International audience The novel COVID-19 disease is a contagious acute respiratory infectious disease whose causative agenthas been demonstrated to be a new virus of the coronavirus family, SARS-CoV-2. Alike with other coro-naviruses, some studies show a COVID-19 neurotropism, inducing de-myelination lesions as encounteredin Guillain-Barré syndrome.In particular, an Italian report concluded that there is a significant vitamin D deficiency in COVID-19infected patients.In the current study, we applied a Pearson correlation test to public health as well as weather data, inorder to assess the linear relationship between COVID-19 mortality rate and the sunlight exposure. Forinstance in continental metropolitan France, average annual sunlight hours are significantly (for a p-valueof 1.532 × 10−32) correlated to the COVID-19 mortality rate, with a Pearson coefficient of -0.636.This correlation hints at a protective effect of sunlight exposure against COVID-19 mortality. This paperis proposed to foster academic discussion and its hypotheses and conclusions need to be confirmed byfurther research. La nouvelle infection au COVID-19 est une maladie respiratoire infectieuse sévère dont l'agent causal a été identifié comme un nouveau virus de la famille des coronavirus, SARS-CoV-2. Comme les autres coronavirus, des études montrent un neurotropisme du COVID-19, induisant des lésions démyélinisantes comme dans le syndrome de Guillain-Barré.Plus particulièrement, une note italienne conclue qu'il y a un déficit significatif en vitamine D chez les patients infectés par le COVID-19.Dans cette étude, nous avons utilisé un test de corrélation de Pearson sur des données de santé publique et météorologiques, dans le but de statuer sur une possible relation entre l'ensoleillement et la mortalité induite par le COVID-19. Pa exemple dans la France métropolitaine continentale, la moyenne des heures d'ensoleillement est significativement (pour une p-value de 1.532 × 10−32) corrélée au taux de mortalité due au COVID-19, avec un coefficient de Pearson de −0.636.Cette corrélation établit un effet protecteur de l'ensoleillement contre la mortalité due au COVID-19. Ce manuscrit est proposé uniquement pour une discussion académique et les hypothèses et ses conclusions doivent être confirmées par d'autres recherches.
