Yes, conjunctivitis is very contagious. It is caused by a virus, bacteria, or an allergy, and can be spread through direct contact, or through the air from an infected person. It is important to take precautions to prevent the spread of conjunctivitis, such as washing your hands often, avoiding touching your eyes, and not sharing towels, makeup, or clothing.
Symptoms of conjunctivitis include redness and swelling of the eye, a gritty sensation, and itching or burning. The eye may also produce a thick, yellow discharge. Those who are infected should seek medical attention to determine the cause and the best course of treatment. Antibiotic eye drops or ointments may be prescribed for bacterial conjunctivitis, while antiviral medications may be prescribed for viral conjunctivitis. Eye drops may be used to reduce the irritation and redness associated with allergic conjunctivitis.
It is important to practice good hygiene to avoid spreading conjunctivitis to others. Avoid touching your eyes and wash your hands often. Disinfect any surfaces that may have come into contact with the infected person, such as door handles, keyboards, and phones. Do not share towels, makeup, or other personal items with those who are infected. Lastly, be sure to throw away any tissues or wipes that have been used by the infected person.
