"When exactly will we record an increase in coronavirus infections? One would have to rely on mathematical calculations. However, given the experience of the past year, I can say that travelling, returning from holidays will certainly be associated with infections, both of adults and children," she added.


According to the expert, tests after returning to the country and quarantine to a large extent will reduce the spread of infection, but do not fully eliminate it.


"There are times when a person may already be infected at the time of the test, the virus is hatching in their body, but there is still not enough of it to give a positive result,” she said.


Prof. Zajkowska pointed out that the increase in infections in the autumn period will also be favoured by the weather. "We will be spending more time indoors, where transmission of the virus is facilitated," she said.


She pointed out that the increase of infections will vary depending on the number of people vaccinated in a given region of Poland.


"You only have to look at the vaccination map to see that vaccination rates are higher in big cities than in rural areas. There are places in the east of the country where the saying “deficient” concerning the level of unvaccinated people is mild,” she added.


According to Prof. Zajkowska, the information campaign on vaccination against coronavirus does not bring the expected results.


"Awareness among patients is low, they are afraid of vaccination, and they get their knowledge about vaccination from what their friends say. This is of concern especially in at-risk individuals, which include those with chronic illnesses and undergoing oncological treatment,” she said. 


She added that "the idea of vaccination cannot be undermined because we can function in the population thanks to vaccination".


According to Prof. Zajkowska, the autumn wave of infections "should not be as large in Poland as last year's, because part of the population has already been vaccinated". She added that we should, however, prepare hospitals for possible admission of Sars-Cov2 infected patients. "Looking through last year’s experience, I believe that with fewer people infected, infectious disease wards operating in each hospital will work better than single-named hospitals. This will allow other patients to be treated, not just those infected with coronavirus," she said.
