Experts have revealed that 'sore and itchy eyes' could be an early sign of coronavirus.
While the more common symptoms are a persistent cough, fever and loss of taste and smell - a new study has uncovered that eye irritation could be a potential sign of Covid-19.
Anglia Ruskin University carried out the study, examining data from 83 coronavirus patients.
The researchers found that a cough, fever, fatigue and loss of taste and smell were the most common complaints.
However, they also discovered that 18 per cent reported light sensitivity - known as photophobia - while 17 per cent had itchy eyes and 16 per cent suffered sore eyes.
Many patients reported having eye issues within two weeks of other Covid symptoms, The Sun reports.
Health officials think conjunctivitis develops in around one to three per cent of coronavirus patients, according to the American Academy of Ophthalmology.
Chelsey Earnest, a nurse at the Life Care Centre in Washington, said that red eyes are the ‘single most important’ sign that patients have COVID-19.
Speaking to CNN she explained: “They have, like...allergy eyes. The white part of the eye is not red. It's more like they have red eye shadow on the outside of their eyes.”
However, the American Academy of Ophthalmology said this does not mean you should panic if you see someone with 'pink eye'.
