Is the word Malaria capitalized in a sentence?

"Malaria" is not capitalized in a sentence unless it's at the beginning of a sentence or part of a proper noun.

Here's why:

* It's a common noun: Malaria refers to a disease, and diseases are generally not capitalized.

* Not a proper noun: It's not a specific person, place, or thing like "John Smith," "New York City," or "The Great Pyramid."

Example:

* "The doctor diagnosed the patient with malaria."

* "Malaria is a serious health concern in many tropical regions."
