DenpaNews The COVID-19 in United States and several other countries is improving, but we are still wary of the possibility of a third wave occurring. In addition to the risk of a spike in cases in the midst of the Christmas and New Year holidays, recently the World Health Organization (WHO) announced a new variant of COVID-19 called the Omicron variant.
What is the Omicron variant of COVID-19?
On November 26, 2021, WHO announced the existence of a new variant of the SARS-CoV-2 virus called Omicron. This variant was first reported to WHO from South Africa on 24 November 2021.
Not long after, WHO immediately stated that variants that had strain B.1.1.529 as a variant category needed to be wary of (variants of concern). That means, this variant has characters to watch out for such as the Delta , Gamma, Beta, and Alpha variants.
The Omicron variant has about 30 combinations of mutations from a number COVID-19 variants such as C.12, Beta and Delta. It is feared that mutations in the spike protein possessed by Omicron will make the virus more contagious than the Delta variant and allow reinfection or repeated infection.

Until now, WHO is still conducting more in-depth observations of this new variant and will continue to update information in accordance with the research conducted. Even so, WHO emphasized that the vaccines, treatment and prevention that had been carried out so far were still effective against various variants of the virus that causes COVID-19.
Distribution of the Omicron COVID-19 variant
This variant was first reported by South Africa to WHO on November 24, 2021. South Africa has experienced three waves of COVID-19 outbreaks, the last wave being dominated by the Delta variant.

However, in the last few weeks, COVID-19 infections have sharply increased again along with the discovery of the B.1.1.529 strain.
Apart from South Africa, several countries that have confirmed cases of variant B.1.1.529 are the UK, Canada, Hong Kong, Botswana, Australia, Italy, Belgium, and the Republic of Indonesia. Czech. In addition, this variant is also likely to have entered Germany, Denmark, the Netherlands, and Austria.
The emergence of this new variant raises concerns, including for the government and the people of Indonesia. Recent developments state that the Omicron variant has been detected in Indonesia as of December 16, 2021.
Researchers are still conducting further observations, to find out the cause of the spike in Covid-19 cases in Africa related to the spread of new variants or the presence of other factors.
How is Omicron different from other COVID-19 variants?
Compared to the previous Delta variant, the B 1,1,529 variant replicates itself 70 times faster in the tissues lining the airways, which can facilitate person-to-person spread.
However, in lung tissue, this variant replicated 10 times slower than the original version of the coronavirus. This indicates the effect on the lungs is quite mild or not severe.
Dr. Michael Chan Chi-wai emphasized, “It is important to note that the severity of the disease in humans is not only determined by the replication of the virus but also by the immune response of each person to the virus. An infection that can sometimes progress to life-threatening inflammation.”prevent hit by omicron
Previous studies reported a possible 1.1,529 B variant that was not detected by antigen testing. However, recent news suggests that antigen tests may take longer to detect this new variant. The FDA also confirmed that the antigen test can detect the variant, but the sensitivity is lacking.
The study, published this December in the British Medical Journal , showed that patients infected with the omicron variant had the most common complaints, including:
- Have a cold
- Fatigue (either mild or severe)
- Constantly sneezing
- Sore throat
“Most have runny noses, sore throats, and stuffy noses,” said Dr. John Vanchiere of the Center for Emerging Viral. “The cough is lighter than the previous variant. Some don’t have a cough at all, fever is rare.”
These symptoms appear more quickly after a person is infected. The incubation period, or the time it takes to develop symptoms after exposure, is about three days. Meanwhile, the Delta variant took about four days, and the original variant took more than five days.
Most people infected with the Omicron variant have mixed symptoms that recover relatively quickly and do not require hospitalization.
It is possible, there are also some patients who feel the typical symptoms of most cases of Covid-19 , namely:
fever characterized by an increase in body temperature,
a persistent cough for more than an hour, or several 24-hour coughs that are worse than a normal cough, and
loss of the ability to smell and taste food (anosmia).
If you or your family at home are experiencing the symptoms of Covid-19 mentioned above, especially anosmia, immediately see a doctor to confirm the condition further and get the right treatmenent. you can use herb for prevent.
Is it possible to vaccinate against the Omicron variant of COVID-19?
Early research suggests there may be an increased risk of reinfection with this variant. That is, people who have previously been infected with COVID-19 will be more easily re-infected with this variant.
However, information on this matter is still limited, and researchers are still conducting further observations.
Variant B 1.1529 gripped cells more tightly, holding back some antibodies. Some antibodies can provide resistance to this virus, but some cannot provide resistance because the virus attaches very tightly.
This may decrease the efficacy of the vaccination. Even so, the COVID-19 vaccine continues to be the right step to protect someone from infections that cause severe symptoms and reduce the risk of death if exposed.
Researchers think booster vaccination may offer more protection, so this is under further investigation. Currently in Indonesia booster vaccines are only intended for medical personnel.
In addition to vaccines, prevention of the spread of the COVID-19 virus can also be done by wearing masks, diligently washing hands, avoiding crowds, and reducing mobility. Several countries have also restricted the entry of tourists from countries with confirmed cases of variant B.1.1.529, and tightened self-quarantine for people who have just arrived from abroad.
As of November 29, 2021, Indonesia has also imposed a temporary entry ban on arrivals from countries confirmed to have Omicron cases, enforced 14-day quarantine for arrivals from countries that may have this variant, and tightened other entry requirements.
Meanwhile, we must remain disciplined in carrying out health protocols by maintaining distance, staying away from crowds, avoiding traveling abroad, and wearing masks. If you have not received the vaccine, immediately visit the nearest health facility to register for the COVID-19 vaccination. we dont know life after coronavirus..
