Risk factors
By Mayo Clinic staffRisk factors for pink eye include:
- Exposure to an allergen for allergic conjunctivitis
- Exposure to someone infected with the viral or bacterial form of conjunctivitis
Both viral and bacterial conjunctivitis are common among children and are very contagious. Someone with conjunctivitis may be contagious for seven to 14 days after signs and symptoms first appear.
People who wear contact lenses, especially extended-wear lenses, may be more prone to conjunctivitis.
