Locally Acquired Malaria Cases Identified in the United States

The Centers for Disease Control and Prevention (CDC) is issuing this Health Alert Network (HAN) Health Advisory to share information and notify clinicians, public health authorities, and the public about:

1. Identification of locally acquired malaria cases (P. vivax) in two U.S. states (Florida [4] and Texas [1]) within the last 2 months,
2. Concern for a potential rise in imported malaria cases associated with increased international travel in summer 2023, and
3. Need to plan for rapid access to IV artesunate, which is the first-line treatment for severe malaria in the United States.
