As the curve for the COVID-19 pandemic flattens or falls in many parts of the world, the virus continues to surge across Latin America.

With 255,368 total coronavirus infections as of Monday evening, according to Johns Hopkins University, Brazil has now leapfrogged the United Kingdom as the country with the third-highest number of Covid-19 cases in the world. However, while these numbers are already frightening, Brazil has the lowest rate of coronavirus testing out of the ten countries with the most infections, suggesting the actual total may be far higher.

With its massive population of almost 210 million people, it should come as no surprise that Brazil is among the worst-affected countries in absolute numbers. Indeed, Brazil’s number of cases per 1 million inhabitants is lower than that of the United Kingdom or Italy, where more overall infections have been recorded. On Friday, Brazil’s Chief of Staff Walter Souza Braga Netto attempted to cash in on this data, sharing a crudely made chart on WhatsApp highlighting that the country’s Covid-19 deaths per capita are comparatively small.

This, however, masks the inconvenient truth that Brazil’s official Covid-19 figures do not tell the full story of the virus’ spread in the country.

As of Tuesday, there were 565,000 cases in Latin America and the Caribbean and more than 31,000 deaths, according to Johns Hopkins University of the US.

Carissa F. Etienne, director of the Pan American Health Organization (PAHO), warned that the virus is hitting poor and vulnerable groups, including indigenous communities in the Amazon region.

“We are increasingly worried about the poor and other vulnerable groups at greater risk of illness and death from the virus...This includes indigenous groups living in the Amazon basin, which is home to over 2,400 indigenous territories across eight countries. We have already confirmed 20,000 cases of COVID-19 in the provinces that form the Amazon basin,” said Etienne.

PAHO authorities said the contagion was rising in densely populated Amazon border cities such as Manaus in Brazil, Leticia in Colombia and Iquitos in Peru, but the greatest danger is the virus spreading to isolated villages.

With 262,545 cases, Brazil became number three in the world, surpassing the UK, which reported 250,121. Brazil sits behind Russia and the US in terms of the number of infections.

Brazil’s Health Ministry is under interim supervision from Gen. Eduardo Pazuello, who replaced Nelson Teich on April 15. Teich resigned after 28 days in the administration of President Jair Bolsonaro.

Teich's predecessor, Luiz Henrique Mandetta, said in an interview published Monday by the Folha de S.Paulo newspaper that Brazil still has some "hard" weeks ahead.

The second most affected country in the region in terms of cases is Peru, with 94,933 and 2,789 deaths.

Mexico follows with 51,633 infections and 5,332 deaths, and Chile has 49,579 cases and 509 deaths.

Colombia is struggling with an outbreak in Leticia, a city that borders Brazil. The country has 16,300 confirmed cases and 592 deaths.

El Salvador's Supreme Court suspended a state of emergency Monday that was declared by President Nayib Bukele because of the coronavirus.

Bukele extended restrictions Saturday in the Central American country without approval from Congress, which drew criticism from many who cited the unconstitutionality of the action.
