Virus cases surging among the young, endangering the elderly

ST. PETERSBURG, Fla.

Last week, more than 8,000 new cases were reported in that age group, compared with about 2,000 among people 55 to 64 years old. And experts say the phenomenon cannot be explained away as simply the result of more testing.

Elected officials such as Florida's governor have argued against reimposing restrictions, saying many of the newly infected are young and otherwise healthy. But younger people, too, face the possibility of severe infection and death. And authorities worry that older, more vulnerable...
