Omicron Covid variant: What symptoms and tests are used to detect Omicron?

On 26 November 2021, WHO assigned the variation B.1.1.529 a variation of concern, named Omicron, on the advice of WHO’s Technical Advisory Group on Virus Evolution (TAG-VE). This choice depended on the proof introduced to the TAG-VE that Omicron has a few transformations that might affect how it acts, for instance, on how effectively it spreads or the seriousness of disease it causes. Here is a rundown of what is right now known. This new variation was first identified in quite a while gathered on November 11, 2021 in Botswana and on November 14, 2021 in South Africa.




How quick is Omicron spreading?

Omicron’s fast rise in South Africa is the thing that worries scientists most, on the grounds that it proposes the variation could start dangerous expansions in COVID-19 cases somewhere else. On 1 December, South Africa recorded 8,561 cases, up from the 3,402 provided details regarding 26 November and a few hundred every day in mid-November, with a significant part of the development happening in Gauteng Province, home to Johannesburg.


What tests are used to detect Omicron?

Swabs from polymerase chain response (PCR) tests, which are shipped off labs for analysis, can show if the variation causing the contamination looks like Omicron, Delta or something different.

Between a third and a portion of UK labs – yet not all – have the necessary innovation to recognize suspected Omicron cases. That implies a few pieces of the nation might analyze more Omicron cases all the more rapidly.

Confirming that a speculated case is Omicron requires a full genetic examination, which can require up to two or three weeks.


How is the Omicron variation identified?

  1. PCR test directed
  2. Test searches for three qualities identifying with parts of the infection: spike (S), nucleocapsid or inner area (N2) and envelope or external shell (E)
  3. Is the S quality identified?

Yes: Unlikely to be Omicron

No: Could be Omicron

  1. Full quality investigation used to affirm test


Do lateral flow tests detect Omicron?

Fast or lateral stream tests (LFTs), which can be utilized at home, can’t let you know which variation you’re infected with – however they are as yet suspected to have the option to let you know if you’re negative or positive, even with Omicron.

In the event that you get a positive LFT result, you have a lawful commitment to self-isolate promptly and should get a PCR test as quickly as time permits to confirm the outcome.


What are the symptoms of Omicron?

Up until this point, in South Africa, the vast majority contaminated are young and their indications have been mild.

There is some idea that the variation could be making some marginally various symptoms Delta – including aching painfulness, and no loss of taste or smell – however it’s too soon to say without a doubt.

Hospitals in South Africa are seeing more people admitted with more genuine symptoms – yet many are unvaccinated or have had just one dose. It will require a couple of more weeks to work out assuming passes are expanding as well.

In the UK, where huge quantities of people are secured with a few portions of a Covid vaccine, a few researchers say Omicron could be a lot milder and have less of an effect.


How might I protect myself and my family against the Omicron variation?

The main thing you can do is reduce your danger of openness to the virus. To ensure yourself and your friends and family, make a point to:

  • Wear a mask that covers your nose and mouth. Ensure that your hands are clean when you put on and remove your mask.
  • Keep an actual distance of no less than 1 meter from others.
  • Stay away from ineffectively ventilated or crowded spaces.
  • Open windows to further develop ventilation indoors.
  • Wash your hands Clean up consistently.
  • At the point when it’s your move, get inoculated. WHO-supported COVID-19 antibodies are protected and powerful.


Study proposes Pfizer vaccine may just to some protect against Omicron

Existing immunizations should in any case ensure individuals who contract the Omicron variation from extreme Covid cases, a World Health Organization (WHO) official says. The Omicron variation of Covid can to some degree sidestep insurance from two doses of immunization made by Pfizer Inc and accomplice BioNTech, Alex Sigal, the exploration top of a South African research center, said on Tuesday. In any case, the review, in light of fundamental information that has not yet been peer-investigated, showed beneficiaries of two antibody dosages who had an earlier disease were generally ready to kill the variation, recommending sponsor portions could help fight off infection.


