For a spiky sphere just 120 nanometers wide, the coronavirus can be a remarkably cosmopolitan traveler.
Spewed from the nose or mouth, it can rocket across a room and splatter onto surfaces; it can waft into poorly ventilated spaces and linger in the air for hours. At its most intrepid, the virus can spread from a single individual to dozens of others, perhaps even a hundred or more at once, proliferating through packed crowds in what is called a superspreading event.

WASHINGTON (AP) — Ohio Gov. Mike DeWine’s positive-then-negative test results for the coronavirus are a reminder that no test is definitive.
The governor tested positive using a rapid test Thursday, before testing negative later in the day using a more sensitive laboratory-developed test. He was tested because he was going to meet with President Donald Trump during his visit to the state.

For months, the call for coronavirus testing has been led by one resounding refrain: To keep outbreaks under control, doctors and researchers need to deploy the most accurate tests available — ones reliable enough to root out as many infections as possible, even in the absence of symptoms.
That’s long been the dogma of infectious disease diagnostics, experts say, since it helps ensure that cases won’t be missed. During this pandemic, that has meant relying heavily on PCR testing, an extremely accurate but time- and labor-intensive method that requires samples to be processed at laboratories.
