2017 Novel Influenza A Case in the U.S.
The below information was shared from the CDC in regards to the first local case of novel influenza A virus (H3N2v) detected in 2017:
“One human infection with a novel influenza A virus was reported by the state of Texas. The person was infected with an influenza A (H3N2) variant (H3N2v) virus. This H3N2v virus was detected through the Department of Defense Global, Laboratory-based Influenza Surveillance Program. The patient became ill with respiratory symptoms in February 2017, was not hospitalized, and has fully recovered from their illness. Swine contact at an agricultural event was reported in the week preceding illness onset. This is the first H3N2v virus infection detected in the United States in 2017.
Influenza viruses that circulate in swine are called swine influenza viruses when isolated from swine, but are called variant influenza viruses when isolated from humans. Early identification and investigation of human infections with novel influenza A viruses are critical so that the risk of infection can be more fully understood and appropriate public health measures can be taken. Additional information on influenza in swine, variant influenza infection in humans, and strategies to interact safely with swine can be found at http://www.cdc.gov/flu/swineflu/index.htm.”
Symptoms of uncomplicated influenza include fever, chills, cough, upper respiratory tract symptoms, headache, sore throat, myalgias, arthralgias, fatigue, vomiting, and diarrhea. Novel influenza A strains have been frequently associated with conjunctivitis. Please assess any suspect cases of novel influenza for animal and travel exposures in the 10 days prior to symptom onset.
Novel influenza is immediately reportable 24/7 by phone upon initial clinical suspicion or laboratory test order to the Florida Department of Health in Pinellas County (DOH-Pinellas). To report a case of novel influenza or to ask any questions, please contact DOH-Pinellas at 727-824-6932.
