Just like the coronavirus, the disease’s signs changed over time. Researchers have now identified a new primary symptom.
Over the past two and a half years, the coronavirus has evolved several times, and with the different variants, the symptoms that indicate infection have also changed. In the beginning, cough, fever, and loss of sense of smell and taste were clear indicators of infection, but now it can also be a cold.
Scientists from Great Britain observe and document this continuously in the context of the “Zoe Covid Symptom Study,” the most extensive study of this kind worldwide, in which already over four million humans participated.
Based on the ongoing documentation, the researchers have now identified a new main corona symptom: “At the moment, covid starts with a sore throat in two-thirds of people,” explained Tim Spector, co-founder of the study in an interview with “The Independent.” Other symptoms, such as fever and loss of smell, are “infrequent.”
And that worries the scientist because many people – especially older people – wouldn’t think they might have covid based on a sore throat. “They would say it’s a cold,” Spector suspects. People would, therefore, not get tested and thus unknowingly pass on the virus.
It’s a big problem given the rising numbers. “It looks like we’re at the beginning of the next wave,” Spector adds. That’s because the two new subvariants of Omicron, BA.2.75.2 and BQ.1.1, have also arrived in the United Kingdom. Two sublines escape the immune system relatively well.
The scientist said this could cause “real problems” for the UK; the health system is “on its knees” because winter is approaching.
