No Zika cases in Johor, but state on high alert after Singapore infections
JOHOR BARU: There are no Zika cases reported in Johor, despite two confirmed infections in Singapore.
Following the recent cases reported across the Causeway, health authorities are on high alert and have heightened mosquito control and health surveillance. State Health and Environment Committee chairman Ling Tian Soon said entry protocols remain unchanged at all land, sea and air checkpoints to Johor.
"Singaporeans and other foreigners can continue to make their way into Johor.
"Screening protocol will continue at all entry checkpoints…anyone showing symptoms will be immediately referred for further testing at designated medical facilities," he told the New Straits Times today.
"There are no reported Zika cases in Johor as of now, and the Health Ministry has not issued any new directives. However, we remain vigilant," Ling added.
There are two confirmed Zika cases in Singapore's housing estate in Woodlands, some 5km away from the Johor's border land entry point via the Customs, Immigration and Quarantine (CIQ) complex at the Bangunan Sultan Ismail, here.
While Malaysia has not seen a Zika outbreak since 2016, Ling stressed the need for continuous preventive efforts, especially in Johor given its high volume of cross-border traffic.
Malaysia's last significant Zika concern occurred in 2016, when the first local transmission was confirmed in Sabah, shortly after Singapore reported a major outbreak in the Aljunied area.
Since then, Malaysia has reported sporadic cases, primarily imported or isolated incidents, but no major outbreak or cluster has been officially recorded.
As of June 2025, there has been no confirmed Zika outbreak in Malaysia resembling the 2016 episode in terms of scale or transmission pattern.
Meanwhile, Singapore National Environment Agency (NEA) in a statement issued on June 19 (Thursday) said NEA and the Communicable Diseases Agency (CDA) confirmed two locally transmitted Zika cases at Woodlands Street 11 and Street 32.
The viral traces were found in both mosquito and wastewater samples in the area which signalled a likely transmission.
Singapore, has deployed over 70,000 mosquito traps across the island, has recorded seven confirmed Zika cases this year.
The virus is spread mainly by Aedes mosquitoes, which is the same vector responsible for dengue. It can cause serious complications in pregnant women, including birth defects.
Zika symptoms include fever, rash, red eyes, and joint pain, although many infected individuals remain asymptomatic. There is currently no vaccine or specific treatment.
Ling urged Johoreans to stay alert and practise anti-mosquito measures such as removing stagnant water and using repellents.
He also advised pregnant women and those planning to travel to affected areas to consult medical professionals if they develop symptoms.
The public can follow updates through official channels and are advised to seek immediate medical attention if unwell.

Viability of using savings for medical coverage being assessed
KUALA LUMPUR: The proposal to let Employees Provident Fund (EPF) members use Account 2 for monthly health insurance premiums is still under review, says the fund. In a statement to the New Straits Times, EPF said it is working closely with the relevant authorities to assess the viability of the initiative. "EPF is aware of discussions on the proposal to allow the use of savings in Akaun Sejahtera (Account 2) to pay for health insurance premiums. "The proposal is still being considered, and the EPF is working closely with the relevant parties on the matter," it said. The fund added that, as with all proposals involving members' savings, a thorough assessment is being carried out to ensure any new measure balances short-term needs with long-term retirement security. "As with all proposals involving members' savings, careful assessment is being conducted to ensure that any new measures will strike a balance between immediate needs and members' long-term financial wellbeing." The EPF said further updates would be shared through official channels once available. On June 19, Health Minister Datuk Seri Dr Dzulkefly Ahmad said the government is considering allowing EPF members to use their Account 2 savings to pay for monthly health insurance premiums. He said that, if implemented, the initiative could enable 16 million EPF contributors to access private hospital treatment using their contributions. However, Dzulkefly later clarified that the proposed health insurance scheme — funded through EPF Account 2 — would be voluntary and not mandatory. The Association of Private Hospitals Malaysia (APHM) has welcomed the government's proposal to allow EPF members to use their Account 2 savings to pay monthly health insurance premiums, calling it a Its president, Datuk Dr Kuljit Singh, said while the plan is welcomed, it must be accompanied by clear safeguards to ensure its long-term sustainability. He said the responsibility now lies with the relevant agencies to determine the most appropriate funding model, whether through EPF or other mechanisms.

