Bangkok: The COVID-19 situation in Thailand has shown an increasing trend compared to the previous week, with the Department of Disease Control, Ministry of Public Health, reporting no deaths or cluster outbreaks. The public is encouraged to monitor symptoms and adhere to preventive measures, particularly those in vulnerable groups such as young children and individuals in high-risk categories. Those entering crowded areas are advised to wear masks and practice frequent handwashing. Medical attention should be sought immediately if symptoms occur.
According to Thai News Agency, Dr. Montien Kanasawasdi, Director-General of the Department of Disease Control, presented data from the Communicable Diseases Agency Singapore, indicating that between May 10-16, 2026, there were 12,700 new cases reported, marking an increase of approximately 8,000 cases from the previous week. Hospitalizations have risen from an average of 56 to 73 patients per day, with one ICU patient reported daily. The NB.1.8.1 variant remains the predominant strain, detected in over half of all cases in the country. In Thailand, the Disease Surveillance System reported a cumulative total of 3,642 COVID-19 cases and one death as of May 23, 2026. The majority of cases are among individuals aged 30-35, followed by those over 60, and then the 20-29 age group. Although cases have increased, they remain below the 5-year median. Surveillance data from the National Institute of Health Research, Department of Medical Sciences, indicates that NB.1.8.1 accounts for 50.95% of samples tested, with JN.1 and XEC identified at 24.97% and 9.14%, respectively. In 2025, clusters of outbreaks were noted during April-June, with NB.1.8.1 as the primary strain during this period. The variant's mutations in the spike protein facilitate easier transmission and immunity evasion, though there is no evidence it causes more severe disease.
Dr. Direk Khampaen, Deputy Director-General of the Department of Disease Control, stated that COVID-19 in Thailand is considered an endemic or seasonal disease. Despite decreasing severity and outbreak trends, maintaining preventive measures remains essential. The public is urged to practice frequent handwashing, cover their mouth and nose when coughing or sneezing, avoid crowded areas, wear masks, and avoid contact with people exhibiting respiratory symptoms, especially among high-risk groups. Those experiencing symptoms such as fever or cough should undergo ATK testing and avoid contact with others. Positive cases should seek immediate medical attention.
