To: People’s Committees of provinces and central-affiliated cities.

COVID-19 is progressing unpredictably around the world and in Vietnam. As of 23/3/2020, COVID-19 is detected in 19 provinces and cities across the country.

To ensure environmental hygiene and stop the spread of the disease, the Ministry of Health has formulated a set of interim guidelines for environmental decontamination and disinfection of areas accommodating COVID-19 patients in the community (enclosed therewith).

The Ministry of Health hereby requests People’s Committees of provinces and central-affiliated cities to direct Departments of Health and relevant units to perform environmental decontamination and disinfection in accordance with the guidelines and to inspect and supervise such performance.

With sincere thanks./.

5. Procedures

5.1. Inside houses/rooms/apartments of COVID-19 cases and inside adjacent rooms/apartments

a) Cleaning and disinfection

Apply the 2-bucket wash method with one bucket filled with clean water and the other filled with a disinfectant solution containing 0,05 – 0,1% active chlorine. Use a clean towel for each wiping turn, do not rinse towels in the buckets and use each towel for an area no larger than 20 m2.

- Wipe frequently touched surfaces (tables, chairs, bed frames, dressers, refrigerators, doorknobs, toilets, wash-basins, faucets, kitchen cabinets, walls, windows, doors, etc.) as follows:

+ Replace the water or disinfectant solution when it is dirty.

b) Waste collection

- All waste from accommodations of COVID-19 patients must be treated as biomedical waste. Put the waste in yellow bags, tie each bag tightly, put it inside another yellow bag and tie this bag tightly as well. All yellow bags must be labeled “CHẤT THẢI CÓ NGUY CƠ CHỨA SARS-CoV-2” (“Danger of SARS-CoV-2 infection”).

c) Handle reusable personal items (clothing, blankets, mosquito nets, tableware, etc.) of COVID-19 cases

- Used textile items such as clothing, blankets, mosquito nets, bed linen and pillows of COVID-19 patients must be fully soaked in a disinfectant solution containing 0,05% active chlorine for at least 20 minutes before washing.

- Tableware of COVID-19 cases must be fully soaked in a disinfectant solution containing 0,05% active chlorine for 10 - 20 minutes before rinsing with clean water (if disinfectants are not available, tableware may be boiled for 10 - 15 minutes).

5.2. Outside houses/rooms/apartments of COVID-19 cases and outside adjacent rooms/apartments/houses
