With limited sanitation and little space, millions of people living cheek by jowl in slums cannot take even the most basic hand-washing and social distancing precautions recommended by health authorities.
"We are increasingly concerned about the poor and other vulnerable groups more at risk from disease and death from the virus," Pan American Health Organization chief Carissa Etienne said this week.
With infections continuing to climb in the pandemic's new epicenter Brazil, as well as Peru and Chile, experts warn the situation is rapidly worsening.
In a region where an estimated 54 percent are employed in the informal sector, slum residents are forced to choose between "starving or dying from the virus," according to Brazilian economist Dalia Maimon of the Federal University of Rio de Janeiro.
Maimon sums up the prevailing belief as: "if dying of hunger is a certainty, by not working -- then I will take the risk of trying not to become infected by going out to work."
An economic crisis exacerbated by the shutdown has left millions of Latin Americans without a livelihood. In Brazil alone, five million people lost their jobs since the pandemic began, the government said Thursday.
- 'Staying home means starving' -
"We are construction workers, people who sell things, people who go out every day. With confinement everything has changed for most of us. We find ourselves without any work," Oscar Gonzalez, 43, told AFP.
Gonzalez, a welder in the deprived Brisas del Sol area of Santiago, was employed in a workshop that closed down last month.
The neighborhood has seen an increase in social unrest this week as people took to the streets and erected barricades to demand state aid.
"We don't even get a little help from the government here. They believe that we can live without money. But how can we buy food?" Gonzalez asked.
It is a sentiment heard also in Santiago's sprawling La Pintana area, where locals lambast the state's slow reaction to the crisis.
"If we don't support each other, nobody helps us here," says Gloria Reyes, a 62-year-old seamstress who now runs a soup kitchen.
The virus "has stopped everything," said Claudia Gutierrez, 31, who runs a market stall selling second-hand clothes.
- Soup kitchens -
"I'm 55 years old, my family is from here and I have never seen so many soup kitchens in my life," said the La Pintana's mayor Claudia Pizarro, a member of the leftist opposition Democratic Party.
"Last week it was 20, and this week it's 40," she said.
La Pintana has more than 2,100 COVID-19 cases and "more than 50 percent of the PCR tests we are doing are positive," said the mayor, well above the 12-16 percent positives seen nationwide.
Fifteen people with COVID-19 died in the area, according to Pizarro.
In Sao Paulo, Brazil's sprawling megacity of 12.2 million, the coronavirus has killed more than 6,400 people of the 86,000 officially infected.
After the United States, Brazil is the country most affected by the pandemic in terms of numbers, with more than 25,000 deaths and 410,000 infections out of a population of 210 million.
"We must have our own public policies and create alternatives because of the absence of the government," said Gilson Rodrigues, an official in Paraisopolis, the second largest favela in Sao Paulo.
"We have to prepare for the worst-case scenario."
In Argentina, a spike in cases in a Buenos Aires slum last week forced the government to postpone plans to emerge from a 10-week lockdown.
On Monday another surge in the Villa Azul slum spread further alarm, and police enforced quarantine, as authorities fear the virus could spread to a much bigger slum nearby.
- Absent state -
Elsewhere, the absence of the state -- a vacuum that existed even before the pandemic -- has led to criminal organizations moving in to extend their control by helping stricken communities.
The ability of these groups to fill the void left by the authorities "is the most alarming trend" since the virus struck, security expert Douglas Farah told a recent forum in Washington hosted by the Organization of American States.
In Mexico, cartels are distributing food and medicine; in Honduras, gangs organize vehicle disinfection campaigns, to protect themselves from the virus in the areas they control.
According to the UN, nearly 89 million people in the region do not have even basic sanitation services, making impossible regular hand-washing, the most basic protection against the coronavirus.
In Peru almost a third of Lima's 10 million population are facing serious water supply problems.
"The water crisis in Lima is a silent threat. The most vulnerable populations are those most at risk of being exposed to the pandemic," Mariella Sanchez, head of the Aquafondo NGO, told AFP.
Shortages of electricity and gasoline have added to the lack of water in Venezuela.
In the town of San Cristobal on Colombian border, Reinaldo Vega's family collects water in buckets from a pipeline in the street and uses what he terms "boy scout" techniques to get through.
"This is how we survive," he told AFP, as he went off to forage for firewood to cook.
