The Unawatuna sub-railway station has been closed down temporarily due to the fear of COVID19.
A senior official attached to the railway station has been identified as a close contact of the person in Habaraduwa who was tested positive.
The Habaraduwa patient contracted the disease from the Kandakadu cluster which has resulted in a surge of COVID19 patients in Sri Lanka.
Health authorities said 623 active COVID19 patients are currently receiving treatment in hospitals.
