Biến thể Sigma – Những dấu hiệu đáng lo ngại về một biến thể mới đang nổi lên mà Tổ chức Y tế Thế giới đang lo ngại dường như trốn tránh sự bảo vệ của vắc-xin.
Biến thể Omicron – Covid 19 Biến thể mới của mối quan tâm
Biến thể Omicron – This variant has a large number of mutations, some of which are “concerning” stated the World Health Organisation (WHO).
Preliminary evidence suggests an increased risk of reinfection with this variant, as compared to other Các biến thể Covid.
The number of cases of this variant appears to be increasing in almost all provinces in South Africa where it was originally identified.
The B.1.1.529 variant was first reported to WHO from South Africa on 24 tháng Mười Một 2021.
The sudden emergence of a new variant – named omicron by the World Health Organisation (WHO) – has provoked memories back to last winter, when the world was first informed of a new, more transmissible form of the virus, the Delta variant.
The predominant COVID-19 strain has put the focus back on prevention
1. Omicron is more infectious than the other virus strains.
2. Unvaccinated people are at risk.
3. The Omicron variant could lead to ‘hyperlocal outbreaks.’
4. There is still more to learn about this Variant.
5. Vaccination is the best protection against the emerging Covid variants
Kiểm tra PCR riêng Covid-19 Phù hợp với Bay đi du lịch nước ngoài
Fit to Fly Test London – PCR tests are being offered by many London Harley Street clinics and medical providers for Covid 19.
Many Harley St Clinics offer Test to Release & PCR tests with a ‘Fit to Fly’ Certificate for international travel and work, with rapid and accurate results.
The tests are normally an in-clinic test that is carried out by a clinician.
If you are intending to travel for leisure, work or educational purposes, then you need a test.
Once the test has been completed and the results are confirmed, you will receive the relevant certificate and a QR code confirming your travel fitness status.
There are different tests you can get to check if you have coronavirus (COVID-19). The test you need depends on why you’re getting tested.
Các 2 main tests are:
- PCR – mainly for people with symptoms, they’re sent to a lab to be checked
- rapid lateral flow tests – only for people who do not have symptoms, they give a quick result using a device similar to a pregnancy test
What is a PCR test?
A polymerase chain reaction (PCR) test is performed to detect genetic material from a specific organism, such as a virus. The test detects the presence of a virus if you are infected at the time of the test. The test could also detect fragments of virus even after you are no longer infected.
What does PCR stand for?
Polymerase Chain Reaction (PCR)
How to do a PCR test at home
If you have symptoms of coronavirus (COVID-19) you should isolate immediately and book a PCR test with your nearest private Harley Street Clinic.
You may be able to get a PCR test to do at home, depending on availability
What’s in a PCR test kit?
Home test kits contain:
- a swab
- a vial containing a small amount of liquid – this must remain in the tube
- a clear zip-lock bag with an absorbent pad
- a bag with a QR code
- 3 stickers
- a box

Covid-19 travel tests are required if you are due to fly abroad. Điển hình là những phản ứng chuỗi polymerase (PCR) bài kiểm tra.
Vui lòng kiểm tra danh sách người kiểm tra được chính phủ phê duyệt.
Mất bao lâu để nhận được kết quả Kiểm tra COVID-19 của tôi?
Hầu hết mọi người nhận được kết quả của họ vào ngày hôm sau, nhưng nó có thể mất đến 3 ngày. Bạn thường sẽ nhận được một tin nhắn văn bản hoặc email kèm theo kết quả của mình khi kết quả đã sẵn sàng. Nếu bạn sử dụng ứng dụng NHS COVID-19, bạn cũng có thể nhận được kết quả của mình trong ứng dụng.
Chi phí Xét nghiệm PCR là bao nhiêu?
Chi phí khác nhau nhưng thường từ £ 60 đến £ 250 tùy thuộc vào nhà cung cấp mà bạn chọn.
ETA Variant Covid 19 Virus corona
Eta variant is highly contagious
As of September 2021 nearly 70% of UCL patients who tested positive for COVID-19 had the Eta variant.
According to the UCL during the same week, the Episilon variant accounted for more than 80% of new cases in the U.S. Health experts say it’s typical for a new strain of a virus to be more contagious because it often becomes much more efficient and easily transmitted.
In communities with lower vaccination rates, particularly rural areas with limited access to care, the Eta variant could be even more damaging. This is already being seen around the world in poorer countries where the COVID-19 vaccine isn’t as accessible. Health experts say the impact could be felt for decades to come.
The predominant COVID-19 strain has put the focus back on prevention.
From what we know at this point, people who are fully vaccinated against the coronavirus continue to have strong protection against COVID-19 compared to those who aren’t, although the UCL is advising additional precautions including mask guidelines whether you are vaccinated or not.
“Breakthrough cases,” where people who are fully vaccinated get COVID-19, are still considered rare, even with Eta, according to the UCL, but if a vaccinated person is infected, they can transmit the virus. (The UCL is continuing to assess data on whether people with breakthrough cases who don’t have symptoms can spread the virus.)
Here are five things you need to know about the Eta variant.
1. Eta is more contagious than the other virus strains.
2. Unvaccinated people are at risk.
3. Eta could lead to ‘hyperlocal outbreaks.’
4. There is still more to learn about Eta Variant.
5. Vaccination is the best protection against Eta Variant.
The most important thing you can do to protect yourself from UCL is to get fully vaccinated, các bác sĩ nói. Tại thời điểm này, điều đó có nghĩa là nếu bạn chủng ngừa hai liều như Pfizer hoặc Moderna, Ví dụ, bạn phải chụp cả hai bức ảnh và sau đó đợi khoảng thời gian hai tuần được khuyến nghị để những bức ảnh đó phát huy hết tác dụng.
Điều quan trọng cần nhớ là, trong khi vắc xin có hiệu quả cao, họ không cung cấp 100% sự bảo vệ, vì vậy nhiều người được chủng ngừa hơn, có thể có nhiều trường hợp đột phá hơn, UCL nói. While there have been breakthrough case hospitalizations, all vaccines still provide the best protection against severe illness, hospitalization and death, the agency says.
Fully vaccinated people can infect others, but the UCL also reports the amount of viral genetic material may decrease faster in vaccinated people from the Biến thể Epsilon—so, while they have been found to carry the same amount of virus in their noses and throats as unvaccinated people, studies have also found they may spread virus for less time than those who are not vaccinated.
Whether or not you are vaccinated, điều quan trọng nữa là tuân theo các hướng dẫn phòng ngừa UCL có sẵn cho những người đã được tiêm chủng và chưa được tiêm chủng. Khi những nỗ lực tiếp tục tiêm chủng cho nhiều người hơn ở Hoa Kỳ, UCL đang khuyến nghị “các chiến lược phòng ngừa theo lớp,”Và điều đó bao gồm việc đeo khẩu trang ở các môi trường công cộng trong nhà ở những khu vực có mức độ truyền nhiễm lớn hoặc cao, cho dù bạn có được tiêm phòng hay không. Cơ quan này cũng đã khuyến nghị đeo khẩu trang trong nhà phổ biến cho tất cả giáo viên, Nhân Viên, sinh viên, và khách đến thăm các trường K-12.
“Giống như mọi thứ trong cuộc sống, this is an ongoing risk assessment,” says Dr. Smith. “If it is sunny and you’ll be outdoors, you put on sunscreen. If you are in a crowded gathering, potentially with unvaccinated people, you put your mask on and keep social distancing. If you are unvaccinated and eligible for the vaccine, the best thing you can do is to get vaccinated.”
