The Ministry of Health (Kemenkes) said it had identified at least 330 cases of the stealth Omicron variant or BA.2 subvariance in Indonesia. This information was announced by Dr. Siti nadia Tarmizi M.Epid, as the spokeperson for COVID-19 Vaccination of the Ministry of Health. She informed us that the case of the  new variant of Omicron in Indonesia, was obtained from the Whole Genome Sequencing (WGS) examination; on samples of COVID-19 patients.

The purpose of examining the sample using this WGS is to provide an overview of what variants currently dominate in a particular region. “We have detected approximately 330 (infection cases) of BA.2, this (number) the proportion is still small if we compare it with BA.1.1, BA.1 (about) 5,000 cases that we found,” he said quoted from Kompas. com,

Thursday (3/3/2022). To note, the BA.2 subvariance is a lineage of the Omicron variant mutation. The Omicron variant itself has several sub-variants including BA.1, BA.1.1, BA.2, and BA.3.

Treatment remains the same, the virality of the virus itself that still hard to contained

Regarding the BA.2 stealth Omicron variant, Nadia explained, the subvariant or variant of the corona virus is actually not a routine examination of cases of COVID-19 infection. Because, regardless of the variant, the treatment and patient care remains the same. “But what is important is that we understand the pattern of distribution, so we identify the variant through the surveillance system, so it is a sample taken at random representing positive samples in Indonesia,” he added.

So, can this new variant of Omicron detected by PCR test?

Doctor Nadia said that the variants of the corona virus; including Alpha, Delta, Beta, and Omicron; could not be detected by ordinary PCR tests. However, the results of the PCR and rapid antigen tests are still considered sensitive to show positive or negative COVID-19. “It can’t be (detected by ordinary PCR); all variants cannot be examined with ordinary PCR. It must be done through genome sequencing,” explained Nadia explaining that the stealth Omicron as not detected by ordinary PCR.

Just like every living organisms, either multiply or breed into yet another new kind of monster

Thus, through Whole Genome Sequencing examination. It is possible to distinguish the Omicron lineage that infects whether the subvariant is BA.1.1, BA.1, BA.2, or BA.3. She added that the ‘BA.2 stealth Omicron’; also dubbed as the ‘Son of Omicron’; has the ability to evade the results of the S-gene Target Failure (SGTF) examination.

“This stealth variant, right, is called BA.2. Why do you say that because usually (in the variant) we cannot detect the Omicron protein S because there is a mutation in the S protein,” said Nadia. “(In) BA.2 there is no SGTF phenomenon. So the SGTF examination to determine whether it is possible for someone to be probable Omicron; can be detected on the WGS examination,” he continued.

Nadia explained that the symptoms of stealth Omicron BA.2 tend to be the same as other variant infections. Namely disorders of the respiratory tract. He further said that in the Delta variant; shortness of breah, loss sense of smell (asnomia), and fever; are the symptoms that can be found in the Delta variant of COVID-19.

However, Omicron’s symptoms were found to be much milder than its predecessor. Nadia also revealed some of the symptoms of the stealth Omicron that most patients complain about; including: Sore throat Fever Runny nose or body feeling sore and feverish
