Sore throat, headache, runny nose and cough are the main symptoms that can show the picture of covid-19.
This is the result of a report containing information on 17,500 people who tested positive in the UK last week.
Data obtained using the Zoe Covid app was analyzed in collaboration with researchers at King’s College London and with support from the NHS, the country’s public health system.
The study also found that fever and loss of smell or taste, which were the much more common symptoms of the disease a few months ago, are now becoming less common.
Other ailments such as hoarseness, sneezing, fatigue and muscle pain also rose in the rankings of disease symptoms.
According to Zoe’s study data, in descending order, the top 20 symptoms of covid-19 are:
The information matches the findings of other recent studies.
The React-1 study, for example, randomly selects around 150,000 people in the UK each month. They all do rapid antigen tests.
Their latest results show that the most common symptoms of covid-19 have changed significantly throughout the pandemic.
Scientists assess that this may be related to mutations of the coronavirus.
Several variants of the pathogen have emerged since the original version was first detected in Wuhan, China. The newest is micron.
React-1 researchers at Imperial College London say the new variants show less loss of smell and taste.
However, those who are infected report symptoms more typical of the common cold or flu.
They analyzed early versions of the omicron, known as BA.1 and BA.2, which went mainstream as of March 2022.
Since then, two new highly infectious, omicron-derived subvariants, designated BA.4 and BA.5, have gained ground and are responsible for the majority of new infections.
While it is currently estimated that 2.7 million people – one in 25 people – in the UK have been infected with Covid-19, there has been an increase in cases recently in Latin America and various countries around the world.
Tim Spector, who conducted the study with the Zoe app, assures that “covid is still out of control”.
“Even people who have had a past infection and are fully vaccinated can get the virus.”
“We have to decide whether it’s really worth going to big events, working in the office, or using public transport during rush hour,” says the expert.
