Question

Quizplus · Accepted Answer

Your friend acquired flu-like symptoms because they did not have previous exposure to the virus and did not have adaptive immunity to it. This allowed the virus to infect and cause illness. On the other hand, you may have been previously exposed to the virus or have innate immunity, which protected you from developing flu-like symptoms.
