Scientists from the Centers for Disease Control and Prevention and the health departments of 4 states — Georgia, Illinois, Massachusetts and Rhode Island — described a 13-year-old lady who turned contaminated with the coronavirus simply earlier than a three-week household gathering. Eleven different family, together with her mom, her father, two brothers and two grandparents, additionally turned contaminated.
“This outbreak highlights several important issues,” wrote the authors, led by Dr. Noah G. Schwartz of the C.D.C., within the article, which was printed on Monday. “First, children and adolescents can serve as the source for Covid-19 outbreaks within families, even when their symptoms are mild.”
The discovering, which appeared within the C.D.C.’s Morbidity and Mortality Weekly Report, might also match with claims that youngsters are extra probably grow to be contaminated and unfold the virus than youthful youngsters.
“This doesn’t necessarily mean that all 13-year-olds can cause outbreaks like this,” mentioned William Hanage, a professor of epidemiology on the Harvard T.H. Chan School of Public Health who was not concerned with the analysis. “But it does mean that some 13-year-olds can.”
The potential for kids to transmit the illness is “now pretty much established,” Dr. Hanage mentioned.
In the brand new case report, the lady was uncovered to the coronavirus away from home in June, the authors reported. However, 4 days after the publicity, a speedy antigen take a look at reported a detrimental consequence. Antigen assessments for the coronavirus, nonetheless, typically produce misguided outcomes. Two days later, she skilled nasal congestion, her solely Covid-19 symptom.
The similar day, she, her dad and mom and two brothers traveled to a get-together of 20 family over the following three and a half weeks. Fourteen of them stayed within the five-bedroom, two-bathroom home at various lengths of time starting from eight to 25 days; they didn’t put on face masks or keep not less than six toes other than one another. Six different family got here by throughout two days — as soon as for 10 hours, the opposite time for 3 hours — however maintained bodily distance and remained outside, though they too didn’t put on face masks.
Of the 14 staying on the home, 12 of them, together with the lady, got here down with Covid-19, with the onset of signs showing as much as 18 days after the beginning of the gathering. Their ages ranged from 9 to 72. Not all of them had been more likely to have been immediately contaminated by the lady; the virus could have been unfold by a number of folks in the home.
One was hospitalized, and one other went to an emergency room due to bother respiration. Both recovered. No extra circumstances have been linked to the household gathering.
Two of the ladies’ cousins, 14 and 16 years outdated, didn’t contract the coronavirus. None of the day guests who stayed exterior the home turned ailing.
“It re-emphasizes the importance of basic public health precautions, even with people we know and love,” mentioned Dr. Megan L. Ranney, a professor of emergency drugs at Brown who was not concerned with the research.
Those embody avoiding areas indoors the place individuals are shut collectively. “Staying outside is always safer, as shown by transmission rates within this study,” Dr. Ranney mentioned.
It additionally illustrated that different suggestions of public health officers have benefit: that bodily distancing helps forestall unfold of the coronavirus, that speedy antigen assessments needs to be confirmed by extra dependable polymerase chain response assessments and that somebody uncovered to the coronavirus ought to stay remoted from others for 14 days.
“Physical distancing, face mask use, and hand hygiene reduce transmission; gatherings should be avoided when physical distancing and face mask use are not possible,” the authors wrote.
