Which viral or bacterial infection shows the following symptoms: eye itchiness, red or pink appearance of the eye, discharge from the eye?

The symptoms described - eye itchiness, red or pink appearance of the eye, and discharge from the eye - are commonly associated with Conjunctivitis, also known as "pink eye". Conjunctivitis can be caused by both viral and bacterial infections.

Here are the steps to identify it:

1. Check for redness in the white of the eye or inner eyelid.
2. Check for increased amount of tears.
3. Check for thick yellow discharge that crusts over the eyelashes, especially after sleep.
4. Check for green or white discharge from the eye.
5. Check for itchy or burning eyes.
6. Check for blurred vision.
7. Check for increased sensitivity to light.

If these symptoms are present, it's likely the person has conjunctivitis. However, it's important to consult with a healthcare professional for an accurate diagnosis and treatment.
