论文摘要
太阳紫外线$ - $ C光子没有到达地球表面，但已知具有对病毒有效的杀菌特性。较柔软的UV $ - $ B和UV $ - $ $ $的光子（毫无疑问地到达地球表面）对病毒的影响很少，尤其是在单个$ - $ - $绞合的RNA病毒上。在这里，我们结合了对紫外线，太阳照射测量，太阳照射测量在SARS $ - $ -COV $ -2 PANDEMICS，全球记录的COVID $ -19死亡率数据和我们的“ Solar $ - $ pump'$ upper'$ $ $ $ $ $ $/单个$ - $固定的RNA病毒covid $ - $ 19和（b）在夏季中午到达地球温带地区的太阳辐射足以使63 \ perc在开放式$ - $ - $ - $ - $ - $ - $ - $ - $ - $ - 1.5 x 103 TCID50 $/$ ML，比典型的Aerosol中更高）。我们得出的结论是，在整个暴发的扩散中，SARS $ - $ 2 $ - $ 2 $ - $ 2 $ - $ 2 $ - $ 2 $ - $ - $ - $ - $ - $ - $ - $ - $ - $ - $ - $ - $ - $ - $ - $ - $ - $ - $ - $ - $ - $ - $ - $ - $ - $ - $ - $ - $ - $ - $ - $ - $ - $ - $ - $ - $ - $ - $ - $ - $ - $ - $ - $ $ $串联的爆发（温带区域都表现出明显的季节趋势和赤道区域的痛苦，平均而言，$/$ $/$ $/$/$ $/$ $/$ $ $ $ b $ b $ b $ b的差异可能有效地设置。 年。我们的结果表明，太阳能UV $ - $ b $/$ a在计划限制流行病的策略中起重要作用，该策略应在春季$/$夏季的月份进行制定并设置，并在低$ -URAR $ - $ - $ $ - $ iraradiation期间完全实施。
Solar UV$-$C photons do not reach Earth's surface, but are known to be endowed with germicidal properties that are also effective on viruses. The effect of softer UV$-$B and UV$-$A photons, which copiously reach the Earth's surface, on viruses are instead little studied, particularly on single$-$stranded RNA viruses. Here we combine our measurements of the action spectrum of Covid$-$19 in response to UV light, Solar irradiation measurements on Earth during the SARS$-$CoV$-$2 pandemics, worldwide recorded Covid$-$19 mortality data and our 'Solar$-$Pump' diffusive model of epidemics to show that (a) UV$-$B$/$A photons have a powerful virucidal effect on the single$-$stranded RNA virus Covid$-$19 and that (b) the Solar radiation that reaches temperate regions of the Earth at noon during summers, is sufficient to inactivate 63\perc of virions in open$-$space concentrations (1.5 x 103 TCID50$/$mL, higher than typical aerosol) in less than 2 min. We conclude that the characteristic seasonality imprint displayed world$-$wide by the SARS$-$Cov$-$2 mortality time$-$series throughout the diffusion of the outbreak (with temperate regions showing clear seasonal trends and equatorial regions suffering, on average, a systematically lower mortality), might have been efficiently set by the different intensity of UV$-$B$/$A Solar radiation hitting different Earth's locations at different times of the year. Our results suggest that Solar UV$-$B$/$A play an important role in planning strategies of confinement of the epidemics, which should be worked out and set up during spring$/$summer months and fully implemented during low$-$solar$-$irradiation periods.
