Genomics-based timely detection of dengue virus type I genotypes I and V in Uruguay.

Laboratorio de Virus Emergentes/reemergentes. Unidad de Virología, Departamento de Laboratorios de Salud Pública, Portugal.
This study details a genomics-based approach for the early detection of mosquito-borne pathogens, marked by Uruguay's first ever complete genomic sequencing of Dengue Virus type I genotypes I and V. This pioneering effort has facilitated the prompt identification of these genotypes within the country, enabling Uruguayan public health authorities to develop timely and effective response strategies. Further integrated into this approach is a climate-driven suitability measure, closely associated with Dengue case reports and indicative of the local climate's role in the virus's transmission in the country within the changing climate context.

The standard dengue virus (DENV) neutralization assay inconsistently predicts dengue protection. We compare how IgG ELISA, envelope domain III (EDIII), or non-structural protein 1 (NS1) binding antibodies, and titers from plaque reduction neutralization tests (PRNTs) using standard and mature viruses are associated with dengue. The ELISA measures IgG antibodies that bind to inactivated DENV1-4.

Dengue fever is a vector-borne, acute, febrile, and self-limiting systemic viral infection that affects tropical and subtropical regions, including Pakistan. Karachi has a significant burden of Aedes aegypti and Aedes albopictus due to suitable breeding sites, weather, and rapid and unplanned urbanization of squatter areas. The country has limited surveillance studies on circulating serotypes of the dengue virus and the patient's clinical features evolving over temporal changes.

Background & objectives Dengue virus causes frequent outbreaks and epidemics with high morbidity and mortality. It is important to monitor the trends of the dengue virus and its serotypes. We carried out the present work to study the prevalence of the dengue virus and its serotypes in clinically suspected cases of dengue in Rajasthan.

Dengue flavivirus (DENV) is the virus that causes dengue, one of the most dangerous and common viral diseases in humans that are carried by mosquitoes and can lead to fatalities. Every year, there are over 400 million cases of dengue fever worldwide, and 22,000 fatalities. It has been documented in tropical and subtropical climates in over 100 nations.
