What is hygiene?
Hygiene is a collective term for everything you do that minimises your contact with pathogens, such as bacteria and viruses (such as SARS-CoV-2). That includes washing your hands, taking a shower, and keeping your kitchen clean. Sometimes it is also necessary to disinfect after cleaning. Read more about hygiene on this page (in Dutch only).
Clean hands are important
Washing your hands regularly ensures that your hands are clean and removes pathogens. This prevents you from spreading pathogens that can make you sick via hand contact.
When should you wash your hands?
In any case:
- after an activity outside the home (such as shopping or playing outdoors)
- before preparing food
- before eating food
- after going to the toilet
- after contact with animals
- when caring for someone who is ill.
What is disinfection?
Disinfection kills pathogens (micro-organisms such as viruses, fungi, bacteria and parasites that can cause illness). It is primarily needed in places where there is a high risk of becoming ill, such as in a hospital. Disinfection is not necessary at work, at school or at home, unless advised by a doctor, GP, Municipal Public Health Service (GGD) or RIVMNational Institute for Public Health and the Environment .
Disinfectants are usually mixtures of one or more active ingredients and one or more excipients (auxiliary materials). Active ingredients render the micro-organisms harmless. It is important to only use disinfectants when absolutely necessary. Pathogens can become less sensitive to the disinfecting substance, making it increasingly difficult to kill the pathogens.
Clean or disinfect?
You can clean surfaces effectively using soap and water or an all-purpose cleaning product. Examples include door handles, counters, display shelves, shopping carts and baskets, and school and office furniture. Proper cleaning reduces the risk that pathogens will get inside you. Cleaning removes pathogens. This reduces the chance that you will get them on your hands. Examples of cleaning products are cleaning wipes, soap or all-purpose cleaner.
It is not necessary to use disinfectants at home. If you clean with cleaning wipes or all-purpose cleaner, that is sufficient. Moreover, if used incorrectly, disinfectants can be harmful to the environment and to human health. And pathogens could become insensitive to a disinfectant if you use it often. In that case, the disinfectant will stop working. Read more about household cleaning and disinfection (in Dutch only). Does someone in your home have COVID-19, and do you want to know if you need to start disinfecting? Please contact your family doctor or municipal public health service (GGD) for advice.
Soap and water or hand gel?
The best way to clean your hands is soap and water. This is the best method for removing pathogens. This also applies to dirty or sticky hands. Alcohol-based hand disinfectant or hand gel will not work well on hands that are dirty and sticky. Only use disinfectant hand gel if you will not have a place to wash your hands with soap and water for an extended period of time. In other situations, it is sufficient if you make sure not to touch your face with your hands, and you wash your hands thoroughly with soap and water as soon as you get home.
It is important to use a disinfectant hand gel only if absolutely necessary. If you use it too often, pathogens could become less sensitive to the disinfecting substance. In that case, the disinfectant will not kill the pathogens effectively enough. In some cases, a hand gel does not state on the label that it is a disinfectant. In that case, it has not been proven to be sufficiently effective against pathogens such as the coronavirus SARS-CoV-2. The website of the Dutch Board for the Authorisation of Plant Protection Products and Biocides (Ctgb) contains a list of products that are approved and effective against SARS-CoV-2.
Frequently asked questions
Why are public spaces and outdoor areas not being disinfected?
We do not recommend the use of disinfectants in public spaces and outdoor areas. There is very little risk that someone will be infected via, for example, floors, benches, playground equipment or railings at the public transport station. The risk of becoming ill is even lower if you do not touch your face with your hands. Wash your hands with soap and water right away, as soon as you get home or arrive at your school or work.
It is not necessary to spray disinfectants or to disinfect outdoor furniture, such as playground equipment and bus shelters. It does not offer extra protection and it can be harmful to people and the environment. In addition, pathogens could become insensitive to a disinfectant if you use it often. In that case, the disinfectant will stop working. In large public indoor spaces, such as stations or shopping malls, it is sufficient to clean with soap and water or an all-purpose cleaning product. There are no substances that are permitted for use in the Netherlands for large-scale disinfection of public spaces or outdoor areas by means of spraying or misting.
Can I become ill from the SARSsevere acute respiratory syndrome-CoVcoronavirus-2 virus if I touch or grasp items or surfaces outside the home?
There is minimal risk that you will become ill if, for example, you touch or grasp items or surfaces in a shop or when you are visiting someone. To avoid becoming ill, do not touch your face with your hands and make sure you regularly wash your hands thoroughly. Wash your hands immediately after touching surfaces or items belonging to someone who may (possibly) have COVID-19.
