H7N9 antibody study finds no sign of infection in contacts of Taiwan's only H7N9 case to date...

Hseih and colleagues describe, in the Journal of Infection, their a study to find antibodies made in response to infection by influenza A(H7N9) virus among any of the 14 close contacts  of the only H7N9 case outside of mainland China, in Taiwan.

None of the contacts had influenza-like illness (ILI) during a 28-day monitoring period and none had had significant levels of antibody.

The authors conclude that human-to-human H7N9 transmission risk is low, based on these 14 cases.
