Could AI Help Prevent Future Epidemics?

A new study suggests that ChatGPT could be used to prevent future epidemics. For the study, researchers developed a model that simulates the spread of an illness similar to Covid-19.

According to the Daily Beast newspaper, the fake model developed by a team of researchers at Virginia Tech, was a Covid-like deadly airborne pathogen called the “Catasat virus”, causing symptoms that range from a light cough at best, to a fever and moderate cough at worst.

For their model, the researchers created 100 different personas with names, ages, personality traits, all living in the fictional town of Dewberry Hollow.

ChatGPT predicted the behaviors of those personas after the outbreak of the virus in three different experiments. In the first, the personas were given no additional health-related information like how much the virus is spreading in the town and how Catasat was affecting them. In the second, the personas were given information about their own health—allowing them the ability to self-quarantine if it chose to do so. In the third, the personas were given information about their own health and the town’s growing number of cases.

The first experiment resulted in the epidemic spreading until nearly every citizen of Dewberry Hollow was infected. However, once the personas were informed of their own health situation in the second experiment, there was a sharp decline in generative agents leaving their house and number of overall Catasat cases.

Armed with the full gamut of information and context about the virus, though, the generative agents in the third experiment were able to reduce the number of cases and bend the curve much more quickly than the previous experiments.

“We coupled an epidemic model with ChatGPT, in a unique and innovative way to predict human behaviors during epidemics,” said Ross Williams, a doctoral student in industrial and systems engineering at Virginia Tech.

“We think generative AI has the potential to provide us with synthetic data on human behavior so policy makers can make more informed choices,” Williams added.

According to the team, their findings indicate that AI could significantly help prevent future epidemics by providing a fairly accurate picture of how we’d respond to a potential disease outbreak.

Alphabet's Google has advised some employees on US visas to avoid international travel due to delays at embassies, Business Insider reported on Friday, citing an internal email.

The email, sent by the company's outside counsel BAL Immigration Law on Thursday, warned staff who need a visa ⁠stamp to re-enter the United States not to leave the country because visa processing times have lengthened, the report said.

Google did not immediately respond to a Reuters request for comment.

Some US embassies and consulates face visa ⁠appointment delays of up to 12 months, the memo said, warning that international travel will "risk an extended stay outside the US", according to the report.

The administration of President Donald Trump this month announced increased vetting of applicants for H-1B visas for highly skilled workers, including screening social media accounts.

The H-1B visa program, widely used by the US ⁠technology sector to hire skilled workers from India and China, has been under the spotlight after the Trump administration imposed a $100,000 fee for new applications this year.

In September, Google's parent company Alphabet had strongly advised its employees to avoid international travel and urged H-1B visa holders to remain in the US, according to an email seen by Reuters.

Global data-center dealmaking surged to a record high through November this year, driven by an insatiable demand for ​computing infrastructure to meet the boom in artificial intelligence usage.

Data from S&P Global Market Intelligence showed that there were more than 100 data center transactions during the period, with the total value sitting just under $61 billion.

WHY ‌IT'S IMPORTANT

Interest ‌in data centers ‌has ⁠swelled ​this ‌year as tech giants and AI hyperscalers have planned billions of dollars in spending to scale up infrastructure.

AI-related companies have powered much of the gains in US stocks this year, but concerns over lofty ⁠valuations and debt-fueled spending have also sparked worries ‌over how quickly corporates can ‍turn the investments ‍into profits.

BY THE NUMBERS

Including M&As, asset ‍sales and equity investments, data center investments hit nearly $61 billion through the end of November, already surpassing 2024's record high $60.81 billion.

Since ​2019, data center dealmaking in the US and Canada totaled about $160 billion, ⁠with Asia-Pacific reaching nearly $40 billion and Europe $24.2 billion.

"High interest comes from financial sponsors, which are attracted by the risk/reward profile of such assets. Private equity firms are eager buyers but are generally reluctant sellers, creating an environment where availability for sale of high-quality data center assets is scarce," said Iuri ‌Struta, TMT analyst at S&P Global Market Intelligence.

Google's YouTube was ​down for thousands of users in the ‌United ‌States ‌on ⁠Friday, ​according to ‌Downdetector.com, Reuters reported.

There were more than 10,800 reports of ⁠issues with ‌the streaming ‍platform ‍as of ‍08:15 a.m. ET, according to Downdetector, ​which tracks outages by ⁠collating status reports from a number of sources.

.
Outage ‌reports exceeded 1,300 ‍in ‍Canada as of ‍8:29 a.m. ET; and more than 3,000 in the UK of ​8:30 a.m. ET.

YouTube did not immediately ⁠respond to a Reuters request for comment.

The actual number of affected users may differ from what's shown on Downdetector because these reports are user-submitted.
