Summer influenza spike

There has been a spike in influenza (flu) cases during the summer months this year. While most of us would expect the flu to hit in winter, there can be cases all year round.
This years spike is unusual – in some parts of Australia the numbers have been 3 times what they usually are. Most of these cases stem from travellers returning from Asia and the northern winter, having caught it over there.

Influenza remains one of the most common vaccine preventable illnesses for travellers and this recent spike highlights how important influenza vaccine is for travellers, regardless of age and time of year.
