Malaria rubra is commonly known as what?

Malaria rubra is commonly known as prickly heat. This term refers to the condition characterized by small red bumps on the skin, often accompanied by itching and discomfort. It typically occurs in hot and humid weather conditions, as sweat glands become blocked, leading to inflammation of the skin. The connection to the term "malaria" in this context refers to the appearance and sensations that resemble the itchiness sometimes associated with mosquito-borne illnesses, not to be confused with the actual disease malaria.

The other options describe different conditions or symptoms. Excessive perspiration is related to hyperhidrosis, while foul-smelling perspiration involves issues such as body odor, and an overgrowth of scar tissue pertains to keloids or similar skin conditions. Understanding these distinctions is vital as they relate to different aspects of dermatology and skin health.
