[Re-emergence of Venezuelan equine encephalitis virus in French Guiana. Apropos of 1 confirmed case].

The research discusses the reappearance of Venezuelan equine encephalitis (VEE) virus in French Guiana, focusing on a case study of a young patient who developed severe symptoms and sadly passed away from the disease, demonstrating the need for ongoing surveillance to manage outbreaks of infectious diseases like VEE.

Overview of Venezuelan equine encephalitis (VEE)

• VEE is a disease predominantly transmitted by mosquitoes
• VEE primarily affects equine species (horses, donkeys, zebras, etc.) but can also infect humans
• There are two main types of the virus – enzootic and epizootic. The former usually causes infrequent diseases in humans and is not connected with disease in equines, and the latter is associated with large-scale illness and mortality in equine species.

Introduction of VEE in French Guiana

• The researchers present the first documented case of VEE in French Guiana.
• The patient was a young individual who came down with encephalitis, intersitial pneumonia, and acute liver failure – all critical conditions subsumed under VEE.
• The patient’s condition worsened rapidly, leading to their death within five days from multiple organ dysfunction syndrome, in spite of adequate symptomatic treatment.

Diagnosis and Significance of the Findings

• The diagnosis was established through virological testing, with the VEE virus found in the patient’s blood sample.
• This investigation provides a vivid example of how infectious diseases can re-emerge and serve as a reminder of our susceptibility to them. It stresses the importance of an active surveillance system in monitoring and managing such diseases.
