Chagas Disease: What is it and why should you care?

Travel health doesn’t exist in isolation. Many health risks encountered by travellers are the same ones that local residents are exposed to every day. One such risk is Chagas Disease. Although it’s a low risk to most short-term travellers, around 7 million people are infected worldwide – mostly in Central and South America. Due to increasing internal migration (from rural areas to urban areas) and across borders, Chagas has become an international health priority. In recognition of International Migrants Day, we explore the challenges of controlling Chagas Disease, its impact on global health, and how it disproportionately affects migrating populations. What is Chagas? Chagas Disease (also known as American Trypanosomiasis) is named after Dr. Carlos Ribeiro Justiniano Chagas, the ...

5 Must-Read Articles on Climate Change and Infectious Diseases

Ever wonder how climate change impacts you as a traveller? Delays and unexpected costs related to extreme weather events, loss of biodiversity, and elevated air pollution levels are some of the things you may experience during your travels. The impact of climate change on our health extends beyond respiratory illnesses, increased heat strokes, and water shortages. Epidemiologists and evolutionary biologists have been sounding the alarm on the rise of infectious diseases for a long time.  In recent years we’ve seen a spike in vector-borne diseases which are also spreading to new regions. Here are a few that we’ve been tracking: Appearance of Chikungunya in the Caribbean Locally acquired Dengue in southern Florida, southern France, Italy, Portugal, and Japan West ...

Everything you need to know about Schistosomiasis

If your next adventure will take you rafting or swimming in fresh water, you should know about Schistosomiasis. What do snails have to do with travel health? You’re familiar with Yellow Fever, Malaria, and Traveller’s Diarrhea, but here’s one travel health risk you may not have heard of: Schistosomiasis. Also known as Bilharzia, Schistosomiasis is a parasitic infection transmitted by freshwater snails present in Africa and parts of Southeast Asia, South America, the Middle East, and some Caribbean islands. The culprit is the trematode flatworm parasite that is transmitted by small snails which are difficult to spot on the shores of lakes, rivers, streams and ponds. Coming into brief contact with fresh water contaminated with one of the eight ...

Come back with memories, not TB

Guest post by IAMAT Board member Shirley Cheng, MPH. Shirley has over 20 years of public health experience in both Canada and China.

Today is World Tuberculosis Day. One hundred and thirty years ago, the German doctor Robert Koch discovered the bacteria Mycobacterium tuberculosis which causes tuberculosis (TB). TB continues to be a global health concern: In 2010, 9 million people suffered from TB, 1.4 million people died from this infection, and one-third of the world’s population is at risk. The World Health Organization (WHO) has designated March 24 ...

Travel and Rabies: An Ongoing Concern

When rabies comes up in conversations, it’s often in veterinary clinics where our pets are vaccinated against infection. Rabies however, is also a major concern for travellers. More than 150 countries report rabies in their animal population putting humans at risk. The majority of human rabies cases are reported from Asia and Africa and 99% of cases are from dog bites. The World Health Organization estimates that 55,000 people die annually, although the illness is often misdiagnosed or under-reported. On a positive note though, the WHO states that 15 million people worldwide receive the post-exposure vaccinations, preventing an estimated 327 000 deaths annually. It’s not only travellers going on eco-tourism or adventure expeditions that are at risk. In many ...

Thinking About the Spread of Dengue and its Prevention

The recent dengue outbreaks, notably in the Philippines, USA (Key West), India (Delhi), and China (Guangdong province) got us thinking about why infection rates are on the increase and how the disease is spreading to areas previously believed safe from the virus. The dengue virus is primarily spread by infected female Aëdes aegypti (urban domestic) mosquitoes that bite during the day (dawn to dusk) both indoors and outdoors. The disease has become a major economic burden and serious public health concern in tropical and sub-tropical areas. According to the World Health Organization, there are approximately 50 million infections worldwide each year and 2.5 billion people are at risk of contracting dengue. However, under-reporting (because the patient did not receive ...

Polio No Longer A Real Threat? Think Again

The recent polio (poliomyelitis) outbreaks in Central Asia (Tajikistan, Uzbekistan, Russia) are reminders of how travel and migration can contribute to the re-emergence of a disease in a region previously declared free of infection. In Tajikistan, for example, the country was declared polio free in 2002, but this year alone 239 children became paralyzed and 15 patients have died of the disease imported from India. The disturbing news is that since 2003 there have been 25 countries – originally declared polio free – that have been re-infected. (Kenya, Uganda, Burkina Faso, Benin, Togo, Cameroon, Burundi, Central African Republic, Cote d’Ivoire, and Guinea are some of the countries that have since taken steps to control the reappearance of polio.) Travellers ...

Measles: Closer To Home Than You Think

Measles continues to be a threat all over the world, even making resurgences close to home. During the last decade we have seen measles outbreaks in places where this disease is considered a rare occurrence. The most recent cases were reported in Vancouver, British Columbia, and San Francisco and Amador Counties in California. Two factors explain the resurgence of measles in our communities: International travel and lack of immunization. The cases in Vancouver show that people who contracted the infection were not vaccinated or did not follow-up with the second dose required for effective protection. Add travel to the mix and you have the recipe for spreading this highly contagious disease. Here at home, even if you are not ...

Going to Haiti to Help? Health Advice for Aid Workers

We’ve been getting many online inquiries from people who are getting ready for aid missions in Haiti. Emergency relief efforts are underway to help Haitians recover from the devastating earthquake of January 12. Prior to the earthquake, Haitians were already struggling with access to health care, clean water, and proper sanitation. Only 11 percent of the population had access to water in their homes and the median life expectancy is 60 years. While the death toll continues to mount and survivors have to rebuild their lives, there is hope that reconstruction efforts can be done in such a way that Haitians affected by the earthquake will have universal access to proper shelter, food, and clean water. So what do ...
