Severe malaria in immigrant population: a retrospective review

Area of Science:

• * Infectious Diseases
• * Public Health
• * Epidemiology

Background:

• * Imported malaria presents a significant and increasing medical challenge in the United States.
• * Foreign-born immigrants visiting malaria-endemic countries often forgo malaria prophylaxis due to a misconception of immunity.
• * This contributes to a substantial proportion of imported malaria cases.

Purpose of the Study:

• * To review the epidemiology and clinical presentation of malaria in a community hospital setting.
• * To determine the rate of malaria prophylaxis use among at-risk populations.
• * To delineate the incidence of severe malaria within this demographic.

Main Methods:

• * A retrospective chart review was conducted.
• * Data were collected from forty patients diagnosed with malaria between 1997 and 2007.
• * The study focused on patients at a teaching hospital in Newark, NJ, with a large immigrant population.

Main Results:

• * Ninety percent of malaria cases involved patients born in malaria-endemic areas (MEAs).
• * Eighty-five percent acquired malaria while visiting the African subcontinent.
• * The overall malaria prophylaxis rate was low (12%).
• * Plasmodium falciparum was the most common species.
• * Twenty-five percent of cases presented as severe malaria, exclusively in foreign-born individuals visiting endemic regions.

Conclusions:

• * Malaria remains a significant health challenge for immigrants traveling to their countries of origin.
• * The low uptake of malaria prophylaxis is a major concern, linked to high rates of severe disease.
• * Primary care physicians are crucial for providing pre-travel advice to prevent malaria complications.
