The first epidemic of 2019 novel coronavirus (2019-nCoV)-infected pneumonia(NCIP) in Wuhan, China, has attracted global attention because of its strong transmission ability and certain fatality. Analyzing the clinical data of hospitalized patients with 2019-nCoV infection, the current studies found that fever, fatigue and dry cough were common symptoms, and 43.8% of the patients showed fever before admission. Some scholars emphasize that the most effective means to control the outbreak are early detection, early isolation, early diagnosis and early treatment. In the face of the pressure that a large number of people need rapid screening and the deficiency that the forehead temperature measurement is easily affected by the environment, the investigators would like to explore the accuracy and advantages of wrist temperature measurement in different environments and conditions in this period. And determine the thresholds of non-contact infrared thermometer for the screening of patients with fever, in order to provide clinical indicators for further detection of patients with suspected fever.
