According to Vadivelan, the medical team will look out for persons with high fever and in confused state of mind, the symptoms of Nipah virus fever.
He said there will be an isolated ward in a government hospital in the seven districts to admit and treat the patients tested positive for the virus.
The seven Tamil Nadu districts are Kanniyakumari, Theni, Tirunelveli, Ooty, Coimbatore, Tirupur and Dindigul.
Vadivelan said the doctors in the border districts have been given detailed guidelines on the symptoms of the disease and how to handle the patients.
