	Malaria was endemic in coastal areas. Practically everyone who lived in or traveled through these areas during the warm months experienced “seasoning,” which meant they suffered through the fevers and lassitude of malaria and other mosquito borne diseases.
	The word malaria comes from the Italian mal’aria  meaning “bad air.” Foul air, miasma, or swamp gas was deemed unhealthy. This cartoon portrays an epidemiological inquiry:
	Doctor: Any of your boarders got malaria?
	Landlady: Malaria! If you mean lying down and sleeping and grumbling and going to bed late and don’t get up at all mornings – if that’s the disease, they’ve all got it bad!
