Seasonal transmission of influenza continues in Taiwan, although in the week ending 5 August 2017 the number of influenza-like illnesses in emergency departments is decreasing. The predominant virus is influenza A(H3N2) with influenza B also present.
Travellers to countries during their influenza season are at similar risk of infection as local residents.
Crowded conditions encourage spread of infection and travellers can be exposed, for example in those attending pilgrimages (e.g. the Hajj), in aircraft, waiting rooms, buses, bars, hotels and on cruises.
Travellers included in the government's at risk groups should ensure that they receive the annual influenza vaccine, particularly if travel is anticipated. Travellers outwith these groups may wish to obtain the vaccine privately (if still available) if concerned.
