Travelling is one activity that every individual must undertake at one time or the other; it does not matter what the purpose of travel is, or whether the travel is local or international. A lot of people actually look forward to travelling to other parts of the world for various reasons and purposes, including but not limited to business, tourism, vacation, pilgrimage, education and for medical attention.
The euphoria to travel outside of one's domain usually comes with a lot of preparations, and more often than not, a great deal of resources are deployed to ensure that the travel is actually takes place; and these include acquisition of an international passport, medical tests (where applicable), expensive visa processing fees, flight booking and hotel reservation.
A lot of people will do anything and everything just to actualise their international travel ambition. And to be very candid here, international travel is actually fun and something to look forward to. Travelling, especially international travels, is a form of education for the travellers as they have an opportunity to see new environments, meet new people, and learn how things are done elsewhere.
International travel affords the traveller a lot of opportunities irrespective of their original purpose of travel. These include business opportunities, educational opportunities, employment opportunities and even marital opportunities. Unfortunately, however, it is only these and many other opportunities that these (would-be) travellers see. They seem to be ignorant or care less about risks that are embedded in international travels, so they don't take any steps towards mitigating such risks.
