Yes, you can be incubating the virus and still have a negative COVID-19 test — and those negative results might be giving people a 'false sense of security.'
PhD, associate professor of Infectious Disease Epidemiology at Johns Hopkins Bloomberg School of Public Health, toldthat “swabbing for the virus is not a perfect process,” meaning your test might come back negative by mistake.Teen Vogue“It takes a few days for enough virus to replicate in you respiratory tract for [a test] to become positive,” Jones-Lopez said.
