INFECTION

Germs are disease causing microorganisms. Bacteria and viruses are the most common germs. When germs enter in our body, they attack different parts of the body. They reproduce and increase their number. Germs produce poisonous substance called Toxin. Toxin spreads in our body cells and destroys them. It results in a Disease. This condition is called infection. Sometimes, germs cause an infection to only some particular part of the body like your eyes, lungs, etc. Sometimes, they might effect the whole body causing fever.

HOW DO GERMS ENTER THE BODY..? Different germs enter the bodies in different ways. Many germs enter through mouth. When you eat contaminated food or drinks, germs enter through your mouth. Germs also enter through respiratory system. When people cough and sneeze, germs from their bodies are pushed out into the air. When you breathe in the same air, germs enter your body. Some germs enter through wounded skin. You can catch some diseases if you touch people who have these diseases, or if you use the things that they have used, such as their cups, towels, combs, etc. Some animals like houseflies, mosquitoes, etc. carry germs from one person to another. Such animals are called Vectors.

• Always wash hands before touching the food.

• Always wash hands after using toilet and whenever you touch a sick person.
• Always cover your mouth with a handkerchief while coughing or sneezing.
• Always spit into a separate bin.
• Tap water contains many germs. Boiling the water destroys many germs present in it. Always drink boiled or filtered water.

• Germs can enter through wounds or cuts. So, whenever you have a cut or wound, it is important to clean it immediately and cover it with a clean dressing.

The people who have some infections should not be allowed to cook food and to work in food factories. Always use a new syringe for blood transfusion.

Many bacterial infections can be treated with antibiotics. An antibiotic is a drug which kills bacteria but does not damage the body cells.
