Käsidesinfektiota

Käsidesinfektiota is the Finnish term for hand disinfection. It refers to the process of reducing or killing microorganisms on the hands through the use of chemical agents. This is a crucial practice for preventing the spread of infections, particularly in healthcare settings and public spaces.

The most common active ingredients in hand disinfectants are alcohol-based solutions, typically containing ethanol or isopropanol at concentrations between 60% and 80%. These alcohol-based products work by denaturing proteins essential for microbial survival. Other types of disinfectants may contain quaternary ammonium compounds or chlorhexidine, though alcohol-based options are generally preferred for their efficacy and rapid action on the hands.

Proper hand disinfection technique involves applying a sufficient amount of disinfectant to cover all surfaces of the hands and rubbing them together until dry. This includes the palms, back of the hands, between the fingers, under the nails, and the wrists. The friction generated during rubbing also plays a role in the removal of transient microorganisms.

Hand disinfection is distinct from hand washing with soap and water. While soap and water are effective at physically removing dirt and a broad spectrum of microbes, hand disinfection is specifically designed to kill or inactivate pathogens. Hand washing is recommended when hands are visibly soiled or after contact with bodily fluids, whereas disinfection is often used when soap and water are not readily available or as an additional measure after washing. Widespread and correct use of hand disinfection is a cornerstone of infection control.
