Monkeys are a warning for yellow fever: killing them is not the solution

Monkeys are a warning for yellow fever: killing them is not the solution

which appear daily on yellow fever, added to the fear and insecurity of the population, it is almost inevitable that many rumors will gain prominence. One of them, who was circulating through social networks, is that some people were trying to kill the monkeys living in the areas with the highest incidence of the disease.

There are no official data on these acts, but we believe in My Life that information is the best way to clarify these myths and prevent them from continuing to spread.

Monkeys are not transmitters

Did you know that monkeys are the victims, as we are, of yellow fever? "Monkeys get sick from yellow fever as much as humans, they are more susceptible, but they are not vectors of the disease," explains the infectious disease Carolina Lázari of Fleury Medicina e Saúde. In other words, they do not transmit yellow fever. The process of contagion is much more complex than simple contact with the animal, something that does not cause the disease to contract. "There must be a mosquito, a susceptible population, a complete ecological system that generates the cycle of the virus." The monkey can not be held responsible, because in that sense the role of the monkey is like that of the human being. Understand how yellow fever is transmitted

Monkeys act as reservoirs of the yellow fever virus, which means they already have the virus in their body normally. In this context, the Haemagogus and Sabethe mosquitoes, common in wild areas, are contaminated by stinging monkeys. These mosquitoes become vectors of wild yellow fever, transmitting the disease to humans by pricking them.

There is also urban yellow fever, transmitted by the Aedes aegypti mosquito, which is more common in large cities and metropolitan areas. Both urban and wild yellow fever contains the same virus, which changes is the transmitting agent, in this case the mosquito species. Wild yellow fever is considered endemic, that is, recurrent in the northern region of Brazil and a higher incidence in rural areas. Urban yellow fever has not been recorded in Brazil since 1942. But if the monkey already has the virus and lives well, why are so many dying? "An already contaminated mosquito can prick a monkey and increase the viral load of this primate.This situation contributes to increase the number of deaths of monkeys due to yellow fever, causing that consequently the mosquitoes that sting these monkeys also have a higher viral load and also contaminate humans with more viruses, "explains epidemiologist Helena Brígido, arbovirus specialist at the Brazilian Society of Infectious Diseases.

Monkeys help map the disease

Besides the monkeys are not to blame for the yellow fever situation, they are still great allies of the public agents who accompany the disease cycle and alert public authorities to a possible spread of the disease. "The monkey, as it is more sensitive than the human, ends up dying of the disease and so we can anticipate the moment of circulation of the virus when we perceive the death of monkeys. They warn us that the amount of virus is high, they function as sentinels, "explains the infectologist Carolina.

" Throughout the year and in periods between outbreaks, surveillance takes over the monkeys, because if they appear dead susceptible species, they are collected for analysis. In addition, from time to time monkeys are captured to observe the circulation and load of the virus in wild areas, "Carolina adds.The Environmental System Paulista, responsible for environmental management in the state of São Paulo, stresses that assaulting or killing monkeys is an environmental crime (Federal Law 9605/1998, Article 29) and impairs the work of prevention of outbreaks of yellow fever.

If you find a sick or dead monkey, do not move and do not transport the animal because there is a risk of contamination by other diseases (not by the yellow fever virus); please contact the Municipal Epidemiological Surveillance immediately (see the website of the municipality of your municipality) or the Epidemiological Surveillance Group (EWG). If you find a live and healthy monkey, do not capture and transport the animal, do not feed it, mistreat it and do not kill it.

Better ways of prevention

Immunization of the population in risk areas is the best way to avoid disease. "You have to keep an eye on the vaccination campaigns, if you vaccinate without panic and respect the moments of convocation by the health agencies and follow the public guidelines. Be aware of the prohibited areas, the recommendations and also the contraindications of the vaccine," says Carolina . Some groups may not take the yellow fever vaccine and this recommendation is very important to be followed. "Get advice and if you know you can not be vaccinated, protect yourself in other ways, use repellents and stay away from dangerous areas," he says.

In this way, the release of adrenaline increases heart rate, which speeds up metabolism and energy consumption, resulting in weight loss. A 2012 study at the University of Westminster measured how many calories were burned by volunteers who watched ten horror classics. On average, each film burns 113 calories, equivalent to a 30-minute walk.

Processed food may increase risk of cancer

The lack of time ends up causing many people to stop eating healthy and to eat many processed foods. However, this habit may increase the risk of cancer. Scientists at the University of Swansea in the UK have found that people who consume processed foods in large quantities have an increased number of damaged red blood cells.
