Optimal control of a dengue epidemic model with vaccination [PDF]

, 2011
We present a SIR+ASI epidemic model to describe the interaction between human and dengue fever mosquito populations. A control strategy in the form of vaccination, to decrease the number of infected individuals, is used.

Analyses of clinical and laboratory characteristics of dengue adults at their hospital presentations based on the World Health Organization clinical-phase framework: Emphasizing risk of severe dengue in the elderly

Journal of Microbiology, Immunology and Infection, 2018
Background/Purpose: Dengue clinically dynamically changes over time; the World Health Organization (WHO) dengue classification framework proposed 3 dengue clinical phases—febrile (days 1–3), critical (days 4–6) and recovery (days ≥7) phases.

Biochemical Responses of Anopheles spp. Larvae to a Novel Brazilian BR101 Bacillus thuringiensis var. israelensis Formulation: Oxidative Stress, Detoxification Enzymes, and Safety for Nontarget Notonectidae and Gerridae Aquatic Insects

Chemistry &Biodiversity, EarlyView.
Bti BR101 exhibits strong larvicidal activity against Anopheles larvae spp., with dose‐dependent mortality and LC50 of 3.13 µg/mL. Bti increases ROS, lipid and protein oxidation, and activates antioxidant enzymes (SOD, CAT, GPx) and detoxification pathways (MFO and esterases), indicating moderate oxidative stress.

Immunogenicity of NS4b dengue 3 virus mimotope presented to the immune system as multiple antigen peptide system [PDF]

, 2013
The availability of random peptide libraries displayed on bacteriophage (RPL) has provided a powerful tool for selecting sequences that mimic binding properties of natural antigen epitopes (mimotopes). These mimotopes can be used for vaccine design, drug

Cardiac tamponade in a patient with severe dengue fever

Revista da Sociedade Brasileira de Medicina Tropical
A 26-year-old postpartum female presented with symptoms characteristic of dengue fever on the 16th day of puerperium. On the third day of the illness, the patient presented a clinical picture consistent with shock. Tests determined primary infection with

A clustered regularly interspaced palindromic repeat‐Cas12a‐based assay for rapid dengue virus monitoring in mosquito and clinical samples facilitating global collaborative surveillance and risk assessment to block dengue spreading

Interdisciplinary Medicine, EarlyView.
The RAA‐Cas12a assay outperforms real‐time PCR in sensitivity (92.3%) while matching its specificity (100%) for dengue virus detection in clinical samples. It effectively identifies DENV in mosquitoes, with field data correlating to local outbreaks. This rapid, simple, and precise method serves as an early warning tool for dengue management.

Dynamics of Dengue epidemics using optimal control [PDF]

, 2010
We present an application of optimal control theory to Dengue epidemics. This epidemiologic disease is an important theme in tropical countries due to the growing number of infected individuals.

Enhancement of Epidemiological Models for Dengue Fever Based on Twitter Data

, 2017
Epidemiological early warning systems for dengue fever rely on up-to-date epidemiological data to forecast future incidence. However, epidemiological data typically requires time to be available, due to the application of time-consuming laboratorial ...
