A child was exposed to a disease-causing virus (most likely chicken pox from the Varicella zoster virus) when he was 5 years old
STatiana [176]

Answer: What is expected to happen is that the secondary immune system acts immediately against the virus.

Explanation:

When a virus first enters our body, in order to defend itself, the body must first recognize what the antigen is in order to fight it through <u>antibodies</u>. Once it does it will keep a memory of it that it can use if this virus enters the body again. <u>This will be done through the secondary immune system</u>.

As the body already recognizes the antigen, it knows how to fight it immediately, generating a thousand times the amount of antibodies generated the first time.

Thanks to its memory cells, the virus will remain much less time in the body.
