Amidst many Brazilians still partying, an official warned that "there are no ICU beds for everyone's parents, aunts, sons, or girlfriends".

The person who issued the warning was Fernando Maximo, head of the state health department of Rondonia, one of the heavily influenced Covid-19 sites in Brazil.

Bahia Governor Rui Costa, meanwhile, said "Brazil will be in chaos in two weeks."

Much of the world is taking measures to limit or promote Covid-19 vaccination to control the pandemic, but the situation in Brazil is getting worse than ever.

The hospital bed utilization rate is also hitting the highest threshold.

From the very beginning of the pandemic, the Brazilian situation was more serious than it was in most of the world.

More than 250,000 Brazilians died of Covid-19, making the country the second deadliest in the world after the United States.

"With this situation, if there is no action, by March people will be fighting for both the hospital bed and the grave in the cemetery. We will need to open a new cemetery to bury the bodies," says Domingos Alves, expert.

Health analysts warn that the Brazilian pandemic is at risk of having a significant global impact.

"If Brazil does not control the virus, it will become the largest laboratory for nCoV strains in the world," said Miguel Nicolelis, an epidemiologist at Duke University in the US.

Brazil is the hometown of Nicolelis.

"This is the first time in Brazilian history that two-thirds of the health systems in the capitals will collapse at the same time. I don't mean Manaus, it's Sao Paulo, the most prosperous city in the Southern Hemisphere.

Nicolelis and Alves both called for an immediate three-week nationwide blockade to avoid a humanitarian disaster.

However, a concerted nationwide effort to contain the virus seems impossible.

"They can be harmful to children. Masks side effects are starting to appear," Bolsonaro said last week, adding that side effects include anger, headaches and difficulty concentrating.

Some cities have imposed new restrictions, such as curfew in Brasilia and ask for uncomfortable businesses at Porto Alegre.

Brazil's unemployment rate is at its peak and millions of people are being pushed into poverty.

Ligia Bahia, a professor of public health at the Federal University of Rio de Janeiro, said that the tragedy of Brazil was the result of doubt over argument, politics over science.

Bahia judged that the Brazilian government and people still had time to act.

However, Bahia is still worried about the prospect in the coming weeks.
