State and federal officials are investigating the cause of a confirmed case of a variant of the swine flu on Maui.
The state Department of Health said Tuesday multiple agencies are working to find out how the Maui adult contracted the H3N2v virus.
Lab results were confirmed for the H3N2v virus last week after the adult sought medical attention for fever, cough and body aches. The Maui resident has since fully recovered without needing to be hospitalized.
The Centers for Disease Control and Prevention says since August 2011, a number of U.S. residents were found to be infected with influenza A variant viruses, primarily H3N2v. Infections occurred after contact with swine as well as limited human-to-human transmission.
It's recommended that those who work closely with pigs to take protective measures.
