Children get new coronavirus infection COVID-19 less adults, typical for many older patients the symptoms they do not appear, however, virus RNA longer detected in their feces, is reported in Nature Medicine. Possibly, the virus from children to others is often transmitted by the faecal-oral route.
Most cases of infection of SARS-CoV-2 (the causative agent COVID-19) found in adults. Morbidity and mortality among children is the lowest. It is necessary to understand, whether so it actually and what role the younger age groups play in the spread of the virus.
The employees of the Medical University in Guangzhou under the leadership Katanga Gong (Gong Sitang) has processed information about 745 3174 children and adults who have close contact with an infected in a two-week period before seeking medical attention. (Ill give interferon to combat the virus.)
RNA from these patients identified by the method of real-time PCR with reverse transcription (RT-PCR) swabs from the nasopharynx. Doctors determined the incidence in these two groups and compared the symptoms of coronavirus infection in children and adults. The researchers also were daily taken from the infected swabs from the anus and with the help of RT-PCR were looking for in them genetic material of the SARS-CoV-2.
Polymerase chain reaction identified the new coronavirus have 10 children and 111 adults. This is 1.3 and 3.5 percent of the total population of the relevant age group. The numbers differ by 2.7 times, and this difference was statistically significant (P = 0.002). The age of affected children ranged from 2 months to 15 years, six were boys. They all entered the treatment independently from each other.
Many of the symptoms typical for acute respiratory syndromes in children is not apparent. Have three had fever (though all on admission body temperature did not exceed 39 degrees Celsius), the five — cough, and rhinitis was observed only in two. Computed tomography of the lungs did not reveal unequivocal signs of pneumonia, and “symptom frosted glass” found only half of young patients.
The most common adult symptoms COVID-19, such as headache, muscle weakness, vomiting, nausea and disorientation in children have not been observed. All this suggests that many cases of coronavirus infection among the young population is not revealed due to the atypical clinical picture.