Role of households in dengue prevention from a technical, practical perspective
Published on: Saturday, June 21, 2025 Published on: Sat, Jun 21, 2025 By: Ir Ts KJ TAN, FIEM, JP Text Size: DENGUE fever, a mosquito-borne viral disease caused by the dengue virus (DENV), has remained one of the most pressing public health threats, particularly in tropical urban centers like Kota Kinabalu areas Sabah. Transmitted primarily by the Aedes aegypti mosquito, dengue infections continue to escalate despite years of government-led interventions such as fogging, larviciding, and public health education. While these strategies have played a role in limiting outbreaks, a persistent and frequently overlooked factor continues to undermine control efforts: the household environment. The Institution of Engineers Malaysia (IEM) has formulated Guidelines on the Prevention and Control of Dengue in which households form a critical frontline in the war against dengue. Understanding and addressing the factors that allow mosquitoes to breed within and around homes is key to breaking the cycle of transmission. The Aedes aegypti mosquito has evolved to thrive in human-made environments. Unlike other species that favor natural wetlands or rural ponds, Ae. aegypti actively seeks out artificial containers with clean, stagnant water for breeding. Commonly found habitats include buckets, roof gutters, potted plants, dish trays, old tires, and even bottle caps. Advertisement Its breeding and biting behaviors further increase its threat: Ae. aegypti bites during the daytime, especially early mornings and late afternoons, often inside homes or in shaded areas near dwellings. Their eggs can survive without water for months, hatching when water becomes available. The entire mosquito life cycle – from egg to larva to adult – can be completed in seven to 10 days under optimal conditions, making it highly efficient at establishing new colonies rapidly after rain or in homes with poor sanitation. Despite this biological advantage, Aedes mosquitoes are not invincible. The most effective weapon against them is not fogging or chemical treatment, but source reduction – the elimination of breeding grounds. In this context, the household becomes both a risk and a solution. Most mosquito breeding occurs within a 100m radius of human activity. Studies conducted in Malaysian cities have shown that more than 50pc of breeding sites are located within domestic settings, where household water containers, improperly managed waste, and poor drainage systems create ideal conditions. This reality highlights the critical need for residential-level interventions. The IEM Guidelines recommend that each household adopt a systematic and technical approach to prevent mosquito breeding. One of the most effective and simple measures is the weekly 10-minute inspection. Residents are advised to dedicate ten minutes each week to checking both inside and outside their homes for stagnant water. This includes commonly overlooked spots such as flowerpot trays, bathroom floor traps, kitchen sinks, laundry buckets, pet water dishes, and items left outdoors that may collect rainwater. However, inspections must go beyond simply tipping water out. Ae. aegypti eggs adhere to container walls and remain viable for months. Therefore, all water-holding items should be scrubbed, dried, and, where possible, stored in a dry position or covered to prevent refilling by rain or household use. A crucial but often under-managed aspect of residential design is water storage and rainwater harvesting. Many households, especially in semi-urban or water-insecure areas, rely on large containers to store water for cleaning or garden use. If these containers are left uncovered or only partially sealed, they become perfect breeding grounds. The IEM guidelines advise that all water storage should be fully sealed or covered with mosquito-proof mesh with apertures not exceeding 1.2mm. Additionally, rainwater harvesting systems should be designed with self-draining features, overflow outlets, and flush systems to prevent water stagnation in gutters, downpipes, and filtration components. Where sealing is not practical, safe biological larvicides such as Bacillus thuringiensis israelensis (Bti) may be applied periodically. Roof gutter systems represent another hidden danger. Improperly installed or poorly maintained gutters trap organic matter such as leaves and silt, leading to blocked drains and water accumulation after rainfall. Slopes that are too shallow or absent of overflow mechanisms exacerbate this issue. According to the IEM, gutters should be cleaned at least monthly, and ideally be fitted with leaf guards, inspection ports, and anti-mosquito mesh over drain outlets. Any system collecting roof water should be designed with adequate fall gradient to ensure efficient flow and prevent pooling. The same attention must be paid to sanitation and household plumbing systems. Bathroom floor traps, unused toilets, and rarely used sinks can become stagnant if the water seal is not regularly replenished. Leaky pipes under kitchen cabinets or external taps can also result in puddles that serve as mosquito nurseries. It is advised that homeowners perform plumbing checks quarterly and fix leaking connections promptly. Floor traps and gully traps not in use should be sealed or treated with cooking oil, which forms a surface layer that suffocates larvae. Another