COVID-19: Omicron variant

Accelerated studies are carried out to evaluate the transmissibility and severity of the new variant

The World Health Organization reported, on November 26 of the current year, the existence and classification of the variant B.1.1.529 of COVID-19 as worrisome, this was named as Omicron. The foregoing based on the evidence detected days before by South African health authorities.

Some of the knowledge that we have about this variant called Ómicron are the following:

  • Communicability: There are no indications yet, with respect to other variants, that the omicron variant is more transmissible. However, the rapid increase in people testing positive in parts of South Africa has been noted. Epidemiological studies are already being carried out to determine this unknown.
  • Gravity: There is no evidence indicating repercussion or symptomatological difference of the omicron variant. Like any other variant of COVID-19, it could include severe symptoms, including death.
  • Vaccine efficacy: Work is being done quickly to learn about the effects of omicron on current vaccines that prevent the spread of COVID-19. Vaccines effectively prevent severe symptoms and death.
  • Efficiency of current tests: The PCR tests used to detect the virus include the omicron variant. Rapid antigen detection tests are still being analyzed.
  • Studies in progress: The WHO assesses the transmissibility, severity of infection, and efficacy of vaccines, tests, and some treatments.

There is no doubt that continuing with the implementation of a healthy distance, wearing a face mask, getting vaccinated, ventilating the spaces where you stay, and keeping your hands disinfected are recommended measures that prevent the accelerated deployment of this new variant.
