The emergence of the new variants of Covid-19 has seen the symptoms to look out for becoming less clear. Symptoms which became a clear sign of coronavirus in the early days may be altered, it’s been reported, depending on which type of infection a patient has.
Loss of smell
Approximately 19 percent linked to original variant.
Approximately 16 percent linked to UK variant.
Loss of taste
Approximately 18 percent linked to original variant.
Approximately 15 percent linked to UK variant.
Headaches
The ONS study found little to no difference between the two variants.
Shortness of breath
The ONS study found little to no difference between the two variants.
Abdominal pain
The ONS study found little to no difference between the two variants.
Diarrhoea
The ONS study found little to no difference between the two variants.
In a study published in the BMJ, sore throat, fatigue and myalgia being the common symptoms to spot in the new UK variant was further analysed.
The study noted: “People infected with the new variant of covid-19 discovered in the South East of England (known as B.1.1.7) are more likely to have a cough, sore throat, fatigue, or myalgia than those infected with other variants, the Office for National Statistics has reported.
“The data, published 27 January, also show that people with the new variant are less likely to experience a loss of sense of smell or taste. These findings have prompted some doctors to call for the official covid-19 symptom list to be reviewed and potentially expanded—something that has not happened since May 2020.”
The report, which covered cases in England from 15 November 2020 to 16 January 2021, said, “Loss of taste and loss of smell were significantly less common in new variant compatible positives than triple positives, whereas other symptoms were more common in new variant compatible positives, with the largest differences for cough, sore throat, fatigue, myalgia, and fever.
“There is no evidence of difference in gastrointestinal symptoms, shortness of breath, or headaches.”
Richard Tedder, senior research investigator in medical virology at Imperial College London, said that the new data on symptoms could explain why B.1.1.7 is more transmissible.
“The fact that it has been reported that the second wave viruses, usually called variants, are more likely to cause symptoms of upper respiratory tract infection, i.e., coughs and colds, may indicate that a trivial difference in the way the virus may cause disease symptoms could cause more easy transmission between people.”
