Abstract:
Abstract: Objective To collect the cases of laboratory-acquired infections (LAI) reported in literatures in China, summarize the infection routes and causes of LAI in China, in order to improve laboratory staff's understanding of its occupational health and safety risks. Methods The cases of laboratory-acquired infection reported in domestic literatures were collected from PubMed, CNKI, Wanfang Database, CBM China Biomedical Literature Database up to April 11, 2022, retrospectively analyze the number and causes of LAI reports, the main risk factors of LAI and its harm to society, the consequences of LAI or the leakage of pathogenic microorganisms, and put forward the relevant countermeasures of biological safety. Results A total of 22 LAI reports were collected, reviewed and integrated into 21 reports. There were 7 kinds of pathogenic microorganisms. The main pathogenic microorganisms were hantavirus (42.86%, n=9) and Brucella (33.33%, n=7). There were 122 cases and 3 deaths in the laboratory. Most of the reports came from research laboratories (66.67%, n=14). The main route of infection was inhalation of aerosol (42.86%, n=9), followed by transdermal route (38.09%, n=8). Conclusions Failure to report LAI events will increase the risk of pathogenic microorganisms spreading to people outside the laboratory and the environment through infected laboratory staff. Local health institutions and laboratories should be encouraged to report LAI cases as a powerful tool for monitoring accidental leakage of pathogenic microorganisms and further improving laboratory biosafety. The laboratory needs strong biosafety measures to protect staff's health and prevent environmental pollution caused by accidental leakage of pathogenic microorganisms.
