One of the most cost-effective disinfectants used is chlorine bleach (a 5% solution of sodium hypochlorite), which is effective against most common pathogens, including difficult organisms found in a healthcare setting, such as antibiotic-resistant strains of staphylococcus, fungi, and hepatitis B and C. Disinfection does not necessarily kill all microorganisms, especially resistant bacterial spores; it is less effective than sterilisation.
