Since the first cases of Covid were reported in the UK in 2020, patients have experienced a range of different symptoms. Many of us are aware of what were ruled to be the most prevalent signs in the early stages of the pandemic. However, since then the most likely symptoms have continued to change.
Not only is this due to the fact the virus has mutated several times, but also the vaccines have played a part.
The ZOE Health Study, which collates information from patients, found that the number of vaccines you have can determine which symptoms of Covid you are most likely to develop if you catch it.
According to the findings, tussis is among the top five symptoms in those who have had two vaccines.
Tussis is the medical term for a cough.
The study describes this symptom as “persistent”.
The other four top symptoms currently are:
- Sore throat
- Runny nose
- Blocked nose
- Headache.
The study explains: “The previous ‘traditional’ symptoms as still outlined on the government website, such as anosmia (loss of smell), shortness of breath and fever rank way down the list, at six, 29 and eight respectively.
“A persistent cough now ranks at number five if you’ve had two vaccine doses, so is no longer the top indicator of having Covid.
“Curiously, we noticed that people who had been vaccinated and then tested positive for COVID-19 were more likely to report sneezing as a symptom compared with those without a jab.”
Covid symptoms if you’ve had one vaccine
The ranking of top symptoms is slightly different among those who have had one vaccine.
Currently, the five most common signs are:
- Headache
- Runny nose
- Sore throat
- Sneezing
- Persistent cough.
The study says: “As we can see, after the protection from only one vaccine, one of the original indicators of a persistent cough has made the top five symptoms, but still comes below sneezing and a runny nose in rankings, which were previously thought to be unrelated to infection.”
Covid symptoms if you are unvaccinated
Symptoms among the unvaccinated are closer to the first symptoms reported but have still changed since the start of the pandemic.
They are:
- Headache
- Sore throat
- Runny nose
- Fever
- Persistent cough.
“Loss of smell comes in at number nine and shortness of breath comes far down the list at number 30, indicating the symptoms as recorded previously are changing with the evolving variants of the virus,” the study adds.
“As we have found, even people who have had one or two doses of the vaccination can still be susceptible to contracting Covid, and the symptoms and severity differ depending on how many vaccinations you’ve had, if any.”
It comes as the Office for National Statistics reported a decrease in cases in the UK in the week ending November 8.
In England, the estimated number of people testing positive for COVID-19 was 940,700 – or 1.73 percent of the population (a decrease from 2.43 percent in the previous week).
In Wales 56,000 people were estimated to have tested positive, while this figure was 34,200 in Northern Ireland and 97,500 in Scotland – all decreases on the previous week.
However, health experts are still warning of a difficult winter ahead with fears of a “tripledemic” caused by Covid, flu and Respiratory Syncytial Virus Infection.
