Household disinfection will only be conducted in the homes of COVID-19 positive cases. But if they live in old residential neighborhoods, the homes of their neighbors, who share common kitchens and bathrooms, will also be disinfected, according to Shanghai's housing authority.

Before conducting the home disinfection, community workers must fully communicate with the infected persons and their families, seeking their understanding and cooperation.

Residents should also tell the staff about any belongings that are sensitive to disinfectants or need special protection, Jin Chen, deputy director of the Shanghai Housing and Urban-Rural Development Commission, said.
