The Wuhan coronavirus seems to have a low fatality rate, and most patients make full recoveries. Experts reveal why it's causing panic anyway.
- The outbreak of a novel coronavirus in Wuhan, China, has sparked fear and anxiety around the world, despite the virus' low fatality rate.
- People's psychological reactions to infectious diseases can sometimes be overblown and do more harm than good, some experts say.
- Still, preventative measures like increasing hand washing and avoiding touching your face will protect against coronavirus and other illnesses.

The outbreak of a new coronavirus has sparked fear and anxiety around the world.The pneumonia-like virus, which originated in Wuhan, China, has infected more than 8,100 people and killed 170.Advertisement
So far, the virus does not seem to be deadly as SARS, which killed 774 people from 2002 to 2003. SARS had a mortality rate of 9.6%, whereas only about 2% of people have died from the new coronavirus. But the number of people infected after one month has already surpassed the SARS outbreak's eight-month total.
Many patients of the new coronavirus have already made full recoveries. According to Chinese officials, most of those who've died were elderly or suffering other ailments that compromised their immune systems.
Experts say that for the most part, global panic over Wuhan coronavirus is unproductive and unwarranted: The public should take precautions to avoid getting sick, but the most effective preventative measures are everyday actions like increasing hand washing and avoiding touching your face.In addition, experts warn that fear will not stop the spread of the virus and can cause other negative social impacts. "There's the spread of infectious disease, then there's the spread of panic," Amira Roess, a professor of global health and epidemiology at George Mason University, told Business Insider. "They have very different mechanisms."Advertisement
In the early stages of an infectious disease outbreak, Roess added, much of the panic is "fear of the unknown."
The spread of disease and the spread of fear
Psychology research shows that novel, foreign threats raise anxiety levels more than familiar threats, and people tend to under-react to familiar threats.For example, there's about a one-in-seven chance that heart disease will be the cause of an American's death, whereas the chance they will die at the hands of a foreign-born terrorist is one in 45,808. But according to a 2016 Chapman University survey of American fears, "terrorist attack on nation" and "victim of terrorism" both ranked among the top five.Advertisement
This dynamic played out during the Ebola outbreak in West Africa from 2014-2016, according to Paul Slovic, a psychologist and president of the nonprofit Decision Research.
"What happened was quite consistent with what we know about risk perception," Slovic wrote in an article for the American Psychology Association. "The minute the Ebola threat was communicated, it hit all of the hot buttons: It can be fatal, it's invisible and hard to protect against, exposure is involuntary, and it's not clear that the authorities are in control of the situation."
Past outbreaks of Ebola, however, had much higher death rates than SARS and the new coronavirus: 25% to 90%. Worldwide, Ebola has killed more than 33,000 people since 1976.
Racist consequences of panic
Nationals of Asian descent in France, Canada, and the US are reporting incidents of racism due to public fears of the Wuhan coronavirus.The Guardian reported that nearly 9,000 parents near Toronto, Canada, have signed a petition to prevent students who had traveled to China in the last 17 days from attending school.Advertisement
"This has to stop. Stop eating wild animals and then infecting everyone around you," wrote one petition signer. "Stop the spread and quarantine yourselves or go back."The New York Times reported that businesses throughout Hong Kong, South Korea, and Vietnam have posted signs telling customers from mainland China they are not welcome. Asian students at Arizona State University, meanwhile - where a US case of coronavirus was confirmed - say they're facing jokes, stares, and isolation on campus.Advertisement
"I cough in class and everybody looks at me," a Vietnamese-American freshman at ASU told Business Insider's Bryan Pietsch.
Reasons for hope during this coronavirus outbreakExperts say a few factors should ease fears about the coronavirus: First, it was identified and determined to be a new virus more quickly than ever before. A week after it was discovered, Chinese authorities had already sequenced the virus and shared it with labs around the world.Advertisement
"Something that's remarkable here is that within a week, the RNA sequences of the virus are available on the internet, and many can look at it and begin to understand it," Richard Martinello, an associate professor of infectious disease at the Yale School of Medicine, told Business Insider. "That's something that's never been done before."
Second, a range of advancements in medical technology since coronaviruses were discovered in the 1960s have allowed clinical labs and virologists to conduct more in-depth research into the way these zoonotic viruses work.
For example, although scientists knew coronaviruses could infect humans because they're a cause of the common cold, the SARS outbreak marked the first time a coronavirus was traced back to animals. (It's possible, however, that coronaviruses from animals have made people sick in the past, Martinello said.)
In addition, Martinello pointed out that people in the US are far more likely to catch the seasonal flu than the Wuhan coronavirus. The preventative measures for both are the same, though: hand-washing, avoiding face-touching, and steering clear of contact with anyone who's sick.Martinello hopes that the widespread worry about the coronavirus will lead to lower rates of seasonal flu this year as people take better precautions.Advertisement
