Canada has expanded its dengue travel advisory to cover the Philippines, placing the Southeast Asian nation alongside Cuba, Belize, Cambodia, China, Vietnam and a growing list of destinations where travelers face heightened risk from the mosquito borne virus.

New Advisory Reflects Widening Global Dengue Threat

The updated notice, published by the Government of Canada’s travel health service in late November 2025, consolidates a broad roster of countries under a single dengue advisory as case numbers remain elevated across multiple regions. The advisory is classified as Level 1, meaning travelers are urged to take standard but diligent precautions to avoid mosquito bites in affected areas.

The dengue notice now explicitly names the Philippines alongside a mix of Caribbean, Central American, African and Asian destinations including Belize, Cuba, Cambodia, China, Vietnam, Mexico, Pakistan and several Pacific island states. Health officials say the grouped approach reflects the reality that dengue is no longer confined to isolated outbreaks, but has become a persistent risk across much of the tropics and subtropics.

While Canada has issued periodic dengue advisories for years, the current configuration underscores the extent to which the virus has become entrenched in popular holiday and business travel markets. The latest update arrives as Canadian travelers book winter and spring trips, putting destinations such as the Caribbean, Central America and Southeast Asia squarely in focus.

Officials stress that the advisory is precautionary and does not recommend against travel to the listed countries. Instead, the emphasis is on preparation, early recognition of symptoms and responsible behavior on return to Canada, particularly during the peak mosquito season at home.

Why the Philippines Was Added to Canada’s Dengue Watch List

The Philippines has long been classified by international health agencies as a country with frequent and continuous dengue transmission, driven by its tropical climate, dense urban centers and widespread presence of Aedes mosquitoes that thrive in standing water. In recent seasons, periodic surges in infections have strained local health systems and prompted targeted vector control campaigns.

For Canadian authorities, the inclusion of the Philippines in a formal dengue travel notice aligns national advice with the risk categorizations used by bodies such as the United States Centers for Disease Control and regional health organizations. These institutions have consistently flagged the Philippines as a location where travelers face a sustained baseline risk of dengue, rather than a place where the virus appears only sporadically.

Travel patterns also play a role. The Philippines is a significant destination for Canada’s Filipino diaspora as well as for tourists drawn by beach resorts, diving sites and cultural travel. Canadian clinicians have reported regular cases of dengue in travelers returning from the archipelago, particularly following school holidays and winter breaks, reinforcing the rationale for specific guidance.

By naming the Philippines in the same breath as Cuba, Belize, Cambodia, China and Vietnam, Canadian health officials are signaling that travelers should approach all of these destinations with a similar level of vigilance, especially during rainy periods when mosquito breeding accelerates.

In the Americas, the Canadian dengue advisory highlights Belize and Cuba, both of which sit in a region that has experienced intense transmission in recent years. Regional health bodies have repeatedly urged Caribbean and Central American governments to strengthen mosquito control and surveillance as case counts climbed through 2024 and 2025 and seasonal peaks became more pronounced.

Cuba has faced extended periods of dengue activity, with traveler based surveillance from North America detecting consistent flows of infections linked to the island even when local reporting was limited. At the same time, shortages of basic supplies and intermittent power cuts have complicated efforts to eliminate mosquito breeding sites in some communities.

Belize, better known internationally for its barrier reef and jungle lodges, is part of a belt of Central American countries where dengue circulates every year. Canadian authorities note that the risk is not confined to cities: rural eco tourism, river trips and coastal stays all bring visitors into environments where Aedes mosquitoes are present.

The advisory links these destinations to a broader picture across the Americas, where the Pan American Health Organization has warned of successive record breaking dengue seasons. For Canadians escaping the winter for beach holidays or cruises, the message is that sun and sea now come with a clear, if manageable, vector borne health risk.

Asia’s Dengue Hotspots: Cambodia, Vietnam, China and Beyond

In Asia, Cambodia and Vietnam remain among the region’s most dengue affected countries, with transmission entrenched in both urban neighborhoods and rural provinces. Rapid urbanization, patchy waste management and warm, wet seasons have created ideal conditions for mosquito populations to flourish, and outbreaks among local populations are a recurring feature of the rainy months.

China appears on the Canadian list with an important caveat echoed by international agencies: dengue risk is concentrated in specific southern and subtropical regions, particularly along the country’s southern coast, while large swathes of the interior and north remain unaffected. Travelers heading to places such as Guangdong and neighboring provinces during warmer months are at most risk, while those visiting Beijing or other northern cities typically face minimal exposure.

Canada’s advisory effectively bundles these diverse Asian destinations under a single piece of guidance, but local risk can vary significantly within each country. Urban versus rural settings, time of year, altitude and the intensity of local mosquito control programs all influence the likelihood of exposure.

For travelers, this means that generic country level advisories should be supplemented with itinerary specific planning. Visits to temples and markets in low lying Cambodian cities, motorbike tours through Vietnamese coastal towns or extended stays in southern Chinese ports will carry a different risk profile from short business trips to high rise districts or cooler inland regions.

