Overview of the Current Situation
As of May 2025, both China and Thailand are experiencing significant surges in COVID-19 cases, attributed to the emergence of new variants and changes in public health measures.
🇨🇳 China: Surge Driven by JN.1 Variants
China is witnessing a substantial increase in COVID-19 infections, primarily due to the spread of new sub-lineages of the JN.1 variant, including JN.1.16, JN.1.18, KP.2, and KQ.1. These variants are characterized by enhanced transmissibility and immune evasion capabilities, leading to a rise in severe cases and hospitalizations .
The Chinese Centers for Disease Control and Prevention (CDC) have reported daily new cases ranging between 20,000 to 25,000, with a notable increase in critical cases and fatalities . In response, authorities are intensifying efforts to control the outbreak through enhanced testing, contact tracing, and vaccination campaigns.
🇹🇠Thailand: Increased Hospitalizations Amidst Rising Cases
Thailand is also experiencing a resurgence in COVID-19 cases, with a significant uptick in hospital admissions. In the week leading up to April 27, 2024, there were 1,672 new admissions and 9 deaths, with 390 patients in serious condition, 148 of whom required mechanical ventilation .
The increase in cases is attributed to the higher transmissibility of the currently circulating JN.1 strain and decreased adherence to preventive measures during public gatherings. Health experts recommend that individuals, especially those at higher risk, continue to use personal protective measures such as masks and hand hygiene .
Understanding the JN.1 Variant
The JN.1 variant, a sub-lineage of Omicron, has been identified as the predominant strain in both China and Thailand. This variant exhibits increased transmissibility and immune evasion properties, leading to higher infection rates and potential severity of illness. Current vaccines and treatments remain effective against this strain, but ongoing surveillance and adaptation of public health strategies are essential to manage its spread.
Protective Measures and Recommendations
-
Vaccination: Ensure full vaccination, including booster doses, as recommended by health authorities.
-
Hygiene Practices: Regular handwashing and the use of hand sanitizers can reduce the risk of transmission.
-
Mask Usage: Wearing masks in crowded or enclosed spaces can help prevent the spread of the virus.
-
Monitoring Symptoms: Individuals experiencing symptoms should seek testing and medical advice promptly.
-
Stay Informed: Keep up to date with information from reliable sources such as the World Health Organization and local health departments.
Frequently Asked Questions (FAQs)

The JN.1 variant is a sub-lineage of the Omicron strain of the SARS-CoV-2 virus. It is characterized by increased transmissibility and the ability to partially evade immunity from previous infections or vaccinations.
2. Are current vaccines effective against the JN.1 variant?
Yes, current vaccines remain effective in preventing severe illness and hospitalization due to the JN.1 variant. However, ongoing monitoring and potential updates to vaccine formulations may be necessary.
3. What are the symptoms of COVID-19 caused by the JN.1 variant?
Symptoms are similar to those of previous COVID-19 strains and may include fever, cough, fatigue, loss of taste or smell, and difficulty breathing. Individuals experiencing symptoms should seek testing and medical advice.
4. How can I protect myself from COVID-19 during this surge?
Adhere to recommended preventive measures such as vaccination, mask usage in crowded or enclosed spaces, regular hand hygiene, and monitoring for symptoms.
