The adage, “an ounce of prevention is worth a pound of cure” is certainly true for COVID-19. The disease has no cure, and right now, the only way to avoid completely overwhelming our medical system is to prevent the virus’s spread by isolating ourselves from each other.
Governor Tom Wolf has ordered residents of Allegheny County and dozens of other Pennsylvania counties to "stay at home" through April 30, though the order could be extended. As a result, parents are canceling their kids’ birthday parties, and people are worried about losing their jobs, while others can’t visit nursing homes to see their loved ones.
It does seem that Allegheny County’s rate of growth of confirmed cases is starting to slow, but there is still wide variability from day to day, which makes it difficult to draw any firm conclusions. On Wednesday, the total number of cases grew by about 9.5%, the second lowest growth rate so far. But there still isn’t enough data to show a general downward trend, and state and county officials aren't ready to say that the curve is flattening.
“We are seeing some positive indicators, but it’s a little too soon to say, ” said Dr. Sharon Watkins, an epidemiologist with the state Health Department, during a press conference on Monday.
Social distancing is hard, in part, because there’s no telling how long this period of isolation will last. One Pittsburgher who’s really feeling this is Bloomfield neighborhood resident Sarah Lewis, whose relationship ended three weeks ago.
“He broke up with me,” said Lewis, talking by phone from her studio apartment.
The break-up occurred just before Allegheny County and the city of Pittsburgh started restricting people’s freedom of movement so as to stop coronavirus from ripping through region.
“Spending the better part of six months sharing a bed with another human, and having this person that you could cuddle with and touch, to literally not even being able to be in the same room as my best friends has been very hard,” she said.
Lewis said she’s strict about social distancing because she does not want to infect someone who might end up dying from COVID-19. She still has to go to her job at a credit union, but she stays six feet away from coworkers, and only goes to the grocery store when she needs to.

“If nobody ever went out and nobody ever touched anybody else, this disease could not pass at all,” said Dr. Mark Roberts, the director of the University of Pittsburgh’s Public Health Dynamics Laboratory, which is trying to predict how COVID-19 will spread in western Pennsylvania.
“Even with schools closed, if people went about their lives as normal, there would be tens of thousands of cases requiring hospitalization in western Pennsylvania alone,” he said.
There is evidence that suggests many Western Pennsylvanians are doing their part to stop coronavirus in its tracks.
A decline in ridership has led the Port Authority to cut services by 25 percent. Cell phone data compiled by data science company Unacast show that residents of Allegheny County and surrounding areas are traveling less.
Some of this is because most public places have been closed for weeks. Though essential businesses, like grocery stores, remain open.
Kostas Pelechrinis, a social computing researcher at Pitt, began tracking activity at three Pittsburgh groceries using data he scraped from Google on March 13.
“The first couple of weeks that I was collecting data, I didn’t see that much of decline,” said Pelechrinis. “[Just a] four, five percent reduction.”
Since that time, Pelechrines has increased his monitoring efforts to include thirty Pittsburgh groceries, and he said activity continues to decline.
“In the last couple of days, three of four days, it’s about 20 percent down,” he said.
Pelechrinis said his data suggest Pittsburghers are taking social distancing seriously. But not everyone is doing a great job. For example, Pittsburgh decided to close certain outdoor areas, like the Mount Washington overlooks, to discourage crowds.
While it's hard to say how long social distancing will last, we do know from Wuhan that it works.
At the height of Wuhan’s epidemic, hospitals were overrun with COVID patients, and more than 3,000 people have died in Hubei province, where the city is located. Now, the city of 11 million people will go days at a time without a single new case.
