High cleanliness and hygiene standards are some of the first lines of defence against public health threats. From 30 Jul 2021, the new environmental sanitation regime, which introduces mandatory baseline environmental sanitation standards, will be rolled out progressively at higher-risk premises with immuno-vulnerable occupants and at premises with high footfall. More than 3,000 of these specified premises, such as eldercare facilities and schools, are expected to implement the regime by 1 Mar 2022.
