When learning about HIV/AIDS, the student should be able to differentiate the two subtypes of virus by ____
A) Means of transmission
B) HIV-1 is more prevalent than HIV-2 subtypes
C) The fact that it is a mutated virus originally thought to be bovine in nature
D) Cure rate of the virus
B
Feedback:
Two HIV subtypes have been identified: HIV-1 and HIV-2 . HIV-1 mutates easily and frequently, producing multiple substrains that are identified by letters from A through O. HIV-2 is less transmittable, and the interval between initial infection with HIV-2 and development of AIDS is longer. HIV-1 is more prevalent in the United States and in the rest of the world. Western Africa is the primary site of infection with HIV-2 . There is no cure for HIV/AIDS; hence, no cure rate. The virus is thought to be a mutation of a simian virus. Transmission of the virus is not a characteristic.
