Just this week Cuba has sent doctors and nurses to Honduras and Qatar to fight the global pandemic.

After sending medical professionals to 19 countries in a short period of time, Cuba stood out as one of the few countries to lead the global fight against the novel coronavirus.

Qatar on Wednesday became the latest country the Caribbean nation has extended help after Cuban doctors and nurses arrived in the Gulf nation.

While tiny, poor Cuba has sent medical teams to 19 countries, the U.S. has sent medical teams to...(checks notes)...no one.
The U.S. has instead went with the strategy of pressuring countries to reject help from Cuban doctors. A strategy that obviously is not working.
One place that the strategy has succeeded is in Brazil.

As the number of deaths caused by Covid-19 rose to nearly 2,500 on Sunday, Jair Bolsonaro left his presidential palace in Brazil’s capital, Brasília, to fraternize with flag-waving radicals.

Among the demands their banners listed were an end to the social distancing measures opposed by Bolsonaro, the closure of Brazil’s congress and supreme court, and a re-run of a dictatorship-era decree used by military rulers in the late 1960s to suffocate their political opponents.

“The era of roguery is over. Now it’s the people who are in power,” Bolsonaro proclaimed outside the Brazilian army headquarters, coughing repeatedly as he spoke.
...Even members of the military top brass were reportedly upset, with one senior official urging citizens to ignore Bolsonaro’s actions. “Let the president talk to the nutters on his lonesome,” they told the news magazine Veja.

Bolsonaro, who smeared the Cuban doctors in Brazil as a nefarious fifth column, denigrated them as “terrorists,” and expelled them, has since reversed this policy.
However it appears that this was done too late.

Researchers at a group of respected Brazilian universities and institutes said last week there were probably close to 12 times more cases of coronavirus than were being officially reported by the government in Latin America’s largest country, home to some 211m people. As of Sunday, Brazil had more than 38,000 confirmed cases, which would put the true tally at 456,000.

“The rapid course of the pandemic and the low number of tests performed in Brazil make it difficult to estimate the actual number of confirmed cases,” the Health Operations and Intelligence Nucleus, or NOIS, said.

The corrupt, U.S.-backed coup government in Honduras, that systematically gutted its health care system, and called out the military to violently suppress its own doctors and nurses, was also a U.S. success story until this week.
Fortunately the U.S. news media is always there to set the record straight.

A March Bloomberg opinion article (3/23/20) headlined “Coronavirus Could Give Cuba’s Flying Doctors New Wings,” for example, came equipped with the following caveat in the subheadline: “But allowing Havana to exploit the virus for hard currency will just empower repression at home.”

Yes, Cuba is "exploiting the virus" by saving people's lives, but America is above those sorts of things.
