[Question] Effective donations for COVID-19 in India

COVID-19 cases are rising pretty rapidly in India, and health capacity is struggling, with shortages of oxygen and hospital beds. There have been lists like this and this of fundraisers/​charities to donate to. Does anyone know about potentially cost-effective organizations that are currently working on mitigating the effects of COVID-19 in India, or, more generally, the kinds of things that donors should aim to give money to?
