The term “carrier” refers to a patient who is still in the latent stage of HIV infection, that is, although the patient is infected with HIV and the virus continues to replicate in his body, his immune function is not particularly poor at this time, so he does not show obvious symptoms and is therefore called a carrier. Although the patient is a carrier, he is still highly contagious and can transmit the virus to healthy people through sexual intercourse, blood and mother-to-child transmission. Therefore, once AIDS is diagnosed, even if you are in the latent stage, that is, a carrier, you should take antiretroviral treatment in time to avoid progressing to the AIDS stage and to avoid infecting more people.
