Final Answer:
False. Because of its less efficient transmission, HIV-2 is less common worldwide compared to HIV-1.
The answer is False.
Step-by-step explanation:
HIV-2 is less common worldwide: This part of the statement is true. HIV-2 is indeed less prevalent globally compared to HIV-1. HIV-1 is the more widespread and dominant strain of the virus.
Less efficient transmission: The statement correctly highlights that HIV-2 has a less efficient transmission to new hosts. This characteristic contributes to its lower prevalence on a global scale. HIV-1 and HIV-2 are two distinct types of the human immunodeficiency virus. HIV-1 is more prevalent globally and is responsible for the majority of HIV infections worldwide. In contrast, HIV-2 is mainly found in West Africa and has a slower progression to AIDS. Understanding the differences in transmission and prevalence between these two types is crucial for developing effective prevention and treatment strategies.
