Introduction

Under normal circumstances, swine flu refers to Influenza A (H1N1). Whether infection with Influenza A (H1N1) causes red eyes mainly depends on whether the virus directly invades the ocular tissues and causes inflammation. If the virus infects the eye or there are external irritants, the eyes may become red; however, if the virus does not affect the eyes and there are no external irritants, the eyes typically remain unaffected.

Generally speaking, "swine flu" refers to influenza A. Whether the eyes turn red after infection with influenza A mainly depends on whether the influenza A virus directly invades ocular tissues and causes inflammation. If the virus infects the eye or there are external irritants, the eyes may become red; however, if the virus does not affect the eyes and there are no external stimuli, the eyes typically do not turn red. If discomfort occurs, timely medical attention is recommended. Detailed analysis is as follows:

When an influenza A virus infection causes ocular inflammation, such as viral conjunctivitis, the patient's eyes may become red. This is because after the ocular tissues are infected by the virus, a localized immune response occurs, causing dilation and congestion of blood vessels in the eye, resulting in redness. This may also be accompanied by symptoms such as itchy eyes, tearing, and increased eye secretions. Additionally, if patients frequently rub their eyes due to fever or general discomfort during infection, this may also lead to conjunctival congestion and red eyes.

If the influenza A virus primarily affects areas such as the respiratory tract without involving the ocular tissues, and the patient does not rub their eyes or experience other external irritations, the eyes typically do not become red. In such cases, the main symptoms include typical flu symptoms such as fever, cough, sore throat, runny nose, nasal congestion, body aches, and fatigue, while the eyes show no significant abnormalities.

It is important to wash hands frequently, especially after touching public items and before eating, to avoid touching the eyes, mouth, and nose with hands, thus reducing the chance of viral infection. At the same time, maintaining a regular routine, ensuring adequate sleep, engaging in physical exercise, and maintaining a balanced diet can enhance immunity and reduce the risk of contracting influenza A and other diseases.
