Children may suffer from coronavirus CoVID-2019, but tolerate it easier
Source:For 10 weeks the world's attention focused on the outbreak of the new coronavirus, but what scientists know about him? The available evidence suggests that the virus is able to spread airborne and contact routes, and an average person can infect about 2.2 others. But over time, particularly relevant was the question of sick children CoVID-2019. Recently, we you that the new coronavirus even affects Pets, but still, there were relatively few cases among children. Today, the researchers came to the conclusion that children may suffer coronavirus just in a simple way. But why?
Children may suffer from CoVID-19 but in another way
According to the results conducted by researchers from Johns Hopkins University and Chinese experts, from more than 72 000 confirmed cases in China, children under the age of 10 years was less than 1%. Of 1023 deaths registered in China, in the midst of the outbreak, there was not one child. But why? As a rule, all respiratory pathogens primarily striking two groups – the young and the elderly, but in the case of coronavirus, everything is different. As shown by the results of meta-analysis, it's not that children are somehow immune to CoVID-2019. They are just a fan, not so much.
According to the authors of the study publication , children exposed to infection with the novel coronavirus as adults. In the early Chinese researchers followed the spread of infection by observing the condition of people with fever in the hospitals and local clinics. All health staff has identified 391 patients with CoVID-19 and 1286 people who may have been exposed. The researchers monitored the patients quarantined to determine how to manifest the symptoms and is it possible to recover the novel coronavirus unnoticed. The team found that children aged 9 years and younger are also vulnerable to infection as other age groups. The symptoms in children has not been expressed so vividly as adults. Moreover, many children did not manifest any symptoms. The work is published on the server of preprints .
Can children play a role in the spread of coronavirus?
The findings do not explain why children develop a mild form of the disease. But earlier conducted a genetic relative of the virus SARS-CoV-2, gives some clues: in the course of the outbreak in 2003, no young person under the age of 24 years died. In severe cases, atypical of the patient first observed the fever and cough, and the virus rapidly multiplied in the lungs. About a week health improved, but began the second more severe phase of the disease. The results from another then have shown that high mortality in the second stage of the disease was not caused by the virus, and the immune response to the pathogen. In the risk group were people of more advanced age.
Scientists believe that closing schools will help stop the spread of infection
You May take years before scientists figure out the mechanism underlying why CoVID-19 less harmful to children. However, the most alarming is another question: if children can be infected, they are likely to play a role in further spread of the disease, as their milder symptoms may go unnoticed. For this reason, the researchers believe, closing on quarantine schools could be an important step to prevent further transmission.
