Increased risk of dengue virus (DENV) infections
On June 25, 2024, CDC issued a Health Alert Network (HAN) message about an increased risk of dengue virus (DENV) infections in the United States in 2024. The CDC is actively implementing several strategies to address the increase in cases of dengue including expanding laboratory capacity to improve laboratory testing approaches. Information about clinical testing guidance for dengue and instructions for submitting specimens for dengue virus tests is available.
How to report dengue cases
