Coronavirus killing
The new type of coronavirus is coming fiercely, and ultraviolet light and medical alcohol can kill the new type of coronavirus. This article will explain in detail why ultraviolet light can kill the new type of coronavirus.
At the beginning of 2020, the hearts of hundreds of millions of people have been held by the new coronavirus pneumonia. When the epidemic broke out, people hoarded all kinds of medical and daily necessities out of self-protection or panic, and they also raised many questions. For example, can ultraviolet lamps kill the new coronavirus?
The author summarized it by inquiring a lot of information for your reference. Let me start with the conclusion: ultraviolet light can kill the 2019 new coronavirus, which is medically named 2019-nCoV. UV light intensity meter is used to test the light intensity of the uv lamp.
Let me briefly talk about the virus. All living things, including humans, are composed of cells, while viruses are cell-free, mainly composed of protein coats and nucleic acids (a genome composed of one or more nucleic acid molecules: DNA or RNA), so strictly speaking, It is not a living thing, and because of this, the virus can only survive, metabolize, and reproduce in the cells of a certain organism. Once it leaves the living body, it will die in a short time.
The specific length depends on the strength of the virus itself, the weak for a few minutes, the general tens of minutes, and the strong can even survive for more than 48 hours. Academician Li Lanjuan once said: The new coronavirus can only survive for 48 hours in a dry environment, but after 2 hours of exposure to the air, its activity is significantly weakened.
In addition, the new coronavirus is replicated through RNA, and the process of ultraviolet disinfection mainly acts on the nucleic acid (RNA) of the virus and destroys the protein layer of the virus, thereby affecting its survival and replication ability. This process is called "inactivation" in medicine.
