Chills, appetite loss, headache may also be COVID-19 symptoms: UK study

London: A study of over one million folks in England has revealed further signs linked with having coronavirus, which may embody chills, lack of appetite, headache and muscle ache.

While these wider signs have been famous along with the recognized or so-called traditional signs of lack of sense of odor and style, fever and new persistent cough, round 60 per cent of contaminated folks didn’t report any signs within the week main as much as their check, the Imperial College London led Real-time Assessment of Community Transmission (REACT) study revealed on Wednesday.

“These new findings suggest many people with COVID-19 won’t be getting tested – and therefore won’t be self-isolating – because their symptoms don’t match those used in current public health guidance to help identify infected people,” mentioned Professor Paul Elliott, director of the REACT programme at Imperial.

“We understand that there is a need for clear testing criteria, and that including lots of symptoms which are commonly found in other illnesses like seasonal flu could risk people self-isolating unnecessarily. I hope that our findings on the most informative symptoms mean that the testing programme can take advantage of the most up-to-date evidence, helping to identify more infected people,” he mentioned.

Swab checks and questionnaires collected between June 2020 and January 2021 as a part of the study confirmed that amongst these different signs, chills, lack of appetite, headache and muscle aches have been collectively most strongly linked with being contaminated, alongside the 4 so-called traditional signs.

Having any of those different signs or the traditional ones, both alone or together, was related to infection with the coronavirus and the extra signs folks confirmed the extra possible they have been to check constructive.

The study also discovered that there was variation in signs with age. While chills have been linked with testing constructive throughout all ages, complications have been reported in younger folks aged 5-17, appetite loss in 18-54 and 55+, and muscle aches in folks aged 18-54. Infected 5-17-year-olds have been also much less prone to report fever, persistent cough and appetite loss in contrast with adults.

The analysis also explored whether or not the emergence of the UK’s new coronavirus variant, first recognized in Kent, was linked with a distinct profile of signs. While signs have been broadly related, in January this yr in comparison with November-December 2020, loss or change to sense of odor was much less predictive of getting COVID-19, whereas the proportion of individuals testing constructive with a brand new persistent cough appeared to be elevated.

“As the epidemic progresses and new variants emerge, it’s essential that we keep monitoring how the virus affects people so that testing programmes meet changing needs,” mentioned Dr Joshua Elliott, from Imperial College London’s School of Public Health.

“We hope that our data will help inform testing guidance and the development of systems which could help better identify people who should take a COVID-19 test based on their symptoms,” he mentioned.

People in England are at the moment inspired to take a COVID-19 check if they’ve not less than one of many 4 traditional signs: lack of sense of style, lack of sense of odor, fever, new persistent cough. This is known as “Pillar 2 testing”.

Based on the brand new REACT study findings, the researchers estimate that present Pillar 2 testing would choose up round half of all symptomatic infections if everybody eligible have been examined. But if the extra signs have been included, this might be improved to three-quarters of symptomatic infections.

The findings, launched as a pre-print report forward of being peer reviewed, are a part of the REACT-1 ongoing stream of research, led by Imperial College London and carried out in partnership with Ipsos MORI. The Real-time Assessment of Community Transmission programme is funded by the federal government’s Department of Health and Social Care.
