Why is the immune system so fast to respond to allergens, but take days to fight off a legitimate infection?
In: 5304
In addition to what others said, our body IS fast to respond to infections. You just don’t notice the symptoms for 2-3 days because the infection is being held back. As the pathogen grows and spreads, a larger and larger immune response is generated which gives you the fever, body aches, fatigue, etc. Certain organisms have traits that allow them to beat your immune system long enough to grow while others are destroyed immediately because your immune cells are constantly surveying for infections.
