What are the two types of conjunctivitis?

• A. Viral and fungal conjunctivitis
• B. Bacterial and fungal conjunctivitis
• C. Viral and allergic conjunctivitis
• D. Viral and bacterial conjunctivitis

Answer: (D)

The two primary types of conjunctivitis are viral and bacterial conjunctivitis. Viral conjunctivitis is often caused by infections such as adenoviruses, and it is characterized by symptoms that include redness, watery discharge, and an often contagious nature. Bacterial conjunctivitis, on the other hand, is typically caused by bacteria such as Staphylococcus or Streptococcus, leading to symptoms such as purulent discharge and matting of the eyelids, particularly upon waking. Recognizing these two types is essential for proper diagnosis and treatment. Viral conjunctivitis generally resolves on its own, while bacterial conjunctivitis may require antibiotic treatment. Despite the presence of allergic conjunctivitis, which involves an allergic response to substances like pollen or pet dander, it is considered a separate category not classified under the viral or bacterial types. Therefore, in the context of common classifications, viral and bacterial conjunctivitis are the correct pair, making this choice accurate.
