AIDS, which is characterized by an acute infection by HIV and a latent period in which HIV can be transmitted, followed by severe disease, is an example of a “new” zoonotic viral disease. In humans, virus spread is often the result of behavioral patterns of infected individuals during HIV's long latent period. This pattern of spread makes it unlikely that there is any selective pressure over time toward amelioration of the late severe symptoms of AIDS.
