The expansion of the tiger mosquito, a vector that can transmit diseases such as dengue, chikungunya, and Zika virus, poses a growing threat to global health. This study focuses on the entomological surveillance of Kastellorizo, a remote Greek island affected by its expansion. This research employs a multifaceted approach, combining KAP survey (knowledge, attitude, practices), mosquito collection using adult traps and human landing catches, and morphological and molecular identification methods.

- The study examined 3,661 individuals suspected of visceral leishmaniasis (VL) in Greece over a 16-year period (2005-2020) to analyze the seasonality, demographics, and genotypes of VL cases.
- Out of the cases analyzed, 219 were diagnosed as definite VL, predominantly affecting older adults (≥65 years) with symptoms like fever, splenomegaly, and hepatomegaly.
- The research identified the circulation of ITS type A as the genotypic type present in Greece's VL cases for the first time, also noting a seasonal pattern with peaks in February and June.
Usutu virus (USUV) is a mosquito-borne flavivirus originating from Africa, that belongs to the Japanese encephalitis virus (JEV) complex. In nature, USUV involves Culex spp. mosquitoes acting as vectors and birds as amplifying hosts.

- West Nile Virus (WNV) is a mosquito-borne virus that threatens public health in Europe, with increasing incidence rates observed in recent years.
- A study conducted in winter 2022 found WNV-positive Culex pipiens mosquitoes in Greece, indicating potential year-round circulation of the virus.
- The research highlights the importance of winter surveillance for mosquitoes in areas historically impacted by WNV to better manage outbreaks.
Article Synopsis
- * A study analyzed 124 malaria DNA samples from 2015-2019, revealing a diverse range of unique genetic strains, pointing to multiple importation events but limited local transmission.
- * Genotyping helps enhance malaria surveillance by identifying patterns of disease introduction and evaluating the success of control and elimination efforts in Greece.
