Novel coronavirus pneumonia is a respiratory transmitted virus that can also be transmitted through the eyes. If you touch the respiratory secretions of an infected person on your hands and then rub your eyes, you may rub the virus into your eyes. The eyes normally have fluid circulation exchange, and if the virus enters the eyes, it may enter the body directly through the circulation leading to infection, so attention to hand hygiene is advocated. Some individual experts also believe that if it is in a medical environment, such as when a patient is doing tracheal intubation or bronchoscopy, their respiratory secretions are very large and may form aerosols, which may also infect through the eyes. Therefore, in medical operations, it is advocated that health care workers should wear goggles or even a full-scale protective hood if airway secretions are particularly high to avoid infection through the eyes. So for the general public, it is important to know that the eyes may be the route of infection and to pay attention to hand hygiene. In addition to wearing a good mask, you should not rub your eyes until you have washed your hands after pressing the button in the elevator when taking public transportation. However, the main route of infection is through the respiratory tract, because the receptor of the virus is angiotensin-converting enzyme II, mainly in the alveolar cells, and the risk of infection through the eyes is still very low, but it does have this possibility.
