Brazil’s Covid Crisis Is a Warning to the Whole World, Scientists Say

Brazil is seeing a record number of deaths, and the spread of a more contagious coronavirus variant that may cause reinfection.

RIO DE JANEIRO — Covid-19 has already left a trail of death and despair in Brazil, one of the worst in the world. Now, a year into the pandemic, the country is setting another wrenching record.

No other nation that experienced such a major outbreak is still grappling with record-setting death tolls and a health care system on the brink of collapse. Many other hard-hit nations are, instead, taking tentative steps toward a semblance of normalcy.

But Brazil is battling a more contagious variant that has trampled one major city and is spreading to others, even as Brazilians toss away precautionary measures that could keep them safe.

On Tuesday, Brazil recorded more than 1,700 Covid-19 deaths, the highest single-day toll of the pandemic.

......... 

Preliminary studies suggest that the variant that swept through the city of Manaus is not only more contagious, but it also appears able to infect some people who have already recovered from other versions of the virus. And the variant has slipped Brazil’s borders, showing up in two dozen other countries and in small numbers in the United States.

Although trials of a number of vaccines indicate they can protect against severe illness even when they do not prevent infection with the variant, most of the world has not been inoculated. That means even people who had recovered and thought they were safe for now might still be at risk, and that world leaders might, once again, be lifting restrictions too soon.

...........

That danger of new variants has not been lost on scientists around the world. Rochelle Walensky, the director of the U.S. Centers for Disease Control and Prevention, pleaded with Americans this week not to let their guards down. “Please hear me clearly,” she said. “At this level of cases with variants spreading, we stand to completely lose the hard-earned ground we’ve gained.”

KEY POINTS

• CDC Director Dr. Rochelle Walensky said she is “really worried” about states rolling back Covid-19 restrictions as cases appear to be leveling off at a “very high number.”
• “Please hear me clearly: At this level of cases with variants spreading, we stand to completely lose the hard-earned ground we have gained,” she said.
