Pink Eye (Conjunctivitis) in Children: Types, Home Care, and When to See a Doctor

The three main types and how they differ

Viral conjunctivitis is the most frequent type and is often associated with a cold or respiratory illness 1Ref 1Mahoney MJ, Bekibele R, Notermann SL, Reuter TG, Borman-Shoap EC (2023).Pediatric Conjunctivitis: A Review of Clinical Manifestations, Diagnosis, and Management.Differentiation of viral, bacterial, and allergic conjunctivitis by discharge type and associated symptoms; antibiotic benefit modest (approx. 1 day shorter); most cases self-resolving within 7–10 days. Discharge is usually watery or slightly mucousy, and redness may affect both eyes (though it often starts in one). It is highly contagious person-to-person and typically runs its course in one to two weeks without specific treatment. Most children with viral pink eye improve after five to six days without antibiotics 2Ref 2American Academy of Pediatrics (HealthyChildren.org) (2013).Pinkeye (Conjunctivitis).AAP guidance on newborn eye prophylaxis, school return policies (24-hour antibiotic requirement for bacterial form), and home care steps including separate cloths per eye.

Bacterial conjunctivitis tends to produce thicker, more purulent (pus-like) discharge — yellow or green — that can cause the eyelids to stick together after sleep 1Ref 1Mahoney MJ, Bekibele R, Notermann SL, Reuter TG, Borman-Shoap EC (2023).Pediatric Conjunctivitis: A Review of Clinical Manifestations, Diagnosis, and Management.Differentiation of viral, bacterial, and allergic conjunctivitis by discharge type and associated symptoms; antibiotic benefit modest (approx. 1 day shorter); most cases self-resolving within 7–10 days. Antibiotic eye drops or ointment may shorten symptom duration by approximately one day but carry risks of adverse reactions and antibiotic resistance; many mild cases resolve naturally within seven to ten days 3Ref 3American Academy of Ophthalmology (2023).Conjunctivitis Preferred Practice Pattern 2023.Evidence that mild bacterial conjunctivitis is frequently self-limiting; guideline basis for when antibiotic drops are indicated versus when watchful waiting is appropriate.

Allergic conjunctivitis is not contagious and is driven by allergens like pollen, pet dander, or dust. It typically causes intense itching, watery discharge, and redness in both eyes simultaneously, often alongside other allergy symptoms like a runny nose 1Ref 1Mahoney MJ, Bekibele R, Notermann SL, Reuter TG, Borman-Shoap EC (2023).Pediatric Conjunctivitis: A Review of Clinical Manifestations, Diagnosis, and Management.Differentiation of viral, bacterial, and allergic conjunctivitis by discharge type and associated symptoms; antibiotic benefit modest (approx. 1 day shorter); most cases self-resolving within 7–10 days. It does not involve fever.

Newborns: a special situation

Eye discharge in a newborn — especially in the first weeks of life — is handled differently than in older children. Newborns can develop conjunctivitis from infections acquired during birth, some of which require prompt treatment 2Ref 2American Academy of Pediatrics (HealthyChildren.org) (2013).Pinkeye (Conjunctivitis).AAP guidance on newborn eye prophylaxis, school return policies (24-hour antibiotic requirement for bacterial form), and home care steps including separate cloths per eye. A pediatrician should evaluate any significant eye redness or discharge in an infant under a few months of age. The AAP recommends erythromycin eye ointment at birth to prevent one specific bacterial cause 2Ref 2American Academy of Pediatrics (HealthyChildren.org) (2013).Pinkeye (Conjunctivitis).AAP guidance on newborn eye prophylaxis, school return policies (24-hour antibiotic requirement for bacterial form), and home care steps including separate cloths per eye.

Home comfort measures

For viral and allergic conjunctivitis, soothing the eye at home is the main focus while the body manages the cause 1Ref 1Mahoney MJ, Bekibele R, Notermann SL, Reuter TG, Borman-Shoap EC (2023).Pediatric Conjunctivitis: A Review of Clinical Manifestations, Diagnosis, and Management.Differentiation of viral, bacterial, and allergic conjunctivitis by discharge type and associated symptoms; antibiotic benefit modest (approx. 1 day shorter); most cases self-resolving within 7–10 days:

• Gently wipe discharge from the eyelid (wiping outward, away from the nose) with a clean damp cloth
• Use a separate cloth for each eye to avoid spreading infection
• Cool or warm compresses applied gently to closed eyelids can relieve discomfort
• Wash hands thoroughly before and after touching the eye area
• For allergic conjunctivitis, reducing allergen exposure helps; the pediatrician can advise about appropriate topical or oral antihistamines for older children

School and daycare: when can a child return?

Many schools and daycares have specific policies about pink eye. In general 2Ref 2American Academy of Pediatrics (HealthyChildren.org) (2013).Pinkeye (Conjunctivitis).AAP guidance on newborn eye prophylaxis, school return policies (24-hour antibiotic requirement for bacterial form), and home care steps including separate cloths per eye:

• Viral conjunctivitis: Exclusion policies vary; since the underlying illness (often a cold) is the contagious part, some programs allow return once general symptoms improve.
• Bacterial conjunctivitis: Many programs require that a child has been on antibiotic drops for a defined period (often 24 hours) and that discharge has decreased before returning.
• Allergic conjunctivitis: Not contagious; return to school is not restricted.

It is worth checking with the specific school or daycare program, as policies differ.
