Viral Conjunctivitis (Pink Eye): Contagious? Treatment & Prevention in Seoul
Board-Certified Eye Care in Yeongdeungpo, Guro, Gasan & Gwanak, Seoul
Q. Is pink eye contagious and how is it treated?
Yes — viral conjunctivitis (pink eye) is highly contagious, typically spreading through direct contact with eye secretions or contaminated surfaces for up to 10–14 days after symptoms begin. There is no cure for the virus itself; treatment focuses on cold compresses, lubricating eye drops, and strict hygiene to control symptoms and prevent spreading it to others in your home, office, or school in Seoul.
Q. What is viral conjunctivitis?
Viral conjunctivitis is inflammation of the conjunctiva — the clear membrane covering the white of the eye and inner eyelid — caused most often by adenovirus. It is one of the most common reasons patients visit our clinic in Yeongdeungpo-gu, especially during seasonal outbreaks in spring and early summer. Unlike bacterial conjunctivitis, viral pink eye usually produces watery rather than thick, colored discharge, and it often begins in one eye before spreading to the other within a few days.
Q. What are the symptoms of pink eye?
- Redness in one or both eyes
- Watery discharge and excessive tearing
- Gritty or burning sensation, as if sand is in the eye
- Swollen, sticky eyelids (especially after sleep)
- Sensitivity to light (photophobia)
- Occasionally, swollen lymph nodes in front of the ear
Pink Eye by the Numbers in Korea
- ▸ Viral conjunctivitis accounts for up to 80% of acute conjunctivitis cases seen in Korean ophthalmology clinics
- ▸ Outbreaks in Seoul tend to peak between March–June and September–November
- ▸ Adenoviral conjunctivitis remains contagious for 10–14 days after symptom onset
- ▸ Patients from Guro and Gasan often present after workplace or school outbreaks due to close-contact settings
Q. How is viral conjunctivitis treated?
There is no antiviral medication that directly cures adenoviral conjunctivitis, so treatment is supportive. At Nunehim Eye Center, we typically recommend frequent artificial tears to flush irritants and soothe the surface, cold compresses several times a day to reduce swelling and discomfort, and strict avoidance of touching or rubbing the eyes.
In more severe cases with significant inflammation or the formation of pseudomembranes, we may prescribe a short course of topical steroid drops under close monitoring, since prolonged steroid use can raise eye pressure or prolong viral shedding. Antibiotic drops are not effective against the virus but may occasionally be used if a secondary bacterial infection is suspected.
Q. How long is pink eye contagious?
Viral conjunctivitis is typically most contagious during the first week of symptoms and can remain transmissible for up to two weeks. The virus spreads through direct contact with eye discharge, contaminated hands, towels, pillowcases, or shared items like makeup and phone screens. Patients commuting through busy areas like Yeongdeungpo and Guro Digital Complex should be especially mindful of hand hygiene on public transportation during an outbreak.
Q. When should I see a doctor in Seoul?
- Severe eye pain or a feeling that something is stuck in the eye
- Vision changes or blurred vision that doesn’t clear with blinking
- Intense light sensitivity
- Symptoms lasting more than 7–10 days without improvement
- Thick yellow or green discharge (suggesting bacterial infection)
- Any involvement of young children, contact lens wearers, or immunocompromised individuals
Early Stage (Days 1–3)
Redness, watery discharge, and irritation begin, often in one eye first.
Peak Stage (Days 4–7)
Symptoms are most intense and most contagious; discharge and swelling peak.
Recovery (Days 8–14)
Symptoms gradually resolve; the contagious period ends around day 10–14.
A Note from Dr. Daniel Baik
As a board-certified ophthalmologist practicing in Yeongdeungpo-gu, I see viral conjunctivitis cases rise sharply every spring and fall. The most important thing I tell my patients in Guro and Gasan is that hygiene — not medication — is what stops the spread. Resist the urge to rub your eyes, wash your hands frequently, and avoid sharing towels until symptoms fully resolve.
❓ Frequently Asked Questions
Q. Can I go to work or school with pink eye?
Most workplaces and schools in Korea recommend staying home while discharge and redness are present, typically 3–7 days, since viral conjunctivitis spreads easily in shared spaces like offices in Gasan or classrooms in Guro.
Q. Is viral conjunctivitis the same as bacterial conjunctivitis?
No. Viral conjunctivitis usually causes watery discharge and often starts in one eye, while bacterial conjunctivitis tends to cause thicker, colored discharge in both eyes. An eye exam is the most reliable way to tell them apart.
Q. Can adults get pink eye, or is it only in children?
Adults are frequently affected, especially those working in close-contact environments such as offices, gyms, and public transportation hubs common throughout Yeongdeungpo and Gwanak.
Q. Will I need antibiotics?
Antibiotics do not treat viral conjunctivitis. They may only be prescribed if your ophthalmologist suspects a secondary bacterial infection.
Q. Can I wear contact lenses while I have pink eye?
No. Contact lens wear should be paused until symptoms have fully resolved and your ophthalmologist confirms the eye has healed, to avoid worsening irritation or corneal complications.
Q. How can I prevent spreading pink eye to my family?
Wash hands frequently, avoid sharing pillows, towels, or eye makeup, disinfect frequently touched surfaces, and avoid close contact until discharge has resolved.
Q. Does pink eye cause permanent vision damage?
In most cases, no. However, severe adenoviral infections can occasionally cause temporary corneal haze that affects vision for several weeks, which is why prompt evaluation matters if symptoms are severe or prolonged.
