In the case of infection with SARS‐CoV or MERS‐CoV, reports and reviews have not identified conjunctivitis as a sign or symptom, even in cases diagnosed early in their disease.65, 66, 67, 68 For disease caused by NL63, in a review of 15 studies which had a combined number of cases of over 7,500, 69  only a single study from France reported the appearance of conjunctivitis, and then conjunctivitis was seen in 17 per cent of the 300 cases. 70  NL63 was initially isolated from a child with both bronchiolitis and conjunctivitis, but the other seven cases in that first report did not have conjunctivitis as a noted sign or symptom. 71  Infections with HKU1 have not produced any associated conjunctivitis,72, 73 and while there is a report showing that a patient with Kawasaki disease infected with OC43/HKU1 had conjunctival injection, 74  this conjunctivitis was most likely due to the underlying Kawasaki disease.
