Autochthonous Dengue Fever in 2 Patients, Rome, Italy

Serena Vita et al. Emerg Infect Dis. 2024 Jan.

Abstract

Since August 2023, outbreaks of dengue virus (DENV) infection have occurred in Italy. We report 2 autochthonous case-patients and their extended follow-up. Despite persistent DENV detected in blood by PCR, results for antigenomic DENV RNA were negative after day 5, suggesting that a 5-day isolation period is adequate to avoid secondary cases.

Keywords: DENV; Italy; PCR; antigenomic DENV RNA; autochthonous cases; dengue; dengue fever; dengue virus; viruses; zoonoses.
