Department of Entomology; The Global Change Center at Virginia Tech; and the Center for Emerging Zoonotic & Arthropod-Borne Pathogens (CeZAP), Virginia Polytechnic Institute and State University, Blacksburg, VA 24061, USA.
Rift Valley fever virus (RVFV) is an emerging mosquito-borne arbovirus of One Health importance that caused two large outbreaks in Rwanda in 2018 and 2022. Information on vector species with a role in RVFV eco-epidemiology in Rwanda is scarce. Here we sought to identify potential mosquito vectors of RVFV in Rwanda, their distribution and abundance, as well as their infection status.

Current arbovirus surveillance strategies in Australia involve mosquito collection, species identification, and virus detection. These processes are labour-intensive, expensive, and time-consuming and can lead to delays in reporting. Mosquito excreta has been proposed as an alternative sample type to whole mosquito collection, with potential to streamline the virus surveillance pipeline.

College of Life Science and Technology, Xinjiang University, Urumqi, 830017, China.
Background: Tamdy virus (TAMV) was first isolated in Uzbekistan and Turkmenistan. In 2018, it was found in China, marking its entry into the molecular research era. TAMV is linked to febrile diseases, but its epidemiology and spillover risks are poorly understood, necessitating urgent molecular research and detection method development.

According to WHO, dengue fever (DF) is currently endemic to more than 100 countries in various regions of Africa, America, and Asia; outbreaks have been reported in Europe. In the Russian Federation, there is a much smaller proportion of children among those infected due to the imported nature of the infection. We described a clinical case of imported dengue fever in an adolescent girl in Moscow after a 5-day vacation.

Institut Pasteur de Dakar, Immunophysiopathology and Infectious Diseases Department, G4-Malaria Experimental Genetic Approaches and Vaccines Unit, Dakar, Senegal.
Background: Since 2006, artemisinin-based combination therapies (ACTs) have been introduced in Senegal in response to chloroquine resistance (CQ-R) and have shown high efficacy against Plasmodium falciparum. However, the detection of the PfKelch13R515K mutation in Kaolack, which confers artemisinin resistance in vitro, highlights the urgency of strengthening antimalarial drug surveillance to achieve malaria elimination by 2030.
Objective: To assess the proportion of P.
