University of Waterloo researchers using social media to predict disease outbreaks – Globalnews.ca
Researchers at the University of Waterloo are using social media in an attempt to forecast when we may see future outbreaks of diseases like COVID-19 and measles.
Using simulations, researchers at the school developed a method that uses social media interactions to predict when an outbreak appears likely.
It considers how a series of small incidents, like people espousing anti-vaccine views, would grow to cause a larger, more important change, such as an outbreak of measles.
“It’s looking for signals that indicate a bout of vaccine hesitancy or vaccine refusal might be coming, based on characteristics of how people interact on Twitter,” Waterloo professor Chris Bauch told Global News through email.
He said their “hypothesis is that a bout of vaccine refusal would then lead to an outbreak.”

Bauch, who is the study’s lead researcher, says the method could be used by decision-makers to determine where we are most likely to have an outbreak.
“Once they’ve identified populations that are exhibiting these signals, they can try to build trust and boost vaccine coverage in vaccine-hesitant members of those populations,” he said in a statement.
His team used a simulated social media network to discover early warning signs of disease outbreak, including dissimilar joint counts and mutual information.
“A dissimilar joint count is the number of instances of communication between, for example, pro-vaxxers and anti-vaxxers, which we found tends to increase prior to an outbreak,” said Brendon Phillips, co-author of the study. “Mutual information measures the relationship between someone’s opinion and whether they’re sick or not.
“We used computer simulations to examine how likely it is that someone who is an anti-vaxxer was infected in the past or that they’re susceptible to infection now.”
Bauch says they use sentiment information from tweets to determine someone’s stance on vaccination.
The researchers found that at this stage in its development, the method can show that a disease outbreak is likely but not exactly when it will come as that depends partly on chance events.

Italian FM says Israel gave US ‘last minute’ warning about drone attack on Iran
CAPRI, Italy (AP) — The United States told the Group of Seven foreign ministers that it received “last minute” information from Israel about a drone action in Iran early this morning, Italy’s foreign minister says.
Italian Foreign Minister Antonio Tajani, who chaired the meeting of ministers of industrialized countries, says the United States provided the information at session this morning that was changed at the last minute to address the suspected attack.
Tajani says the US informed the G7 ministers that it had been “informed at the last minute” by Israel about the drones. “But there was no sharing of the attack by the US. It was a mere information.”
Early Friday, Iran fired air defenses at a major air base and a nuclear site near the central city of Isfahan after spotting drones, part of an apparent Israeli attack in retaliation for Tehran’s unprecedented drone-and-missile assault on the country last weekend.
In a communique following the three-day meeting, the ministers urged the parties “to prevent further escalation.”
