A Omicron continues to spread rapidly around the world and is already the cause of Covid-19, at least in 38 countries…
Last option of concern (VdP) SARS-CoV-2 it was first discovered in South Africa and after about two weeks had already spread beyond Africa to Asia, Europe and America.
Despite mild symptoms, this VdP causes fear due to rapid spread and as we are on the cusp of the Christmas season, the governments close borders contain outbreaks causing flight cancellations and stricter restrictions around the world.
Since many of those infected with this new variant are asymptomatic, which main symptoms generated by Ómicron:
- Fatigue;
- Slight irritation in the throat;
- Headache;
- mild fever;
Several patients who were prescribed Omicron in South Africa experienced high fever, intermittent cough, and loss of taste or smell. The most severe symptoms are most often seen in people who have not been vaccinated against Covid-19.
Who else no records of any deaths refers to the Omicron variant.
Opening
Option titled B.1.1.529 was discovered by the investigator Rachel Viana November 19 from a sample taken ten days earlier reported to the World Health Organization (WHO) November 24.
Two days later, it was designated as “Option of concern(VdP) mainly due to the confirmed rapid spread and the many mutations found. This list has been renamed to Omicron…
Group Technical advice on the evolution of the SARS-CoV-2 virus WHO (TAG-VE, an abbreviation for English), which brings together the network of WHO reference laboratories for the study of Covid-19, is intensively investigating the new variant, finding a series of mutations, including in the S-protein. or “Thorn“(Spicula), responsible for cell infection.
Researchers from all over the world are also studying Omicronin terms of transmission, severity of infections and confirmed symptoms, response to vaccines, diagnostic tests, and ongoing treatment.
Conclusions are still few, I guess great ability to re-infection who already had Covid-19 than previous options, but according to WHO, do not justify blocking travel.
UN Secretary General, Antonio Guterres, he even mentioned that “travel apartheid“against some African countries, primarily against the one that determined Omicron and who shared the data with the rest of the world.
WHO encourages countries to share data on their hospitalized “coronavirus patients” to accelerate the study of Omicron, and encourages citizens basic infection control measures:
-
social distance of at least one meter;
-
use of permitted masks;
-
regular ventilation of enclosed spaces;
-
avoid crowded places;
-
wash your hands regularly;
-
coughing or sneezing, hiding behind an elbow or handkerchief;
-
get yourself vaccinated as soon as possible.
Preliminary evidence suggests an increased risk of re-infection compared to VdP previous events, but there is still no unequivocal conclusion about this threat. Vaccines are still considered effective and Omicron is detected by PCR tests.
It is unclear if the new variant causes more serious illness than the previous ones, including Delta. Preliminary data only show an increase in hospital admissions, especially in South Africa.
Two years SARS-CoV-2
For about two years, we have been living around the world with the SARS-CoV-2 virus, which is the cause of Covid-19. During this time, this latest member of the coronavirus family has infected more than 263 million people around the planet with at least five VdPs.
In each infected organism, copies are made and multiplied, allowing the virus to adapt and evolve from the original that caused the pandemic.
Since at least September 2020, there are options that worry health experts because they may be more resistant or cause a more severe form of Covid-19.
But what exactly are the variants of the Covid-19 virus?
Viruses, as a rule, start by infecting the host and then replicate, that is, make copies of themselves.
Most viruses consist of RNAGenetic material, for example, is more unstable than DNA. This characteristic increases the likelihood that it will undergo changes over time, slightly altering the corresponding genetic sequence.
Sequence changes are known as genetic mutations. Viruses with mutations are called strains or variants…
Some mutations may not alter the properties of the virus, others may even be harmful to the viruses themselves, but some may ultimately confer a “selective advantage” and even make the virus more “friendly” to the host and render it benign. …
In the case of SARS-CoV-2, the virus that causes Covid-19, WHO has classified as Variants of Concern (VdP) those viruses that have the potential to cause serious infections or spread more easily. Under close supervision. …
