Serological Determination of West Nile Virus in Domestic Birds from Rapa Nui, Chile

Vector Borne Zoonotic Dis. 2023 Jan 4. doi: 10.1089/vbz.2022.0054. Online ahead of print.


Background: Flaviviruses are agents with high zoonotic potential of importance to human health. They are transmitted by mosquitoes of the Culicidae family, and birds act as host-amplifiers. Birds, mammals, and humans are susceptible hosts to infection. Methods: In this study, West Nile virus (WNV), flavivirus, infection was studied in 37 serum samples from 22 hens on Easter Island, Chile. Results: WNV was detected by ELISA (ID Screen® West Nile Competition Multi-Species). We report absence of antibodies to WNV, and to related viruses of the Japanese Encephalitis Virus serocomplex, and, therefore, absence of infection across the sample. Conclusion: This is the first evaluation of its type carried out in Chile, and represents a positive result for public health at Easter Island.
