Solar activity and COVID-19 pandemic
Maria Ragulskaya
Abstract
Abstract Solar activity (SA) dynamics increases mankind’s evolutionary adaptability to pandemics. Flu pandemics from 1880 to 2020 took place during maximum or minimum of solar cycles. The article discusses several factors that modulated the development of the COVID-19 pandemic: SA dynamic, genetic population features, environment temperature, the effect of lockdowns, and vaccination in various countries. The population genetic composition turned out to be the most significant factor for coronavirus mortalities during a SA global minimum 2019-2020. COVID-19 pandemic is most severe in countries with a dominant haplogroup R1b (the relative number of deaths per million is more than 12-25). Local COVID-19 epidemics were more easily in countries with a dominant haplogroup N (relative number of deaths less than 3). The incidence per million people in haplogroups R1b: R1a: N has a ratio of about 7: 2: 1. This ratio does not depend on the pandemic waves and the population vaccinated rate. Vaccination effectiveness may depend on the population’s genetic characteristics too. It is expected to maintain extremely low solar activity during the 30 years. Under these conditions, a twofold increase in the number of pandemics (every 5-6 years instead of 10-11 years) can be expected with pronounced genogeographic differences.
