Only about 1.5 percent of the in a Hamburg study tested children and young people have antibodies to the Coronavirus in the blood. This will show that you can be removed from a herd immunity to the extent that the researchers of the University hospital Hamburg-Eppendorf (UKE) on Friday at the presentation of the interim results said. They were looking for out of a total of 2436 children and young people to have antibodies against the Sars-CoV-2 Virus in the blood. Only 36 of them you found which.

another result of the until the end of June the current study: In the case of older children, antibodies against the Coronavirus Sars-CoV-2 to prove more frequent than in younger. "This could be related to the fact that these children with age have a larger Radius and an increase in the contact activity to the outside," said Ania C. Muntau, Director of the clinic and polyclinic for child and youth medicine of the UKE. "Maybe it's just a question of social behavior."

In the age group of 0 to 9 years were reported to be one percent of a positive antibody detection, in the age group 10 to 18 years of two per cent. The difference was not statistically significant. The probability to have a positive antibody test increases with the children in the study with increasing age, it said. "With each year of age to eight percent."

In the case of 3107 subjects, the researchers took nose and throat swab, to an acute infection demonstrate. In the case of any of the children, the result was positive. "From this we can conclude that the Lockdown actions for the children and young people were in Hamburg," said the Professor more.

Also 964 children and young people with chronic conditions were investigated. It was interesting that children with pre-existing conditions when the antibodies were less frequently affected, said Muntau. In children without pre-existing conditions it will be 1.7 percent, with a pre-existing one percent. "That is to say, perhaps, that you will be more protected."

In the study C19.CHILD of Hamburg data of around 6000 healthy and chronically ill children and young people with and without symptoms of a Covid-19 infection involved. In the study, all of the other children in Hamburg were involved in addition to the child-UKE clinics.
