The Department of Health in Hong Kong announced on Wednesday that it will expand measles testing by providing tests for up to 200 Filipino domestic workers at the Immigration Tower in Wan Chai on Hong Kong Island.

A blood test station will be set up on the ground floor at the Immigration Tower on Gloucester Road in Wan Chai on Thursday and Friday to provide measles serology testing, according to a government release.

This is seen as an extension of a three-day pilot scheme that the health authority launched at Hong Kong International Airport in late April and early May.

The Department of Health said the scheme aims to better grasp the overall immunity against measles among Filipino foreign domestic workers in Hong Kong.

Meanwhile, two more staff from a Gucci outlet in Kowloon’s Tsim Sha Tsui were confirmed as infected with the measles virus on Tuesday, bringing the total number of measles sufferers among employees to five people. The shop earlier closed for business for two days and reopened on Wednesday evening, Apple Daily reported.