often neglected contributor is poor waste management. Discarded items such as broken toys, cans, unused flowerpots, or even polystyrene containers left in gardens or porches can trap rainwater. In high-rise buildings, recycling materials such as plastic bottles or food containers stored in open-air spaces pose additional risk. The guidelines recommend that recyclables be punctured and dried before storage and always kept under cover. Homes should also undertake regular decluttering, particularly in outdoor areas and balconies. Community recycling centers and municipal contractors should support proper collection and disposal to reduce container waste exposure. While engineering solutions and technical recommendations form the backbone of prevention, behavioral change is what ensures their sustainability. Dengue prevention should become part of the household's weekly routine, alongside tasks such as sweeping or taking out the trash. Children should be taught to report stagnant water or mosquito sightings, while household helpers or tenants must be equally informed. Awareness campaigns rooted in WHO's Combi (Communication for Behavioural Impact) model stress the importance of not just knowledge but habit formation. Posters, fridge magnets, and weekly SMS alerts have been successfully deployed in various localities to serve as reminders. When a suspected dengue case arises in a household, immediate containment is essential. The infected person should always sleep under a mosquito net, including daytime, to avoid being bitten by Aedes mosquitoes, which could then spread the virus. Simultaneously, the household should undergo a detailed inspection, not only of the patient's room but the entire compound. Neighbors must be alerted, and the local vector control unit – such as the Kota Kinabalu City Hall (DBKK) should be notified to conduct fogging or larviciding in the vicinity. In this effort, stakeholder collaboration is indispensable. Homeowners, property managers, developers, and municipal authorities must work together to address shared spaces and structural risks. Developers have a responsibility to incorporate mosquito-resistant design in new housing schemes. This includes proper landscaping to avoid water retention, the use of permeable pavements, well-graded drainage systems, and the installation of sealed water tanks and inspection-accessible gutters. For high-rise or gated communities, property managers must schedule quarterly inspections of rooftop water tanks, basements, and sump pits. Maintenance logs should be maintained and subject to health inspections. Local authorities play a crucial role in enforcement and education. DBKK and related councils must uphold existing health by-laws that prohibit the harboring of mosquito breeding sites. This can include issuing compound fines or warnings to households found in violation during routine checks. Equally important is the provision of public education materials in multiple languages to reach all segments of the population, including migrant workers and the elderly. Sabah's unique climatic and demographic conditions further intensify the need for household-level dengue resilience. The state's equatorial rainfall patterns and hot temperatures create year-round breeding conditions, while many residents live in low-density housing with access to outdoor space — increasing exposure to container habitats. During the monsoon season, when rain is frequent and intense, mosquito populations can surge rapidly, outpacing fogging efforts. Therefore, household preparation and maintenance must be intensified before, during, and after seasonal peaks. Historical data from Kota Kinabalu district show that dengue outbreaks have occurred in predictable cycles, often corresponding to periods of sustained rainfall and stagnation of preventive efforts. The National Crisis Preparedness and Response Centre (CPRC) has noted that case clusters frequently originate from residential areas where multiple breeding sites are found within proximity. In one notable case in KK district in 2022, over 60pc of the breeding sites were traced to household premises, despite weekly fogging efforts in public spaces. This highlights the irreplaceable role of domestic source control. In conclusion, household-level dengue control is not merely an auxiliary component of vector management – it is the foundation upon which all other strategies rest. Engineering controls, environmental design, behavioral adaptation, and policy enforcement must converge at the household level to sustainably reduce dengue transmission. The IEM Guidelines offer a scientifically grounded and practically implementable framework for empowering households to play a leading role in mosquito control. In a rapidly urbanizing city like Kota Kinabalu where human activity constantly reshapes the environment, household vigilance, maintenance discipline, and structural design must evolve in parallel. A mosquito-free home is not just a private benefit – it is public responsibility and a civic duty. As dengue continues to pose a threat to public health, the pathway to control lies not in complex technology, but in consistent, collective household action – one container, one drain, and one home at a time. * Follow us on our official WhatsApp channel and Telegram for breaking news alerts and key updates! * Do you have access to the Daily Express e-paper and online exclusive news?
