Because colds and flu share many symptoms, it can be difficult or even impossible to tell the difference between them based on symptoms alone. Special tests can tell if a person is sick with flu.

Less common signs are a sore throat, headache, aches and pains, diarrhoea, a rash on skin, or discolouration of fingers or toes and red or irritated eyes.
But this may be changing because, as vaccines are doled out by the millions, people suffer a more mild disease. Data from the ZOE app shows that positive patients that use the app most commonl y have a headache and runny nose, reported by 73 per cent. It's followed by a sneezing 60 per cent , a sore throat 49 per cent and persistent cough 49 per cent. These symptoms were likely to occur alongside others.
Having a headache alone, for example, does not necessarily mean you have Covid. The Delta was the most prevalent in the UK - but Omicron now makes up close to 90 per cent of infections. As it grew in case numbers, evidence showed that its symptoms may be different to the original version of the virus, from Wuhan.

If you suspect Omicron infection, be sure to get tested as soon as possible.

As Gulick points out, getting booster shots is crucial. And if you are sick, or suspect you could be sick, stay home. Babcock acknowledges that there is social fatigue with the pandemic and its safety precautions—but says they remain important. When we let our guards down and skip out on booster appointments or throw away masks, we are giving the virus more opportunities to spread.
Even now, for people who haven't gotten vaccinated, they can still benefit from vaccination.
