Chavez underwent his fourth cancer operation on 11 December in Cuba but suffered a respiratory infection. The president - in power since 1999 - won another term in October\'s election. Earlier, Venezuelan Information Minister Ernesto Villegas said: \"The patient has shown a slight improvement in his condition.\" However, no pictures of Chavez after the surgery have been released so far. Chavez, 58, is scheduled to be sworn in on 10 January.
