Murthy said the issue was “personal” for him, since he once lost an uncle to a severe asthma attack. “We have more people exposed to triggers that can cause asthma attacks, and more asthma attacks mean more days of school missed. They mean more days of work missed. They mean more costly trips to the doctor,” Murthy said. “And they most importantly mean more scary moments for parents and for children.” In a background call with reporters ahead of the event, administration officials identified the elderly, children, minorities, the sick and low-income individuals as being at particularly high risk levels for injuries caused by extreme weather.
