What are the risks of not washing hands after using the toilet?

Under normal circumstances, the risks of not washing hands after using the toilet include spreading pathogens, parasitic infections, food contamination, self-infection, and cross-infection. The details are as follows:

1. Spreading Pathogens

Feces contain numerous pathogens such as Escherichia coli, Salmonella, norovirus, and others. If hands are not washed, these pathogens may remain on the hands and be transmitted to others through touching objects or shaking hands, leading to the spread of bacteria and viruses and causing infectious diseases.

2. Parasitic Infections

Diseases caused by parasites, such as roundworms and hookworms, can be transmitted via the fecal-oral route. If hands are not washed after contact with infected feces and then touch the mouth or food, parasitic infection may occur.

3. Food Contamination

Touching food with unwashed hands after using the toilet may transfer bacteria and viruses from the hands to the food, resulting in food contamination. Consuming contaminated food may lead to food poisoning, gastrointestinal infections, and other illnesses.

4. Self-Infection

If, without washing hands, one touches mucous membranes such as the mouth, nose, or eyes, bacteria and viruses on the hands may enter the body, causing self-infection. This could lead to respiratory or gastrointestinal infections.

5. Cross-Infection

Shaking hands with others or touching public items with unwashed hands may transmit bacteria and viruses to others, resulting in cross-infection. Particularly during peak disease seasons, such as flu season, failure to wash hands may exacerbate the spread of illness.

In daily life, developing good handwashing habits is essential for effectively preventing the spread of diseases and maintaining personal hygiene.
