The Bangladeshi government says President Iajuddin Ahmed is recovering from a high fever at a Dhaka hospital.
The 77-year-old president was hospitalized with a viral fever late Monday at the Combined Military Hospital.
In 2006, Mr. Ahmed had heart surgery in Singapore.
The president has little authority over day-to-day affairs in Bangladesh's parliamentary democracy, with most powers held by the prime minister.
But in 2007, Mr. Ahmed declared a state of emergency after elections were canceled following months of political turmoil.
He appointed a military-backed interim government to conduct a widespread campaign against alleged government corruption.
Authorities have arrested some 170 politicians -- including two former prime ministers -- and business people as part of the massive anti-graft investigation.
