1998 Wisconsin County Fair Swine Flu Case
In September 1988, a woman was fatally infected with swine influenza virus in Wisconsin. The victim had attended a county fair and visited the display area of the pig barn. Veterinarians at the fair indicated that pigs in the display area had illnesses consistent with swine influenza. (Wells et al., 1991) The case likely acquired influenza infection through direct transmission from pigs at the fair (see additional information about swine influenza and County Fairs).
