The "VectoHantivirus-ampli" test system based on rtPCR was shown as fitting the detection of virus RNA in blood samples of patients with hemorrhagic fever with renal syndrome (HFRS) made at early stages and no later than 7 days from the disease onset. A sequence analysis of viral nucleotide sequences of PCR products produced by the test-system ensured the identification of Hantaviruses (pathogens of HFRS). Two genetic variants of Puumula virus were shown to circulate in the territory of the Bashkortostan Republic; they differ by 10.0-13.8%, one of them is absolutely new. The Hantan virus FE genetic variant was detected in the studied samples from the Khabarovsk Territory.

Due to their widespread geographic distribution and frequent outbreaks, mosquito-borne flaviviruses, such as DENV (DENV), Zika virus (ZIKV), Japanese encephalitis virus (JEV), yellow fever virus (YFV), and West Nile virus (WNV), are considered significant global public health threats and contribute to dramatic socioeconomic imbalances worldwide. The global prevalence of these viruses is largely driven by extensive international travels and ecological disruptions that create favorable conditions for the breeding of and species, the mosquito vectors responsible for the spread of these pathogens. Currently, vaccines are available for only DENV, YFV, and JEV, but these face several challenges, including safety concerns, lengthy production processes, and logistical difficulties in distribution, especially in resource-limited regions, highlighting the urgent need for innovative vaccine approaches.

Background: Yunnan Province, located in the southwestern part of China and neighboring endemic dengue regions of Southeast Asia, has experienced annual autochthonous outbreaks of dengue fever from 2013 to 2023. This study examines the epidemiological and spatiotemporal clustering characteristics of dengue within the province.
Methods: Descriptive epidemiological methods were used to analyse outbreak characteristics.

The global burden of dengue disease is escalating under the influence of climate change, with India contributing a third of the total. The non-linearity and regional heterogeneity inherent in the climate-dengue relationship and the lack of consistent data makes it difficult to make useful predictions for effective disease prevention. The current study investigates these non-linear climate-dengue links in Pune, a dengue hotspot region in India with a monsoonal climate and presents a model framework for predicting both the near-term and future dengue mortalities.

Dengue hemorrhagic fever (DHF) typically presents with various bleeding manifestations such as epistaxis, gum bleeding, and gastrointestinal bleeding. However, spontaneous large muscle hematoma formation is a rare complication. This case report discusses a patient with DHF who developed bilateral psoas muscle hematomas, a very uncommon presentation.
