“The virus needs some time to start spreading in one region or another,” Pokrovsky said in an interview with Sputnik radio.

According to him, “at first there was a strong increase in the incidence in Moscow, then a slight decrease in the number of new cases, while a steady increase continues in the rest of Russia.”

The expert stressed that such a situation is "a completely natural phenomenon."

“Usually, fewer examinations are done on Saturday and Sunday, as these are days off and many sick people are delaying the examination,” Pokrovsky added.

He clarified that "technically, the rise in the incidence in the middle of the week, when the results of examinations carried out on Monday and Tuesday come in."

As noted, "these factors are superimposed, and therefore the impression of jumps in incidence is created."
