What is keratoconjunctivitis due to adenovirus?
Epidemic keratoconjunctivitis (EKC) is a viral conjunctivitis caused by a group of adenoviruses. This family of adenoviruses contains different serotypes that can also cause pharyngoconjunctival fever and nonspecific follicular conjunctivitis. EKC is highly contagious and has a tendency to occur in epidemics.
What is adenovirus of the eye?
Adenoviral infection presents with sudden onset of red eye(s) with a watery discharge often associated with a sore throat. The differential diagnosis includes bacterial (including chlamydial) conjunctivitis, other viral causes of conjunctivitis and, possibly, allergic conjunctivitis.
What strain of adenovirus causes pink eye?
Adenoviruses are common viruses that cause a range of illnesses. Adenovirus 4 can cause more severe symptoms — such as sore throat, fever, cough, pink eye (conjunctivitis), pneumonia and gastrointestinal symptoms like nausea, vomiting or diarrhea — than other strains of adenoviruses.
How long is adenovirus conjunctivitis contagious?
The period of contagion lasts about 3 weeks. 1 Incubation period for Ad-CS is about 10 days (range 7-16 days) prior to the onset of symptoms. Symptoms typically persist for 7 to 28 days.
What causes keratoconjunctivitis?
Keratoconjunctivitis is a group of inflammatory eye conditions involving the cornea and the conjunctiva. Allergies, viruses, and bacteria are among the causes. Some types are associated with congenital or autoimmune disorders.
How long do corneal infiltrates take to heal?
The size of the infiltrate is important. If a patient comes into your office with a 1-day history of an infiltrate and it is small in size, we usually know it will do well and heal within a 5- to 7-day time period.
How do you get adenovirus?
Adenovirus is easily spread by our hands to our eyes, nose, and mouth, so thoroughly washing with soap and water for 20 seconds—especially before and after touching your face or after using the bathroom—can really reduce your risk. Just like with the cold and flu, avoid close contact with those who are sick.
How does an adenoviral infection cause red eye?
Adenoviral infection presents with sudden onset of red eye(s) with a watery discharge often associated with a sore throat. The differential diagnosis includes bacterial (including chlamydial) conjunctivitis, other viral causes of conjunctivitis and, possibly, allergic conjunctivitis.
Are there any antiviral agents for adenoviral ocular infections?
As no specific antiviral agent exists for adenoviral ocular infections, treatment is supportive and robust hygiene measures need to be implemented to reduce its spread; there is no role for topical antibiotics. Eye health workers are commonly faced with adenoviral infection of the eye as a cause of bilateral conjunctivitis.
When does adenoviral conjunctivitis spread to the contralateral eye?
Symptoms usually begin and predominate in one eye, and within a few days, have spread to the contralateral eye. A history of antecedent upper respiratory tract infection or close contact with someone with a “red eye” is common. When adenoviral eye infections further involve the cornea, the term epidemic keratoconjunctivitis (EKC) is used.
Which is the most serious form of adenovirus?
Epidemic keratoconjunctivitis (EKC) Epidemic keratoconjunctivitis (EKC) is the most serious of the adenoviral infections. It is associated with adenovirus serotypes 8 and 19, although associations with other types have been reported.4,5Transmission occurs amongst individuals in close contact with one another.
