アドバイス

The virus that causes Oropouche Fever is common in Central and South America and may cause large and explosive disease outbreaks. The virus is transmitted through mosquito, tick and midge bites. When these insects become infected with the virus, the virus can be transmitted to animals (sloths, marsupials, primates, birds) and humans through the insect bite. Transmission to humans is primarily by the bite of the midge. The bite of the midge carrying Oropouche virus feels like a sharp prick and an irritation or lump may appear and last for a few hours or days.

Avoiding contact with infected midges, especially during the rainy season, is the primary preventative measure. Avoid insect breeding sites (swamps, stagnant water, marshes, decomposing vegetation etc.). If possible, use insect repellent containing 20 percent or more of DEET and wear protective clothing to cover exposed skin.
