With schools and colleges reopening across the country, scientists say the social distance of Kovid-1 to is a serious public-health reaction. New research released Thursday will shed more light on children who test positive for COVID-19, and who are infected with the coronavirus. Children are always asymmetrical or show very few symptoms, and the research provides insights into the course of the disease at important times for families and communities.
A study published in the latest edition of the Journal of Pediatrics found that viruses and antibodies can coexist in young patients. “With most viruses, when you start looking for antibodies, you won’t find the virus. “But with Covid-19, we’re seeing both,” says Burak Bahar, lead author and director of Laboratory Informatics at Children’s National Hospital in Washington DC. “This means that antibodies also have the potential to infect children with the virus.” Have been found. “
“
“Even if antibodies are found, children are more likely to be infected.”
”
Researchers have studied SARS-CoV. -2, the virus caused by COVID-19, and the analysis of 6,369 children tested on 215 patients who underwent antibody testing at Children’s National between March 2020 and June 2020. Of these 215 patients, 33 tested positive for both viruses and antibodies during the course of the disease. Nine of those 33 people also showed the presence of antibodies in their blood when tested positive for the virus.
The researchers found that patients between the ages of 6 and 15 took longer (average time of 32 days) to clear the virus, meaning they left their systems, compared to patients between the ages of 16 and 22 (a. 18 days). Average). Women in the 6 to 15 age group also took longer to remove the virus than men: an average of 44 days for women as against 25.5 days for men. “We can’t just disappoint our guards because the baby has antibodies or doesn’t show symptoms for long,” Bahar said.
The study also found that the average time from viral positivity to negativity was 25 days – the moment when the virus could no longer be detected; It took 18 days to go from viral positivity to seropositivity – or the presence of antibodies in the blood – and 36 days to reach a sufficient level to neutralize the antibodies. The researchers wrote that these “neutralizing antibodies” were important in protecting a person from possible relapse of the same virus.
Four important caveats: First, the number of children in this study was relatively low. Second, the next stage of research will be to check whether the coronavirus present with antibodies to the disease can be transmitted to others. Third, scientists need to find out if antibodies are compatible with immunity, and fourth, they need to establish how long the potential defense from antibodies and reinfection really lasts. As such, the outside repeats the need for social distance.

A separate study published this week in Pediatrics suggests that children can spread SARS-Co-2, even if they never develop symptoms or even after a long, long, long, long, long, long, long, long, long, long, long, long, long, long, long, long, long, long, long, long, long, long, long, long . It showed that children continued to “shed” the virus through their respiratory tract for a long time and, therefore, could potentially remain infected. The researchers also found that the duration of COVD-19 symptoms varied widely from three days to about three weeks.
A recent systematic review estimated that 16% of children with SARS-Cavi-2 infection are pathological, but evidence suggests that the U.S. Department of Disease Control and Prevention According to the centers, about 45% of pediatric infections are pathological. The signs and symptoms of Covid-19 in children are similar to other infectious and non-infectious processes, including influenza, according to the CDC.

Under pressure from the teachers’ union to delay the start of the school year, New York City Mayor Bill de Blasio announced Tuesday that the individual class would be pushed back until September 21, 11 days after the plan. Remote Learning, originally scheduled for September 10, will now begin on September 16. Other countries have not performed so well with school resumes. Israel, which also resumed schools this week, erupted when it resumed schools on May 17.
Outside teachers and students were also advised to wear masks. To reduce the risk of COVID-19 spreading, it is more appropriate to use a high-quality cloth or surgical mask with a plain design instead of a facial ield and a mask equipped with a respiratory valve, published by Flu Phys Aids in a monthly published peer-reviewed science. Journal, covering fluid dynamics, founded in 1958 by the American Institute of Physics.
As of Saturday, COVID-19 had infected 26,623,562 people worldwide, mostly not responsible for asymptomatic cases, and killed 874,717 people. The U.S. still has the highest number of Covid-19 cases in the world (6,200,518), followed by Brazil (4,091,801), India (4,023,179) and Russia (1,011,987), according to data collected by Johns Hopkins University.
Meanwhile, U.S. Cases continue to rise in while California became the first state in the country to surpass 700,000 confirmed cases; By Saturday the infection had reached 730,662, with 13,638 COVID-related deaths. 437,971 infections have been reported in New York and U.S. (32,982).
