Bolivia's interim president Jeanine Anez announced Thursday that she has tested positive for the novel coronavirus.
"I've tested positive for COVID-19, I'm fine, I will work from isolation," she tweeted.
The 53-year-old said in a video on Twitter that she would remain in quarantine for 14 days before taking another test.
Anez becomes the second South American president in a matter of days to contract the coronavirus, after Brazil's Jair Bolsonaro announced his positive result on Tuesday.
Another high-ranking Latin American government official to contract the virus is Venezuela's Constitutional Assembly President Diosdado Cabello, widely considered the second-most powerful person in the country after President Nicolas Maduro.
Four members of Anez's cabinet had tested positive in recent days, while Senate President Eva Copa went into self-isolation on Wednesday as a precaution.
"Given many of them tested positive over the last week, I took the test and I was also positive," said Anez.
The interim leader's illness comes with Bolivia gearing up for a general election in less than two months, despite being in the middle of the coronavirus pandemic.
Anez initially opposed the September election, saying it should be postponed "one or two months" due to the pandemic, but eventually relented.
Rival candidate and former President Jorge Tuto Quiroga, who is running again, said it was "indispensable" for Anez to be in full health and working towards the democratic transition.
Bolivia, a landlocked Andean nation of over 11.5 million people has registered more than 42,000 confirmed cases of the disease and 1,500 deaths and is one of the worst affected countries per capita in the world.
