Macau: Seasonal influenza transmission continues, although the number of influenza-like illness cases in emergency departments of hospitals has decreased in the week ending 5 August 2017. Influenza A(H3) accounts for 98.2% of confirmed influenza.
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.
