Scientists are diligently studying two new variants of the coronavirus, HV.1 and JN.1, to better understand their characteristics and methods of transmission. One of the most distinctive symptoms involves eyes.

Covid-19 symptoms

Dr Bruno Silvester Lopes, a microbiology specialist from Teesside University, explains that even with the diversity of Covid-19 variants, their symptoms remain quite similar.

The World Health Organization (WHO) has listed eye irritation as an uncommon symptom of Covid-19. Dr. Lopes suggests that red, teary, swollen, or itchy eyes could be indicative of an infection with the newer virus strains.

Be mindful of your eyes. They can reveal signs of illness.

The JN.1 variant, a mutation of the dominant Omicron subvariant in 2022, may cause such reactions. Initially identified in Luxembourg, it has since been observed in the UK, Europe, and the United States.

Mutations of the JN.1 variant and resistance to neutralization

Dr Lopes points out that the JN.1 variant contains specific mutations that could impede the human immune response. Certain changes in the JN.1 strain suggest increased effectiveness in infecting cells and spreading in tissues, faster reproduction, and diminished recognition by T cells, along with a potential to evade antibodies.

Eye discomfort could be a sign of other diseases. Do not dismiss such symptoms.

Understanding these relationships is crucial in developing efficient protective methods against the virus and its new variants.

What steps to take when symptoms appear?

People who exhibit symptoms of Covid-19 (such as fever, headache, runny nose, red eyes, fatigue) ought to get tested immediately.

Blurred vision can be a manifestation of other illnesses, including cancer.

Experts also advise maintaining good ventilation at home, frequent and thorough hand washing, and staying home for at least five days. To help prevent the spread of infection, it's important to consider wearing a mask while around others, even if you're only experiencing mild symptoms that resemble a common cold!
