Singapore is to tighten Covid-19 testing requirements for shore-based staff after two people were found to have contracted the virus after flouting government advice designed to combat its spread.

Personnel will now have to be tested every seven days, instead of 14, before they are allowed to board ships for work, the Maritime and Port Authority (MPA) said.

Singapore’s Ministry of Health (MOH) had earlier reported that a marine surveyor and a harbour pilot had tested positive for Covid-19 on 30 and 31 December, respectively.
