Shanghai plans to build a 3,250-bed Covid-19 quarantine facility on a small island close to its city centre, as China stands by its zero-Covid controls.

The city awarded a 1.38 billion yuan contract to build the centre on Fuxing Island, located in the Huangpu River, to state-owned builder China Communications Construction, according to a government document.

The document said the site, which will take in positive cases and their close contacts, would be 140,000 square metres large and have 3,009 rooms. It did not give a timeline for the project's completion.

Shanghai, like other Chinese cities, has continued to battle sporadic outbreaks with repeated mass testing and targeted lockdowns.

Other localities have built similar quarantine sites. The southern city of Guangzhou has a 5,000-bed quarantine centre that is mainly meant for travellers entering the mainland from abroad. (Reuters)
