Is conjunctivitis contagious?
Disease description:
I've had conjunctivitis these past few days, causing my eyes to become red and painful, along with a constant buildup of layer-like discharge. I'm really worried about passing it on to my child, especially since children have weaker immune systems. I'd like to know—can conjunctivitis be contagious?

Whether conjunctivitis is contagious depends on its type.
1. Viral conjunctivitis: Highly contagious, primarily spreading through direct contact. For example, if a patient rubs their eyes and then touches other people or objects, the virus may be transmitted. Therefore, individuals with viral conjunctivitis should maintain good personal hygiene to avoid spreading the infection.
2. Bacterial conjunctivitis: Also somewhat contagious, though less so than the viral form. Patients should still take precautions to prevent cross-infection, such as using separate towels and handkerchiefs, and regularly disinfecting personal items.
3. Allergic conjunctivitis: Generally not contagious, as it results from an immune response to allergens and is unrelated to bacteria or viruses.
If you have concerns or experience worsening symptoms, seek medical attention promptly.
