Foodborne illness is being blamed for putting Thai Prime Minister Yingluck Shinawatra in a Bangkok hospital.

Ms. Yingluck, 45, was suffering from acute diarrhea and vomiting due to food poisoning, according to a government spokesman.   The Thai PM was admitted to the Rama IX Hospital where she was to remain at least overnight.

On Tuesday she asked the deputy prime minister to take over her government’s weekly cabinet meeting. The PM is scheduled to make a quick trip to Vietnam on Wednesday.   

Thailand has been hard hit by the worst flooding to occur in a half century and Ms. Yingluck has been frequently traveling the countryside working on recovery strategies.

The flooding has cut into Thailand’s economy, especially the Southeast Asian country’s  usually strong tourism industry.

Ms. Yingluck earlier this year became the first woman elected PM after her party won national elections.  Doctors expect she will be well enough to make the planned trip to neighboring Vietnam.

The exact pathogen that infected the PM was not disclosed.
