Asymptomatic COVID-19 Patients Are Just As Contagious As Patients With Symptoms

People with confirmed COVID-19 who are not showing any symptoms of the disease are as contagious as those with symptoms.According to.a new study, asymptomatic COVID-19 patients can test positive for the virus for up to 18 days after diagnosis.In samples collected from patients, the virus declined more slowly in those without symptoms than in those with symptoms.Many asymptomatic patients also had evidence of "viral shedding", meaning they were contagious for at least 30 days after diagnosis.
