Herd Immunity/Herd Infection: Cultural Artifacts of Marginalization and the Dynamics of AIDS
We examine social conditions under which high prevalence of infectious disease can become endemic within a community, in effect constituting a state of ‘herd infection’ inverse to epidemiological herd immunity. For something like AIDS, under such a circumstance, a single behavioral lapse or adverse accident will probably be a death sentence.

متن کاملInterleukin-5 is essential for vaccine-mediated immunity but not innate resistance to a filarial parasite.
The study of protective immune mechanisms effective against filarial nematodes has been hampered by the inability of these important human pathogens to infect laboratory mice. Recently, Litomosoides sigmodontis, a natural parasite of rats, has been developed as a valuable model for the study of filarial infection. BALB/c mice are fully susceptible to infection with L. sigmodontis third-stage la...
