Germs are everywhere. Without realizing it, our hands spread germs to other people, to other places or even enter the germs into our own bodies such as when touching our mouth with dirty hands. Not washing hands properly can increase a person's chances of getting the disease.

We already know that hands are a medium of transmission disease, because hands make direct contact with various objects or areas that contain a lot of disease-causing bacteria, especially in this case Salmonella bacteria.

Salmonella infection can also occur if someone touch, kiss, or pet animals such as cats, dogs and birds, which are infected with Salmonella. A person is susceptible to infection if he does not wash his hands after handling the animal or touching its feces.

If someone don't wash hands, Salmonella bacteria will remain on a person's hands, spread to various places, and food that is touched with hands will be contaminated by these bacteria. Salmonella bacterial infection is one of the causes of typhoid fever. Eggs from salmonella bacteria will then move into the digestive tract, causing infection with symptoms such as cold sweat, nausea, vomiting and diarrhea.
