The county has set up an online system, asking residents to fill out a form if they have tested positive for COVID-19: Go to www.AlbanyCounty.com and follow the red COVID-19 information bar at the top of the page to report positive results. So far, county spokeswoman Mary Rozak said on Monday morning, 800 positive tests had been reported through the portal, which was set up last Thursday. “It continues to grow,” she said.
