- Abstract
This article discusses different-scale cycles of solar activity, from 11-year to quasi-millennial, and the manifestation of their combinatorics in epidemiological dynamics. It is shown that a significant change in the dynamics of the number of infectious diseases during an 11-year cycle is associated with solar activity, and not with its geophysical manifestations. Covid-19 pandemic paradoxes to began under conditions of a simultaneous minimum of 11-year solar activity (SA) and a minimum of the quasi-secular solar cycle are considered. It is assumed that under the conditions of the global SA minimum, genetic population characteristics played a decisive role in the development of local coronavirus epidemics, and also played a significant role in the effectiveness of mass vaccination in various countries. The highest relative mortality was observed in haplogroup R1b (values 20–35) versus values 5–8 in haplogroup R1a, and values 2–4 in haplogroup N. Vaccination efficiency is also maximum in haplogroup R1b. The estimated height of the cycles during which viral pandemics can develop both at the maximum and at the minimum of 11-year SA cycles fluctuates around the value of 100–110 average annual Wolf numbers. Basically, this binary phenomenon is observed in the phase of growth and decline of the SA quasi-centennial cycle. Under conditions of a long global minimum of solar activity with a cycle amplitude of 90 to 120, a doubling of the number of viral pandemics can be observed, with a significant contribution of the genetic characteristics of the population to the dynamics of local epidemics.
