 Brazil’s brutal surge in COVID-19 deaths will soon surpass the worst of a record January wave in the United States, scientists forecast, with fatalities climbing for the first time above 4,000 in a day as the outbreak overwhelms hospitals.
 
 "It’s a nuclear reactor that has set off a chain reaction and is out of control. It’s a biological Fukushima," said Miguel Nicolelis, a Brazilian doctor and professor at Duke University, who is closely tracking the virus.
 
 U.S. President Joe Biden moved up the COVID-19 vaccine eligibility target for all American adults to April 19, but warned that with new virus variants spreading “we’re still in a life-and-death race.”
 
 One in three COVID-19 survivors in a study of more than 230,000 mostly American patients were diagnosed with a brain or psychiatric disorder within six months, suggesting the pandemic could lead to a wave of mental and neurological problems, scientists say.
