The number of daily coronavirus cases in Brazil has been increasing since last month, and the country's healthcare system is on the verge of collapsing.
Data compiled by Johns Hopkins University in the United States show Brazil's daily tally stood at more than 90,000, as of Saturday.
The country also now has the highest number of daily deaths in the world. On Friday 3,650 were reported, and 3,438 people died on Saturday.
A Brazilian research institute says more than 90 percent of the intense care units are occupied in more than half of the country's states and the capital Brasilia.
Brazilian President Jair Bolsonaro has been reluctant to implement measures against the pandemic nationwide. He has instead made maintaining economic activities his priority. Some states have introduced their own preventive measures, but they are not being fully observed.
Brazil had vaccinated only 1.9 percent of its population as of Saturday.
Experts warn that the country's healthcare system is on the verge of collapsing. They estimate that coronavirus deaths will reach 500,000 in July. They also say Brazil's death toll could eventually top the United States'.
