The question remains: What are the main symptoms that appear in all strains of the virus? ..
This is what the British “express” reveals, that genetic changes in viruses are not new, but SARS-CoV-2 – the virus that causes Covid-19, has destroyed the world and its mutations threaten to overcome the circulating vaccines to stop it.
But a new analysis of the data gathered from the ZOE COVID Symptom Study app reduces many of the concerns about new mutations.
The latest analysis of the symptom data collected from the ZOE COVID Symptom Study app shows no statistically significant differences in the type, severity or duration of coronavirus symptoms due to the novel coronavirus variant B.1.1.7.
Coronavirus variant B.1.1.7 is the mutation that was first detected in Kent, UK.
Variant B.1.1.7 was first identified in September 2020, and has rapidly spread across the UK and elsewhere, while the results are reassuring, Claire Steves, Principal Investigator, emphasized the importance of responding to a possible set of symptoms.
Steves highlighted five symptoms of the virus that are common in both the old and new variants.
“It is important to emphasize the set of symptoms that can be caused by both the new and the old variant, such as headache and sore throat, in addition to the classic triad of coughing, fever and loss of smell,” she said.
How did Steves and her team compare the characteristics of the old and new variant?
To find out if the new Kent strain of the virus affects people’s COVID-19 symptoms, researchers led by Sebastian Urselyn and Claire Steves at King’s College London analyzed more than 65 million health reports submitted to the ZOE COVID Symptom Study app. By 1.76 million users between Sep 28 and Dec 27, 2020.
This is the period when the new variant has spread among the population, especially in London, southeast England and eastern England.
Almost half a million users reported taking a coronavirus swab test during this time, with 55,192 users reporting a positive result.
The researchers looked at how many people reported experiencing any of the 14 main symptoms of COVID-19, the total number of symptoms each individual reported (an indication of the severity of their disease) and whether the symptoms lasted 28 days or longer.
They also counted self-reported hospital admissions and potential re-infections, as someone reported two positive COVID-19 tests separated by at least 90 days.
They then compared this information with the estimated prevalence of the new variant in Scotland, Wales and seven regions based on data from the COG-UK Genetic Monitoring Program and the Public Health Testing Service England.
After adjusting the data to take into account age and gender, as well as local temperature and humidity, the analysis showed that there were no statistically significant differences in type, number, or duration of symptoms between areas of high prevalence of B.1.1.7 compared to those with lower prevalence and that this did not change As the new variable spreads.
There was also no difference in the proportion of reported hospitalizations and re-infection cases.
The researchers identified 249 possible cases of re-infection during the study period, which represents a re-infection rate of 0.7%, which is comparable to previous studies of previous virus variants.
The researchers said: “This is a positive sign that the immunity built up through vaccination against ancient variants could also be protective against the new strain B.1.1.7.
Finally, the researchers confirmed that the new variant was more easily transmitted than the current virus versions, increasing the R value (a measure of transmissibility) by about a third (35%).
How do you respond to symptoms
If you have any of the main symptoms of Coronavirus (Covid-19), you should get tested as soon as possible, and stay home until you get the result.
You and anyone you live with should stay home and not have visitors until you get the test result – just leave your home for the test.
