CHARLOTTE — A county in North Carolina incorrectly told nearly 7,000 residents they had tested positive for the coronavirus due what officials say was a technical glitch. The messages were sent by text messages to more than 6,700 residents in Mecklenburg County on Friday, The Charlotte Observer reported. More than 500 people also received a county email with the notice. The county told residents that morning the messages were a “scam,” and that their health department does not notify people of their COVID-19 test results through text message. A corrected text or email was sent to those who received the incorrect messages, Diorio said in the email to commissioners.
