Blood and Body fluids, and Their Risk of Infection
Route of infections:
- There are so many body fluids including the blood which are infectious and hazardous for human beings and particularly people working in the laboratory.
- These biological hazards expose unprotected laboratory workers to bacteria, viruses, parasites, and some other biological agents.
- This infection may be from ingestion, inhalation, inoculation, or tactile contacts. There may be inhalation of the infectious material from the patient or their body fluids/tissues.
The source of contamination may be from:
- Contaminated laboratory equipment.
- Improperly processed blood products.
- Inappropriate disposal of laboratory waste products.
- The potentially infectious body fluids are:
- Bloody fluids.
- Pleural fluid.
- Pericardial fluid.
- Peritoneal fluid (ascites).
- Amniotic fluid.
- Cerebrospinal fluid.
- Vaginal secretion s.
- Saliva in a dental procedure.
- Synovial fluid.
- Pus and purulent discharge.
- Tissue biopsy or organ which is unfixed.
- Noninfectious material is:
- Nasal secretion.
- Stool. Tears.
