Two cases of influenza A (H1N2) variant virus infection have been lab-confirmed in persons who had pig exposure at the California Mid-State Fair in Paso Robles, CA (July 17 to 29, 2018). Person-to-person transmission of variant influenza viruses is rare. Health care providers should ask patients presenting with influenza-like illness this summer whether they attended a state or county fair within 7 days of illness onset, were otherwise directly or indirectly exposed to pigs, or had close contact with an ill person who had recent pig exposure or is known to have H1N2. If infection is suspected with a patient, clinicians should immediately notify their local public health department. To learn more, go to https://bit.ly/2L9B98s .
