In brief: Sometimes
Conjunctivitis can be bacterial, in which case it's contagious and needs to be treated with antibiotics.
It can be viral, and then it's sometimes treated with medicines for inflammation. Viral conjunctivitis is contagious too. It can be allergic and treated with antihistamines, but allergic conjunctivitis is not contagious.
