There may be international concern and widespread alarm on the discovery of SARS-CoV-2 variant B.1.1.529, which the World Well being Group (WHO) has referred to as Omicron.
The WHO has categorized Omicron as a “variant of concern” as a result of it has a variety of mutations. This means vaccines and coverings might be much less efficient.
Though early days, Omicron seems to have the ability to reinfect folks extra simply than different strains.
Australia has adopted different international locations and areas – together with the US, Canada, United Kingdom and the European Union – and banned travellers from 9 southern African international locations.

Omicron is the brand new COVID child on the block: 5 steps to keep away from, ten to take instantly
Australians looking for to return dwelling from southern Africa will nonetheless give you the chance to take action. However they must enter resort quarantine and be examined, as will those that have returned from the 9 stipulated international locations – South Africa, Namibia, Zimbabwe, Botswana, Lesotho, Eswatini, the Seychelles, Malawi and Mozambique – previously 14 days.
However Omicron has already been detected in different areas, together with the UK, Germany, Israel, Hong Kong and Belgium. So whereas a journey ban on southern African international locations could gradual the unfold and purchase restricted time, it’s unlikely to cease it.
Because the Australian authorities and others act to guard their very own residents, this ought to be accompanied by extra sources to help international locations in southern Africa and elsewhere that take immediate motion.
When was Omicron detected?
The variant was recognized on November 22 in South Africa, from a pattern collected from a affected person on November 9.
South African virologists took immediate motion, conferred with colleagues by way of the Community of Genomic Surveillance in South Africa, liaised with authorities, and notified the World Well being Group on November 24.
That is in line with the Worldwide Well being Rules that information how international locations ought to reply.
The behaviour of this new variant continues to be unclear. Some have claimed the speed of development of Omicron infections, which displays its transmissibility, could also be even greater than these of the Delta variant. This “development benefit” is but to be confirmed however is regarding.
‘Kneejerk’ response vs WHO suggestions
African scientists and politicians have been disillusioned in what they see as a “kneejerk” response from international locations imposing journey bans. They argue the ban may have important detrimental results for the South African economic system, which historically welcomes international vacationers over the summer season year-end interval.
They notice it’s nonetheless unclear whether or not the brand new variant originated in South Africa, even when it was first recognized there. As Omicron has already been detected in a number of different international locations, it could already be circulating in areas not included within the journey ban.
Journey bans on international locations detecting new variants, and the next financial prices, might also act as a disincentive for international locations to disclose variants of concern in future.
The WHO doesn’t typically suggest flight bans or different types of journey embargoes. As a substitute, it argues interventions of confirmed worth ought to be prioritised: vaccination, hand hygiene, bodily distancing, well-fitted masks, and good air flow.
In response to variants of concern, the WHO calls on all international locations to boost surveillance and sequencing, report preliminary instances or clusters, and undertake investigations to enhance understanding of the variant’s behaviour.
Omicron should be taken significantly. Its options are worrying, however there are massive gaps in our present data. Whereas additional analyses are undertaken, the variant ought to be managed with testing, tracing, isolation, making use of identified public well being measures, and ongoing surveillance.
What can wealthier international locations do to assist?
Rich international locations comparable to Australia ought to help African nations and others to share early alerts of doubtless critical communicable illness threats, and assist mitigate these threats.
Because the Unbiased Panel for Pandemic Preparedness and Response famous in Might:
[…] public well being actors solely see downsides from drawing consideration to an outbreak that has the potential to unfold.
The panel beneficial creating incentives to reward early response motion. This might embrace help to:
set up analysis and academic partnerships
strengthen well being methods and communicable illness surveillance
tremendously enhance vaccine availability, distribution, and fairness
take into account monetary compensation, by way of some type of solidarity fund in opposition to pandemic danger.
Boosting vaccine protection is vital
Vaccines stay the mainstay of safety in opposition to probably the most extreme results of COVID-19.
It’s unclear how efficient vaccines shall be in opposition to Omicron, however some extent of safety is presumed possible. Pfizer has additionally indicated it may develop an efficient vaccine in opposition to a brand new variant comparable to Omicron inside 100 days or so.
COVID’s persistence is partly attributable to patchy immunisation protection throughout many components of the world, notably these least developed. South Africa itself is healthier off than most international locations on the continent, but solely 24% of the grownup inhabitants are presently absolutely vaccinated. For the entire of Africa, this drops to solely 7.2%.
Higher international help is urgently wanted to spice up these vaccination charges.

African establishments and leaders, supported by international well being and vaccine specialists, have argued for mRNA vaccine manufacturing amenities on the African continent. These would prioritise regional populations, overcome supply-chain issues, and reply in actual time to rising illness threats.
But creating nations face important obstacles to acquiring mental property round COVID-19 vaccine improvement and manufacturing.
Whereas there may be nonetheless a lot to study concerning the behaviour and influence of Omicron, the worldwide group should show and commit actual help to international locations that do the appropriate factor by promptly and transparently sharing info.
