Pollen May Predict COVID-19 Season End


Researchers compared influenza and dusting schedules for 2016–2020, as well as COVID-19 in the Netherlands. And they concluded that the appearance of pollen in combination with data on solar activity can be a predictor of the seasonality of flu-like epidemics, including coronavirus.

The appearance of a large amount of pollen in the air can actually lead to the binding of microdrops containing the virus, which slows its spread, Oleg Batishchev, associate professor of the Department of Biophysics at Moscow Institute of Physics and Technology, told Izvestia.

“On the other hand, flowering begins at certain air temperatures and solar activity, which also affect the virus – high temperatures and ultraviolet light reduce the spread of viruses – so this can be a simple coincidence,” the expert noted.

The authors of the preprint themselves claim that, judging by their models, SARS-CoV-2, together with other viruses similar to the flu, may be more active in the season when the pollen season ends in the northern hemisphere – in autumn and winter.
