RIO DE JANEIRO, Oct. 25 (Xinhua) -- Brazilian authorities on Wednesday closed the biggest park in Sao Paulo, due to a suspected outbreak of yellow fever.
Local officials announced the closing of Anhanguera park, and recommended residents stay away from two other parks, Canivete and Corrego do Bispo.
The decision follows other closures, including the Huerto Florestal (Forest Orchard) in north of the city, where a howler monkey was recently found dead. Preliminary lab tests showed the animal died of yellow fever.
In a statement, the city Health Secretariat said the new closings were precautionary measures pending further tests.
Experts believe the Haemagogus mosquito, mostly found in tropical Central and South America, infected the monkey in the wild.
The monkey was found just a few weeks after Brazil's Health Ministry announced the end of a yellow fever outbreak in Sao Paulo, which left 261 dead and 777 people infected.
The city also announced a mass vaccination campaign focusing on people living around the Huerto Forestal.
