much as tubes serving to him breathe.

The video, which has been seen greater than 440,000 occasions, raised considerations that young folks could also be extra weak to COVID-19 than well being specialists had been letting on.

So is that actually true?

According to medical specialists, no. The risk of critical sickness on account of COVID-19 is way larger for people who find themselves older and have underlying medical situations. People 60 and older accounted for greater than 80% of the deaths in China, in accordance with a main examine in the Journal of the American Medical Assn.

But uncommon exceptions have popped up in the scientific literature, stated Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases.

“There will be, as we’ve seen in influenza, an occasional person, who’s young and healthy, who winds up getting COVID-19, seriously ill and dies,” Fauci stated in an interview with Dr. Howard Bauchner, the editor of JAMA. “But if you look at the weight of the data, the risk group is very, very clear.”

With the U.S. outbreak in its early phases, there isn’t but good knowledge on the ages and different traits of contaminated sufferers right here. So specialists have relied on the evaluation of practically 45,000 COVID-19 sufferers in China that was carried out by the nation’s Center for Disease Control and Prevention.

The examine accounts for greater than a third of all reported circumstances of the illness. Worldwide, 118,000 folks have been identified with the illness thus far and four,200 have died from it.

The examine recognized only a few deaths amongst folks beneath 40. More than 12,000 folks in that age group had been contaminated, however solely 26 died. It is unclear if these folks had different medical situations, resembling bronchial asthma or most cancers, which will have made them extra weak.

The examine discovered that the likelihood of dying from COVID-19 clearly will increase with age.

There had been no reported deaths from COVID-19 in youngsters beneath 10, and different research have steered that youngsters who’re contaminated don’t grow to be very sick.

These are the COVID-19 mortality charges by age calculated by the Chinese CDC:

  • ages 10-19: zero.2%
  • ages 20-29: zero.2%
  • ages 30-39: zero.2%
  • ages 40-49: zero.four%
  • ages 50-59: 1.three%
  • ages 60-69: three.6%
  • ages 70-79: eight%
  • 80 and over: 14.eight%

The general mortality price estimated by researchers was 2.three%, however specialists warning that it’s doubtless exaggerated on account of milder circumstances which have gone uncounted.

As for the youthful deaths, they characterize what you’d see for those who pored over any illness knowledge with a magnifying glass, specialists say.

“It is possible, but apparently very rare that otherwise healthy people can get severe disease,” stated Dr. Jeffrey Klausner, an infectious illness skilled at UCLA’s Fielding School of Public Health. “But right now we have patients in the hospital with severe influenza that were otherwise healthy people in their 40s and 50s. … It’s rare as well, but it occurs.”

Indeed, in the 2018-19 flu season, 2,450 folks between the ages of 18 and 49 died in the United States, in accordance with the CDC. The mortality price from the flu is decrease than from COVID-19, however much more folks caught the flu final season — greater than 35 million — than have gotten COVID-19 thus far this 12 months.

In an interview with a native CBS station in New York, the New Jersey COVID-19 affected person recognized himself as James Cai, who works as a doctor assistant. Cai stated he believes he contracted the virus at a convention in New York and inside three days was hospitalized as a result of it had unfold to his lungs.

“The virus is everything. Diarrhea, watery eyes, shortness of breath, chest pain, you name it. High fever,” he instructed the CBS station. “Every day is getting worse … it happened so quick.”

Cai isn’t the first particular person to lift considerations about how shortly folks grow to be severely unwell. The common time it takes for folks to begin displaying signs after an infection is about 5 days, in accordance with a new examine by Johns Hopkins University, however there have been studies of fast decline as soon as sickness units in.

At a information convention Sunday, Timothy Killian, spokesman for nursing residence Life Care Center in Kirkland, Wash., stated it had been “surprising and shocking” to see sufferers grow to be deathly unwell so shortly. At least 19 individuals who had been linked to the nursing residence have died, most of them of their 70s and 80s.

“We have found this to be troubling and volatile and unpredictable,” Killian stated. “We have seen as little as one hour, somebody getting no symptoms to going to symptoms that were severe enough that they needed to be transferred to the hospital, and then within a short amount of time, that patient died.”

Scientists are nonetheless studying extra about how the virus kills its victims. But it’s potential the older sufferers didn’t present the telltale indicators of the virus, together with a fever, that might have clued folks into the sickness earlier, Klausner stated.

Elderly folks don’t mount a fever the similar method that youthful folks do, as a result of their immune programs start to react in another way to viruses as they age, he stated. Nursing residence employees needs to be on the lookout for not simply fever but additionally cough, fatigue and complications, he stated.

“While they are brewing infection, it may go unnoticed,” Klausner stated.

Times employees writers Richard Read and Rong-Gong Lin II contributed to this report.
