Conjunctivitis is contagious, so it is not recommended to go to kindergarten to avoid infecting other children.

1. Causes of conjunctivitis

Most of the surface of the conjunctiva is exposed to the outside world and comes into contact with a variety of microorganisms and the external environment. Although the specific and non-specific protective mechanisms of the ocular surface It has certain ability to prevent infection and localize infection.

But when these defense capabilities weaken or external pathogenic factors increase, inflammation of the conjunctival tissue will occur, that is, conjunctivitis, the legendary "pink eye disease."

2. Nature of conjunctivitis

The causes of conjunctivitis can be divided into two categories: infectious and non-infectious according to their different properties.

(1) Infectiousness: conjunctival inflammation caused by infection by pathogenic microorganisms.

(2) Non-infectious: allergic inflammation (the most common) caused by local or systemic allergic reactions, external physical and chemical factors, such as: light, various chemicals, dust, pollen, etc. can become the cause of disease.

3. Clinical manifestations

Conjunctival congestion and increased secretions are the common characteristics of various conjunctivitis. Inflammation can occur in one eye or both eyes at the same time/sequentially. Symptoms of conjunctivitis include foreign body sensation, burning sensation, itching, photophobia, tearing, and increased secretion. If you have eye pain or pain in the iris and ciliary body, it indicates that inflammation has spread to the cornea.

How to prevent conjunctivitis in children?

1. Wash hands frequently and be hygienic

We must cultivate the habit of washing hands frequently and loving cleanliness in children. Children like to touch things everywhere and come into contact with many unhygienic toys, objects, etc. Parents should teach their children to wash their hands frequently from an early age and not to rub their eyes with dirty hands.

2. Avoid cross-infection

When a classmate in the school where your child is studying suffers from conjunctivitis, you must pay attention to the occurrence of cross-infection. Of course, children who have already contracted conjunctivitis should consider other children and choose to isolate themselves and not go to school for the time being to avoid spreading the germs to other children and others.

3. Reduce exposure to allergens

For children who have had a history of conjunctivitis in the past, exposure to allergens should be reduced. Only by taking protective measures can the chance of contracting conjunctivitis be truly reduced.

4. Enhance physical fitness

Children have strong growth and metabolism and need to strengthen their physical fitness, improve resistance, and reduce the risk of infection.
