Pulmonologist Babak compared the combination of COVID-19 and lung diseases with an “atomic bomb” 
Pulmonologist Sergey Babak and lung diseases with the “atomic bomb” that explodes in the human body. He told about this in an interview with radio Sputnik.
Babak explained that the coronavirus primarily affects the lungs, and if the virus is superimposed on other serious diseases of this organ, then the danger increases many times over. He noted that there is such a disease as idiopathic pulmonary fibrosis (IPF), which manifests itself in people aged 70 and older, in which the lungs “shrink”. Against the background of coronavirus infection, the same processes occur in the lungs, the pulmonologist added. It is noted that the risk of developing this disease increases with smoking.
In addition, the doctor said that there is still chronic obstructive pulmonary disease, which also manifests itself in smokers. He noted that the combination of these diseases with COVID-19 is comparable to an explosion in the human body.
Earlier, Alexei Agranovsky, professor of the Department of Virology, Faculty of Biology, Moscow State University, admitted that a strain of coronavirus may appear in Russia, which will have the ability to escape from existing vaccines. The virologist noted that a new variant could arise in any country where there are many cases of COVID-19 infection. He stressed that it is very difficult to predict the properties of such a strain. For example, it can be a strain that is leaving vaccines, the expert explained. At the same time, Agranovsky noted that the delta strain of the virus still dominates, which creates an obstacle to the emergence of new variants.
