What Are Germs?

What are germs?

We are constantly exposed to microorganisms, both good and bad. Most microorganisms we come into contact with during our daily lives are harmless. Some even help keep us healthy. But certain microorganisms-when in the wrong place- can pose real health hazards. We call these harmful microorganisms "germs."

Some exposure to germs can help build up our immune systems, helping us to fight infections and stay healthy. Exposure to others, however, can cause food poisoning, sickness and diarrhea so it makes sense to practice the good hygiene and cleanliness that will prevent these problems.

Examples of microorganisms

• Bacteria: Salmonella bacteria can cause food poisoning.
• Viruses: Rhinoviruses can cause colds. Herpes simplex causes cold sores. Influenza can cause the Flu.
• Fungi: Trichophyton can cause Athlete's foot.
• Parasites: Giardia can cause diarrhea.
