Dangerous Curves

If this is the new normal, where incomplete data and media-fueled panic rule the day, that is an even more frightening prospect than what’s happening right now.

If you weren’t very ill in late January or February, you probably know someone who was. The complaints often sounded the same: A fever for days, a stubborn and unusual-sounding cough, a persistent sore throat—the severity of the symptoms seemed worse than the usual influenza.
Doctors, assuming it was a version of the seasonal flu, administered flu-fighting drugs without testing. (My college daughter was very sick with the same symptoms; her flu test was negative.) Plenty of afflicted Americans just stayed in bed without ever seeing a physician.
Obviously, anecdotal evidence that the COVID-19 illness has been around for at least the past few months isn’t enough to make the case that there’s a chance the worst days of the outbreak are behind, not ahead, of us. But data from the Centers for Disease Control seems to support the possibility that the country has been besieged by the novel coronavirus since the start of 2020.
And while political leaders and medical experts push for more and more draconian measures to “flatten the curve,” it raises some questions. Are we looking at the right “curve?” And how accurate is the current curve if it doesn’t include possible cases before the height of the hysteria began in late February and early March?
The curve, according to one report, “refers to the projected number of people who will contract COVID-19 over a period of time.” To date, the novel coronavirus curve undoubtedly looks ominous. Only a smattering of coronavirus cases was reported in the U.S. during January and February; that figure jumped at the beginning of March due to testing availability.
The first known American victim, a Washington resident who had traveled back from Wuhan, the epicenter of the outbreak, was confirmed on January 21. The U.S. coronavirus graph basically flatlines from that date until the last few days of February.
But since the disease originated in China in December at the latest, it’s highly unlikely the number of reported cases in the United States between January 1 and late February is accurate. (It’s important to note that in its order prohibiting most noncitizens from entering the United States from China, the White House confirmed that an average of 14,000 people per day traveled between the two countries in 2019. That means tens of thousands of potentially infected people entered the country for weeks prior to the travel stop.)
Therefore, how could a highly-contagious virus remain nonexistent in a free-moving society for several weeks?
The answer is, it probably did not. The CDC tracks a category called “influenza-like illness,” or ILI. Since symptoms of the flu and coronavirus are very similar, it’s instructive to look at this data, which is based on visits to health care providers in all 50 states, Washington D.C. and Puerto Rico. “For this system, ILI is defined as fever (temperature of 100°F or greater) and a cough and/or a sore throat,” reads the CDC webpage on influenza-like illness.
“What influenza-like illness is saying to us is that you have a virus likely affecting your respiratory system that is making you feel crummy and, currently aside from influenza, there aren’t good therapies for these other viruses, so we just treat the symptoms,” Dr. Michael Ison, a professor of infectious diseases at Northwestern University in Chicago, told WebMD.com in January. The underlying cause could be any number of undetected respiratory viruses.
