general medical gloves are basically useless for laboratory acquired infection

At present, there are about 5 million clinical laboratory workers around the world. The workers in these places will be exposed to some health risks. Clinical microbiology laboratory workers, especially the key susceptible population, because they are most likely to be infected with microbial acquired infection

it is still difficult to accurately measure the risk of Lais, because we are unable to determine the source of its transmission. Early investigations have shown that laboratory technicians are nine times more likely to be infected with Mycobacterium tuberculosis than the general population. Some scholars have shown that the probability of laboratory acquired pathogens infection among the staff of hospital microbiology laboratory is about 0.18-3.5 per 1000 people. However, there is still no monitoring system for Lais. The center for Disease Control and Prevention recently stressed that more than 40% of laboratory acquired pathogen infections are caused by bacteria. Baron and Miller reported that Shigella, Brucella, Salmonella, Staphylococcus aureus and Neisseria meningitidis were the most common pathogens

there may be five ways of transmission of pathogenic bacteria in clinical laboratory: sharp instrument injury, leakage or splashing on skin and mucous membrane, ingestion of digestive tract, animal bite and scratch, and inhalation of infectious aerosol. However, only 20% of Lais have a clear route of transmission. Therefore, it is particularly important for us to record the route of transmission of pathogens and identify the security measures that may have loopholes in order to improve the prevention and control mechanism and reduce laboratory acquired pathogen infection

the infection control department should take additional measures to improve the safety standards, so as to avoid the health hazards from the laboratory environment. We should make full use of the natural environment of clinical laboratory, including sufficient space, ventilation and lighting. As a result, the clinical laboratory standards association has published a guideline detailing the best architectural and organizational planning for diagnostic laboratories

the key is to use and wear proper personal protective equipment and wash hands. However, unlike clinical departments, alcohol products are generally not used to disinfect hands in diagnostic laboratories, because they should try to avoid chemical pollution. Therefore, people are more likely to accept washing hands and brushing hands with ordinary soap, which can avoid biological and chemical hazards. Laboratory staff must wash hands immediately after taking off gloves, with obvious stains, after completing work, before leaving the laboratory or before contacting clean skin, eyes and mucous membrane

at present, we have reported a clinical biologist whose hand was infected by microorganisms from the laboratory environment. We are committed to the archive of isolated strains, especially the recently preserved strains. 1n the end, we can conclude that the PFGE profiles of the strains from patients stored for three days match the PFGE profiles of the strains isolated from their wounds. Our further study on the biosafety measures that may have loopholes and the route of transmission of pathogens found that this may be due to the back of the hands of their hands touching the contaminated glove surface. The qualitative analysis of his hand surface trauma can verify this view. The patient used gloves at work, but he may not wash his hands after work and after removing gloves. Therefore, we emphasize that laboratory staff should be regularly trained on occupational safety protection and management measures, and ensure that the staff can always adhere to these measures
