In our last article "How to prevent monkeypox in medical institutions (Part.1)", we introduced the items medical institutions should care about in preventing monkeypox. Today, we are going to introduce the remains items need to know.
5. Laboratory safety protection
· Monkeypox virus culture, animal infection experiments, including the operation of uncultured infected materials need to be carried out in a BSL-3 laboratory.
· Monkeypox virus inactivation materials can be performed in a biosafety Level II laboratory.
· Relevant experimental operations shall be carried out in biosafety laboratories of different levels, with facilities and equipment of corresponding levels under the condition of personal protection.
6, Disinfection
Refer to the CDC for smallpox, vaccinia virus and other cleaning and disinfection methods
· Air disinfection: ventilation and ultraviolet disinfection are effective. There is no evidence to justify the use of fumigation and other disinfection methods in confined Spaces
· Medical devices: Disposable medical devices should be discarded as required; All reusable medical devices shall be cleaned as required after use, sterilized or subjected to high-level disinfection according to their intended use; No pre-soaking is necessary unless the device cannot be cleaned and reprocessed immediately after use.
· Fabric: Special isolation washing machine should be used for cleaning, not mixed with ordinary fabric. Processing from Fabrics of patients and their close contacts (such as sheets and clothes) should be stirred as little as possible to prevent scabs or skin fragments from being scattered into the air to avoid contaminating the air, surfaces and staff. Washing and disinfection of infectious medical fabrics should be carried out in accordance with the principles.
· Environmental surfaces: 500mg/L chlorine-containing disinfectant can be used to wipe/drag and disinfect indoor surfaces, walls and floors, etc. It is recommended to use disposable disinfectant wipes to clean and disinfect the environmental surfaces frequently touched by hands at medium and low levels.
7. Medical waste treatment
· Household waste generated by suspected or confirmed monkeypox patients should be treated as medical waste.
· Medical waste should be wrapped in time when 3/4 of the time is full, and squeezing is strictly prohibited. The bag mouth should be sealed by gooseneck tie. Before leaving the contaminated area, the surface of the bag should be sprayed with 1000mg/L chlorine-containing disinfectant for disinfection (spraying evenly) or the outer layer of medical waste packaging bag should be placed, labeled, and sealed in time for transport.
As long as we pay attentions to the items we mentioned about, the monkeypox virus can be prevented effectively.
