The month of October 2020 has already started and presents a mixed bag of good and bad news...the good being the reduction of new cases of COVID-19 in Africa, while the bad news is the rising cases in the northern hemisphere, including Europe. These changing epidemiological patterns seem to correspond with the advent of the winter season. It doesn’t take a genius to notice the association between changing weather patterns aka sunshine and vitamin D levels with the changing incidence and prevalence of COVID-19 cases. One may ask, what does this have to do with agrochemicals? Synthetic agrochemicals interfere with the immune system and increase vulnerability to COVID-19.
