The new batch, announced yesterday, are linked to the same points of origin identified by authorities: Cheung Chau island and Lion Rock Park.

Two of them are residents of Cheung Chau and another had visited the island.

The fourth patient had been near Lion Rock Park in Wong Tai Sin.

The outbreak started earlier this month and authorities have been undertaking an intensive effort to eradicate mosquitoes.
