ANN ARBOR – Due to an exponential growth in COVID-19 cases in the area, the Washtenaw County Health Department announced Thursday that it is now experiencing delays in contact tracing calls and emails. “Don’t wait for a call from the Health Department," Jimena Loveluck, health officer for Washtenaw County Health Department, said in a statement. All other residents who receive a positive test should follow established guidance and will be contacted as capacity allows. A person is considered contagious 2 days before their symptoms start or before their positive test if they do not have symptoms. The next pop-up testing opportunities are scheduled for Sat, Nov 14 at the Ypsilanti District Library at 5577 Whittaker Road and Sat, Nov 21 at Washtenaw County Health Department at 555 Towner Street.

Toward the beginning of the pandemic, a study showed that the SARS-Cov-2 virus can survive on cardboard for as long as 24 hours and on stainless steel for about 72 hours. Figuring out how long a contagious virus can survive on human skin isn’t an easy challenge as not many people are willing to have live SARS-CoV-2 smeared on them just for science. That’s why Japanese researchers used an unusual alternative -- human skin collected at autopsy about 24 hours after death. What they found was significant -- the SARS-CoV-2 virus could survive on human skin for nine hours -- significantly longer than the roughly two hours that the flu virus could remain a threat.
