Answer:
Communicable, or infectious diseases
Step-by-step explanation:
Those are diseases caused by microorganisms such as a virus, parasites, or bacteria. They can be spread, either indirectly or directly. It can happen through contaminated food, bites from insects that can carry those microorganisms to another person, or even by being in contact with respiratory droplets.
In a globalized world where people travel around the globe in a much easier way, communicable diseases usually find a way to be spread to very distant places.