How the Canadian Dengue Advisory System Works

Canada’s dengue notice sits within a broader framework of travel health advisories that categorize risks by disease, destination and recommended precautions. For dengue, the current notice is issued as “Dengue: Advice for travellers” at Level 1, signaling that the main expectation is for informed, preventive action rather than avoidance of travel.

Behind the scenes, the Public Health Agency of Canada and its partners draw on multiple data streams, including international surveillance reports, alerts from organizations such as the World Health Organization and the Pan American Health Organization, and patterns seen in Canadian travelers returning with dengue infections. Recent research on travel associated dengue suggests that such traveler data can help flag periods of intensified transmission in destination countries.

The list of named countries is not exhaustive; instead, it represents a curated subset where Canadian officials judge the risk to be most relevant to outbound travelers at a given time. The inclusion of destinations such as American Samoa, Samoa, Tuvalu and several African states alongside the Philippines, Cuba, Belize, Cambodia, China and Vietnam underscores how geographically wide dengue’s footprint has become.

The advisory is reviewed periodically, and destinations may be added or removed as epidemiological conditions change. However, health authorities caution that the absence of a country from the list does not imply zero risk, particularly in regions where dengue has been documented in the past.

What Canadian Travellers Are Being Urged to Do

With the expanded advisory, Canadian officials are focusing on practical behavior rather than alarm. Travelers heading to the Philippines, Cuba, Belize, Cambodia, China, Vietnam or any of the other listed countries are being urged to consult a travel health clinic well before departure, ideally six weeks in advance, to receive tailored advice based on their itinerary and medical history.

There is currently no widely recommended dengue vaccine for the general travelling public in Canada, so preventive efforts center on avoiding mosquito bites. Authorities advise using insect repellents containing DEET or other approved active ingredients, wearing long sleeves and pants in light colors, and choosing accommodations with air conditioning or intact window screens whenever possible. In some high risk settings, sleeping under bed nets can provide an extra measure of protection.

Travelers are also encouraged to be alert to symptoms such as sudden high fever, severe headache, eye pain, joint and muscle aches, nausea, vomiting or rash in the days after arrival in, or return from, an affected country. Early medical assessment is critical, particularly for people who have had dengue before, because repeat infections can carry a higher risk of complications.

Canadian clinicians, for their part, are being reminded to ask about recent travel history when evaluating patients with flu like illness, especially outside the typical influenza season. Prompt diagnosis not only improves individual outcomes but also feeds back into surveillance systems that shape future travel notices.

Implications for Tourism in the Philippines and Other Affected Destinations

For tourism authorities in the Philippines and elsewhere, Canada’s expanded dengue advisory poses a communications challenge rather than an outright threat to arrivals. Travel health notices of this type are not travel bans, and most experienced travelers are already accustomed to managing insect borne risks in tropical settings.

Industry stakeholders in Southeast Asia and the Caribbean have instead framed the advisory as an impetus to strengthen local mosquito control and to improve public information campaigns. Hotels, resorts and tour operators are increasingly foregrounding their efforts to eliminate standing water, maintain screened rooms and provide repellents, turning vector control into a visible part of their service offering.

Destinations such as beach provinces in the Philippines, heritage towns in Vietnam and coastal resorts in Cuba are also working to reassure visitors that medical care is available should they fall ill, though access and quality can vary by region. Canadian officials, in turn, note that travelers should consider purchasing travel health insurance that covers emergency care and medical evacuation when visiting higher risk countries.

In practical terms, the advisory may encourage some travelers to adjust the timing of trips to avoid peak rainy seasons or to prioritize urban itineraries with better infrastructure. However, for most Canadians, dengue will be one more factor to weigh alongside weather, cost and safety in choosing where and when to go.

Growing Alignment Among International Health Agencies

Canada’s expanded dengue advisory mirrors a broader shift among global health agencies toward more proactive communication about vector borne diseases. The United States Centers for Disease Control has published updated risk maps showing large portions of the Caribbean, Central America and Southeast Asia as areas with frequent or continuous dengue transmission, while also identifying higher than expected case numbers among returning travelers.

Regional bodies in the Americas have repeatedly sounded the alarm over record breaking dengue seasons, urging countries to strengthen surveillance, clinical management and community engagement. In Asia, national health ministries have stepped up campaigns aimed at reducing household mosquito breeding sites and improving public understanding of early warning signs.

By explicitly naming the Philippines alongside Cuba, Belize, Cambodia, China, Vietnam and other destinations in a single advisory, Canada is bringing its own travel health messaging into closer alignment with this international consensus. The approach emphasizes that dengue is now a routine, predictable risk in many travel hotspots rather than an occasional anomaly.

For travelers, that means dengue preparedness is likely to become a standard part of trip planning whenever warm, humid destinations are on the itinerary. As Canadian and international authorities refine their surveillance and communication tools, future advisories may become more finely tuned to seasonal spikes and regional differences, but the underlying message is unlikely to change: in much of the modern travel map, dengue is here to stay, and precautions are no longer optional.
