Argentine President Cristina Fernandez de Kirchner is back in hospital, the latest in a series of health issues she’s dealt with in the past year.  A government spokesman says CFK is in stable condition and is being treated for a bacterial infection of the colon.

The illness forced President Fernandez to cancel an official visit by Chile’s President Michelle Bachelet planned in Buenos Aires on Tuesday. 

It’s been a rough year for CFK.  In mid-October, doctors told the 61-year-old president to rest for 48 hours in order to recover from a sore throat.  In July, she missed Independence Day celebrations to continue recovering from an acute throat infection.  And in January, Fernandez was treated for hip pain and sciatica.

Last year, she underwent head surgery to remove a blood clot, and made no public appearances during a 40-day period between December and January, causing concern over her condition and much speculation in the media.
