Melbourne, Feb 11 (IANS) Two more people linked to Covid-19 outbreak at quarantine hotel in Australia's Melbourne city have tested positive for the virus, bringing the total number of the cluster to 10.

The Department of Health in Victoria state, of which Melbourne is the capital, said on Thursday that the two new cases were both household primary close contacts of the currently infected staff at the Holiday Inn at Melbourne Airport, reports Xinhua news agency.

The Holiday Inn cluster now stands at 10, including a family of three who is believed to contract the virus overseas, three quarantine hotel workers, two household members of the hotel workers and two former guests who exited the facility on February 7.

As investigations into the outbreak continued, the hotel was closed on Wednesday for terminal cleaning.

Forty-eight residents were transferred to Pullman Melbourne to quarantine for an extended number of days and more than 135 hotel staff were asked to isolated at home for 14 days.

A planned increase to Victoria's cap on international arrivals was also put on hold.

Other states and territories in the country were also on high alert as the Holiday Inn cluster in Melbourne expanded.
