Antibody levels can remain high for up to 9 months after infection with the coronavirus

سطح آنتی‌بادی می‌تواند تا ۹ ماه بعد از ابتلا به ویروس کرونا بالا باقی بماند

A test by residents of an Italian city shows that antibody levels remain high after nine months of being infected with the corona virus. These tests showed that there was not much difference between people who had previously had symptomatic coronation and those who had asymptomatic disease.

Researchers at the University of Padua and Imperial College London in February and March 2020 tested the corona in more than 85% of the people of the commune of Wu in Italy and again visited them in May and November 2020 to measure their antibody levels. کردن. The results of this research are published in the journal Nature Communications Published, it shows that 98.8% of people who were previously infected also had a detectable level of antibodies in their body in November.

The researchers measured the antibody level in three ways and found that although the antibody drop was seen between May and November, it varied depending on the measurement method. They say the level of antibodies has even increased in some people because they have taken the corona again.

“There is no evidence that there is a significant difference in the level of antibodies between those with and without the coronary artery coronary artery disease,” said Dr. Ilaria Dorigati and Abdul Latif Jamil. “It means that the ability to react safely does not depend on the symptoms and the severity of the infection.”

The researchers said their study measured a 2.2 percent chance of contracting the coronavirus outside the family, a 26 percent chance of getting it from family members, and 79 percent of the virus being transmitted through 20 percent of those with the worst conditions. have.

“Our research shows that if extensive testing is not done, manual tracking of people’s communications, that is, the search for those who have been in contact with the infected person, has a limited effect on epidemic control,” said Professor Andrea Cristanti.
