Question

PLS I need help with this question, ASAP

Answer 1

I found this answer on Wiki, but I can further explain it if it does not make sense.

Poliovirus uses two key mechanisms to evade the immune system. First, it is capable of surviving the highly acidic conditions of the stomach, allowing the virus to infect the host and spread throughout the body via the lymphatic system.^[3] Second, because it can replicate very quickly, the virus overwhelms the host organs before an immune response can be mounted.^[57] If detail is given at the attachment phase; poliovirus with canyons on the virion surface have virus attachment sites located in pockets at the canyon bases. The canyons are too narrow for access by antibodies, so the virus attachment sites are protected from the host's immune surveillance, while the remainder of the virion surface can mutate to avoid the host's immune response.^[58]
