I WONDER - How Does The Immune System React When I Am Unwell?

The transcript explains how the immune system responds to infections by causing a fever. A fever is not the infection itself but a mechanism to increase body temperature, making it difficult for viruses and bacteria to survive. Once the fever subsides, the immune system has eliminated the harmful bacteria, leading to recovery.

• To fight off the infection

• To directly cause the infection

• To make you feel tired

Why does the body increase its temperature during an infection?

• To make you feel uncomfortable

What happens to viruses and bacteria in a harsher environment created by fever?
