[HideMe]Malaria

Malaria is no longer endemic in California. However, the disease is diagnosed in California residents every year, primarily as a result of contracting the disease in malarious areas outside the USA, and rarely, because of small focal outbreaks occurring as a result of importation of a case into an area when and where anopheline mosquitoes are prevalent.

Terms to describe the methods of acquiring human malaria cases have been developed by the World Health Organization and adopted by the Malaria Branch of the Centers for Disease Control and Prevention. They can be studied by selecting this link: Malaria Terms.

A thorough discussion of malaria occurring in areas where it is no longer endemic can be found by visiting the CDC malaria website.

Over the past several decades, California has had more cases of locally-acquired malaria than any other US state. To read an article summarizing subject of locally-transmitted malaria in the USA, click this link: Locally-transmitted malaria.
