Why is a coinfection not possible when it’s the regular bug versus the new bug in the same host?
In: Biology
Microbes enter your body quite often, but the immune system is basically killing them pretty fast. You actually get sick once the microbes manage to entrench themselves and evade the immune system, and then multiply exponentially. Once that happens, the exponential numbers of microbes can overwhelm the immune system, and the typical symptoms you have (fever, runny nose, etc.) are the immune system cells also increasing their numbers to “fight” the high number of microbes.
So a few numbers of a second bug entering your body at a time when the immune cells are increased numbers because they’re fighting the first bug, is like trying to solo vs. an army of 100,000 soldiers.
You have to be more specific.
A coinfection is absolutely possible, and even common. But sometime a microbe can consume all the “food” or Simply already occupy the space needed by the second microbe, making you resistant to the second infection.
