About Hygiene & Prevention
Hygiene does not mean trying to remove every microbe from the world. Most microbes are harmless or useful. Good hygiene focuses on reducing the chance that disease-causing organisms move into places where they can cause infection.
Handwashing
Soap and running water help remove microbes from hands.
Learn MoreHow Soap Works
Soap molecules interact with both water and oily materials.
Learn MoreFood Hygiene
Safe handling reduces the chance that harmful microbes reach food.
Learn MoreSafe Water
Clean drinking water is one of public health's greatest achievements.
Learn MoreRespiratory Etiquette
Covering coughs and sneezes reduces the spread of respiratory droplets.
Learn MoreCleaning and Disinfection
Cleaning removes dirt and many microbes, while disinfection uses chemicals or processes to inactivate specific microorganisms.
Learn MoreVaccination
Vaccines can prevent several serious bacterial diseases.

Living in a microbial world is normal.
Learn MoreHandwashing
Rubbing with soap loosens oils, dirt, and microbes from the skin so they can be rinsed away. Public-health guidance commonly recommends washing for about 20 seconds, especially before preparing food and after using the restroom, coughing, sneezing, or caring for someone who is ill.
How Soap Works
One part of a soap molecule mixes with water while another interacts with oils. This helps lift greasy material and microbes from skin. Mechanical rubbing and rinsing are important parts of the process.
Food Hygiene
Common principles include keeping raw and ready-to-eat foods separated, cleaning hands and surfaces, cooking foods appropriately, and refrigerating perishable foods promptly. Exact guidance varies by food and local health authority.
Safe Water
Water treatment can combine filtration and disinfection to remove or inactivate pathogens. Sewage treatment keeps human waste from contaminating drinking supplies and waterways.
Respiratory Etiquette
Using a tissue or the inside of the elbow can help keep droplets off hands and nearby surfaces. Hand hygiene is useful afterward because respiratory germs can spread by contact as well as through the air.
Cleaning and Disinfection
Not every surface needs constant disinfection. High-touch surfaces, food-preparation areas, healthcare spaces, and known contamination may need targeted methods. Product labels explain contact time and safe use.
Vaccination
Vaccines exist for diseases caused by bacteria such as tetanus, diphtheria, pertussis, and some forms of meningitis and pneumonia. Vaccination trains the immune system before exposure to the disease.
Healthy Balance
The goal of hygiene is not a sterile home or body. Everyday environments naturally contain microbes. Effective prevention focuses on known transmission routes and proven practices rather than fear of all bacteria.
