It is totally inaccurate and misleading to use the term “generalized” to describe any HIV epidemic since only persons who are exposed to HIV-infected blood or sexual fluids such as semen are at any risk of an HIV infection! When HIV prevalence is >1% of any specific population, the more accurate term is extensive - NOT generalized!

Even in sub-Saharan Africa, the epicenter of the HIV/AIDS pandemic, HIV cannot be considered a generalized infection since the majority of all "general" populations are not infected with HIV and are not at significant risk of acquiring HIV infection via sexual intercourse because they are either abstinent or they and their regular sex partner are mutually monogamous or faithful to each other!
Virtually every man, women, and child are assumed to be at risk of infection with a pandemic influenza virus and in all documented influenza pandemics, the majority of the total population were infected. Influenza epidemics can be accurately called "generalized"epidemics, but HIV is not capable of causing a "generalized" epidemic!
