The SARS Corona Virus-2 originated in Wuhan, China and caused the disease classified by WHO as COVID-19. The virus has spread from China to the rest of the World. This paper analyses the differential speed of spread of the virus from China to different countries, i.e. it analyses the determinants of the inter-country transmission of the virus. Part two of the paper will analyze the determinants of the speed of spread within a country, i.e. the intra-country spread of the virus. Part III will examine the determinants of deaths and eventual Departure.
