What do you think would happen if a person is infected with zika virus and had a weakened immune system?

The individual with the weakened immune system most likely wouldn’t be able to produce enough antibodies to fight of the virus, especially if they’ve never been exposed to it before. They would most likely succumb to the disease due to a lack of white blood cells and antibodies.

answer: - b cells

explanation: -

there are many types of white blood cells present in our body. one such class of white blood cells are the lymphocytes. the b cells belong to the lymphocyte class of wbcs. the b cells perform their action against the pathogen by producing specialised proteins called as antibodies. these antibodies are produced as and when the b cells encounter pathogens in response to the antigens present on the surface of the pathogen. these antibodies bind to the antigens present on the pathogen and then, target them for destruction by other cells of the immune system.

so, the b cells mediate their action by identifying the antigens present on the surface of the pathogens and then producing antibodies in return to mediate its effect.
