A disease can be blamed for crippling an economy if it causes such a large number of people to die or to be hospitalised that the economy can no longer function because of absenteeism and death.
However in the case of Covid-19 the disease is so minor that only a very small proportion of those infected end up with serious symptoms.
The reason why the world is in a mess and economies are crippled is because the 99 % who are perfectly well have been prevented from working by their own governments just because a small number are sick.
