Moscow: Russia recorded 23,888 new Covid-19 cases in the last 24 hours, up from 22,430 the day before, bringing the cumulative total to 7,511,026, the federal response centre said on Thursday.
This is the highest single-day increase since July 25, when the country confirmed 24,072 new cases.
“Over the past day, 23,888 Covid-19 cases were confirmed across 85 Russian regions, including 2,020 cases (8.5 per cent) without clinical symptoms,” the centre said, adding that the rate of increase grew to 0.32%.
Moscow has the highest number of new cases with 3,998 daily infections, up from 3,004 the day before. The Russian capital is followed by St. Petersburg with 2,077 cases, up from 1,933, and the Moscow region with 1,216 cases, down from 1,223.
The response centre reported a new record of 867 deaths linked to the coronavirus, up from 857 the day before, bringing the country’s death toll to 207,255.
In the same 24 hours, 18,826 Covid-19 patients were discharged from hospitals across the country, up from 18,456 the day before, bringing the total to 6,672,767.
Meanwhile a study says over 35 per cent of people had at least one long-Covid symptom diagnosed in the 3-6 month period after Covid-19 infection.
According to researchers, including Paul Harrison from the University of Oxford, the most common symptoms were breathing problems, abdominal symptoms, fatigue, pain and anxiety/ depression.
Research of different kinds is urgently needed to understand why not everyone recovers rapidly and fully from Covid-19. We need to identify the mechanisms underlying the diverse symptoms that can affect survivors, Harrison, who headed the study, said in a statement.
For the study, the team investigated long-Covid in over 2,70,000 people recovering from Covid-19 infection, using data from the US-based TriNetX electronic health record network.
The study reported on how commonly nine core long-Covid symptoms were diagnosed and how this rate compared to people recovering from influenza.
The nine core long-Covid symptoms, occurring 90-180 days after Covid-19 was diagnosed, comprise — abnormal breathing – 8 per cent, abdominal symptoms – 8 per cent, anxiety/depression – 15 per cent, chest/throat pain – 6 per cent, cognitive problems (‘brain fog’) – 4 per cent, fatigue – 6 per cent, headache – 5 per cent, myalgia (muscle pain) – 1.5 per cent, other pain – 7 per cent, any of the above features – 37 per cent.
Higher rates were seen if the whole 1-180 day period after Covid-19 infection was included.
The severity of infection, age, and sex affected the likelihood of long-Covid symptoms: long-Covid symptoms were more frequent in those who had been hospitalised, and they were slightly more common in women.
These factors also influenced which of the symptoms people were most likely to experience. For example, older people and men had more breathing difficulties and cognitive problems, whereas young people and women had more headaches, abdominal symptoms and anxiety/depression.
Many patients had more than one long-Covid symptom, and symptoms tended to co-occur more as time progressed.
The study also looked at the same symptoms in people recovering from influenza. Long-Covid symptoms did occur after influenza, but were 1.5 times more common after Covid-19.
