Viral Conjuctivitis is a hazard
Conjunctivitis is most commonly caused by viral infection, but bacterial infections, allergies, other irritants and dryness are also common etiologies for its occurrence. Both bacterial and viral infections are contagious. Commonly, conjunctival infections are passed from person-to-person, but can also spread through contaminated objects or water.
1. Bacterial conjunctivitis Bacterial conjunctivitis is an infection caused by bacteria, such as staphylococci, streptococci or haemophilus. These organisms may come from the patient's own skin or upper respiratory tract or they may be caught from another person with conjunctivitis.
2. Viral conjunctivitis Viral conjunctivitis is often associated with the common cold. This may be caused by a virus called 'adenovirus'. This type of conjunctivitis can spread rapidly between people and may cause an epidemic of conjunctivitis.
3. Chlamydial conjunctivitis This type of conjunctivitis is caused by an organism called Chlamydia trachomatis. This organism may also affect other parts of the body and can cause the sexually transmitted infection chlamydia.
4. Allergic conjunctivitis Allergic conjunctivitis is common in people who have other signs of allergic disease, such as hay fever, asthma and eczema. The conjunctivitis is often caused by antigens like pollen, dust mites or cosmetics.
5. Reactive conjunctivitis – chemical or irritant conjunctivitis Some people are susceptible to chemicals in swimming pools or to smoke or fumes, and this can cause an irritation of the conjunctiva with discomfort, redness and watering. In such cases these irritants should be avoided
