Is it true that looking at each other can convey “pink eye”?


Recently, the number of patients suffering from “pink eye” has gradually increased, and it is often the case that the entire family is infected. Recently, the topic “A woman’s pinkeye infects the whole family, even the dog’s eyes turn red” has been on the hot search list. There has been a popular saying among the people that “pinkeye” can be contagious just by looking at it… Is this true?

  Viral cold patients are susceptible to infection

What we commonly call “pink eye” generally refers to acute conjunctivitis, which mainly includes epidemic keratoconjunctivitis, pharyngeal conjunctival fever and acute hemorrhagic conjunctivitis. This type of acute conjunctivitis can be caused by adenovirus, enterovirus, herpes simplex virus, etc. Caused by viruses. Therefore, especially when the seasons change and respiratory infectious diseases are high, patients who have had viral colds are more likely to “infect themselves” with “pink eye” and then infect their family members.

“Pink eye” can cause different eye symptoms including red eyes, foreign body sensation, increased secretions, burning sensation, tearing, etc. If not treated in time, the inflammation will be severe and may have a direct impact on vision.

  It’s outrageous to get a “red eye” at just one glance

“Pink eye” is an epidemic infectious eye disease worldwide in the past 40 years. It is highly contagious and the population is generally susceptible. It is mainly spread through contact and can be spread through swimming pool water, public bathing, use of public goods, etc. It is more likely to cause epidemics in entertainment venues, schools, hospitals and other collective places. Family members who are in close contact with patients are also easily infected.

However, “pink eye” does not spread through the air or respiratory tract, so it is an exaggerated rumor that someone with “pink eye” can be infected just by looking at it. Ophthalmologists often see a large number of patients with “pink eye” in their daily work, but the chance of being infected is very low.

If you do these things well, the people you live with will be able to survive.

As a healthy person, if you are around someone with “pink eye”, try to stay isolated from them and avoid contact, especially objects that have come into contact with the patient’s eyes. For example, towels used by family members and patients should be placed separately and not together; washbasins cannot be shared and it is recommended to wash your face with running water; do not lie on the bed where the patient has been lying, especially do not touch pillows and sheets used by the patient. Bedding, as secretions and tears from the patient’s eyes may remain on them. If you touch the above items, wash your hands as soon as possible with hand sanitizer or 75% alcohol or other disinfectants.

Try not to touch your eyes with dirty hands. If you want to touch your eyes, you must disinfect your hands or use a sterile cotton swab to touch your eyes before touching them. If you accidentally come into contact with an object that has been in contact with a patient, or if you have been to a public swimming pool or bathhouse and find a patient with “pink eye” among them, you can observe first or take preventive medication under the guidance of a doctor.

In short, infection can be avoided by maintaining isolation, washing hands frequently, opening windows at home for proper ventilation, living a regular schedule, relaxing your mind, and actively exercising. Text/Song Dan (Beijing Tsinghua Chang Gung Memorial Hospital)
