"This book was written in New York City, by a public health physician working at the New York City Department of Health and Mental Hygiene and the assistant dean of career services at Columbia University Mailman School of Public Health, during a time period when our city's schools and theatres closed, ambulance sirens wailed day and night, and thousands of our fellow New Yorkers perished in a pandemic, something public health experts had been warning about for years"-- Provided by publisher.
