If we believe billionaire philanthropist Bill Gates, very few countries will get 'A-grade' for new coronavirus response when it comes to understanding the scale of the damage Covid-19 could do.
Speaking to BBC, Gates said several countries have failed on providing proper healthcare and there will be a "post-mortem" when the disease is tackled.
"We are in uncharted territory due to a lack of investment and preparation for such a pandemic," Gates said.
