The Dhaka Tribune reports on IPA's study of more than 340,000 people across 600 villages in Bangladesh that demonstrated the effectiveness of masks—particularly surgical masks—in preventing the spread of COVID-19. The findings of this evaluation, the largest of its kind, may help inform the COVID response across Asia, Africa, and Latin America.

The study was also featured in Nature (twice), Salon, Yale Daily News, Yale Insights, Stanford Medicine, Gizmodo, New York Daily News, Live Science, Washington Examiner, Daily Mail, India Today, BD News 24 (Bangladesh), Daily Star (Bangladesh), and more.
