HASLEMERE residents took part in the #BBCPandemic experiment last year and the "astonishing" results will be revealed tonight.

Switch on at 9pm this evening to watch BBC Four programme Contagion! to find out how many Haslemere residents were "infected" and what happened when the experiment went nationwide.

The town was selected as an ideal small close-knit community to predict how swiftly an outbreak of a deadly contagious virus could spread nationwide, after “Patient Zero”, TV presenter and mathematician Dr Hannah Fry, walked its streets.

Hannah and emergency medic Dr Javid Abdelmoneim will be fronting the ground-breaking citizen scientific experiment when it is screened at 9pm. It has been billed as a “shocking revelation”.

To take part in the “Haslemere Outbreak” study, residents downloaded an app on their smartphones that went live at 12am on October 12 for a 72-hour period.

The app did not identify participants, but tracked and stored their location movements to find out if they had been infected by Hannah or “carriers” she had come into contact with.

App users (pictured) turned out in force at Haslemere Museum at the conclusion of the study on October 15 for a filmed event that concluded the study, but they were sworn to secrecy on how infectious the town had turned out to be.

"A huge thank you to everyone in Haslemere who took part and helped make the experiment such a success,” the BBC Pandemic team said. “We hope you enjoy spotting yourselves in the programme."
