Conjunctivitis: causes, symptoms, and prevention

Conjunctivitis is the inflammation of the conjunctiva, the mucous membrane that lines the inside of the eyelids and covers the white part of the eye. It is a common reason for ophthalmological consultations in both children and adults.

According to specialists at Quirónsalud, the condition can be categorized into several types:

- Viral conjunctivitis: Caused by viruses similar to those responsible for respiratory colds. It is highly contagious and can spread through coughing, sneezing, or contact. - Bacterial conjunctivitis: Characterized by sticky yellowish or greenish-yellow discharge. It is contagious, typically spread through direct contact with infected hands or objects. - Allergic conjunctivitis: A non-contagious form triggered by ocular allergens such as pollen or dust, which can be seasonal or occur year-round. - Other causes: Irritation can also be caused by certain medications or various chemical substances.
