The World Health Organization (WHO) has designated the COVID-19 variant BA.2.86 as a ‘variant under surveillance’ due to the large number of mutations.

The WHO said on Friday that they are currently tracking 3 variants of interest and 7 variants under surveillance.

“WHO continues to call for improved surveillance, sequencing and reporting of #COVID19 as the virus continues to spread and evolve,” WHO said in a tweet.

Who further said that more data is needed to understand this COVID19 variant and the extent of its spread, but the number of mutations needs attention.

Recently, the latest variant, EG.5 (also known as Eris) has attracted the attention of public health experts around the world and is becoming a major strain in countries including the United States and the United Kingdom.

According to the latest estimate from the US Centers for Disease Control and Prevention, CNN, this variant is causing about 17 percent of new COVID-19 cases in the country, compared to 16 percent for the next most common lineage, XBB.1.16. informed of.

The new variant is a spinoff of the XBB recombinant strain of the Omicron family.

According to the WHO, all viruses mutate over time, including SARS-CoV-2, the virus that causes COVID-19. Most of the changes have little or no effect on the properties of the virus. However, some changes may affect the properties of the virus, such as how easily it spreads, the severity of the associated disease, or the performance of vaccines, therapeutic drugs, diagnostic tools, or other public health and social measures.

In June 2020, the WHO Virus Evolution Working Group was established with a specific focus on SARS-CoV-2 variants, their phenotype and their impact on countermeasures. This later became the Technical Advisory Group on SARS-CoV-2 Virus Development. In the late 2020s, the emergence of variants of increasing risk to global public health prompted WHO to prioritize global surveillance and research and to identify some as variants of interest (VOIs) and variants of concern (VoIs) to inform and adjust to COVID-19. VOCs). 19 Feedback. From May 2021, WHO began specifying simple, easy-to-say labels for major variants.

Considerable progress has been made in establishing and strengthening a global system to detect indications of potential VOIs or VOCs and to rapidly assess the risk posed by SARS-CoV-2 variants to public health. It is important that these systems are maintained, and data is shared in accordance with good practices and in a timely manner, as SARS-CoV-2 continues to circulate at high levels around the world. While monitoring the spread of SARS-CoV-2 globally, it is also necessary to monitor their spread in animal populations and chronically infected individuals, to minimize the occurrence of mutations that could negatively impact public health. There are important aspects of global strategy.

In March 2023, WHO updated its tracking system and working definitions for variants of concern, variants of interest and variants under surveillance, according to WHO.
