What is the most common cause of laboratory-acquired infection?
Of the common blood-associated viruses, hepatitis B virus (HBV) is the most common cause of laboratory-acquired infection [1].
What are laboratory-acquired infections?
Laboratory-acquired infections (LAIs) are defined as all infections acquired through laboratory activities, regardless of their clinical or subclinical manifestations. Biosafety guidelines have evolved from the efforts of the microbiological and biomedical communities to reduce LAIs.
What significant measures will you place in your lab to prevent LAIs?
Eating, drinking, smoking, applying cosmetics or storing food for human consumption in laboratories is strictly prohibited. Potentially contaminated hands should be kept away from the mouth, eyes, and non-intact skin.
How can you minimize the infection in the laboratory worker?
Wash hands following all laboratory activities, following the removal of gloves, and immediately following contact with infectious materials. Decontaminate work surfaces before and after use, and immediately after spills.
What are the common routes of exposure to microorganisms or infection in the laboratory?
The most common routes of infection are inhalation (particularly by aerosols), percutaneous inoculation (needlestick injuries, broken glass injury, and/or animal bites or scratches), direct contact between contaminated surfaces (gloves, hands), and mucous membranes as well as through ingestion – for example by smoking.
What diseases do labs have?
List of laboratory biosecurity incidents
| Date (yyyy-mm-dd) | Main article | Pathogen |
|---|---|---|
| 1977–1979 | 1977 Russian flu | H1N1 influenza virus |
| 1978-08-11 | 1978 smallpox outbreak in the United Kingdom | Smallpox |
| 1978 | Plum Island Animal Disease Center#Laboratory accidents | Foot and mouth disease |
| 1979-04-02 | Sverdlovsk anthrax leak | Anthrax |
What are the types of hospital-acquired infection?
CDC works to monitor and prevent these infections because they are an important threat to patient safety.
- Central Line-associated Bloodstream Infection (CLABSI)
- Catheter-associated Urinary Tract Infections (CAUTI)
- Surgical Site Infection (SSI)
- Ventilator-associated Pneumonia (VAP)
What are the techniques and procedures to minimize infection in a clinical laboratory?
Use of personal protective equipment (e.g., gloves, masks, eyewear). Respiratory hygiene / cough etiquette. Sharps safety (engineering and work practice controls). Safe injection practices (i.e., aseptic technique for parenteral medications).
What elements of laboratory safety are necessary for infection prevention and control?
What elements of laboratory safety are necessary for infection prevention and control? An adequate laboratory infrastructure and an implemented bio-risk management system form the basis of prevention and control in the laboratory setting. Only a small number of LAI involved a specific incident.
Why is infection control important in laboratory?
Infection control is concerned with preventing nosocomial or healthcare-associated infections . Surveillance, which is an essential element of an infection control program, provides the data to identify infected patients and determine the site of infection and the factors that contributed to the infection .
What are laboratory acquired infections (Lais)?
Introduction Laboratory-acquired infections (LAIs) are defined as all infections acquired through laboratories or laboratory-related activities, whether they are symptomatic or asymptomatic in nature. LAIs due to a wide variety of bacteria, viruses, fungi, and parasites are described in the literature.
What are the strategies for the prevention and management of laboratory infections?
Strategies for the prevention and management of laboratory-associated infections are based on the containment of the infectious agent by physical separation from the laboratory worker and the environment, employee education about the occupational risks, and availability of an employee health program.
Laboratory-acquired infections due to a variety of bacteria, viruses, parasites, and fungi have been described over the last century, and laboratory workers are at risk of exposure to these infectious agents.
How common are laboratory-acquired infections in Biosafety Level 3 labs?
The majority of the LAIs (73 %) occurred in a biosafety level 3 laboratory in the context of microbiology activities (42 %), followed by microscopy (22 %) and cell culture (22 %) (Fig. 3).
