An Italian-based artificial intelligence company is regularly analyzing social media posts about the coronavirus for their emotional content.

Why it matters: Classifying tens of thousands of posts by their emotional tone provides a snapshot of how people feel about the pandemic. Spoiler alert: not great!

How it works: Expert System specializes in semantics and natural language reading, a branch of AI involving computer systems that attempt to make sense of written language.

  • In doing so, a computer can rapidly analyze vast amounts of the written word — like, for example, a day's worth of social media posts about the COVID-19 pandemic.

For the past few weeks, Expert System has been collecting English language social media posts each day that feature frequently used hashtags like #coronalockdown and #covid19. Its AI can extract the emotional content of those posts, which is then analyzed and interpreted by Sociometrica.

  • On April 24, "fear" had become the single most widespread emotion, displacing "sadness."

But, but, but: Such negative feelings have been declining over the past 10 days, from 62.4% to 45.5%. At the same time, neutral and positive feelings are on the rise, with particular growth around posts showing "hope."

  • Also increasing in intensity is "health fanaticism," which Expert System defines as "a feeling of fear and anxiety around certain aspects of health and an emphasis on defending the health of one’s own body."

The bottom line: A natural language AI can tell you what you probably already know: the pandemic is terrible, but if you squint hard enough, there's light at the end of the tunnel.

The pandemic hasn't hampered the health care industry

The economy has been tanking. Coronavirus infections and deaths have been rising. And the health care industry is as rich as ever.

The big picture: Second-quarter results are still pouring in, but so far, a vast majority of health care companies are reporting profits that many people assumed would not have been possible as the pandemic raged on.

13 states set new highs last week for coronavirus infections recorded in a single day, according to the COVID Tracking Project (CTP) and state health departments. Kansas, Montana, North Dakota and Wyoming surpassed records from the previous week.

The big picture: The pandemic is getting worse again across the country, and daily coronavirus cases have risen in the U.S. for six straight weeks, according to a seven-day average tracked by Axios. The U.S. reported over 80,000 new cases on both Friday and Saturday.

New Zealand now has active no coronavirus cases in the community after the final six people linked to the Auckland cluster recovered, the country's Health Ministry confirmed in an email Wednesday.

The big picture: The country's second outbreak won't officially be declared closed until there have been "no new cases for two incubation periods," the ministry said. Auckland will join the rest of NZ in enjoying no domestic restrictions from late Wednesday, Prime Minister Jacinda Ardern said, declaring that NZ had "beat the virus again."
