On December 30, researchers utilizing synthetic intelligence methods to comb by way of media and social platforms detected the unfold of an uncommon flu-like sickness in Wuhan, China.
It could be days earlier than the World Well being Organisation launched a danger evaluation and a full month earlier than the UN company declared a world public well being emergency for the novel coronavirus.
May the AI methods have accelerated the method and restricted, and even arrested, the extent of the COVID-19 pandemic?
Clark Freifeld, a Northeastern College laptop scientist working with the worldwide illness surveillance platform HealthMap, one of many methods detecting the outbreak, mentioned it stays an open query.
“We identified the early signals, but the reality is it’s hard to tell when you have an unidentified respiratory illness if it’s a really serious situation,” mentioned Freifeld.
Dataminr, a real-time danger detection expertise agency, mentioned it delivered the earliest warning about COVID-19 on December 30 based mostly on eyewitness accounts from inside Wuhan hospitals, footage of the disinfection of the Wuhan seafood market the place the virus originated and a warning by a Chinese language physician who later died from the virus himself.
“One of our biggest challenges is we tend to be reactive in these situations, it’s human nature,” mentioned Kamran Khan, founder and chief government of the Toronto-based illness monitoring agency BlueDot, one of many early methods that flashed warning flags in December over the epidemic.
“Whenever you’re dealing with a new, emerging disease, you don’t have all the answers. Time is your most valuable resource; you cannot get it back.”
Khan, who can also be a professor of drugs and public well being on the College of Toronto, informed AFP by phone the info confirmed “echoes of the SARS outbreak 17 years earlier, but we didn’t know was how contagious this was.”
However, AI methods have confirmed to be priceless in monitoring epidemics by scouring a various array of sources starting from airline bookings, Twitter and Weibo messages to information experiences and sensors on linked units.

– People within the loop –
Nonetheless, Freifeld mentioned AI methods have limits, and the massive selections should nonetheless be made by people.
“We use the AI system as a force multiplier, but we are committed to the concept of having humans in the loop,” he mentioned.
AI and machine studying methods are possible to assist the battle in a number of methods, from monitoring the outbreak itself to dashing up drug testing.
“We can run simulations unlike we’ve ever done before, we understand biological pathways unlike we’ve ever understood before, and that’s all because of the power of AI,” mentioned Michael Greeley of the fairness agency Flare Capital Companions, which has invested in a number of AI medical startups.
However Greeley mentioned it stays difficult to use these applied sciences to sectors like drug supply the place the traditional testing time could be years.
“There is extraordinary pressure on the industry to start using these tools even though they may not be ready for prime time,” he mentioned.
Based on Khan, AI helps within the containment section with methods that used “anonymized” smartphone location information to trace the development of the illness and discover hotspots, and to find out if individuals are following “social distancing” tips.
Andrew Kress, CEO of the well being expertise agency HealthVerity, mentioned it stays difficult to gather medical information for illness outbreaks whereas complying with affected person privateness.
It’s potential to detect tendencies with indicators resembling pharmacy visits and gross sales of sure medicines and even on-line searches, Kress mentioned, however aggregating that has privateness implications.
“We need to have a real discussion about balance and utility around specific use cases and potentially the right kind of research to continue to figure out new ways to leverage some of these nontraditional data sources,” Kress mentioned.
– Information mining –
AI methods are additionally being put to work to scour the 1000’s of analysis research for clues on what remedies is perhaps efficient.
Final week, researchers joined the White Home in an effort to make accessible some 29,000 coronavirus analysis articles that may be scanned for information mining.

The hassle introduced collectively the Allen Institute for AI, Chan Zuckerberg Initiative, Microsoft, Georgetown College and others.
Via Kaggle, a machine studying and information science group owned by Google, these instruments shall be brazenly accessible for researchers around the globe.
“It’s difficult for people to manually go through more than 20,000 articles and synthesize their findings,” mentioned Kaggle CEO and co-founder Anthony Goldbloom.
“Recent advances in technology can be helpful here. We’re putting machine-readable versions of these articles in front of our community of more than four million data scientists. Our hope is that AI can be used to help find answers to a key set of questions about COVID-19.”
