It is important for travellers to take preventative steps to ensure their health and safety while they are exploring. There are many preventable illnesses that travellers can contract without the proper travel shots and immunizations. Here are some interesting epidemic disease statistics and facts we compiled:

Epidemic disease stats in 2018 are as follows:

Measles (1 million)

HIV/AIDS (1 million)

Hepatitis B (1.1 million)

Malaria (2.1 million)

Diarrhea (3.1 million)

Education is paramount in our effort to help our travellers – the first step is understanding localized diseases and how to best avoid these destination-specific health risks. Step two is taking the proper precautions, like meeting with a Travel Medicine Consultant, and carefully planning your destination itinerary.

The Americas

If you’re visiting the Americas, it’s recommended you get a number of immunizations to protect from common diseases:

Depending on your itinerary, it can be a good idea to also have a rabies vaccination. Rabies vaccinations can also be administered post-exposure, as long it is in a timely manner. Yellow fever is also a risk in some parts of South America. Cholera is common in developing countries and if left untreated, can result in death.

Travellers who are visiting some parts of South America, like Peru, can be at risk of contracting the Zika virus. The virus can cause fever, rashes, severe headaches, joint pain and/or muscular or bone pain. There are no vaccines. You must avoid getting bitten by mosquitos. We suggest always travelling with mosquito repellant.

Europe

Depending on where you’re visiting in Europe, it’s a good idea to ensure you have your immunizations up to date. Ticks can be common in hot weather. Tetanus can be a risk. While Europe doesn’t have as many risks at the moment, it is best to get vaccinated and follow safety precautions.

Health tips for Africa:

  1. Make sure you are drinking clean water, this presents the largest risk.

Understanding Other Diseases That Are Rare Is Important

  1. Filariasis is a mosquito-borne disease that can cause disfiguring swellings; prevented by avoiding mosquitos.

  4. Japanese Encephalitis is a risk in parts of Southeast Asia. It’s a viral disease, transmitted by mosquitoes but most cases occur in rural areas.
  5. Schistosomiasis is at risk in Laos, Philippines, Vietnam and Sulawesi. This is a parasite that enters the skin after swimming in contaminated water.
  6. Measles are a problem in some parts of Southeast Asia. They are contagious and spread through coughing and sneezing.

  • Choose accommodation with screens and fans.
  • Use permethrin on clothing when in high-risk areas.
  • Wear long sleeves and pants in light colors to stay cool.
  • Use mosquito coils.
  • Spray your room with insect repellent before going out for your evening meal.

General Travel Medicine Guidelines

If a disease outbreak in an area appears to be particularly bad, it could be best to avoid that area altogether. However, many diseases on this list can be avoided by practicing good hygiene and taking precautionary measures with a travel medicine specialist. It sounds like common sense, but staying out of unsanitary conditions, and remaining vigilant against mosquitos are two major drivers of travel health.

In some cases, some disease exposure may be unavoidable, so having emergency numbers and knowing where your nearest medical centre is will help you to get treatment ASAP. It is important to note that not all diseases have treatment, so vigilance remains your best bet. It is makes sense, travel insurance can be a good safeguard because it can help cover medical and emergency costs if you do encounter a health issue while you are abroad.

Remember, the above information is just a general guide. It’s a good idea to stay as up to date as you can if you plan on travelling to countries on the list so that you can take important precautions and stay healthy. If you’re unsure, it’s always worth visiting a travel medical professional who will be able to advise you further.

The traveller’s lifestyle is all about carefree living, but don’t be carefree when it comes to your health. See the world, Safely.
