Researchers unlock key to real-time hay fever tracking
Researchers from Keele University have found that Twitter could provide a more accurate way of tracking hay fever in the UK than current Met Office pollen counts and NHS data, paving the way for sufferers to be able to access free real-time hay fever information based on their precise location.
After realising that there is currently no method for identifying real-time location-based hay fever occurrence, the researchers collected and analysed over 500,000 UK-located tweets that mentioned hay fever over two years. These tweets were cross-referenced with NHS data to prove that spikes in mentions of hay fever closely correlate with the days that patients report to GPs with hay fever symptoms. The researchers have suggested that this could provide a higher level of detail for sufferers, as Twitter can contain geolocation data, is in real-time and consists of actual reports of hay fever, rather than just pollen counts.
Dr Ed de Quincey from Keele University, who led the research team, comments:
"We've found that tracking Twitter users' mentions of their hay fever symptoms, rather than any specially created hashtags, can give us an accurate representation of which locations are reporting high levels of hay fever incidence, and when they're experiencing them."
The next stage of the research will be to delve deeper into the content of tweets about hay fever, with further qualitative analysis planned to help accurately identify which locations see a higher incidence of hay fever.
Ed de Quincey continues: "The data could be used to create a real-time hay fever hotspot map. This could give more specific information for sufferers than the current Met Office pollen count system, which only collects data from and forecasts for a limited number of points across the country. Ideally, this could then be combined with the Met Office's daily pollen count and other sources of hay fever information on the internet to provide sufferers with a comprehensive, one-stop update about current hay fever conditions."
