Discuss how carriers transmit disease from infected to healthy human? Explain in your own words.

Explanation

**Step-by-Step Solution:**

1. **Understanding Carriers**: Carriers are organisms that can transmit diseases from one host to another without necessarily being affected by the disease themselves. They play a crucial role in the spread of infectious diseases.

2. **Transmission through Air**: Diseases can be transmitted through the air when an infected person coughs or sneezes. For example, tuberculosis and common cold are spread this way. The droplets released into the air contain germs, and if a healthy person inhales these droplets, they can become infected.

3. **Transmission through Food and Water**: Contaminated food and water are another common way diseases are spread. This contamination often occurs due to flies or dust that come into contact with garbage and then transfer germs to food. When a person consumes this contaminated food or water, they can contract diseases such as cholera and typhoid.
