'Sloth Fever' Virus Is Spreading. Here’s What You Need to Know about Oropouche
(www.scientificamerican.com)https://www.scientificamerican.com/article/sloth-fever-virus-is-spreading-heres-what-you-need-to-know-about-oropouche/Once confined to the Amazon region, the mysterious insect-borne virus that causes Oropouche fever has been expanding its range since late 2023, raising international concern. There have been more than 8,000 confirmed human infections in the Americas so far this year, most of them in Brazil, but Peru, Bolivia, Colombia and Cuba have also been affected.
Earlier this month, the Pan American Health Organization upgraded its risk level for Oropouche from moderate to high, citing the virus’s geographical spread and the occurrence of fatal cases, which are notable for a disease that has historically been known to cause mild to moderate symptoms. On 23 August, the World Health Organization published a note stating that the public-health risk posed by the virus is high at the regional level and low at the global level. The US Centers for Disease Control and Prevention has advised close surveillance of people returning from affected areas. Cases of Oropouche infection have been identified in people who have travelled to the United States, Spain, Italy and Germany from Brazil and Cuba, including 20 travelers from Cuba to the U.S. that the CDC reported on 27 August.
What is Oropouche?
Oropouche is a virus of the genus Orthobunyavirus. It differs from other better-known vector-borne viruses like dengue, Zika, yellow fever or Chikungunya because it is typically transmitted to humans by a midge, Culicoides paraensis, rather than by mosquitoes. But we cannot rule out the possibility that other vectors might be involved. [The virus has been found in other insects, including the mosquito Culex quinquefasciatus.]
For how long has this virus been around?
It was discovered in 1955 in Trinidad and Tobago, in the Caribbean. In 1960, it was first detected in Brazil from a blood sample taken from a sloth. Since the 1960s, it has been identified in outbreaks in humans more or less intermittently in the Amazon region [a vast area that spans nine countries in South America]. That’s why we say it’s a re-emerging virus, because it has been circulating for many decades at least in the Amazon, which is considered an endemic region.
yeah i dont think that releasing a bunch of dna altered mosquitoes by billy gates will help with the situation.
