A malária sajátságosan a világ melegebb vidékein fordul elõ / vidékeire jellemzõ. // A malária a világ melegebb éghajlatú régióiban sok helyen fordul elõ / a melegebb éghajlatú régiók területeire jellemzõ.
"Usage: A disease that occurs regularly in a particular area, as malaria does in many tropical countries, is said to be endemic. The word endemic, built from the prefix en-, "in or within," and the Greek word demos, "people," means "within the people (of a region)." A disease that affects many more people than usual in a particular area or that spreads into regions in which it does not usually occur is said to be epidemic. This word, built from the prefix epi-, meaning "upon," and demos, means "upon the people." In order for a disease to become epidemic it must be highly contagious, that is, easily spread through a population. "
