FIND and The Global Fund are co-conveners of the Access to COVID-19 Tools (ACT) Accelerator Diagnostics Pillar. The ACT-Accelerator is a ground-breaking global collaboration to accelerate the development, production, and equitable access to COVID-19 tests, treatments, and vaccines. On 28 July, the global health community commemorates World Hepatitis Day – an important opportunity to highlight and accelerate efforts to find the 290 million people who are unaware they are living with viral hepatitis. Each year, million lives are lost to hepatitis B and C.
