The COVID-19 outbreak that has infected more than half a million Americans is killing people or causing them to become seriously ill at vastly different rates in different states, baffling scientists who are still learning about the coronavirus that causes the illness.
The virus so far has killed at least 23,529 people in the United States, a case fatality rate of just over 4 percent.
But the true mortality rate of COVID-19 is almost certainly much lower. Studies have showed that many infected with the virus show no symptoms, or nothing worse than a common cold, suggesting that the actual number of people who have contracted the virus is much larger than the 579,390 who had tested positive as of Tuesday morning.
The worst outcomes have come in states with the highest number of cases. Experts said that is likely a function of state rules that govern who is eligible to get one of the limited number of tests available: Only those who are sickest, and thus most likely to die from the disease, are tested, while those who are likely to make a speedy recovery are sent home to convalesce.
