Covid symptoms for Omicron, Deltacron and ‘Stealth Omicron’

Across the UK, the number of Covid-19 infections continues to rise, with infection rates once again rising.

In the three weeks since 24 February, the infection rate has more than doubled – rising from slightly below 39,000 to over 93,000 on 16 March. Cases are on the rise in Wales, England, Scotland and Northern Ireland. .

This surprising escalation has largely been on the horizon, with news elsewhere dominating the headlines.

The spike in cases coincides with a relaxation of the general Covid rules across the union and what will likely be a fade in vaccine protections, as at a time when most countries All have used booster shots.

But it’s not just these two factors that scientists believe are causing the numbers to rise again – it’s also thought that new variants and sub-variants also play a part.

The situation has raised some uncertainty as to whether symptoms and spread vary between strains – so read on for details on what to watch out for in terms of variables. The main body is currently raging across the UK.

What are the standard symptoms of Covid-19?

According to NHSThe main symptoms of Covid-19 are:

  • High temperature – this means you feel hot to the touch of your chest or back (you don’t need to take the temperature).
  • A new, ongoing cough – means three or more coughs in 24 hours (if you have frequent coughs, the cough may be worse than usual).
  • Loss or change in smell or taste – this means you have noticed that you cannot smell or taste anything, or that everything smells or tastes different than usual.

It is thought that most people infected with the virus will develop one of these manifestations.

What are the symptoms of Omicron (BA.1)?

Omicron raged across the UK over Christmas and into the new year, causing a spike in the number of cases.

It continues to be the most dominant virus strain globally to date, accounting for 98.8% of all Covid cases submitted to the GISAID global database for virus tracking since May 25. first.

This strain infects people’s upper respiratory tract at an extremely high rate – 70 times faster than the Delta variant that formerly dominated.

Five of the most common symptoms of this variant are:

  • snivel
  • headache
  • weariness
  • sneezing
  • sore throat

Sanjaya Senanayake, associate professor of medicine and infectious disease physician at the Australian National University, said the Omicron variant was more likely to cause a sore throat than Delta but was less likely to cause loss of taste or smell.

For children, it is more likely to produce a cough known as croup. Often combined with other viruses, Omicron’s upper respiratory tract infection makes it more likely.

Omicron continues to spy on the UK, threatening vulnerable people. On March 16, 153 people died after contracting the coronavirus.

On March 7, the World Health Organization issued an announcement: “As we enter the third year of the pandemic, SARS-CoV-2, the virus that causes Covid-19, is spreading between people and global intensity.

“There are a lot of factors that are driving momentum. One of them is the emergence of highly transmissible variants of interest, the latest being Omicron. The virus continues to evolve and the risk of future variants appearing is very high. “

What are the symptoms of Stealth Omicron (BA.2)?

According to the UK Health Security Agency (UKHSA), the sub-variant known as ‘Stealth Omicron’ was discovered last December and is being treated as an “under investigation”.

Chief Executive Officer, Dr Jenny Harries said: “The increasing presence of Omicron’s BA.2 sub-lineage and the recent slight increase in the number of infections among people over 55 years of age suggest that the pandemic is still present. It’s not over yet and we can expect to see Covid circulating at high levels.”

Data collected by the Wellcome Sanger Institute shows that in the last week of February 2022, the BA.2 variant accounted for 57% of new cases in the UK – meaning that in terms of transmission it is currently the dominant variant in the UK. There are concerns that Stealth Omicron could be even more toxic than its predecessor.

Former WHO epidemiology professor Adrian Esterman took to Twitter to post the warning.

“Omicron BA.2 is about 1.4 times more infectious than BA.1. The basic reproduction number (R0) for BA.1 is about 8.2, making the R0 for BA.2 about 12. This makes it pretty close to measles. The infectious disease that we know of.”

Research from Denmark shows that, in the early stages, this variant poses only a limited threat to human life and does not cause serious symptoms.

It chose the ‘stealth’ part of its name out of concern that it might be harder to track, the lack of an Omicron gene that could make detecting the virus easier.

At present, it is not known whether the sub-strain has different symptoms, although indication reports submitted to the ZOE Covid app show symptoms including runny nose, headache, sore throat and tired.

Other common Covid indicators include sneezing, persistent cough, hoarseness, chills or shivers, unusual joint pain, fever, dizziness, brain fog, eye pain, altered sense of smell, muscle pain , swollen glands, loss of appetite and chest pain.

Covid-19 incident director at UKHSA, Dr Meera Chand, said: “The nature of viruses is to evolve and mutate, so we may continue to see new variants emerge as pandemic continues. Surveillance allows us to detect them and assess if they are significant.

“To date, there has not been sufficient evidence to determine whether BA.2 causes more severe disease than Omicron BA.1, but data are limited and UKHSA continues to investigate.

“Case rates remain high across the UK and we must stay vigilant and get vaccinated. We should all continue to check in regularly with LFDs. [lateral flow tests] and do a PCR test if symptoms develop. “

What are the symptoms of Deltacron?

Having first bred its ugly head in January, this Frankenstein cross was selected in the United States and early research indicates it was the product of a person infected with both the Omicron and Delta variants of the same species. a time.

The variants are thought to be predominantly Delta, but with the addition of an Omicron-derived mutant protein.

Very few cases have been reported to date.

National director for health screening and protection services at Public Health Wales, Dr Meng Khaw, said WalesOnline : “There is no evidence of vaccine avoidance problems associated with Deltacron, and the best thing you can do to protect yourself against this and other variants is to take up the coronavirus vaccine offer.

“You can also protect yourself and others by maintaining social distancing if possible, washing your hands often, keeping your home well-ventilated, using face coverings and working from home if possible.

“If you have a cough, fever, or change in taste or smell, public health advice is that you should self-isolate immediately to protect others.”

This variant is not thought to have different symptoms from previous forms of the virus.
