The new variant B 1.1. 529, which was designated as a ‘Variant of Concern’ by World Health Organisation on Friday night, has been assigned the name Omicron. Reported by public health officials of South Africa, the new variant has triggered a lot of concern worldwide over a probable resurgence of Covid infections. While many new variants of SARS-CoV-2 were reported in the last few months, the B1.1.529 or Omicron unfortunately has attracted lot of interest.
Here are the most important questions related to the new variant that one must pay attention to: –
So far, Covid infections due to Omicron variant have been reported in South Africa (77 cases), Botswana (4 cases), Hong Kong (2 cases) and 1 each in Belgium and Israel.

The new variant B 1.1.529 appears to be faster than the existing dominant Delta variant. For instance, in less than 2 weeks, it has become a dominant variant of all infections in South Africa, out-competing the Delta variant. The Delta variant was already devastating in South Africa.
Everything we know so far on the new B.1.1.529 variant, for which there is an emergency @WHO meeting to reviewhttps://t.co/TmxGBi6IEv @nature by @ewencallaway @naturehttps://t.co/r9kHwg2zjWhttps://t.co/tBEct7F8M7 🧵by @jburnmurdoch @FT pic.twitter.com/fe5pkIpqnW

Reports have indicated that many persons who tested positive for B 1.1.529 in South Africa and other countries were fully vaccinated and some even had received booster doses. Scientists are worried that the new variant might bypass the current vaccines against Covid-19. The B.1.1.529 variant has 50 mutations overall, including more than 30 on the spike protein alone which is the target of most current Covid vaccines. However, a clearer picture will emerge in the coming days, as researchers don’t yet know the clear implications of the new variant on vaccines and boosters.
According to MOHFW, the new variant is reported to have a significantly high number of mutations, and thus has serious public health implications.
The B1.1.529 has more than 2 times the number of bad spike mutations than the Delta variant. The new variant has an extremely high 32 worrisome mutations in the spike protein, which is a real concern than the Delta variant.
Every few months, we hear about anew variant

Most turn out to not be much
Well, unfortunately, there's a new variant B.1.1.529 that is concerning
What do we know so far? A few things but not a lot
Reminder: when it comes to variants, we focus on three things
Short thread
Based on reports from South Africa, the B1.1.529 has become the dominant strain. It appears to be faster than the existing dominant Delta variant. For instance, in less than 2 weeks, it has become a dominant variant of all infections in South Africa
Countries like United Kingdom has imposed travel restrictions on African countries over concerns that vaccines may be less effective against the variant. Germany, Italy, Israel, Japan, Kenya and Singapore have also restricted travel. The European Union has called its member states to halt travel to and from nations where the new variant has been reported.
Concerned with the development of new variants, the Ministry of Health and Family Welfare (MOHFW) has directed Indian States to strengthen surveillance activities across all airports. States have started tracking travellers flying-in from countries where the infections due to the new variant have been reported.
Following the detection of the new variant, the WHO technical advisory group on SARS-CoV-2 virus evolution is expected to meet to review what’s known and plan further studies. Meanwhile, we need to focus on strengthening vaccination coverage and public health measures. Let’s be cautious, listen to scientists & not panic, WHO, Chief Scientist, Soumya Swaminathan said.

Infectious Disease Epidemiologist; COVID-19 Technical Lead at WHO, Maria Van Kerkhove urged everyone out there not to discriminate against countries that share their findings on new variants openly. I thank researchers from South Africa and Botswana for sharing information with WHO and world about B.1.1.529 variant that has been recently detected. We will convene our TAG-VE again today to discuss the issue.
