What is the common cause of viral conjunctivitis?

  1. Adenovirus

  2. Herpes Simplex Virus

  3. Varicella-zoster Virus

  4. Human Immunodeficiency Virus

The correct answer is: Adenovirus

Viral conjunctivitis is an inflammation of the outermost layer of the eye caused by a virus. While all the options listed are viruses, the most common cause is adenovirus, which can also cause respiratory infections. Herpes simplex virus and varicella-zoster virus are less common causes of viral conjunctivitis, and are more commonly associated with genital herpes and chickenpox, respectively. Human immunodeficiency virus (HIV) can also cause conjunctivitis, but it is typically associated with more severe eye conditions such as retinopathy.
