Brazil’s coronavirus catastrophe has deepened further after more than 4,000 daily deaths were reported for the first time since the outbreak began in February last year.

At least 4,195 people were reported to have lost their lives on Tuesday, taking Brazil’s total death toll – the world’s second highest after the US – to nearly 337,000.

Brazil also reported 86,979 new infections. Experts fear a record 100,000 Brazilians could lose their lives this month alone if nothing is done.

“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 in the US, who is closely tracking the virus.
