After being admitted to Riga Eastern Clinical University Hospital on Monday with an apparent viral infection, his office said he was continuing to work from his bed.
However on Tuesday an update said he had been transferred to Paul Stradins Clinical University hospital "for further investigations and treatment to prevent a further risk of infection."
In a development likely to cause some concern to the public, Presidential powers would be "temporarily transferred" from Wednesday to parliamentary speaker Inara Murniece, the President's office said, so that "all [his] energy can be devoted to recovery."
In Latvia, the Saeima speaker deputises for the President whenever he or she is unable to execute his official functions.
The public would be updated with "relevant information" about Vejonis' state of health as necessary, the statement said, before wishing him a speedy recovery.
