Abstract
ObjectiveWe address the hypothesis that the extraordinary sandstorm occurred on 22-24 February 2020 might have a role in the different cumulated incidence of COVID-19 cases between the islands of Tenerife and Gran Canaria, since it obliged to reduce significantly air traffic and forced to suspend all major carnival street events in all most locations. MethodWe performed a retrospective analysis of COVID-19 cases as to 1 April 2020 according to symptoms onset, weather-related data and Carnival events in Tenerife and Gran Canaria. ResultsThe sandstorm occurred on February 22-24, 2020, forced air traffic to close, reducing the influx of tourists to the Canary Islands and suspending carnival events in most places, except in Santa Cruz de Tenerife. Cumulated incidence as to 1 April was 132.81/100,000 in Tenerife, and 56.04/100,000 in Gran Canaria. ConclusionsThe suspension of Carnival events due to the sandstorm in the Canary Islands contributed to reduce differently the SARS-CoV-2 spread in Tenerife and Gran Canaria.
