One cleaner at a state hospital, Don Alejandro, 70, told Amnesty in May that he had asked to be allowed to clean administrative areas instead of medical ones because he had a high risk of contracting the virus. His employer allowed him to move, but cut his income by 16 percent.
For its numbers, Amnesty used sources such as memorial pages, government figures, lists compiled by national medical associations, and lists and obituaries published in media globally. For the U.S. death count, researchers used a joint database from The Guardian and Kaiser Health News that specifically tracks deaths of the country’s health workers.
The Centers for Disease Control and Prevention, however, lists only 672 health worker deaths in the U.S. as of Thursday. The C.D.C. said that it was working with limited data.
