Hello,
To reduce the spread of coronavirus in Bangladesh, ICDDR,B- International Centre for Diarrhoeal Disease Research, Bangladesh has invented soapy water for the low-income people in South Asia.
soapy water - a simple mixture of 30g of powdered detergent in any 1.5L recyclable bottle - is a low-cost alternative.
