Abstract: In the fight against COVID-19 epidemic, some patients lack legal awareness, respond strongly to the quarantine requirements of the relevant departments, and even refuse to accept the combination of quarantine treatment. Such behavior poses danger to social security. If the perpetrator enters a public place, it is easy to spread the virus and endanger the public security. Therefore, recently, the six departments under the Central Government, the Supreme Law and the Supreme Prosecutors Office jointly formulated the “Opinions on the Legal Punishment of the Crimes of Preventing and Preventing the Epidemic of Pneumonia Infection by the New Coronavirus”, which defines the intentional transmission of the new coronavirus as a criminal offence. This paper analyzes the necessity and accurate application of the crime of endangering public safety by dangerous methods, and makes a comprehensive legal evaluation of the relevant behaviors in combination with the relevant legal texts, with a view to putting on a “legal mask” for the society and providing help for the “legal good medicine” to overcome the epidemic situation. 

Key words: Novel coronavirus, patient of COVID-19, crime of endangering public safety by dangerous means, the expectation of possibility, the admission criteria
