After the incubation stage comes the prodromal stage, which is a short period of time where someone feels mildly ill but has not yet developed a fulminant illness.

How does your body know you have an infection?

Antibodies. Antibodies help the body to fight microbes or the toxins (poisons) they produce. They do this by recognising substances called antigens on the surface of the microbe, or in the chemicals they produce, which mark the microbe or toxin as being foreign.
