Influenza H3N2v Virus Ohio Cases
- Two children who had direct contact with swine at the Clark County Fair (July 22-29) have tested positive for a variant swine influenza (flu) virus known as H3N2v, and the Clark County Combined Health District investigated the cases with support from the Ohio Department of Health. Neither child required hospitalization.
- Symptoms and severity of the H3N2v virus are similar to seasonal flu viruses.
- The Centers for Disease Control and Prevention also is reporting two H3N2v cases in Michigan. The Ohio and Michigan cases are not linked. They are the first H3N2v cases reported in the U.S. in 2016. There were three H3N2v cases reported in the U.S. in 2015.
- Flu viruses that commonly circulate in pigs are called “variant” viruses when they are found in people.
- Swine flu viruses do not usually infect people, but rare human infections have been reported, usually after direct or indirect contact with swine such as during agricultural fairs.
- Person-to-person spread of the H3N2v virus is rare, and no sustained or community spread has been identified to date.
- The Ohio Department of Agriculture works with fair boards each year to make sure that information about the H3N2 flu virus is a prominent component of training conducted during their annual meeting, during which they are encouraged to post signage about the importance of good hand hygiene when around fair animals, especially swine.
- Swine flu viruses do not cause foodborne illnesses and have not been shown to be transmissible to people through eating or proper handling of pork meat or other products derived from pigs, according to the U.S. Department of Agriculture.
