An initial study conducted in Israel has revealed that between 200,000 and 300,000 people in the country have been infected by the Coronavirus (COVID-19), about 2.5% of Israel’s population.
The survey, conducted by Tel Aviv University and MDA among 1,700 people from all over the country and in all age groups, relied on serological testing for Immunoglobulin G antibodies.
The IGG antibodies indicate a response by the body’s immune system to the virus and are the most common type of antibody found in blood circulation.
Such a reaction usually develops two or three weeks after exposure and also occurs in people who have been infected by the virus but have not developed the symptoms of the disease.
The presence of antibodies was slightly higher in the 40-60 age group, and lower in the 0-19 age group. Another figure discovered was the higher prevalence of the antibodies in men compared to women.
Israel has 17,169 confirmed Coronavirus cases.
Professor Danny Cohen, Head of the School of Public Health at Tel Aviv University who led the testing, noted that for every confirmed case, there are 11 to 16 other cases that have not been documented.
However, he said that Israel is far from the 60% infection rate that is required to achieve herd immunity.
