Final answer:
The main agencies involved in spreading germs are individuals, surfaces, and foods.
Step-by-step explanation:
The main agencies involved in the spreading of germs are:
- Individuals: Germs can be spread through direct contact with infected individuals. For example, if a person with a contagious illness sneezes or coughs near someone else, the droplets containing the germs can enter the other person's body.
- Surfaces: Germs can also be spread through contaminated surfaces. If a person touches a surface that has been touched by someone with germs on their hands, they can then transfer those germs to their own body by touching their face or mouth.
- Foods: Foodborne illnesses can be caused by germs contaminating food. This can happen at any stage of the food production and handling process, from the way foods are grown and processed to the way they are shipped and stored.
It is important to practice good hygiene, such as washing hands regularly, to prevent the spread of germs.
