I. Frequent mutations in genes for surface proteins help a virus evade the immune system by altering its antigens, making it harder for the immune system to recognize and attack the virus. II. Building the viral shell from host proteins can help the virus avoid detection by the immune system because the viral shell will mimic the host's own cells. IV. Infecting and killing helper T cells directly undermines the adaptive immune response by eliminating a key component of the immune system that helps coordinate the attack against pathogens.
