23 December 2023 Dr. Anan Jongkaewwattana, Director of the Animal Health and Management Innovation Research Group The National Center for Genetic Engineering and Biotechnology (Biotech) posted on Facebook about the COVID-19 situation, the spread of the “JN.1” strain, which has recently spread rapidly in many countries. The details indicate that The JN.1 strain of Covid virus is a strain that is an extension of BA.2.86 that has changed in many places. It is expected that soon this species will come to dominate the area in Thailand. With the ability to spread the virus more quickly than other strains But this strain of virus has a change in only one position of the N (Nucleocapsid) protein, Q229K, which should not affect detection by antibodies to this protein in general ATK test kits.
Data from the University of Geneva, a WHO network, confirmed that various JN strains of the virus can still be detected by ATK (Abbot’s ATK is used in the test), but ATK is detected in samples with relatively high levels of virus. Ct from the RT-PCR test must be approximately 22. If it is higher than that, it may be released.
