How many days does it take to recover from acute conjunctivitis?

Acute conjunctivitis typically resolves within 1–2 weeks, with bacterial types recovering faster and viral types taking slightly longer. If in doubt, it is recommended to seek medical advice promptly. Detailed analysis is as follows:

Bacterial acute conjunctivitis, when treated promptly with appropriate antibiotic medications (such as ocular gels or eye drops) along with proper eye hygiene and care, usually shows significant symptom relief within about one week and is largely cured within two weeks. This type produces abundant discharge, but with standardized treatment, inflammation is rapidly controlled and long-term complications are rare.

Viral acute conjunctivitis (such as that caused by adenovirus) lacks specific antiviral treatments and therefore has a relatively longer recovery period—typically around two weeks, though severe cases may extend up to three weeks. This type is often accompanied by tearing and a foreign body sensation. Strict isolation and protective measures are necessary to prevent transmission, and recovery relies on the body's immune response combined with symptomatic care.

During the course of acute conjunctivitis, patients should follow prescribed medication regimens and maintain strict separation of personal items. If symptoms persist beyond two weeks or if vision deteriorates, prompt re-evaluation is necessary. Avoid rubbing the eyes and maintain good ocular hygiene to promote rapid resolution of inflammation.
