The Omicron variant of Covid-19 has spread rapidly around the world since it was first discovered in southern Africa last month, but much is still unknown.
More data is needed to determine its exact properties and how it responds to existing coronavirus vaccines, but the alpha and delta variants encountered during the pandemic process so far.
Omicron has been detected in at least 89 countries so far, and the Netherlands, Germany, South Korea and others have imposed blockades to slow its spread.
According to the UK Health and Safety Agency, the UK has recorded 14 deaths from new variants so far, with more than 60,000 confirmed cases at the time of writing, but Covid’s overall case more than doubled. It soared to a pandemic high of 93,045 last Friday. ..
One thing that has become clear in the last few weeks is how the Omicron variants differ from the original Covid strain.
The World Health Organization estimated that it would take 2 days to 2 weeks for people infected with the first coronavirus strain to develop symptoms, but the Omicron mutant was much faster, close to 3 to 5 days. It is being considered.
“According to a recent analysis by the British Secretary of State, the window between infection and infectivity may be shorter for the Omicron mutant than for the Delta mutant,” said British Health Minister Sajid Javid on December 6. I told MP on the day.
Due to the short incubation period, the time between suspected virus infection and relapse is short, and the chances of a positive test result being recorded are reduced, which spreads very quickly and successfully. I will explain the reason. Time to warn others, enter quarantine, and prevent transmission from spreading.
The short incubation period “makes the virus much more difficult to control,” warned Jennifer Nuzzo, an epidemiologist at the Johns Hopkins Health and Security Center. Atlantic this week.
Another aspect of Omicron, which can be more difficult to detect than other strains, is the three major symptoms we have learned to pay attention to: cough, fever, and loss of taste and smell. It is a little different from the standard index.
In contrast, early warning signs of new variants include itching in the throat, backache, runny nose or stuffy nose, headache, muscle aches and malaise, sneezing, and night sweats.
Current evidence from Omicron cases analyzed in the United Kingdom is that some symptoms such as cough and malaise may last longer, but patients recover on average within 5 days to 1 week. is.
In more severe cases, shortness of breath has also been reported and is expected to continue after 13 days.
Patients with Covid are usually thought to infect others about two days before the first symptoms begin to appear and for about 10 days thereafter.
If you suspect that you have symptoms of Omicron or the still predominant delta mutation, the current NHS advice is to have a PCR test as soon as possible and self-isolate at home to protect others.
At present, our best hope for Omicron is to accept the provision of Vaccine Booster Jab. This will be rolled out to all adults in the UK by the end of December, as studies show that 3 shots are much more likely to be offered. There are only two immunity to the new strain.
However, as Javid told the BBC’s Andrew Marr on Sunday, “there is no guarantee for this pandemic,” so we will adhere to current restrictions, including wearing masks in public spaces, and approach Christmas. And pay close attention.
