Researchers and the American Academy of Ophthalmology (AAO) are warning that conjunctivitis, or pink eye, is a possibly sign of Covid-19.

A new Chinese study, published in Jama Ophthalmology, found that of 38 patients with Covid-19, 12 had ocular manifestations such as epiphora, conjunctival congestion or chemosis, and these commonly occurred in patients with more severe systemic manifestations.

“Understanding ocular manifestations of patients with Covid-19 may facilitate the diagnosis and prevention of transmission of the disease,” said researchers, led by Dr Ping Wu of the Yichang Central People’s Hospital, who added, “Although there is a low prevalence of SARS-CoV-2 in tears, it is possible to transmit via the eyes.

In an update to members, the AAO said patients who present with conjunctivitis, who also have fever and respiratory symptoms, including cough and shortness of breath, have travelled recently or have close contacts with Covid-19, could be infected with SARS-CoV-2.

“The Academy and federal officials recommend protection for the mouth, nose and eyes when caring for patients potentially infected with SARS-CoV-2.”
