Dr Yong said the Covid JN.1 virus will be the main strain in Thailand. In February the number of patients will decrease. Before the new season starts in June 2024.
January 11, 2024 Dr. Yong Phuworawan, Director of the Center for Specialization in Clinical Virology Department of Pediatrics Faculty of Medicine Chulalongkorn University posted on Facebook saying:
Dr Yong said that ultimately, the JN.1 strain is expected to be widespread and easily transmissible. It has become a major species in Thailand.
From the study of the virus center Decoding the genetic code In December 14 samples (there are still some to be analyzed) with a limited budget. It turned out that the most common dominant species IS already the JN.1 strain, and after this new year the JN.1 strain will be the main strain. or above all because it is a more contagious strain than previous strains.
The JN.1 strain was first found in the United States. It is the son of the BA.2.86 strain (Pilora, the name of the asteroid), a highly contagious strain that spreads rapidly. This species is expected to replace all other species.
As expected This species arrived in Thailand. It will start to become more pronounced in December and certainly after the new year. This is likely strain JN.1, a new strain that currently does not have a nickname.
People infected with the JN.1 strain have mild symptoms. Some people simply have a cold. Sore throat like any other respiratory disease. Easy to contact Once it is, it can be easy again. As a result, there is a rapid increase in the number of patients. Especially after this new year And it is expected that patients will start to decline after the entry of February. It will decrease significantly in March and then calm down until reaching the new season in June this year.
At this time, the center I followed the breed all the time. Due to a limited budget Therefore, the amount cannot be large. To track the trend of strains occurred in Thailand, as shown in the figure, it can be seen that the dominant strain in November was HK3 and then changed to JN.1 in December. And this month, most of the strains will be JN.1 because they spread more easily than other strains.
The severity of the disease did not change. The important thing to study now is What effect does the existing immune system have? with the change of new species Bringing new species It happened because the germs multiplied. Then tested with immune reactions in Thais who received various types of vaccines. and past infections
