Oxfam has called for a £130bn package from world governments to prevent millions of coronavirus deaths in poorer countries.
The charity has set out a five-point plan for help needed in nations such as Mali, where there are just three ventilators for one million people, and Zambia, where each doctor looks after around 10,000 people.
They are calling for investment in disease prevention including public health campaigns, as well as 10 million new health workers, as part of a package of debt cancellation and aid.
The charity also says all healthcare must be free and all private health facilities must be put back into the hands of governments ready for all treatment to be available free of charge.
Danny Sriskandarajah, chief executive of Oxfam GB, said: "For millions of people in refugee camps without clean water, and in countries with little or no health facilities, the impact could be catastrophic."
