Despite the number of people under observation coming down drastically, state Health Minister on February 28 said there should be no complacency as reports of the coronavirus raging in many countries are coming in.

"As many as 3,500 people in Kerala were under observation and on February 28. It has come down to just 136 (128 in homes and eight in hospitals). We will be on a high alert and the airports and other ports of entry to our state will continue to be monitored closely. So let us continue our alert and all those who come from places where the virus has been reported, will be looked into," said the Health Minister. She said one person who returned from Malaysia and showed symptoms, has now been cleared, after the test results were negative.
