Question

When infected by a pathogen, we tend to get a fever. What is the primary reason for this?

• A. To kill the pathogens
• B. Breakdown of body system
• C. To increase the growth rate of pathogens
• D. Result of infection

Answer 1

The correct option is A To kill the pathogens

• Our body has many mechanisms to fight infections of which, fever is one of them.
• Bacteria and viruses can survive only within a very small range of temperatures. So by raising the body’s temperature, their growth is inhibited and can be easily destroyed.
• Fever also activates the body’s immune system to make more white blood cells, antibodies, and other infection-fighting agents.
