Here's the latest on Aug. 19, 2020.

With the unofficial start to fall three weeks away, scientists and medical researchers are trying to anticipate how the change of the season will affect the coronavirus crisis.

Fall means a return to school. While most D.C.-area K-12 schools will begin virtually, some colleges are opening up despite trouble at some campuses that have opened up nationwide, Bowie State University welcomed back 800 students to campus on Monday and Catholic University on Tuesday had freshmen and transfer students move in.

Weather could also affect the pandemic's course. Scientists are looking to South Africa and Australia, where it's currently winter, to forecast what to expect in the northern hemisphere. One early study suggests that lower humidity found in winter could lead to more spread, David A. Andelman, executive director of The RedLines Project, wrote for NBC THINK.

If winter weather does promote the spread of coronavirus, social distancing would become even more key to containing outbreaks.

Researchers at the University of Virginia Biocomplexity Institute looked at three scenarios for the commonwealth. In the best-case scenario for Virginia, about 2,000 daily confirmed cases by October are expected. In the worst case, closer to 3,000 people are expected to be diagnosed every day.

The Centers for Disease Control last week released a reported synthesizing the projections from 13 models that each had different assumptions about social distancing. By Sept. 1, the models together project how many new cases per 100,000 residents each area can expect in a week.

For every 100,000 residents, D.C. may approach 500 new cases, Maryland about 5,000 and Virginia under 10,000 new cases.


What the Data Shows

The seven-day average of new cases added daily is down compared to last week, falling from 72 to 61 in D.C.; 713 to 627 in Maryland and 998 to 871 in Virginia. They've all declined over the past day, as well.

On Tuesday, D.C. added 52 cases, Maryland diagnosed 520 and Virginia counted 793.

Since a mid-July surge in cases, Virginia has seen cases plateau or begin to recede in most areas. But the surge is still "significant," especially in the far southwestern parts of the state, according to a report from researchers at the University of Virginia Biocomplexity Institute.

Northern Virginia also has seen an increase in the number of hospital beds needed, but isn't expected to exceed capacity before Nov. 1, the report said. 
There are bright spots in the data assessing where the region stands in fighting the pandemic.

Maryland's rate of positive tests is continually sliding, hitting a new low point of 3.21% over the week. Prince George's is the only county to have a rate over 5%. People under 35 are also getting a smaller proportion of positive tests. 
D.C. has also maintained a positivity rate under 4%.

How to Stay Safe

There are ways to lower your risk of catching coronavirus. Here are guidelines from the CDC:

  • Anyone over the age of 2 should wear a mask or face covering. Keep it over your nose and mouth.
  • Wash your hands often. When you do, scrub with soap and water for at least 20 seconds. As a backup, use hand sanitizer with at least 60% alcohol.
  • Avoid close contact with anyone who lives outside your home. That means staying six feet away from anyone outside your circle, even if you're wearing masks.
  • Always cover coughs and sneezes.
  • Clean and disinfect frequently touched surfaces.
