In a significant move, Health Canada and the Public Health Agency of Canada have issued an urgent travel health warning for travellers heading to Greece, Italy, Spain, and China. The advisory highlights the growing concern over leishmaniasis, a parasitic disease spread by sand flies. This warning comes as part of Canada’s ongoing commitment to ensuring the health and safety of its citizens, but it also raises questions about how this health risk may affect tourism in these popular destinations.
Leishmaniasis: What Is It and Why Is It a Threat?
Leishmaniasis is a parasitic infection caused by a parasite transmitted through the bite of an infected sand fly. While the disease can occur in various forms, the advisory specifically focuses on the visceral form, which is the most severe and potentially life-threatening. This form of leishmaniasis can take weeks, months, or even years to show symptoms after an infected bite. Unfortunately, there is no vaccine or preventative medication to protect against the disease, making prevention through bite avoidance the only reliable solution.
How Does Leishmaniasis Spread?
Sand flies typically bite in the evening or at night, making them particularly dangerous for travellers visiting rural and tropical regions. Their bites are often so small that they can pass through regular mosquito nets, meaning tourists may be unaware of the risks if they are not properly protected. As tourism continues to surge in these countries, the risk of exposure to leishmaniasis grows for the millions who visit annually.
The affected destinations, Greece, Italy, Spain, and China, have witnessed increasing tourism numbers over the past years, especially as international borders have reopened. Tourists flock to Greece for its ancient ruins, to Italy for its art and history, to Spain for its vibrant culture, and to China for its unmatched heritage. However, with leishmaniasis now posing a threat, these countries face potential impacts on their tourism industry.
Rural and Tropical Regions at Greater Risk
Health Canada warns that while the risk to general tourists remains low, the advisory is targeted at those visiting rural and tropical areas. Countries like Bangladesh, Ethiopia, Sudan, and Nepal have long been known for higher cases of leishmaniasis, particularly the visceral form. As more Canadians explore these areas, the concern about the spread of the disease is growing. The updated advisory suggests that heightened awareness and extra precautions are crucial for anyone visiting these at-risk regions.
Symptoms of Leishmaniasis: What to Watch For
Tourists should be aware that the symptoms of visceral leishmaniasis can take months or even years to surface. Common signs include:

- Fever
- Weight loss
- Enlarged liver and spleen
- Blood abnormalities, such as low blood counts
If left untreated, leishmaniasis can be deadly, and the disease remains a significant health concern for visitors to affected areas. The potential to fall ill months or even years after returning from a trip makes it crucial to inform healthcare providers about any travel history to these areas.
What Tourists Can Do to Protect Themselves
Canada‘s health authorities are stressing the importance of bite prevention as the most effective strategy to reduce the risk of infection. While there is no vaccine or treatment to prevent leishmaniasis, tourists can follow these safety measures to protect themselves:

- Avoid sand fly bites by using insect repellents and wearing protective clothing.
- Stay in air-conditioned rooms or under pyrethroid-treated bed nets (regular mosquito nets may not provide adequate protection).
- Sleep off the ground when camping to avoid exposure.
- Steer clear of animal burrows, where sand flies are more likely to reside.
These measures are especially crucial for backpackers, adventurers, and those planning to stay in rural areas, where the risk is higher. Given the lack of preventative vaccines, these basic yet vital steps may be the only line of defence against this potentially deadly disease.
How Leishmaniasis Could Affect Tourism in Greece, Italy, Spain, and China
The tourism industry in Greece, Italy, Spain, and China has grown steadily in recent years, with millions of visitors drawn to their rich history, beautiful landscapes, and cultural offerings. However, this health warning may have serious repercussions for their tourism sectors.
The heightened awareness of leishmaniasis could deter some travellers from visiting affected areas. The fear of contracting a disease that can surface years later may lead tourists to reconsider their travel plans. Additionally, certain parts of these countries, particularly rural regions, may see a decline in visitors, who are increasingly opting for urban destinations where the risk of infection is lower.
What Tourists Need to Know Now
While the risk remains low, tourists visiting Greece, Italy, Spain, and China should be prepared. Those planning to visit rural areas should take extra precautions. Travellers must ensure they are aware of the health risks and take proactive steps to avoid exposure. The travel health advisory highlights the importance of maintaining vigilance during travel, particularly when exploring regions with a higher risk of sand fly bites.
A Wake-Up Call for the Travel Industry
The travel and tourism industry may need to adopt new measures to ensure the safety of its visitors. Tour operators, hotel chains, and travel agencies must work with health authorities to provide essential information about leishmaniasis and offer guidance on how to protect against the disease. Health advisories like these underscore the importance of public health awareness in an increasingly globalized travel market.
As more tourists seek to explore new destinations, health risks like leishmaniasis can have a lasting impact on global tourism. It’s crucial for both travellers and the travel industry to stay informed and take the necessary steps to prevent the spread of such diseases.
