PUTRAJAYA, Oct 7 — Fifteen new clusters of influenza and respiratory tract infections were reported in Epidemiological Week (ME) 39/2025 compared to three clusters in the previous week, according to the Health Ministry (MOH).
In a statement, it said the majority of clusters involved educational institutions, including schools and kindergartens, with no deaths reported.
MOH said the cumulative number of clusters this year stood at 214, a decline of 33 per cent compared with the same period last year.
“Laboratory surveillance has confirmed no new mutations, with the rise in cases linked to existing strains, mainly Influenza A (H3), consistent with trends in the Southern Hemisphere. The increase in cases is likely driven by social activities and travel following the holiday season,” it said.
According to MOH, the Influenza-Like Illness (ILI) rate remained stable in September, ranging from 5.65 to 6.25 per cent.
Hospital admissions for Severe Acute Respiratory Infections (SARI) were recorded at 10.65 per cent in ME 38/2025 but declined to 9.59 per cent in ME 39/2025.
The ministry said it continues to monitor influenza trends and respiratory infection clusters through its reporting system and designated sentinel sites nationwide.
“Generally, influenza infections are mild and resolve within a week, but they can be severe among high-risk groups such as children, the elderly, pregnant women and individuals with chronic illnesses,” the statement added.
Taking into account the increase in cases and clusters in educational institutions, the MOH advised schools to monitor students showing symptoms and ensure immediate isolation, especially those staying in hostels.
The MOH also recommended the use of face masks among students, teachers and staff who are symptomatic or at high risk, as well as providing hand sanitisers, maintaining environmental cleanliness and promptly notifying the District Health Office in the event of rising cases.
It further reminded the public to maintain good personal hygiene, avoid sharing personal items, and observe proper cough and sneeze etiquette.
Those with symptoms are urged to rest at home and avoid public places. If leaving the house is unavoidable, they are advised to wear a face mask to reduce the risk of transmission.
“High-risk groups such as the elderly, young children, pregnant women and individuals with chronic illnesses are encouraged to receive seasonal influenza vaccination annually.
“The elderly can obtain the vaccine at selected Health Clinics,” MOH said.
According to the ministry, it will continue to monitor influenza trends locally and abroad, based on information from the World Health Organisation and regional authorities, while ensuring that prevention and control measures are carried out continuously.
