Netflix’s series “72 Dangerous Animals: Latin America” falsely claims that howler monkeys transmit yellow fever to humans. This myth has long led to the wholesale slaughter of monkeys by misinformed people. With this series, Netflix is destroying the efforts of awareness campaigns and threatening the conservation of primates.

“Netflix must stop streaming the 7th episode of the series “72 Dangerous Animals: Latin America” worldwide.”

Yellow fever is a deadly disease transmitted by mosquitoes.

It is commonly believed that howler monkeys are reservoirs of yellow fever and transmit it to humans, but this is WRONG. Howler monkeys mostly die of it in a matter of days, and when they don’t, they develop immunity. Thus, they are not reservoirs of the disease – on the contrary, they play an important role as sentinels: howler monkeys are a “canary in the coalmine”, with dead animals providing an early warning to local health authorities, alerting them to the presence of the disease. Furthermore, only mosquitoes are capable of transmitting the disease to humans.

These falsehoods regarding the role of the monkeys, conveyed by the media, spread quickly among the population during the 2007-2009 yellow fever outbreak in Brazil, and people afraid of contracting the disease went on a rampage, killing howler monkeys. 

Some howler monkey species are listed as threatened by the IUCN, and considering their role as yellow fever sentinels, it is crucial for human health that we protect them. The campaign “Protect our Guardian Angels”, launched in 2009, promotes vaccination and raises awareness of the howler monkeys’ value in protecting humans against the disease.

The 7th episode of the new Netflix series “72 Dangerous Animals: Latin America,” launched on the 22nd of December 2017, claims that howler monkeys transmit yellow fever to humans. This flies in the face of a massive campaign to raise awareness of the true nature of yellow fever. People often trust the media more than scientific studies, exposing monkeys to the threat of further wholesale killings. We call on Netflix stop streaming this sensationalist and flawed episode.

Letter

To: Netflix Chief Content Officer Mr. Ted Sarandos

Dear Mr. Sarandos,

Since the 22nd of December 2017, Netflix has been streaming a new series by Showrunner Productions entitled “72 Dangerous Animals: Latin America”. The 7th episode of the series claims that howler monkeys are dangerous because they can transmit yellow fever to humans.

This statement is wrong: it is well known among the scientific community that mosquitoes are vectors of the disease. The myth that howler monkeys transmit the disease to humans, largely conveyed by the media, spread quickly among the population during the 2007-2009 yellow fever outbreak of Brazil. It resulted in the pointless, widespread killing of howler monkeys by people afraid of contracting the disease.

Howler monkeys from the regions south of the Amazon are threatened with extinction according to the IUCN. Furthermore, they play an important role as yellow fever sentinels, since their death provides an early warning to health authorities of the presence of the disease and the need to vaccinate local populations. Campaigns such as “Protect our Guardian Angels” and “Celebrities against Yellow Fever,” launched in 2017 and supported by 29 educational, scientific and governmental institutions and NGOs, promote vaccination and raise awareness of the howler monkeys’ value in protecting humans against the disease.

However, people often trust major media outlets more than scientific studies. Due to its large audience, Netflix has a huge impact on people and has the responsibility to convey reliable, validated information when streaming documentaries. This episode flies in the face of the massive campaign to raise awareness of the true nature of yellow fever and protect monkeys against the threat of further wholesale killings. We call on Netflix to stop streaming this sensationalist and flawed episode worldwide and be more careful in their choice of documentaries in the future.

Yours faithfully,
