COVID-19 is having a catastrophic impact on the most vulnerable communities around the world and is threatening decades of progress in the fight against HIV, TB and malaria. The Global Fund works with partners, countries and communities to fight COVID-19, adapt lifesaving HIV, TB and malaria programs, and reinforce fragile systems for health. Through our COVID-19 Response Mechanism (C19RM ), the Global Fund is now the primary channel for providing grant support to low- and middle-income countries for COVID-19 tests, treatments (including medical oxygen), personal protective equipment (PPE) and critical elements of health system strengthening.
