Therefore, eyes are also one of the transmission routes of novel coronavirus.Currently, there is no specific study on the residue time of novel coronavirus in eyes. However, according to common viral conjunctivitis, after the systemic symptoms improve, the virus content in eyes will gradually decrease, which basically takes 2 to 3 weeks.
