Avian Influenza A(H7N9) Virus Antibodies in Close Contacts of Infected Persons, China, 2013–2014 (http://wwwnc.cdc.gov/eid/article/21/4/14-1442)

摘要

From early 2013 ( 1 ) through November 2014, >460 human cases of laboratory-confirmed avian influenza A(H7N9) virus infection occurred in China. Although human-to-human transmission of subtype H7N9 virus is not common, evidence has been reported of probable transmission among several family clusters ( 2 ), between 2 household contacts ( 3 ), and between a doctor and an infected patient ( 4 ). Taken together, these observations suggest that family members, health care providers, and other close contacts (hereafter called contacts) of H7N9-infected persons may be at risk for infection.
