Malaria is listed as a "rare disease" by the Office of Rare Diseases (ORD) of the National Institutes of Health (NIH). This means that Malaria, or a subtype of Malaria, affects less than 200,000 people in the US population.
Ophanet, who are a consortium of European partners, currently defines a condition rare when if affects 1 person per 2,000. They list Malaria as a "rare disease". More information about Malaria is available from Orphanet

In the United States, approximately 1,000 cases are reported annually, which researchers estimate represent only 25 to 50 percent of actual cases. (Source: excerpt from Microbes in Sickness and in Health -- Publications, National Institute of Allergy and Infectious Diseases: NIAID)
Each year, 300 to 500 million people develop malaria and 1.5 to 3 million–mostly children–die, according to the World Health Organization (WHO). (Source: excerpt from Malaria, NIAID Fact Sheet: NIAID)
Although the disease was eradicated in the United States in the 1940s, about 1,000-1,400 cases of malaria are reported to CDC each year; almost all acquired during international travel. Over 75% of these cases are associated with failure to use recommended chemoprophylaxis. (Source: excerpt from Facts About Transfusion-Transmitted Malaria: CDC-OC)
Each year in the United States, several cases (< 10) of malaria are acquired stateside, by congenital transmission, local mosquito-borne transmission, or by blood transfusion or organ transplantation. On average, 2-3 cases of transmission occur by blood transfusion annually. (Source: excerpt from Facts About Transfusion-Transmitted Malaria: CDC-OC)
300 to 500 million people develop malaria
The following statistics relate to the incidence of Malaria:
The following statistics relate to deaths and Malaria:
The term 'prevalence' of Malaria usually refers to the estimated population
of people who are managing Malaria at any given time.
The term 'incidence' of Malaria refers to the annual diagnosis rate,
or the number of new cases of Malaria diagnosed each year.
Hence, these two statistics types can differ:
a short-lived disease like flu can have high annual incidence but low prevalence,
but a life-long disease like diabetes has a low annual incidence but high prevalence.
For more information see about prevalence and incidence statistics.
