“We already know that this is an extremely persistent virus that we have to learn to live with,” Dobrin Vassilev, head of the cardiology clinic at Alexandrovska University Hospital, told NOVA about kovid-19.

“In Bulgaria, non-compliance with measures. The percentage of compliance in Europe is much higher than in the United States. In practice, the spread of infection is directly proportional to the degree of compliance with measures that are not so severe and unbearable for society. Personally, I have no explanation for myself why people don’t want to go back to a relatively normal life with a slight modification such as wearing masks, keeping their distance and good hand hygiene, “he said. Associate Professor Vassilev.

Four classes from a quarantined Sofia school

“In Europe, an average of 75% of people wear masks. In the United States, about 25%. According to my observations in Sofia, between 30 and 40% of people wear masks, and outside the capital they are less than 10%, “said associate professor Vassilev.

“The number of patients with covid-19 is not decreasing. This can be seen in the statistics. We have been on the same plateau for about a month and we saw the true hidden morbidity that was circulating in society at the time that children entered the School. Children and teachers have not been infected since the schools opened. They were infected 2-3 weeks ago, “stressed Assistant Professor Vassilev.

“In the next few years, the virus will have it. If someone has the illusion that kovid-19 will disappear with a magic wand in a month, two, three, the chief epidemiologist of Germany is already talking about a horizon until 2023. No we will learn the easy or difficult way to live with the virus. “

“People with cardiovascular disease are one of the groups at highest risk for COVID-19. There is a direct involvement of the cells of the heart muscle, as well as all the vascular cells in the lungs, peripheral vessels and even the brain. virus can become trapped and multiply in these vessels and predisposes to many thromboses “, explained Prof. Assoc. Vassilev.

He noted that the causes of death from covid-19 vary slightly from one country to another, indicating that certain genotypes are more vulnerable to one or another aspect of the disease.

“The vaccine is a likely solution, but no one should expect it to completely solve the problem, because its expected effectiveness is between 60 and 70 percent,” Associate Professor Vassilev said.

He pointed out that the so-called herd immunity is only a possibility and so far there is no clarity about its mechanism of occurrence. The data so far shows that there is no herd immunity to this coronavirus.
