Is true conjunctivitis considered highly contagious?

True conjunctivitis, particularly when caused by viral or bacterial infections, is indeed considered highly contagious. The nature of these types of conjunctivitis allows for rapid transmission from one individual to another, primarily through direct contact with infected eye secretions or contaminated surfaces. This is why it's crucial for individuals with conjunctivitis to practice good hygiene, such as frequent handwashing and avoiding touching their eyes, to prevent spreading the infection.

Viral conjunctivitis, often associated with respiratory infections, and bacterial conjunctivitis, commonly caused by different bacterial strains, can both spread easily in settings like schools or daycare centers where children are close together. The contagious nature of conjunctivitis emphasizes the importance of understanding how it spreads and taking precautions to mitigate further outbreaks.
