Some germs, rare, can be very serious, such as Pseudomonas aeruginosa in patients with contact lenses, or diphtheria bacilli in children 1 to 4 years in a context of deterioration in general.Viral conjunctivitis

Viral conjunctivitis is often associated with colds, and the most frequent cause is a virus called adenovirus. Highly contagious, this type of conjunctivitis can spread rapidly from person to person and even be responsible for epidemics of conjunctivitis. Other viruses can cause conjunctivitis, the most serious of which is the varicella-zoster virus, which causes the so-called ophthalmic herpes.
