I have a few doubts regarding infection.
When a bacteria enters a human body, it doesn't give symptoms immediately. Usually there is a latent/incubation period during which we don't feel the infection.
But what happens during this incubation period? What is the body's response during this time?
Of the possibilities described below, what describes correctly the events during the incubation period?
1) Body identifies the moment any bacteria or germ invaded the body. But the body couldn't mobilize the immune soldiers immediately to make an attack. It always takes some time. This is incubation time.
2) Body cannot identify the miniscule number of bacteria. It identifies the invaders only when they're in significant numbers. So body waits for some time for the germs to grow in number to identify and then attack.
3) Is there any other explanation or state which I am missing?
Also some persons remain carriers (without disease manifestations) of some infection for too long a period. They don't display any symptoms but they're potential candidates for spread of the infection to others.
What happens in the carrier's body? While its immune cells are powerful enough to keep the invaders at bay, what is preventing them from completely eradicating the germs, so that they're no longer carriers also.
So, generally what triggers the immune system's attack on invaded germs and when it happens? And how long does this battle continue?
Can someone clear my doubts?
