Editor's Notes
- A bedridden patient colonized with Gram-positive cocci, in particular at nasal, perineal, and inguinal areas (not shown), as well as axillae and upper extremities. Some environmental surfaces close to the patient are contaminated with Gram-positive cocci, presumably shed by the patient.
- Contact between the HCW and the patient results in cross-transmission of microorganisms. In this case, Gram-positive cocci from the patient’s own flora transfer to HCW’s hands
- Microorganisms (in this case Gram-positive cocci) survive on hands. Reprinted from Pittet, 2006885 with permission from Elsevier. (B) When growing conditions are optimal (temperature, humidity, absence of hand cleansing, or friction), microorganisms can continue to grow.
- Inappropriate handwashing can result in hands remaining contaminated
- The doctor is in close contact with the patient. He touched the urinary catheter bag previously and his hands are contaminated with Gramnegative rods from touching the bag and a lack of subsequent hand cleansing. Direct contact with patients or patients’ devices would probably result in cross-transmission.
