KATHMANDU: The building which houses two health facilities in Pulchowk -- Nidan Hospital and Aarogya Foundation -- has been sealed off after a staffer was detected with COVID-19 infection.

An eyewitness who passed through the area stated that the building premises have been sealed off with ropes and security personnel have been mobilised.

The female staffer working at Aarogya Foundation was detected with coronavirus infection, on Tuesday.

Focal person of Infectious Diseases at District Health Office, Lalitpur, Indira Bhandari, said, the person had travelled to Sunsari on April 21 and returned to Bhaktapur on May 11 on a relative's motorbike.

She had called an ambulance from Nidan and visited Teku-based Sukraraj Tropical and Infectious Disease Hospital after suffering some problems in her health, focal person Bhandari added.

She then gave her sample for testing at Teku hospital and returned home. According to Bhandari, the staffer has not entered the hospital premises after returning from Sunsari. However, the driver of the ambulance and another staff member accompanying him had returned to Nidan afterwards.

The driver and the other staffer have been referred to Patan Hospital for testing, said Bhandari.
