As Ferrari became the first team to launch their 2020 car on Tuesday night, in an opulent opera house near their Maranello base, the season itself was falling deeper into turmoil, with two of the first four races at ­serious risk of cancellation due to the spread of coronavirus. The scrapping of April’s Chinese Grand Prix could be confirmed ­on Wednesday, while the inaugural race in Vietnam, scheduled two weeks ­earlier, also finds its place on the calendar in danger. Given the scale of the epidemic in China, with more than 42,000 confirmed cases of coronavirus and over 1,000 deaths, it is all but ­impossible to see how the country can host a global sports event in just nine weeks’ time.
