‘Extremely Ill’In Houston, where hospitals have been strained by the influx of patients, many young people are in intensive care, David Persse, the city’s director of emergency medical services, said during a media briefing Monday.“They are extremely ill," Persse said. “If they’re thinking, ‘I’ll get sick and then I’ll get over it,’ recognize that 15% of the people in ICUs now are in their 20s and 30s."Simran Bal, a 23-year-old Chicago resident, fears the only way some of her peers will get the message is if a close friend gets severely ill.“It’s pretty disheartening to say that I feel like extreme measures are the only way people are going to get the idea," said Bal, who has to navigate crowded pubs when she picks up orders for Door.
