A simple online survey that takes less than 10 seconds each week during flu season can tell us so much.
On the first visit they provide the following information:
- Month and year of birth
- Receipt of influenza vaccine in the preceding year
- Postcode of residence
- Indigenous status (AU) or ethnicity (NZ)
- Face to face contact with patients (for participants 15 years or older)
- Highest level of education (for participants 15 years or older)
On subsequent weekly visits to the form, they are asked about the presence of typical flu-like symptoms like:
If you answer ‘yes’ to at least one of the symptoms, you’ll get these follow-up questions about:
- Sore throat
- Number of days absent from normal duties
- Visits to health care providers
- Results of laboratory tests for Influenza
- Receipt of influenza vaccine in the current year

The FluTracking Surveillance System in New Zealand
FluTracking launched in New Zealand in May 2018. Over 6,000 people, representing 507 postcodes across North Island and South Island, registered with FluTracking in its first year. There were approximately 4,000 participants per week (or a participation rate of 1 in every 1,200 New Zealanders).

The FluTracking Program in Australia
FluTracking was launched in the Australian winter of 2006 with 400 “FluTrackers” completing a 10 – 15 second online survey about flu-like symptoms each week.
In the winter of 2007 this increased to approximately 800 participants. From 2008 onwards participants were able to answer the survey on behalf of household members; this substantially increased the participation rate to over 1600 people in the winter of 2008.
The number of participants has continued to increase each year, with over 40,000 people answering the survey every year since 2010.
Participation in FluTracking Australia increased by 34% from 2017 to 45,532 participants in 2018

By comparing the rate of symptoms between vaccinated and unvaccinated participants we were able detect when influenza struck because the unvaccinated people had much higher rates of illness than the vaccinated people.
The main aims of FluTracking are to develop a system that can provide:
- Community level influenza-like illness surveillance
- Consistent surveillance of influenza activity across all jurisdictions and over time; and
- Year-to-year comparison of the timing, attack rates, and seriousness of influenza in the community.
2018 Survey Results
2018 fever and cough levels for Australia were the lowest on record in FluTracking data.
You showed us that the 2018 influenza season had lower levels of influenza-like illness activity than recent years, as well as lower levels of associated absenteeism. Collectively FluTrackers had 40,850 days (112 years!) off work or normal duties due to fever and cough symptoms. However, this was much lower than 2017 absenteeism levels.
A burden of illness pyramid is a method for estimating the relationship between influenza-like illness at the community level with national influenza laboratory reports. The figure below describes surveillance levels from cough and fever through to positive laboratory test for influenza (self-reported) among FluTracking participants across Australia, for the four weeks of peak influenza activity beginning week ending 06/08/2017 to 27/08/2017 and 12/08/2018 to 02/09/2018.
One sixth as many FluTrackers tested positive for influenza in 2018, as compared to 2017.
Of our participants that reported fever and cough in 2017 and 2018, there was a lower proportion of participants seeking medical advice for flu-like illness in 2018, as compared to 2017, and a lower proportion of FluTrackers testing positive for influenza in 2018, as compared to 2017.
More than 3 times as many young children were vaccinated in 2018, as compared to 2017.
Vaccination coverage in 2018 was 55.7% in participants aged under five compared to a five year average of 16.2%. Vaccination coverage in 2018 was also higher in older participants, and markedly so in the 5 to 17 year age group (32.2% for 2018 compared to a five year average of 16.2%).
In 2018, fever and cough levels among New Zealand FluTrackers showed a peak at the beginning of August.
A burden of illness pyramid is a method for estimating the relationship between influenza-like illness at the community level with national influenza laboratory reports. The figure below describes surveillance levels from cough and fever through to positive laboratory test for influenza (self-reported) among FluTracking participants across New Zealand, for the four weeks of peak influenza activity beginning week ending 05/08/2017 to 26/08/2017.
Only a small proportion of those who reported fever and cough during the peak influenza activity tested positive for influenza.
Vaccination coverage was comparatively lower in the younger age groups.
Thank You, FluTrackers!
In total for Australia and New Zealand, over 1 million surveys were completed by FluTrackers throughout 2018. There were 51,616 Australian and New Zealand FluTrackers who completed at least one survey this year compared to 33,947 Australian FluTrackers in 2017 thanks to you inviting your friends, family and colleagues to join FluTracking. This is a 52% increase on the number of surveys completed last year, so thank you for your help!
We look forward to FluTracking again with you in 2019!
