The pattern of the SARS-CoV-2 incidence concentrated in the 30-50N latitude zone suggests dust carrying the virus is spread by a circum-global jet-stream, specifically the northern sub-tropical jet-stream that blows in the high-altitude troposphere over northern China in early spring-time. It is known that the agent of the Kawasaki disease is carried by long-range winds to Japan and California from north-east China. We hypothesize that dust carrying the virus SARS-CoV-2 was similarly transported from the huge virus reservoir generated in Wuhan province to southern USA, thence across the Atlantic to Portugal and further states to the east. On this model the primary in fall of the dust/virus-carrier depends on the jet-stream interaction with regional weather systems, causing incidence of SARS-CoV-2 cases in various countries/ states along this latitude belt. The notable case of Brazil on 31 March 2020-exceptionally outside the 30-50N belt-is proposed to be due to the Azores cyclonic system entraining part of the jet-stream west of Portugal into the south-westerly trade winds, when these winds penetrate to Brazil during spring-time.
