‌‌Courtyard cleaning

      Firstly, the accumulated water in the courtyard should be thoroughly cleaned up, and the flooded areas should be cleaned up to promptly remove any remaining garbage and waste, in order to reduce environmental pollution and the risk of infectious disease transmission. For items that are not easily absorbent, such as metal, glass, and hard plastic, they can be restored to use after cleaning and drying. For items with strong water absorption, such as carpets, it is recommended to consider discarding them as they are difficult to thoroughly clean and dry.

Cleaning and disinfection of items

      Follow the principle of 'clean first, disinfect later'. For items that are not easily absorbent, chlorine containing disinfectant can be used for spraying, wiping, and disinfection. After 30 minutes of use, rinse with clean water. Catering utensils should be disinfected by boiling first, and the boiling time should be at least 15 minutes. For the surface of the faucet and the inner wall of the faucet that may be contaminated, effective chlorine can be used to wipe and disinfect it. After 30 minutes of use, clean it with clean water and open the faucet to rinse the pipeline and outlet.

Cleaning of the surrounding environment of the courtyard

      Timely clean up rainwater and garbage around the courtyard, turn over pots and cans to remove accumulated water, in order to reduce mosquito breeding. Use insecticides when necessary. Flooded water sources, toilets, livestock breeding sites, etc. should be thoroughly disinfected.
