2.2 CROSS INFECTION CONTROL

What Is A Cross Infection?

A cross infection is the transfer of harmful microorganisms, usually bacteria and viruses. The
spread of infections can occur between people, pieces of equipment, or within the body.

These infections can cause many complications. So, medical professionals work hard to ensure
equipment safety and a clean environment.

Causes Of Cross Infection

Cross infections can be caused by:

• bacteria

• fungi

• parasites

• viruses

These microorganisms can be transmitted by:

• unsterilized medical equipment

• coughing and sneezing

• human contact

• touching contaminated objects

• dirty bedding

• prolonged use of catheters, tubes, or intravenous lines

The risk for infection is greater when undergoing a medical procedure. But cross infection can
happen within the body. An infection in one part of the body can spread to another, like a
respiratory infection spreading to the ears or eyes.

Treating Cross Infection

Treating a cross infection depends on the condition. Antibiotics are used for bacterial, fungal,
and parasitic infections, but not for most viral infections.Over time, bacteria can adapt and
become resistant to medications. This leads to the evolution of “superbugs.” These are strains of
bacteria immune to multiple antibiotics. This can make them more difficult to kill, and can
increase complications.
