“…Nasirpour, et al (2021), based on an autoregressive statistical analysis of past pandemics since 1918, indicated the development of new solar cycles until 2100 and new virus mutations mainly in tropical zones due to variations in sunspot extremes. Ragulskaya and Tekutskaya (2021) found that variations in solar activity and the occurrence of pandemics for 1880-2021 show that all in uenza pandemics of the 20th century occur at the peaks of 11-year solar cycles. Typhus pandemic 1847-1848, 1899, and civil war 1918-1919 also occurred during the period of maximum solar activity.…”

“…Over the past 70 years, the maximum intensity of galactic cosmic rays (GCR) was recorded in 2008-2010 and 2019-2020 (Ragulskaya, Tekutskaya 2021). According to the authors, the emergence of new strains of in uenza and coronavirus viruses over the past 11 years is associated with a decrease in the ozone layer, an increase in UV radiation, and an increase in galactic cosmic rays during solar minima of the 23 d and 24th solar cycles.…”

The concept of planetary boundaries defines nine areas mostly affected on Earth health. One of these areas connected with the ozone layer state is responsible for ultraviolet (UV) flow reaching Earth’s surface. There is a close relationship between solar activity and geomagnetic indices and changes in polar ozone under the influence of solar radiation. This work discusses the relationship between the geomagnetic index Ap, the total ozone content as secondary indicators of solar activity, and the incidence of COVID around the world for the period from January 1, 2020, to May 1, 2021, when there were the first and second waves of the incidence of the virus. Obtained comparative analysis of geomagnetic index Ap and TO in the last solar cycle reveals that geophysical variations can foster favorable conditions for pandemics. The 25th solar cycle's peak in 2024 aligns with the onset of the COVID-19 pandemic, consistent with previous research. Increased GCR and UV radiation during solar cycle minima further influence Earth's conditions. The pandemic coincided with heightened solar activity after the 24th cycle's minimum and the secular maximum of GCR. Geomagnetic disturbances and reduced TO levels in both hemispheres exacerbated the COVID-19 waves, accelerating case development.

“…Космическая погода и солнечная активность (СА) влияют на мутации и изменчивость вирусов, а также повышают вариабельность и адаптационную устойчивость человеческой популяции. В максимуме СА существенным оказывается вклад вариаций геомагнитного поля, вариаций ультрафиолетового излучения Солнца и солнечных космических лучей, а в минимуме на роль основного регуляторного биотропного фактора претендуют галактические космические лучи [1,2]. Большинство вирусных пандемий происходят в экстремумах солнечной активности, в зависимости от соотношения фаз 11-летнего цикла и цикла Гляйсберга.…”

The development of large-scale pandemics from local epidemics is characteristic of high maxima of the 11-year solar activity (SA) cycle. During lower cycles of solar activity (with a height of about 100-110 average annual Wolf numbers), the development of pandemics is observed both at the maxima and minima of the 11-year cycle of solar activity.The COVID-19 pandemic was started at the lows of the 11-year and quasi-secular solar cycle. Space weather and solar activity, together with the genetic composition of the population, determined the development of local coronavirus epidemics under the conditions of the global minimum of solar activity. Their contribution is more than 500% against 20-30% accounted for by other factors (except for vaccination), such as the average age of the population, lockdowns, isolation of patients, weather conditions, and the level of medicine. The COVID-19 pandemic is most severe in countries with a dominant R1b haplogroup. The effectiveness of mass vaccination depends on the genetic composition of the population too. The maximum decrease in relative mortality after mass vaccination of the population is observed in countries with a haplogroup R1b (a 10-fold decrease). However, in countries with a haplogroup N, relative mortality increased by 4 times. Steady self-oscillatory waves of incidence and mortality have been formed due to mass vaccination and lockdowns by 2022. The effect of vaccination decreases with increasing solar activity. The influence of these multidirectional processes on coronavirus pandemic at the maximum of the 25th cycle of solar activity requires further study.
