The number of Covid-19 cases in the UK has jumped by more than half a million, with the rise likely due to the latest variants of Omicron BA.4 and BA.5, figures show.
Hospital numbers also continue to rise, with early signs of an increase in ICU admissions among older age groups.
The Office for National Statistics (ONS) estimates that a total of 2.3 million people in private households contracted the virus last week, a 32% increase on the week before.
This is the highest estimate of total infections since late April, but still slightly below the record high of 4.9 million seen at the peak of the Omicron BA.2 wave in late March.
Figures from the ONS show that less than 0.1 per cent of the English population tested positive in the summer of 2020 and 1.57 per cent in 2021. Now it is 3.35 percent.
Now a report from the Covid ZOE analysis program shows that headache has become the most prominent symptom.
The ZOE Covid Study app allows infected people to report their symptoms while exposed to the virus.
The data provided is then analyzed by researchers at King’s College London, who track infections across the UK and identify who is most at risk and where the high-risk areas are.
More than two out of three of all Covid patients who used the app reported suffering from headaches before they tested positive.
Some even suffered from headaches before breathing difficulties.
Professor Tim Spector, head of the Zoe Health Study program, said about it Guardian: “There are definitely a lot of people who had Covid earlier in the year who got it again, including some with BA.4/5 who had BA.1/2 just four months ago and who thought will be protected. .”
Sarah Crofts, ONS head of analytical research for the Covid-19 infection study, said: “In the UK we are seeing a sustained rise of more than half a million infections, likely driven by an increase in BA.4 and BA.5 variants. .
“This growth is seen across all ages, countries and regions of England.
“We will continue to monitor the data closely to see if this increase continues in the coming weeks.”
The virus is still most prevalent in Scotland, where an estimated 288,200 people had Covid-19 last week, or one in 18.
This is a weekly increase of 250,700, or one in 20, and is the highest estimate for Scotland since the start of April. In England, 1.8 million people were likely to have the virus last week, equivalent to about one in 30.
That’s up from 1.4 million, or one in 40, the previous week.
In Wales, infections jumped to 106,000, or one in 30, from 68,500, or one in 45.
Dr Mary Ramsay, director of clinical programs at the UKHSA, said: “We continue to see an increase in Covid-19 data, with increasing cases and hospitalizations in people aged 65 and over, and outbreaks in nursing homes.
“Now we can see an increase in the number of admissions to the intensive care unit in the older age groups.
“Vaccination remains the best protection against serious illness and hospitalization. Covid-19 hasn’t gone away and we all need to be mindful of hand and respiratory hygiene. It is also wise to wear a face mask in crowded indoor spaces.’
