Experts have warned that a new rhinovirus could pose a health risk to vulnerable people due to symptoms that are similar to coronavirus.
Rhinovirus may be the reason for your cold-like symptoms, with people experiencing a headache or runny nose now being urged to stay at home despite a negative Covid test.
A spokesperson for the Department of Health has set out how to tell the difference between the two viruses to reduce the chance of spreading the infection to others, Belfast Live reports.
Signs of coronavirus may not be limited to the three original symptoms commonly described and could include a runny nose, sore throat or headache - all typical signs of a respiratory virus.
Government advice now states that anyone with cold-like symptoms should stay at home to and isolate to stop the rhinovirus spreading further.
They said: "Current official advice on COVID-19, as detailed on, already acknowledges that symptoms may vary and may not be limited to the three central symptoms identified at the outset of the pandemic.

COVID-19 symptoms “may be similar to the cold or flu” and “may vary for different age groups or different variants of the virus”.
"People with one of the three original symptoms of COVID (cough, temperature or loss of smell and taste) are still advised to stay at home and book a PCR test."
"If you have other symptoms of a respiratory virus (such as runny nose, sore throat or headache) you can take a LFD test.
"Even if you don’t have COVID, your symptoms may be caused by another respiratory virus such as rhinovirus which can be easily passed on to others.
"It is therefore advisable to stay at home if you can and reduce contact with others when you have respiratory virus symptoms to avoid spreading infection to others."
