Association between 2019-nCoV transmission and N95 respirator use

2019-nCoV had caused pneumonia outbreak in Wuhan. Existing evidence have confirmed the human-to-human transmission of 2019-nCoV. We retrospectively collected infection data from 2 January to 22 January at six departments from Zhongnan Hospital of Wuhan University. In our study, we found N95 respirators, disinfection and hand washing can help to reduce the risk of 2019-nCoV infection in medical staffs. Our results call for re-emphasizing strict occupational protection code in battling this novel contagious disease. The risk of 2019-nCoV infection was higher in the open area than in the quarantined area. N95 may be more effective for 2019-nCoV infections.

Clinical Characteristics of 138 Hospitalized Patients With 2019 Novel Coronavirus-Infected Pneumonia in Wuhan, China

In this single-center case series of 138 hospitalized patientswith confirmed NCIP in Wuhan, China, presumed hospital-related transmission of 2019-nCoVwas suspected in 41% of patients, 26% of patients received ICU care, and mortality was 4.3%.

Potential Maternal and Infant Outcomes from Coronavirus 2019-nCoV (SARS-CoV-2) Infecting Pregnant Women Lessons from SARS, MERS, and Other Human Coronavirus Infections

It remains to be seen during the current Wuhan 2019-nCoV epidemic how this newly-emergent coronavirus affects pregnant women and their infants, as well as which factors may modulate obstetrical disease and outcomes including the timing of maternal coronavirus exposure by gestational age, the effects of edications or other treatment regimens, differences in host immune responses, occurrence of coexisting medical and obstetrical conditions, and other covariables. However, pregnant women should be considered to be at high risk for developing severe infection during this current outbreak of 2019-nCoV. infection moved rapidly through China, spread to Thailand and Japan,extended into adjacent countries through infected persons travelling by air, eventually reaching multiple countries and continents.

新型冠状病毒感染重型及危重型呼吸治疗相关操作防护措施专家共识

自首例新型冠状病毒肺炎确诊以来，已有大量人传人的病例，其中超过 1700 例医护人员遭受了感染。对危重症患者进行呼吸治疗时有大量高危操作，例如气管插管、简易呼吸器辅助通气、无创正压通气、高流量鼻导管治疗、气管镜检查、吸痰以及转运等均可引起或加重患者气道内呼出病毒的大量传播。因此，我们根据目前最佳证据以及国内现有条件制定了本防范建议，旨在降低医护人员感染风险的同时为患者提供最佳治疗。

加强新型冠状病毒眼部感染的基础和临床研究

我国新型冠状病毒疫情防治工作进入关键期，眼表是冠状病毒潜在的感染途径之一。本文结合国内外的研究进展和相关研究结果，总结新型冠状病毒在眼部可能的感染途径和临床特征，并对下一步的防治和研究工作进行建议，希望对我国感染性眼病领域的发展有所帮助。（中华眼科杂志，2020，56：）

Evaluation of coronavirus in tears and conjunctival secretions of patients with SARS-CoV-2 in fection

A prospective interventional case series study was performed, and 30 confirmed novel coronavirus pneumonia (NCP) patients were selected at the First Affiliated Hospital of Zhejiang University from January 26, 2020 to February 9, 2020. At an interval of 2–3 days, tear and conjunctival secretions were collected twice with disposable sampling swabs for reverse transcription polymerase chain reaction (RT-PCR) assay.
