The condition of veteran Congress leader K Karunakaran, undergoing treatment at a private hospital here for fever and breathing problems, has improved considerably, attending doctors said on Saturday.
His condition was "much better" and he was responding well to medicines. He would have to be in the critical care unit for the next three days, they said.
The 91-year old former chief minister was admitted to the Ananthapuri Hospital on Thursday in a serious condition with high fever and breathing problems. Though in the initial hours he was unconscious, he began responding to treatment by afternoon, the doctors said.
Karunakaran had five stints as Kerala chief minister since 1977. He also served as the Union industries minister in the Narasimha Rao government.
