ABSTRACT
Objective: To describe the current reporting of pneumonia of unknown etiology (PUE) and factors that affect reporting by clinicians in China using the PUE surveillance system in order to provide a reference for improving PUE reporting rates in the future. Methods: Clinicians were recruited via the Sojump platform and requested to complete an anonymous self-administered questionnaire. Multivariate logistic regression analysis was used to assess factors influencing clinicians' reporting activities. Results: This study showed a low PUE case reporting rate and a poor understanding of PUE reporting among the investigated clinicians. Of the 136 clinicians who had diagnosed PUE cases, multivariate logistic regression analysis results showed that clinicians who had attended in-hospital training were more likely to report PUE than those who had not (OR 4.48, 95% CI 1.49-13.46). Clinicians with an expert panel on PUE in their hospital were more likely to report PUE cases than those without (OR 5.46, 95% CI 1.85-16.11). Conclusions: There is a need to promote and reinforce PUE surveillance system training among medical staff. In addition, PUE testing technologies in hospital laboratories should be upgraded, especially in primary and unclassified hospitals, to increase surveillance efficiency and improve PUE reporting rates.

ABSTRACT
Objective To study the homology and clinical distribution of tigecycline-resistant Acinetobacter baumannii (A.baumannii )in a hospital.Methods Multidrug-resistant A.baumannii (MDRAB,n = 88 )from specimens from clinical departments of a hospital in 2013-2014 were collected and detected susceptibility to tigecy-cline;homology of tigecycline-resistant strains were detected by pulsed-field gel electrophoresis (PFGE),clinical characteristics and distribution of infected patients were analyzed.Results 88 patients didn’t use tigecycline before MDRAB were isolated.Of 88 MDRAB strains,4 (4.55%)were resistant to tigecycline,which were No.10,31 , 33,and 87 strains.PFGE results revealed that No.31 ,33,and 87 strains were of the same genotype,and with high homology,which distributed in three different departments;No.31 strain was detected from general intensive care unit (ICU),No.33 strain was detected from emergency ICU,although strains were detected from different depart-ments,patients were transferred before strains were isolated,and were admitted to departments of gastrointestinal surgery and emergency ICU during the same period;No.87 strain was detected from neurosurgical ICU and patient had never been transferred,the detection time was 7-8 months later than No.31 and 33 strains.No.10 strain was isolated from emergency ICU,patient was not transferred.Conclusion Of MDRAB isolated in this hospital,tigecy-cline-resistant strains are low,most strains are homologous,cross infection may be exists in different departments.
ABSTRACT
Objective To evaluate the efficacy of disinfection and isolation measures in a hospital that received and treated the first case of imported Middle East respiratory syndrome(MERS)in China.Methods The first MERS case in China was admitted in the negative pressure room of the intensive care unit in a hospital on May 28,2015,a series of disinfection and isolation measures were taken for controlling and preventing MERS coronavirus (MERS-CoV)infection.Results One case of MERS confirmed by Guangdong Provincial Center for Disease Control and Pre-vention (CDC)and Chinese CDC were admitted in a hospital at 2:30 of May 28,2015,throat swabs and blood specimens of patients were detected as positive for MERS-CoV by real-time polymerase chain reaction.On the 3rd day,8th day,2 week after admission,and on June 21 ,throat swabs,blood,stool,and sputum specimen culture were negative respectively;before patient’s discharge,throat swabs,sputum,blood,and stool specimen culture were all negative for consecutive two times,there was no fever for 10 consecutive days,clinical symptoms were im-proved,patient finally recovered and was discharged on June 26.Detection of MERS-CoV were all negative for nasal swabs,throat swabs,and blood specimens from all health care workers (HCWs)participated in the treatment for MERS;all HCWs were performed physical examination from June 26 to July 10,none of them felt discomfort, there was no infection occurred among them.On the 7th,13th day of admission,and following terminal disinfec-tion,specimens of environment and object surface were taken and performed detection of MERS-CoV,all were negative.Conclusion Strict implementation of disinfection and isolation measures can effectively cut off the routes of MERS-CoV transmission and protect the safety of HCWs.
