RIO DE JANEIRO, Feb. 7 (Xinhua) -- Brazil's President Jair Bolsonaro had a fever and showed signs of pneumonia, his medical team reported on Thursday.

The Albert Einstein Hospital, where Bolsonaro is recovering from a surgery performed in late January, said that the president was given a chest tomography earlier in the day, which indicated pneumonia.

Government spokesperson Otavio Rego Barros said the president will be taking antibiotics for a week.

The hospital added that the president is recuperating in a satisfactory manner from January's surgery after he survived a stabbing attack during his campaign rally last September.

"President Bolsonaro continues to feel no pain, is using a nasogastric tube and abdominal drains, and is consuming liquids orally in association with parenteral nutrition," said a hospital bulletin released on Thursday.

Bolsonaro was stabbed in the abdomen during the campaign by a lone attacker. The perpetrator was immediately arrested. Bolsonaro was injured in the intestines and was given a colostomy.

The colostomy reversal was supposed to take place in December, but was postponed twice and took place on Jan. 28.

The surgery took seven hours and was deemed a complete success. However, Bolsonaro's recuperation has taken longer than expected. It was initially announced that he would be discharged from hospital on Feb. 6, but was then postponed to Monday. Now doctors have not confirmed a precise date to discharge him.
