Brazilian president, Jair Bolsonaro, is being treated for pneumonia, having been a fever on Wednesday, the Albert Einstein hospital in Sao Paulo has said.
Bolsonaro recently had a follow-up operation to remove a colostomy bag that was introduced after being staked during the campaign prior to Brazil's elections last year.
Albert Einstein Hospital said in a statement on Thursday that it had conducted tests on President Jair Bolsonaro.
"He underwent a tomography on the chest and abdomen that showed a good development in the intestinal frame and images compatible with pneumonia," read the health insurance statement.
Doctors say Bolsonaro does not eat fast food, do exercises, and has no pain.
Presidential spokesman Otavio Rego Barros said the president was in semi-intensive care.
Bolsonaro checked in at the hospital on January 27 to remove a colostomy bag in place after he was stabbed d during a campaign rally. His recovery in the hospital was initially expected to take seven days.
