The corona virus B1;466.2 is one of 12 SARS-CoV-2 variants that are included in the WHO priority list for further monitoring.
According to WHO data; 85 percent of the B1;466.2 variant has so far been found in Indonesia; 5 percent found in Malaysia; 4 percent found in Singapore; 1 percent each in Australia and Japan.
The Indonesian Institute of Sciences (LIPI) said that the local variant B.1.466.2 even had a massive spread in Indonesia before the Delta variant attacked.
According to researchers from the LIPI Biology Research Center; variant B.1.466.2 had dominated transmission in Indonesia in up to 57 percent of Covid-19 cases in March 2021; before finally the Delta variant attacked and dominated more than 80 percent.
However; currently; the variant tends to be a minority and the proportion is less than 5 percent in mid-June-July; after the Delta variant dominated Covid cases in Indonesia to 92 percent.
LIPI said that variant B.1.466.2 was first discovered in Bekasi on November 12; 2020. WHO has put variant B.1466.2 under monitoring since April 28.
This variant called LIPI has changes in genetic material that are thought to affect the characteristics of the virus or are thought to pose a risk in the future.
But the evidence for a phenotypic or epidemiological impact is currently unclear; requiring further monitoring and new scientific evidence.
There are also several other variants that are dominant in Indonesia; namely B.1.470; B.1.1.398; and B.1.459.
Variant B.1.470 was found in Surabaya 9 April 2020; B.1.1.398 in Jakarta on 5 June 2020; and B.1.459 in NTB on 1 June 2020.
Meanwhile; so far; WHO has three categories of monitoring coronavirus mutations.
The three categories consist of variants of the corona virus of concern (VoC); variants of interest (VoI); and variants that require further close monitoring (Alerts for Further Monitoring).
