Prof. Dr. Yong Phuworawan, Head of the Center of Specialization in Clinical Virology Department of Pediatrics Faculty of Medicine Chulalongkorn University Post a message about COVID-19, the JN.1 strain is a strain that is now very common.
Finally, it is expected that the JN.1 strain that is widespread and highly contagious It has become a main species in Thailand.
From a study by the Virus Center Decoding the genetic code In December, 14 samples (there are still a few waiting to be analyzed) with a limited budget. It was found that the most common dominant species It is already the JN.1 strain. After this new year, the JN.1 strain will be the main strain. or mostly Because it is a more contagious strain than previous strains.
The JN.1 strain was first found in the United States. It is a child of the BA.2.86 strain (Pilora, the name of the asteroid). It is a highly contagious strain that spreads quickly. It is predicted that this species will replace all other species.
As expected This species came to Thailand. It will start to become more pronounced in December and definitely after the new year. It is probably the JN.1 strain, a new strain that currently doesn’t have a nickname.
People infected with the JN.1 strain have mild symptoms. Some people just have a cold. Sore throat like any other respiratory disease. Easy to contact Once it is, it can be 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 begin to decrease after entering 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 have followed the breed all the time. Due to a limited budget Therefore, the amount cannot be made much. To monitor the trend of strains occurring 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 strains will be JN.1 because they spread more easily than other strains.
The severity of the disease has not changed. The important thing to study now is What effect does the existing immune system have? with the change of new species By bringing new species It came because the germs multiplied. Then tested with immune reactions in Thai people who received various types of vaccines. and past infections
