This data underlines the continued presence of evolving strains of the virus within the population.

Variant Breakdown and Trends

Genomic surveillance data reveals a complex landscape of circulating variants in Malaysia. Currently, the NB.1.8.1 variant remains dominant, accounting for 34% of reported cases. It is indeed followed by JN.1 at 18.1%, XEC at 13.3%, and XFG at 8.2%. The remaining 21.0% are attributed to other variants.

Notably, there has been a important decrease in overall Covid-19 cases. The number of cases recorded in the 35th epidemiological week represents a 49.5% reduction compared to the same period last year, which saw 85,297 cases. Despite this drop, ongoing surveillance remains crucial.

Variant	Percentage of Cases (ME 35/2025)
NB.1.8.1	34%
JN.1	18.1%
XEC	13.3%
XFG	8.2%
Others	21.0%

Current Health Situation and Precautions

Health officials have reported one Covid-19 related death in the latest epidemiological week. The deceased was a 91-year-old individual with pre-existing health conditions. This brings the total number of Covid-19 related deaths reported this year to three. The World Health Organization initially designated the XFG variant as a “variant under monitoring” on June 25th, citing concerns regarding its heightened transmissibility and potential for immune evasion, according to the World Health Organization.

Dr.Dzulkefly Ahmad reiterated the importance of continued preventative measures.He urged the public to practice frequent handwashing, wear face masks in crowded settings or when experiencing symptoms, and to prioritize vaccination, particularly for those in high-risk groups that include the elderly and those with compromised immune systems.

Understanding Covid-19 Variants

Viruses,including SARS-CoV-2 (the virus that causes Covid-19),constantly evolve through mutation. These mutations can lead to the emergence of new variants. some variants may exhibit increased transmissibility, higher virulence (severity of illness), or decreased susceptibility to existing vaccines or treatments. Genomic surveillance plays a critical role in identifying and tracking these variants, allowing public health officials to adapt strategies and protect populations.

The emergence of variants like XFG underscores the importance of maintaining high vaccination rates and continuing to practice preventative measures, even as the pandemic evolves. Staying informed about the latest developments and following guidance from health authorities remains vital in mitigating the ongoing risk of Covid-19.

Understanding the XFG Variant: What We Know So Far

On September 22, 2025, the Malaysian Ministry of Health confirmed the detection of the XFG variant of SARS-CoV-2, the virus causing COVID-19. This new variant has prompted immediate action from health officials, including a public address from the Health Minister urging heightened vigilance and adherence to preventative measures. Initial reports suggest the XFG variant exhibits increased transmissibility compared to previously circulating strains, though its severity is still under inquiry.

Key characteristics currently being studied include:

* Transmission Rate: Preliminary data indicates a potentially 20-30% increase in transmissibility.

* Severity of Illness: Current evidence doesn’t suggest XFG causes more severe illness, but monitoring is ongoing, particularly among vulnerable populations.

* Immune Evasion: Early lab studies suggest a moderate degree of immune evasion, meaning prior infection or vaccination may offer reduced protection. This doesn’t negate the benefits of vaccination, but highlights the importance of boosters.

* Symptoms: Reported symptoms appear consistent with other COVID-19 variants – fever, cough, fatigue, loss of taste or smell, sore throat, and muscle aches. However, some reports indicate a higher incidence of gastrointestinal symptoms.

Health Minister’s Urgent Recommendations

The Health Minister has issued a series of recommendations to the public to mitigate the spread of the XFG variant. These are not mandates at this time, but strongly advised actions:

1. Boost Vaccination: Individuals eligible for COVID-19 booster shots are strongly encouraged to receive them immediately.Boosters are crucial for maintaining a high level of protection, especially against new variants.
2. Mask Wearing: The use of high-quality masks (N95, KN95, or surgical masks) is recommended in crowded indoor settings, public transportation, and healthcare facilities.
3. Physical Distancing: Maintain a safe distance of at least 1 meter (3 feet) from others whenever possible.
4. Hand Hygiene: Frequent handwashing with soap and water or the use of alcohol-based hand sanitizers remains a vital preventative measure.
5. Stay Home When Sick: individuals experiencing symptoms of COVID-19 should isolate themselves and seek medical advice.
6. ventilation: Improve ventilation in indoor spaces by opening windows and doors or using air purifiers.
