Detailed explanation-1: -One way in which travel helps infectious diseases to spread is by the introduction of a new microorganism into a new geographic area. A novel pathogen entering a population with no previous experience of this microbe causes the most severe disease.
Detailed explanation-2: -The most common causes are viruses, bacteria, fungi and parasites. Infectious diseases usually spread from person to person, through contaminated food or water and through bug bites.
Detailed explanation-3: -Some infectious diseases are contagious (or communicable), meaning they are capable of spreading from one person to another. Other infectious diseases can be spread by germs carried in air, water, food, or soil. They can also be spread by vectors (like biting insects) or by animals to humans.
