Increasing Pollen Rates Affect COVID Infection Rates

Columbia :A new study found that pollen-which is also being affected by climate change---can help explain additional COVID infection rates during the Spring when tree allergies become dominant.  How much of an impact?  Based on these data, an increase of pollen abundance by 100 grains per cubic meter of air resulted in an average increase in infection rates of 4 percent. The results are published in PNAS titled "Higher Airborne Pollen Concentrations Correlated with Increased SARS-CoV-2 Infection Rates."

Climate change would be responsible for two thirds of pollen increase in Europe

Vienna: Climate change would be responsible for two thirds of this increase, the remaining third would be due to the colonization of the plant as a result of human activities. These estimates, made by a European team of researchers, show that it is now necessary to establish coordinated management of this invasive plant in Europe followed by long-term pollen and mapping the presence of plants. These estimates are published in the journal Nature Climate Change May 25, 2015.

Pollen levels average, symptoms dependent on the weather

Vienna: Nature has awoken from her winter sleep. The changeable weather means that the season has got off to a quiet start. Birch pollen, however, is almost due to be released and all predictions are that the levels will be average. Caveat: if the season starts suddenly, however, the symptoms experienced by sufferers can nevertheless be very severe.
