[General] General medical gloves are basically useless for laboratory-acquired infections

At present, there are about 5 million clinical laboratory workers around the world. Staff at these locations are exposed to some health risks. Workers in clinical microbiology laboratories are particularly focused on susceptible individuals because they are most likely to be infected with microbial acquired infections.

It is still more difficult to accurately measure the risk of LAIs because we cannot routinely determine the source of the transmission. Early investigations showed that laboratory technicians were 9 times more likely to be infected with M. tuberculosis. Some scholars have shown that the probability of lab-acquired pathogen infections occurring in hospital microbiology laboratories is approximately 0.18-3.5 infections per 1,000 people. However, there is still no LAIs monitoring system. The Centers for Disease Control and Prevention recently emphasized that more than 40% of laboratory-acquired pathogenic bacterial infections are caused by bacteria. According to Baron and Miller, Shigella, Brucella, Salmonella, Staphylococcus aureus, and Neisseria meningitidis are the most common pathogens.

Clinical laboratory pathogens may be transmitted in the following five ways: sharp injury, leakage or splash to the skin and mucous membranes, digestive tract intake, animal bites and scratches and inhalation of infectious aerosols. However, only 20% of LAIs have a clear route of transmission. Therefore, we record the route of transmission of pathogens and identify potential safety measures. It is particularly important to improve prevention and control mechanisms and reduce laboratory-acquired pathogen infections.

The infection control department should take additional measures to improve safety standards and prevent laboratory workers and other workers from having health hazards from the laboratory environment. We should make full use of the natural environment of clinical laboratories, including adequate space, ventilation and lighting. Therefore, the Clinical Laboratory Standards Association published a guide detailing the best construction and organizational planning for diagnostic laboratories.

The use and wearing of appropriate personal protective equipment and hand washing are key. However, unlike clinical departments, alcoholic products are generally not used to disinfect hands in diagnostic laboratories because they try to avoid chemical contamination. As a result, people are more receptive to washing their hands with ordinary soap and brushing their hands, which can avoid biological and chemical hazards. Laboratory personnel must wash their hands immediately after undressing, with visible smudges, after completing work, before leaving the laboratory, or before touching clean skin, eyes, and mucous membranes.

At present, we have reported a clinical biologist whose hand was infected by a microbe from a laboratory environment. We are committed to the isolation of strains of the archives, especially the recently preserved strains. Ultimately, we can conclude that the strain from the patient's three-day storage matches its PFGE pattern of the wound isolation strain. We conducted further research on possible biosecurity measures and the route of transmission of pathogens that may be flawed. This may be due to the fact that the backs of the hands of both hands are in contact with the surface of the contaminated gloves. The characterization of the wounds on the surface of the hand can test this view. The patient uses gloves during work, but may not wash his hands after he works or after taking gloves. Therefore, we emphasize the need to regularly train laboratory workers in occupational safety protection and management measures and ensure that the staff can always adhere to these measures.
