Old infections, new variants complicate Virginia Tech s picture of COVID-19

Virginia Tech’s COVID-19 numbers suggest a daunting situation. More students are living in campus quarantine than ever before. The university on Tuesday reported more people testing positive in a single day — 61 individuals — than at any point since early September. President Tim Sands says the community should assume different strains of COVID-19, thought to be more contagious, are circulating locally. But two opposing factors — old infections and new variants — are complicating this picture. Is a surge in cases merely a result of sensitive COVID-19 tests that can pick up virus from a person no longer infectious? Or a prelude to a more contagious COVID-19 variant that could become the dominant strain by late March?

Johnson and Johnson vaccine could be key to the distribution slowdown
