“The experience gained shows that even in mild Covid-19 cases the patient continues to emit the virus for a long time. In Bulgaria quarantine is only lifted if the patients are not emitting the virus,” said Prof. Todor Kantardzhiev, director of the National Centre of Infectious and Parasitic Diseases..

He added he was pleased that there were no new cases in old people’s homes and care homes for children with mental disabilities. In Prof. Kantardzhiev’s words the epidemic expands when one coronavirus patient infects three other people. With ordinary flu one patient infects two other people. At the moment one Covid-19 patient is infecting between 0.8 and 1.2 people in Bulgaria. At the beginning the ratio was 1 to 1.7. There is success regarding one other index as well – the time it takes for the number of coronavirus cases to double. Whereas at the beginning this period was 10 days, now it is more than one month. There can be only one conclusion – the restrictive measures are working, Prof. Kantardzhiev said.