Dengue- Causes, symptoms and treatment

Dengue- Causes, symptoms and Treatment

Dengue or also known as break bone fever is a mosquito-borne disease that might and might not be severely hazardous for you depending on the severity of symptoms. It is caused due to mosquito bites and leads to a severe flu-illness that can affect any age group.

Dengue outbreaks are quite common in India and are usually on the rise between April’s to November, especially in the northern states.

Since, there is no vaccine present for dengue, the only way to prevent it is by preventing mosquito bites and by reducing the mosquito population. So, people need to be aware of the dengue causes, symptoms and treatment.


Dengue is caused, when an infected female mosquito bites (Aedes aegypti) a healthy person and spreads the virus to the healthy person. There are usually four types of viruses that cause dengue fever and are known to be transferred from Monkeys to humans approx. 100-800 years ago (according to CDC).

Aedes aegypti mosquitoes are usually found in subtropical or tropical regions of the world such as India and can be usually identified by the typical white marking on legs. It usually gets infected when it bites a person with dengue and then spread the virus by biting healthy people.

Since there are four types of dengue viruses, you might get immune to one type after recovering from dengue once but it doesn’t mean you don’t have any danger of dengue in future as you might get infected by the remaining three types. And getting infected by dengue for the second time can cause severe symptoms and side effects on you.


One of the best things that can be done during dengue is getting diagnosed as soon as possible, as it saves you from various severe effects of dengue.

Usually, the symptoms of dengue start appearing after 4-10 days of mosquito bite from an infected mosquito and appear to be quite common. The symptoms of dengue are sometimes so common that people usually mistake them for flu.

So, here are some common symptoms of dengue to help you identify the symptoms and diagnose them on time.

  • High fever around 104 ⁰F along with any of the below symptoms
  • Headache
  • Nausea or vomiting
  • Irritation or pain behind the eyes
  • Muscle, joint or bone point
  • Rashes
  • Inflammation in glands

It usually takes a week to recover from dengue but if you ignore the symptoms in some cases it can lead to severe blood vessels damage leading to leaky vessels and loss of platelets resulting in dengue hemorrhagic fever or dengue shock syndrome. This severe dengue can be really life-threatening for you.

Here are some of the symptoms of dengue hemorrhagic fever that usually occurs 1-2 after the fever stops.

  • Extreme stomach pain and vomiting
  • Fatigue or restlessness
  • Blood in urine, stools or vomit
  • Bleeding through your gums and nose
  • Difficulty in breathing
  • Internal bleeding under the skin that might look like bruises


There is no such specific cure for dengue as it is a virus and usually the treatment is done for the side effects caused by the dengue.

For milder symptoms:

  • When the symptoms are milder the patient is usually advised to remain hydrated by drinking clean water along with rehydration salts to reduce the effects of dehydration caused by the high fever and vomiting.
  • Painkillers and fever-reducing drugs such as Tylenol or paracetamol are also given to reduce symptoms such as pain and fever.

Note that non-steroidal anti-inflammatory drugs (NSAIDs) like aspirin are usually not advised during dengue as they might cause internal bleeding.

For severe cases:

  • Drip or intravenous (IV) fluid supplementation is usually needed in the cases where the person isn’t able to take fluids through the mouth.
  • Patients might need to get admitted to the hospital as the individual needs to be properly monitored by the hospital.
  • Blood transfusion might be needed for people with severe dehydration.

Treatment of Dengue might help you to recover from dengue but nothing is better than preventing it before it can take place. The best way to prevent yourself from dengue is by keeping yourself away from mosquitoes. There are various methods that you can use to stay away from these mosquitoes such as using mosquito repellent, mosquito traps and nets, wearing full clothing and keeping your surroundings clean and away from stagnant water.

These simple steps can be really life and money-saving for you as they will not only help you to stay away from dengue but also save the savings that you might have to spend during the treatment.
