We conducted a serologic study of domestic cats near the epicenter of the dairy cattle outbreaks of influenza A(H5N1) in California, USA. Three of the 12 cats sampled within 2 km of farms had neutralizing antibodies against H5N1 virus. Proximity to dairy farms was a statistically significant risk factor for seropositivity.
Neutralizing antibodies to H5N1 were detected in 3 of 12 domestic cats sampled within 2 km of dairy farms in California, USA.
