The UK Health Security Agency (UKHSA) has compared symptoms of infection to Variants of the omicron . coronavirus (B 1.1.1.529) and delta (B.1.617.2) from Wednesday December 1 to Tuesday December 28, 2021. With this data provided by people who tested positive for PCR, our knowledge of COVID-19 has been updated once again.
according to him study, based on 182,133 cases of omicron and 87,920 cases of delta detailing symptoms with their onset in the said period. They announced their age, gender, and region.
the throat pain The flag was most frequently reported by omicron with a frequency of approximately 2 to 1 (1.93) with respect to the delta version of the coronavirus.

Similarly, such symptoms were identified in 53% of omicron infections, while in the variant documented for the first time in India -October 2020- it reached 34%.
Meanwhile, cough and fever were more common with Omicron than with Delta.
On the other hand, loss of smell (loss of smell) and taste (senescence) were found to be less common in the selected variant in South Africa (13%) than in deltas (34%).

Symptoms reported with similar frequency in both SARS-CoV-2 were diarrhea, muscle aches, nausea, vomiting, rash, fatigue, headache, and confusion.

Another recent study led by the University of Oxford and the National Statistics Office reviewed the markers that distinguish between positive and negative people in PCR.
“With omicron cases increasing as a proportion of SARS-CoV-2 infections through December 2021, The study found an increase in reports of sore throats and a significant decrease in reports of loss of smell and taste in PCR positives.‘, the researchers emphasized.
They also found that differences between variables in symptom frequency occurred regardless of vaccination status (unvaccinated, immunized, or booster).

It also found that sore throats became common in cases with negative symptoms, so its presence does not specifically predict omicron infection, which the World Health Organization classified as a variable of concern on November 26, 2021. This may be related to seasonal illnesses that are not closely related to COVID-19.
Marker data, as discussed in the Limitations section, was recorded three to four days after onset. “Therefore, additional symptoms that occur later are not recognized,” he said.
