People who live in institutions, such as a university, school or hospital, are particularly prone to getting any new strain that is circulating. It was a "benign" pandemic, primarily affecting people born after 1950, because the older generation had protective immunity resulting from prior experience with H1N1 strains.

Our obsession with geographic eponyms for a disease 1977 – Russian flu (H1N1).
