The head of the World Health Organization said on social media platform X on Thursday he had been discharged from a hospital in Rio de Janeiro after being admitted overnight.
"I felt unwell yesterday afternoon and was admitted to Samaritano Barra Hospital in Rio, but I was discharged this morning and am back to work," said Tedros Adhanom Ghebreyesus.
Tedros, 59, suffers from hypertension. He was in Rio de Janeiro for the G20 summit where he met with US President Joe Biden and other leaders, advocating for strengthened global cooperation in health emergencies.
Local newspaper O Globo had reported earlier on Thursday that Tedros sought medical attention at the facility with "symptoms of labyrinthitis and an hypertensive crisis," after showing signs of being unwell.
According to the report, Tedros was examined on Monday by health professionals on duty at the G20 summit and given medicine for high blood pressure, but was released once he was stable.
