Do you still need to isolate if you have covid? How long are you infectious?

Access to UK hospitals for patients COVID-19 prompting experts to warn that Britain is in the middle of nowhere The fifth wave from coronavirus infections caused by BA.4 and BA.5 sub-options from Omicron.

Life has largely returned to normal since the final social distancing restrictions were lifted on February 24, with masks, distancing and hand sanitizer largely forgotten by most as the national focus shifted. Partygatethe war Ukraine and cost of living crisis.

But the country saw a 43 per cent rise in cases in early June, which appears to have been driven by crowds flocking to celebrate the Queen’s platinum jubilee over a four-day weekend.

The latest figures show 1.7 million people have tested positive in the UK, a 23 per cent increase in one week (wow).

Even more troubling, hospitalizations are up 31 percent, higher than Omicron’s last revival in March.

Health chiefs have warned that the new outbreak will have a significant impact NHS It is “already on its knees” and expressed concern over the return of major live events such as Glastonbury, Notting Hill Carnival and Edinburgh Festival, which could become super-spreader venues if precautions are not taken.

The last significant increase in cases was in December and January, driven by Omicron, which spread rapidly around the world after it was discovered in South Africa in late November, once again threatening the Christmas holidays and prompting the launch of booster vaccines.

Omicron proved less severe but more contagious than its predecessors, the Alpha and Delta variants, with the total daily number of cases in England reaching a pandemic high of 218,724 on January 4, according to the UK Health Safety Agency, before gradually falling.

Since then, only people over the age of 75 have been offered second booster interventions, meaning that immunity can decline and lead to Asking for a quote for a new amplifier more broadly this fall.

“If we’re going to go into another wave, maybe that’s something that needs to be reviewed,” said John Roberts, one of the lead analysts at the Covid Actuaries group.

What public health officials had to learn last winter when Omicron arrived was how this variant differed from the original Covid strain.

since World Health Organization Estimating that it took two days to two weeks for people infected with the first coronavirus strain to develop symptoms, Omicron has proven that incubation occurs much faster, at three to five days.

“Recent analysis by the UK Health Safety Agency suggests that the window between infection and infection may be shorter for the Omicron variant than for the Delta variant,” the UK health minister said. Sajid Javid He announced this in the House of Commons on December 6.

This explains why the strain was able to spread so quickly and successfully because its short incubation period gave victims a short window between suspecting the virus and a flare-up, which is unlikely to result from a positive side-stream test. It was recorded in time to warn others, enter isolation and prevent transmission of infection.

Shorter incubation period “It makes the virus much, much, much harder to control”Jennifer Nuzzo, an epidemiologist at the Johns Hopkins Center for Health Security, observed Atlantic in the same month.

Another feature of Omicron that potentially made it more difficult to detect than earlier strains was that its symptoms differed somewhat from the three main indicators we were warning about in 2020: cough, fever, and loss of taste. the smell

Early warning signs of the latest variant, by contrast, included a scratchy throat, lower back pain, runny or stuffy nose, headaches, muscle aches and fatigue, sneezing and night sweats.

Cases analyzed by Omicron in Britain found that patients usually recovered in an average of five days to a week, although some symptoms, such as cough and fatigue, were likely to last longer.

The shortness of breath experienced by some sufferers has often been reported to last up to 13 days after other symptoms have subsided.

Covid patients are usually thought to be infectious to others about two days before and about 10 days after their first symptoms appear.

If you think you have symptoms related to the coronavirus, Current NHS advice is to perform a lateral flow test and isolate at home for five days if the test is positive to prevent transmission to others (for 10 days you must stay away from anyone who is particularly vulnerable due to their age or pre-existing conditions. ).

If you must go out in public, we recommend wearing a face mask, avoiding crowded indoor spaces, and washing your hands for at least 20 seconds.
