Final answer:
The statement regarding differing HIV viruses in AIDS patients is true due to the high mutation rate of the virus. HIV has high genetic variability, making it different in each individual, which poses challenges for treatment and vaccine development. Treatment discrepancies also exist globally, affecting management of the disease.
Step-by-step explanation:
The statement that no 2 AIDS patients carry the identical virus can be considered true due to the high mutation rate of the HIV virus, which is the virus that causes AIDS. Human Immunodeficiency Virus (HIV) has two main variants, HIV-1 and HIV-2, with HIV-1 being the most common worldwide. As HIV replicates within a patient's body, it can mutate frequently leading to genetic variability.
This means that the virus can differ slightly from person to person, although they are all HIV viruses. It's this genetic diversity that contributes to the challenges in creating a vaccine and the need for a combination of antiretroviral drugs to effectively manage the disease. Moreover, treatment with antifungal medications does not reduce the viral load in patients with HIV, as these drugs target fungi and not viruses. It is also true that different types of sexual intercourse have different risks of transmitting HIV. In terms of prevention and treatment, while significant advances have been made in the management of HIV, disparities exist globally in terms of access to these life-saving medications.
