This document discusses using social media data to track hay fever seasons and medication effectiveness in real-time. The author analyzed over 130,000 tweets mentioning "hayfever" or "hay fever" from June 2012 to April 2013. The geotagged tweets matched known pollen patterns in the UK. This suggests social media could provide a low-cost way for researchers and sufferers to identify local hay fever outbreaks and seasons. It may also provide insights into how effective medications are in relieving symptoms.

3. Hay fever or seasonal allergic rhinitis
is a common allergic condition
(Emberlin, 2010), defined as an
Immunoglobulin E (IgE) mediated
inflammatory response of the nasal
lining following exposure to an
allergen (Bousquet et al., 2008).

4. The current UK hay
fever prevalence is
between 20-25% of
the population,
projected to rise to
39% by 2030
(Emberlin, 2010).

5. Surges in incidence of allergic rhinitis in
spring and summer are commonly
known as the hay fever season, with
the main pollens in the UK being birch
pollen, March to mid May, and
grass pollen, late May to August
(Emberlin, 2010).

6. The Meteorological
Office (Met Office)
provide weekly pollen
forecasts and the
Royal College of
General
Practitioners (RCGP)
produce weekly
service reports.

7. For researchers and sufferers of hay
fever, there is currently no method
for identifying real-time,
geolocated hay fever incidence.

10. A promising approach in the related field
of Epidemiological Intelligence to detect
seasonal illnesses is the use of Social Media
(de Quincey & Kostkova, 2010). By collecting
incidences of users self reporting illnesses
on twitter, it has been shown that
outbreaks can be predicted 1-2 weeks
before RCGP data indicates (Szomszor et al, 2012).

18. Distribution similar to Pollen Calendars produced by the National Pollen
and Aerobiology Research Unit, with peaks in June/July, reductions
through August/September, no pollen from October to January and
then a rise in March

“meds”; “medication”; “pill’; “spray” and “drugs”).

23. Only 3,924
tweets (3%) had
a precise longitude and
latitude.
All tweets however
contained an
approximate
location
e.g. 16,365 were posted from
a profile that had a location
set as “London”.

25. “Thank you for sight of your map. It matches what I would
expect to see, broadly fewer instances of pollen being
registered in Scotland, more in the south and southeast of

England.” SummitPeter Burt, Biometeorologist

26. The higher
level of granularity that twitter enables for temporal analysis
means that daily peaks of hay fever incidence can be
identified in real time along with potentially pinpointing more
accurate start and end dates of the seasons within
different parts of the UK.
