In A Family Guide to Covid, William A. Haseltine answers tough questions about Covid-19 honestly, with equal measures of clarity and compassion.

A new disease has spread across our world. Schools have shut down, people around the world have been asked to stay home, businesses are shuttered, economies are crashing.

The sad state of affairs is not entirely new for Dr. Haseltine who remembers how polio overshadowed his young life. As he got older, he realized that diseases didn’t just harm individuals, they crippled communities and devastated entire countries. He became a scientist, dedicating his life to understanding the diseases that threaten us most and figuring out ways to stop and prevent them.
