How do HAI’s spread?
Infectious bacteria can survive under the right conditions in hospitals and health care facilities for weeks, and months.
Tests have even shown that some MRSA bacteria have been revived after surviving one year in a dusty hospital environment. The bacteria live and grow on bedrails, curtains, call buttons, door handles – all possible surfaces, even radiators. They spread easily in dirty environments through the so-called cross-contamination phenomenon.
Cross-contamination means that bacteria are passed from one patient to another through contaminated items in the health care environment. When these items are touched by a person, the bacteria are transferred to this person, who then transfers them on to the next item or person he or she touches and so on.
