Influenza A(H1N1)pdm09 Virus Infection in a Captive Giant Panda, Hong Kong

Emerg Infect Dis. 2019 Dec;25(12):2303-2306. doi: 10.3201/eid2512.191143.

Abstract

We report influenza A(H1N1)pdm09 virus infection in a captive giant panda in Hong Kong. The viral load peaked on day 1 and became undetectable on day 5, and an antibody response developed. Genome analysis showed 99.3%-99.9% nucleotide identity between the virus and influenza A(H1N1)pdm09 virus circulating in Hong Kong.

Keywords: Hong Kong; giant panda; influenza; influenza A(H1N1)pdm09; respiratory infections; viruses.
