Eye Flu (Conjunctivitis): Symptoms, Care and Spread

"Eye flu," the common name for conjunctivitis, sweeps through Bangladeshi homes, schools and offices every monsoon, often passing from one family member to the next within days. It looks alarming because of the redness and discharge, but most cases are caused by a virus and clear up on their own with simple care. Knowing how to soothe the eyes, when drops are really needed, and how to stop the spread can protect your whole household. This article is general health information and does not replace advice from a qualified doctor.

What is conjunctivitis?

Conjunctivitis is inflammation of the conjunctiva, the thin clear layer covering the white of the eye and the inside of the eyelids. It can be caused by a virus, by bacteria, or by allergies. Viral conjunctivitis is the most common during the rainy season and is highly contagious, spreading through touch, shared towels and contaminated hands. Allergic conjunctivitis, by contrast, is not contagious and is triggered by dust, pollen or irritants.

What are the symptoms?

• Redness or a pink tinge in one or both eyes.
• Watering and a gritty, sandy feeling, as if something is in the eye.
• Itching or mild burning.
• Watery discharge in viral cases, or thicker yellow-green sticky discharge in bacterial cases.
• Eyelids stuck together in the morning.
• Mild sensitivity to light.

How does it spread so fast in the monsoon?

Viral eye flu spreads very easily through everyday contact. Touching an infected eye and then a doorknob, phone, towel or another person passes the virus along quickly. Crowded living, shared bedding and damp monsoon conditions help it move through a household or classroom in days. This is why one case at home so often becomes several. Frequent handwashing and not sharing personal items are the most effective ways to break the chain.

Home care for eye flu

Most viral conjunctivitis settles within one to two weeks with gentle care.

• Clean the eyes gently with cooled boiled water and a fresh piece of cotton, wiping from the inner to outer corner, using a separate piece for each eye.
• Apply a cold compress to ease swelling and discomfort.
• Use lubricating artificial tears for relief; ask your pharmacist or check the medicine directory rather than borrowing someone else's drops.
• Wash hands often and avoid touching or rubbing the eyes.
• Stop wearing contact lenses and eye make-up until the eyes are fully better.
• Rest the eyes and reduce screen time while symptoms last.

Do you need antibiotic eye drops?

Not usually. Viral conjunctivitis, which is the most common type, does not respond to antibiotics, just as a viral cold does not. Antibiotic drops only help bacterial conjunctivitis, which a doctor may suspect when there is thick, sticky yellow-green discharge. Using leftover or borrowed steroid eye drops without advice can be dangerous and may worsen some eye infections, so any drops beyond simple lubricants should be guided by a doctor.

How to stop it spreading at home

• Use a separate towel, pillow and bedding for the affected person.
• Wash hands thoroughly after touching the eyes or face.
• Do not share eye drops, make-up, glasses or handkerchiefs.
• Keep the affected person home from school or work for a few days while the eyes are weeping.
• Disinfect shared surfaces such as phones, taps and door handles.

When should you see a doctor?

See a doctor if you have eye pain, blurred vision that does not clear with blinking, marked sensitivity to light, very heavy yellow-green discharge, or symptoms that last beyond two weeks. Newborn babies with red, discharging eyes, anyone with a recent eye injury, and people with a weak immune system should be seen promptly. You can see a relevant specialist such as an eye doctor, and read more health tips on monsoon illness. Never delay care if your vision is affected.

Frequently Asked Questions

How long is eye flu contagious?

Viral conjunctivitis is usually contagious for as long as the eyes are red and watering, often up to one to two weeks. Frequent handwashing, not sharing towels and staying home while the eyes are weeping help protect others.

Should I use antibiotic drops for eye flu?

Most eye flu is viral and does not need antibiotics. Antibiotic drops only help bacterial cases, which a doctor may suspect with thick yellow-green discharge. Avoid borrowed or leftover drops, especially steroids, without medical advice.

Can I wear contact lenses with conjunctivitis?

No. Stop wearing contact lenses and eye make-up until the eyes are completely better, and replace or properly clean lenses and cases afterwards to avoid re-infection.

Is it safe to go to work or school with eye flu?

It is best to stay home for a few days while the eyes are red and weeping, since this is the most contagious period. Returning once the discharge settles, with good hand hygiene, reduces the risk of spreading it.
