The police have been directed to check fruits entering the state from Kerala.
The district health officer Dr Sudarshan asked the eight medical colleges in Mangaluru to keep patients under observation who come to them with suspected cases of brain fever.
Sudarshan told reporters here on Wednesday that directives have been issued taluk hospitals, primary health centres in the district to promptly conduct fever surveys.
Isolation wards have been made ready at key healthcare facilities including the district Wenlock hospital here. Private hospitals have also been asked to report any suspected case of Nipah or brain fever.
