sources of data
We obtained the number of NCP patients’ data released by the Zhejiang health commission from January 20 to February 8 (Zhejiang province found the first confirmed NCP patients on January 20). And we collected the government response measures to the disease of NCP from the Zhejiang government’s announcement.
diagnostic criteria for NCP patients
A confirmed NCP patient was diagnosed with respiratory or blood specimens that tested positive for NCP by at least one of the following two methods: 1.at least two positive results by real-time reverse-transcription-polymerase chain-reaction (RT-PCR) assay for NCP; 2. a genetic sequence that matches NCP(8). The above standard confirmed all the NCP patients in Zhejiang province. And Zhejiang health commission released the daily new diagnosis of NCP patients.
the collection information and criteria
We collected the government response measures to the disease of NCP through the Zhejiang government’s announcement from January 20 to February 8. And we would arrange the detail of actions in the part of the results. The value of steps was analyzed in the part of the discussion.
We recorded the details of NCP patients in Zhejiang province that were released by the Zhejiang health commission from January 20 to February 8.
We recorded the number of accumulative confirmed NCP patients, the daily number of newly diagnosed NCP patients, the accumulated amount of discharge NCP patients, the daily number of discharge NCP patients. The patients staying in ICU were paid more attention.
We recorded the epidemiological history of all the confirmed NCP patients. We divided the patients’ epidemiological history into four types: 1. from Hubei province: the patients travel from the Hubei province in the past 14 days; 2. from other area: the patients travel from other cities in China (it also contained that the patient might travel from other cities in Zhejiang province) or other countries in the past 14 days; 3. local infection: the patients did not have the travel history but had the contact history of the confirmed or suspected NCP patients in the local area in the past 14 days; 4. unknown: the patients did neither have the travel history nor the contact history of the confirmed or suspected NCP patients in the local area in the past 14 days. The imported NCP patients contained the types of from Hubei province and other regions.
We recorded the clinical symptoms of all the confirmed NCP patients. According to the announcement of Zhejiang health commission, we recorded the following clinical symptoms: fever, respiratory symptoms (it contained cough, expectoration, and pharyngalgia), digestive tract symptoms (it contained stomachache, diarrhea, nausea, and emesis), muscle and neurological symptoms (it contained headache, muscular soreness, and lacked in strength), abnormal changes in chest CT, or without clinical symptoms. The number of the above symptoms was counted. And we would show the data in the part of the results.
We recorded the time from clinical signs to NCP diagnosis for every confirmed NCP patient from the announcement of the Zhejiang health commission. For example, zero-day might mean that this patient’s time from clinical symptoms to NCP diagnosis was less than 24 hours. And two days might suggest that this patient’s time from clinical signs to NCP diagnosis was less than 72 hours but more massive than 48 hours.
We paid attention to the condition of whether the health care worker had got the infection of NCP and recorded the number of health care workers with NCP.
statistical analysis
For the characteristics of NCP patients, we used SPSS 25.0 to analyze the data average and mean deviation.
