Ill, according to a Coronavirus infection immune? Study shows results

Chinese researchers have taken 74 people from Chongqing under the magnifying glass, which were suffering from the Coronavirus. Including patients suffering from a severe course of the disease and showed no symptoms were. Only 62.2 percent from the group without symptoms had only a few weeks after infection, even short-term antibodies in the blood, compared with 78.4 per cent of the symptomatic patients. The study was published Thursday in the journal “Nature Medicine”.

After eight weeks, the number of antibodies was decreased in the first group to 81.1 percent, in the case of the people with symptoms to 62.2 percent. In addition, were found in asymptomatic patients and less to the immune response, involved in cell proteins, suggesting a weaker immune response to the new Coronavirus.

Immunity identification of the Coronavirus

“This data could also identify the risks associated with the use of Covid-19-‘Immunity’ point,” write the authors of the study. The results challenged the notion that everyone who has an infection, be against future infections immune. So far, many of the immunological data were derived for the Coronavirus pandemic of hospital patients with severe forms of the disease, said Danny Altmann, Professor of immunology at Imperial College London. Most of the Infected have only mild or no Symptoms. It is, therefore, a crucial question is whether they, too, had a long-lasting, protective immunity.

Many of the patients in the study within two months, a significant decrease in the antibody, was “an important and potentially worrying issue”, said Altmann, who was not involved in the study. “Although it is a relatively small sample of patients, there are concerns that the natural immunity against coronaviruses and can be quite short-lived.”
