If you are someone who has traveled abroad a lot already, you are probably aware that many countries have specific requirements for vaccinations and other precautions before you visit them. This may seem like something that is sometimes overly cautious, given that the chances of contracting a lot of the diseases you need to be vaccinated against for travel are slim if you stay in tourist or business areas. However, public health and travel health are strongly tied together, and it is important that everybody is aware of their importance, even if they do not intend to travel to exotic locations where things like tropical diseases are a genuine risk.
Travel Health and the Spread of Disease Between Regions
One of the most important reasons why there are things like travel vaccinations is to stop the spread of diseases that exist in one region to other parts of the world. There are some places that have diseases carried by specific parasites, for example malaria, and there are also some places that have no available vaccination programs, so there are higher instances of things like tuberculosis than in most of the developed world.
Epidemiology and Public Health
The study of how diseases spread and lead to outbreaks is called epidemiology and is something that you can actually have a career in, where you can influence public health policies and plans for future travel vaccinations and travel health strategies.
A good way to get started if you are interested in doing this is to look into an online public health master’s degree. An online masters in public health will give you a good grounding in how important public health issues like travel health affect populations, and the kind of approaches that can be used on a public scale to help keep populations safe.
Optional Travel Vaccines and Medicines
While it is true that to visit certain locations, such as those with yellow fever, vaccinations are mandatory, you may be surprised to find that vaccinations are recommended even for countries where you may not expect it. In fact, for foreign people seeking to get visas for the USA, a selection of vaccinations are required, even though there are not really any special tropical diseases that somebody would be likely to contract here.
This can make it confusing when you are trying to decide what you need for a specific trip. The best thing to do is to talk to your doctor, as in some cases things like malaria medication, which is advised for a country like India, may not be specifically advisable for the trip you have planned due to the risk of side effects outweighing the risk of you actually catching malaria in the region you are going to and the places you plan to spend time in.
As you can see there are some very good reasons why everybody needs to be aware of the differences in risk of catching and spreading different diseases when they travel. It has been seen that some conditions that were originally isolated caused public health scares when patients displaying symptoms traveled between countries, for example with SARS. Be sure to talk to your doctor and also do your own research so that you can make sure you are protected when you travel.
