MONTEVIDEO – Health authorities in Uruguay are closely monitoring a patient in the northwestern city of Salto who may be suffering from what would the country’s first homegrown case of dengue fever, official sources told EFE.
Dengue, an illness of the tropics and sub-tropics, is not native to Uruguay.
The patient in Salto, a 39-year-old woman whose symptoms include fever and malaise, was presumably bitten by a mosquito that might have infected her with the virus, but an initial rapid-detection test produced negative results.
A report based on more thorough testing is expected to be available on Wednesday, the sources said.
Given that the patient has not traveled abroad, a positive result would mark Uruguay’s first indigenous case of dengue.
The ministry has issued an alert about risks for the spread of dengue, Chikungunya and Zika in the western regions of the country as a result of extensive flooding on the Uruguay River, which could provide an environment favorable to the proliferation of the Aedes aegypti mosquito that carries all three of those viruses.
