Past, Present, and Possible Future Human Infection with Influenza Virus A Subtype H7

摘要: Influenza A subtype H7 viruses have resulted in >100 cases of human infection since 2002 the Netherlands, Italy, Canada, United States, and Kingdom. Clinical illness from ranges conjunctivitis to mild upper respiratory pneumonia. Although infections a smaller proportion hospitalizations deaths humans than those caused by H5N1, some strains appear more adapted for on basis their virus-binding properties rates among exposed persons. Moreover, increased isolation influenza poultry ability this cause severe disease underscore need continued surveillance characterization these viruses. We review history H7. In addition, we discuss recently identified molecular correlates virus pathogenesis assess current measures prevent future infection.
