An outbreak of dengue fever occurred among employees of a recreation club in Bangladesh. Occupational transmission was characterized by a 12% attack rate, no dengue among family contacts, and Aedes vectors in club areas. Early recognition of the outbreak likely limited its impact.

Dengue is a mosquito-borne disease caused by dengue virus (DENV) infection, which remains a major public health concern worldwide owing to the lack of specific treatments or antiviral drugs available. This study investigated the potential repurposing of domperidone, an antiemetic and gastrokinetic agent, to control DENV infection. Domperidone was identified by pharmacophore-based virtual screening as a small molecule that can bind to both the viral envelope (E) and the nonstructural protein 1 (NS1) of DENV.

Background: During the 2023-dengue outbreak in Bangladesh, a diagnostic evaluation study was conducted to investigate concurrent Zika virus (ZIKV) and dengue virus (DENV) transmission in Dhaka in 2023.
Aims: The study explored to simultaneously detect the presence of ZIKV, DENV, and/or CHIKV while considering relevant clinical and epidemiological risk factors, using a real-time multiplex RT-PCR system. Following this, it was planned to sequence the selected samples to identify genetic variations of the ZIKV infections within the population.

Dengue is the most common arboviral disease globally. It is caused by four distinct but closely related Dengue viruses (DENV-1, -2, -3, and - 4) transmitted through bites of infected Aedes species mosquito vectors. In the last 50 years, incidence has increased 30-fold with increasing geographic expansion to new countries.

Melioidosis is a disease endemic to India but often goes unrecognized, leading to considerable illness and death. We present the case of a 31-year-old man who had a fever of unknown origin, abnormal renal and liver function tests, and negative tests for dengue, typhoid, leptospirosis, and scrub typhus. Imaging revealed multiple splenic infarcts.

This mini-review examines the strategy of combining viral protein sequence conservation with drug-binding potential to identify novel antiviral targets, focusing on internal proteins of influenza A and other RNA viruses. The importance of combating viral genetic variability and reducing the likelihood of resistance development is emphasised in the context of sequence redundancy in viral datasets. It covers recent structural and functional updates, as well as drug targeting efforts for three internal influenza A viral proteins: Basic Polymerase 2, Nuclear Export Protein, and Nucleoprotein.
