With regard to “The Covid Storm: A Pandemic Was Inevitable. Why Was No One Ready?” (Page One, Aug. 14), public health is as much about engineering as it is medicine. With this in mind, I have the following questions:Why did so many societies have to scramble to address sanitation and ventilation issues in health-care facilities and workplaces? Why were so many people still engaging in business travel when the meetings could be conducted online? Why were so many public schools and universities not prepared to convert to distance learning?
