Screening and management of asymptomatic infection of corona virus disease 2019 (COVID-19) / 中华预防医学杂志

To date, the controlling of outbreak of corona virus disease 2019 (COVID-19) has entered into a critical period in China. Recently, work resumption and public place is planning to open outside of Hubei, suggesting an uncertain and complex development of the epidemic in the next stage. Few days ago, we conducted a study on the epidemiological and clinical characteristics of asymptomatic infections of COVID-19, and found them might be the infection source. We believe that the findings are critical for developing public health intervention strategies for controlling COVID-19 infection in the future. Screening among the high-risk population and improving the sensitivity of measurement may contribute to the detection and management of asymptomatic infection.

Analysis of posttraumatic stress disorder in rescuers and firefighters / 中华劳动卫生职业病杂志

<p><b>OBJECTIVE</b>To investigate the occurrence and associated factors for posttraumatic stress disorder (PTSD) in rescuers and firefighters.</p><p><b>METHODS</b>The PTSD of 264 rescuers and firefighters who had participated in rescue was evaluated using the self-designed fireman general situation questionnaire and PTSD Checklist-Civilian Version (PCL-C). The factors associated with the occurrence of PTSD were also analyzed.</p><p><b>RESULTS</b>The incidence rate of PTSD in the subjects was 8.3%. The PTSD rate of special service corps (12%) was significantly higher than that of other subjects (P<0.05). The incidence of PTSD was highest in the rescuers and firefighters above the third rank, but without significant differences (P>0.05). The PTSD rate of married rescuers and firefighters was significantly higher than that of unmarried subjects (P<0.05). The PTSD rate of subjects addicted to drinking was significantly higher than that of non-drinking subjects (P<0.05). Subjects with more frequent attendance were more susceptible to PTSD compared with those with less attendance.</p><p><b>CONCLUSION</b>The incidence rate of PTSD is high in rescuers and firefighters who have attended rescues. It is necessary to implement both short-term and long-term counseling programs for stress management and intervention in order to reduce the psychological trauma after rescue and improve the mental health of rescuers and firefighters.</p>
