Experts of WHO have cautioned that the next Covid-19 variation would be more transmissible, and maybe more lethal, than its predecessors, even as the globe returns to normalcy with the Omicron wave diminishing.
Dr Maria Van Kerkhove, WHO epidemiology and technical lead on Covid-19, stated at a recent press conference that
the pandemic is far from finished and that subsequent varieties would be more aggressive than Omicron is currently.
The next variation
“The next variation of worry will be more fit, which means it will be more transmissible since it will have to outperform what is now circulating.”
She also cautioned that the next version might elude immunity more quickly, making vaccinations less effective. She emphasised the importance of taking the vaccine since it protects against serious sickness and death, as demonstrated during the Omicron wave.
Dr. Van Warned
“We anticipate that the circulation of Covid-19 will be minimal with the correct actions.” “However, even within those readerships, there will be arc among those who haven’t been vaccinated or whose immunity is fading,” Dr Van Kerkhove warned.
The WHO has classified the Delta variation, which was initially discovered in India in October 2020, as a variant of concern.
The Delta version spread 50% quicker than the Alpha variant, which was 50% more infectious than the initial strain of SARS-CoV-2, also known as the coronavirus.Six months later, the Delta strain had rushed to the country, killing lives and producing a record-breaking number of daily cases.
By June 2021, it has caused a new wave of cases in the United Kingdom, Israel, Russia, Australia, and a number of other countries.
The Previous variant
After being discovered in late November 2021 in South Africa, Omicron was swiftly labelled as a variety of concern. In a much shorter time, Omicron has superseded Delta as the prevalent strain.
Omicron is at least two to four times more transmissible than Delta, although being milder. It also has a five-fold higher risk of reinfection than Delta, as well as an improved capacity to avoid vaccinations.
