"This is the whole point of current "self-quarantine" and "social distancing" measures, and the point of canceling large events in places with confirmed coronavirus cases. The expectation is not that the cancellation of large conferences and festivals will truly stop the virus' spread; individuals who are infected with the virus but don't know it will still likely go about their daily lives, sneezing and coughing and obligingly scattering the virus to new hosts. That is how viruses work. But by infecting fewer people, at a slower pace, the demand for medical services is itself slowed. This is also why public health experts have been so very alarmed at the Trump administration’s early-stages bungling, and especially at the continued unavailability or rationing of testing kits for the new coronavirus strain. When the disease reached epidemic levels in Wuhan, China, the government closed borders and instituted aggressive containment measures intended to block the epidemic from reaching farther, faster; that time was necessary to give China and all other countries more time to prepare for the virus' likely expansion. That was the point at which the United States was supposed to be ramping up testing (but the early tests were botched), breaking out the emergency plans for a pandemic (but Trump dissolved the national security team tasked with coordinating such plans), and making sure state and local governments were up to speed on what was going on. Instead, U.S. officials hesitated to make preparations for fear it would give Donald Trump the Angries. Trump himself contradicted officials who did make public statements, allegedly getting angry because he did not want the stock markets to go down in response. The net result is that the nation squandered weeks of preparedness time and we still, even today, have very little information about how the virus is spreading. That makes what happens next much more difficult."
