Look at the Statista graph based on OECD data.
The public health expenditure (the total amount spent on healthcare by central / federal, state / provincial and city / local governments combined) in USA is more than one-sixth of the country’s GDP, yet this country with less than 4.25% of the world’s population has 24.6% of the world’s COVID-19 Coronavirus patients.
France, which spends almost one-ninth of its GDP on health, has less than 0.84% of the world’s population and 8.08% of the world’s Coronavirus cases.
Germany, which spends almost one-ninth of its GDP on health, has 1.075% of the world’s population and 7.29% of Coronavirus cases.
UK, which spends almost one-tenth of its GDP on health, has 0.87% of the world’s population and 3.39% of Coronavirus cases.
Spain, which spends 8.9% of its GDP on health, has just 0.6% of the world’s population and 11.06% of Coronavirus cases.
Italy, which spends 8.8% of its GDP on health, has 0.776% of the world’s population and 10.63% of Coronavirus cases.
In Contrast, India, which spends just 1.28% of its GDP on health, has 17.7% of the world’s population and 0.285% of Coronavirus cases. Is it because testing for the COVID-19 infection has been very low in India or is it because, due to low health expenditure (both public and private), Indians have developed stronger immunity to almost every disease?
