The corona virus disease 2019 (COVID-19), which started in Wuhan in December 2019, is a new infectious disease. The disease is highly contagious, and the correct selection of effective disinfectants is essential. This article analyzed the environmental resistance of coronavirus and its sensitivity to commonly used disinfectants by reviewing domestic and foreign literatures, and concluded that coronavirus has strong survivability in the environment, but it can be efficiently inactivated by most disinfectants. However, it should be noted that the commonly used concentration of chlorine-containing disinfectants (effective chlorine concentration of 500 mg/L) cannot quickly kill coronavirus, and a concentration of 1 000 mg/L or higher is required. Other biocidal agents, such as benzalkonium chloride and chlorhexidine digluconate, are less effective. This article aimed to provide references for selecting the appropriate disinfectants and disinfection methods to cut off the spread of the virus.

Chongqing Medicine.2020;49(0):E014-E014. doi:10.3760/cma.j.issn.9999-998X.2020.0014

The new coronavirus pneumonia has been listed as one of the Class B infectious disease but is managed as Class A infectious disease. To prevent and control its spread in hospitals, the outpatient department is the first key gate. Based on the relevant diagnosis and treatment strategies of the National Health Commission of the People's Republic of China, combined with the actual situation of the hospital's epidemic prevention and control work, this article formulated comprehensive prevention and control strategies from the perspective of the patients and staffs. From the aspects of organization and leadership, medical epidemic prevention, pre-screening and screening, process formulation, admission management, cleaning and disinfection, epidemic report, prevention and control supervision, personnel and material deployment, patient education, comprehensive management, personnel management and psychological support and so on, advice and guidance on prevention and control of this infectious disease in outpatient department of hospital were provided.

Objective To compare and analyse the detection performance of different 2019-new coronavirus (2019-nCoV) nucleic acid detection kits, in order to provide references for laboratory. Methods Six kinds of domestic reagents (A—F reagent) were selected for parallel detection of a series of samples from one patient in this hospital whose 2019-nCoV nucleic acid result was confirmed weakly positive. The samples were taken at three different times, the RNAs were extracted and amplified, and two parallel tests were performed each time by use of these six kits. The detection performance was compared according to the results of each kit. Results The three parallel test results (ORF1ab and N gene) of C and F reagents were positive, the results of D reagent showed the N gene was not detected, and the results of A, B, E reagents showed the ORF1ab gene was not detected sometimes. The reproducibility of in-batch detections by C reagent was the best, and the CT values of F reagents (N and ORF1ab), E reagents (ORF1ab) and A reagents (ORF1ab) showed changes in trend. Conclusion There are differences in the detection ability of six 2019-nCoV nucleic acid detection reagents for weakly positive samples, and the accuracy, sensitivity and reproducibility of some reagents are not good. There is an urgent need to further optimize and improve their performance in order to better meet the needs of large-scale screening.

Objective To investigate the psychological status of clinical nurses in a class A hospital facing the novel coronavirus pneumonia (NCP), in order to provide effective psychological and social intervention. Methods A total of 867 clinical nurses were randomly selected from the Mianyang Central Hospital. The general information questionnaire, standard self-assessment anxiety scale (SAS) and crisis intervention classification assessment scale (TAF) were used to conduct self-assessment questionnaire survey. Then the data were analyzed by the SPSS22.0 software. Results 38.8% of the nurses had a low risk of infection, 18.0% of them had a medium risk, 29.6% had a medium high risk, and 13.6% had a high risk. The SAS scores of clinical nurses in this hospital were statistically significant different, compared with the Chinese norm value ( P <0.05). The difference between TAF score and the degree of crisis response of nursing students in SARS period was statistically significant ( P <0.05). The majority of clinical nurses had less crisis response to NCP, with 80.7% of them suffered mild cognitive, emotional and behavioral damage, and only 2.0% suffered severe damage. Analysis of related factors showed that department, self-test risk of infection, length of service had significant influence on SAS and TAF scores of clinical nurses ( P <0.05). Conclusion During the period of NCP prevalence, no obvious anxiety and crisis reaction among clinical nurses is found in the third grade hospital. However, the psychological changes of clinical nurses with middle-age, from key epidemic prevention departments and in high risk of self-test infection are more likely to produce anxiety and crisis reaction. Therefore, appropriate and timely psychological intervention should be given.

Objective To investigate the core emergency response capabilities of medical workers for corona virus disease 2019 (COVID-19) public health emergency, in order to provide references for improving emergency level. Methods By means of convenient sampling, the general information questionnaire and the medical staff's 2019-new coronavirus (2019-nCoV) core emergency capability questionnaire were used to conduct this survey, and the status of 2019-nCoV core emergency capability of 629 clinical medical staff was analysed. Results The score of core emergency response capability of medical staff for 2019-nCoV was (135.60±21.73)points, with a score rate of 73.3%; the score of preventive capability dimension was (11.69±1.96)points, with a score rate of 77.93%; the score of preparation ability dimension was (20.79±4.18)points, and the score rate was 69.30%; the score of rescue ability was (103.11±16.93)points, with a scoring rate of 73.57%. Conclusion The core emergency response capability of medical worker for 2019-nCoV and its dimensions are at a medium level. At the present stage, the training of core knowledge of medical personnel 2019-nCoV should be strengthened, effective measures should be taken to improve the alleviation of weakness in rescue, and the self-psychological adjustment of medical personnel should be strengthened to improve the core emergency response capability of medical worker.

Since the end of 2019, an outbreak of pneumonia caused by a novel coronavirus named 2019 novel coronavirus (2019-nCoV) has occurred in in China. The dramatically rapid spread and strong infectivity of this virus has attracted global attention. Neonates are thought to be susceptible to the virus, because their immune system is not well developed. Neonates have been reported to be affected by this virus. The Chinese Medical Association, Chinese Medical Doctor Association, Pediatric Professional Committee of the Chinese People's Liberation Army have put forward strategies for the effective prevention and control of the 2019-nCoV infection in neonates. This expert review summarized the key points of the above three prevention and control consensus and programs.

Chongqing Medicine.2020;49(0):E022-E022. doi:10.3760/cma.j.issn.9999-998X.2020.0022

Since the outbreak of Coronavirus disease (COVID-19) in Wuhan, Hubei province, it has spread all across the country. Due to its highly contagious capability with relatively long incubation period and high incidence of susceptibility in the population, it has led to a large number of infected cases. Especially our medical practitioners who are working at the frontline of disease prevention and control. They stay in direct contact with the patients that it can easily lead to the spread of COVID-19 epidemic among doctors and patients and among patients themselves, which will give rise to nosocomial infection outbreaks and paralyze the medical work in departments and hospitals as well. Therefore, strengthening the management of nosocomial infection during the epidemic and improving the prevention and control of the Coronavirus disease has become top priority for departments of hospital infection control in medical institutions. In this article, we mainly introduce current information for COVID-19, prevention training, process designing in hospital, the use of PPE, disinfection and sterilization etc. We hope this will help to further clarify the duties and tasks for departments of infection control.
