British scientists have identified changes in the main “Govit-19” symptoms over time, dominated by the “alpha” strain last year, and now taken into account the “delta” strain.

The study also found that the results included more than five million PCR tests in the UK between April 26, 2020 and August 7, 2021, of which 28,000 (0.67 per cent) were positive.

In the UK, four main symptoms are used to diagnose Govt-19: loss of taste and smell, fever and dry cough. The symptoms listed in the CDC protocols are high, and include fever, chills, cough, shortness of breath, loss of sense of smell and taste, fatigue, muscle aches, headache, sore throat, nasal congestion, runny nose, nausea, vomiting and diarrhea.

Scientists: Discovering a new variable

The results of the study show that between April and December 2020, the British “alpha” strain dominated the UK, and the most common symptoms were sore throat, cough, fever, loss of taste and smell.

But after May 2021, the Indian “delta” strain dominated, leading to the addition of new symptoms to four “traditional” symptoms, including severe headaches, so that some of those vaccinated against the disease complained of headaches and sore throats. Half of those affected by “delta” strain complained of muscle pain, weakness and fatigue, and a third of them lost their sense of smell and taste.

Interestingly, these symptoms appeared in young people in their 20s and 30s, disappearing in the elderly and appearing in a small percentage of the elderly. Added to the main symptoms of “Govit-19” in the winter of 2020-2021 are symptoms of other viral respiratory diseases, as well as symptoms of intestinal diseases associated with seasonal microbes.
