Scores of monkeys in Rio de Janeiro have been killed in an attempt to stop the spread of yellow fever.
Locals, mistakenly believing that the animals can spread yellow fever to humans, are blamed for the surge in killings.
Just this year, 238 monkeys have been found dead in Rio state, compared to 602 in all of 2017, said the city sanitation service, launching a campaign against the killings.
When people kill them, the virus is harder to trace.'A dozen small dead monkeys lay on a table at the lab in preparation for examination.Yellow fever is a viral disease transmitted by mosquitoes in tropical regions and is still a major killer in Africa.It had largely been brought under control in the Americas.The first sign that the fever was back in Brazil was the death last year of hundreds of monkeys in the Atlantic rain forest in the states of Rio de Janeiro, Espirito Santo and Sao Paulo.WHO said 777 human cases of yellow fever had been reported in eight Brazilian states since December 2016 and that 261 people had died from the virus.
