Neighbours of the Ko family attempted to keep a low profile yesterday. Many said they knew nothing about the family, while others refused interviews.

The public housing block at Cheung On Estate, Tsing Yi, where the family lives, was washed and disinfected on Wednesday night and again yesterday morning.

No one answered the door at their flat yesterday and a female relative refused to comment when she entered the apartment. One neighbour said his family had kept all their windows open and disinfected their floors with bleach. 'But there's not much to be afraid of really,' said Mr Lam, who lives opposite the Ko family.

Another neighbour, who declined to give her name, said she was concerned about the situation but did not know what action to take.

The chairman of the mutual aid committee of the On Yeung Building, where the Kos live, criticised the Health Department for a lack of information. 'They were late [in informing us],' said Lau Pik-kin. 'People round here are naturally worried but in the absence of information it's difficult to address their worries.'
