The Hospital acquired infection scenario

 

Many studies    show 

that bio-aerosols (micro-organism 
conglomerates in suspension in 
the air) play an important role on 
the acquisition of infections being 
calculated as responsible for 10 
to 20% of those cases. 
 

The pathogens can be 

sprayed in many ways, via natural 
or forced ventilation system, 
water spray, skin scales released 
by patients and medical staff, 
coughing and sneezing . Studies also show that surgical 
staff  members  can  liberate  between  1,500  to  50,000        
bacteria per minute and those pathogens may stay in 
suspension in the air for long periods of time. Studies reveal 
that 80 to 90% of all surgical wound infections are related to 
bad air quality and that cleaner air translates into in lower 
infection risk.

 

Studies on hospital acquired infections began 

more than 150 years ago with Ignaz Semmelweis  and 
Florence Nightingale and contributed to the advance of 
microbiologic  and  prophylactic  actions  in  hospital           
enviroments. Despite the increase of asepsis practices, 
hospital infections are still considered a public health 
concern.
