No one wants to get unnecessary vaccinations. However, you can get exposed to a lot of different diseases when you travel. For example, many poorer countries don’t have the water quality or sanitation measures of other countries. You can get exposed to Typhoid, Hepatitis A, and others.
Vaccinations are optional in most countries you will visit, but that doesn’t mean you shouldn’t get them. And for a select number of countries certain vaccinations are mandatory, which can also depend on where you are traveling from. Take some time to look into this at least a month or so before you travel.
The Centers for Disease Control and Prevention (CDC) is the source of this information in the United States. They do a great job providing recommended vaccinations as well as travel precautions. Other countries will have similar organizations that provide the same information.
Find Out if You Can Drink the Water, This is one of the biggest mistakes people make when traveling, and it can cost you time out of your trip and a miserable few days.
Before you travel, determine if you can safely drink the water. Now, the water is a little different anywhere you go as it has different microbes in it, so you have the potential to have some stomach upset regardless. So, even if you can drink the water, go easy on local water at the start of your trip.
There are places where it is highly advised to not drink the water. You can purchase bottled water, or be eco-friendly and purchase a filtration bottle or a water sterilizer like a Steripen. Both options work great and can keep you safely enjoying your trip.
