BACKGROUNDS OBJECTIVES: Dengue fever, transmitted by Aedes mosquitoes, is a significant public health concern in Nepal. An extensive Knowledge, Attitude, and Practice (KAP) survey related to Aedes mosquitoes and the prevention of dengue was conducted along the route from Matihani (62 m asl) to Kalinchok (3840 m asl) in central Nepal. This research examined residents' awareness of Aedes mosquitoes and the diseases they transmit, aiming to support the World Health Organization's national and global fight against mosquito-borne diseases...

BACKGROUND OBJECTIVES: Biological approaches for vector mosquito control such as sterile insect technique (SIT) requires sterilization of male mosquitoes through specific radiation doses for sterility induction in males. Under the SIT program, the males used must be compatible with the wild males in vigor, flight and selection of mate. Much of this potential is determined by the diet provided in the larval stages and optimizing the irradiation doses that cause complete sterility but have very minimal effect on the lives of irradiated males...

BACKGROUND OBJECTIVES: Lyme disease is a multisystemic disease caused by the bacteria in the Borrelia burgdorferi sensu lato complex, which is transmitted by ticks of Ixodes genus. Although there are seroprevalence studies and case reports of Lyme disease from various regions in Turkey, there is no widespread epidemiological research. This study aimed to determine the frequency of Lyme disease in the cases followed-up after tick contact and to examine the isolated ticks to reveal tick population from Bolu province...

BACKGROUND AND OBJECTIVES: RNA viruses are complex pathogens in terms of their genetic makeup, mutation frequency, and transmission modes. They contain the RNA helicase enzyme, which plays a crucial role in the viral genome replication process. This work aims to develop and screen a potential molecule that could function as a dengue virus (DENV) RNA helicase inhibitor. METHODS: The present study was performed by taking 26 potential derivatives of gedunin phytochemicals from the PubChem database as ligands...

BACKGROUND OBJECTIVES: Mosquito-borne diseases are increasing problems in various parts of the world, causing high mortality and morbidity for humans. This study was done to assess the vector protection measures taken by rural BPL (below-poverty-line) families, and to assess the awareness about vector-borne diseases along with Total Sanitation Campaign (TSC) in rural BPL families. METHODS: A cross-sectional study was conducted in rural areas, which won Nirmal Gram Puraskar Award, among 96 BPL families for a period of three months...

Dengue fever, caused by the dengue virus transmitted by mosquitoes, usually manifests as flu-like symptoms and is a prevalent tropical illness. However, there are rare cases where the infection takes an unusual course, resulting in severe complications like dengue encephalitis. This case report delineates an occurrence of dengue encephalitis in a patient from Sri Lanka. This work provides insights into the clinical presentation, diagnostic difficulties, and treatment approaches linked to this uncommon manifestation of dengue fever...

Vector-borne diseases exert immense health burdens worldwide. Malaria alone causes over 200 million cases and 600,000 deaths annually. Transmission involves complex drivers requiring examination beyond entomological factors. A systematic literature search across databases identified relevant studies on vector-borne disease determinants published in the last two decades, with priority given to rigorous designs like longitudinal analyses, reviews, and meta-analyses from diverse epidemic regions, allowing narrative synthesis of key determinants, relationships, and gaps...

BACKGROUND OBJECTIVES: Dengue fever is a mosquito-borne illness that affects millions of people worldwide every year. With no vaccination available, early detection and treatment is critical. One-hundred-twelve countries in the world pose a risk to travelers, particularly in metropolitan areas. Laboratory diagnoses vary according to objectives, resources, and schedule, with sensitivity and specificity must be balanced for effective testing. METHODS: The current work is a cross-sectional diagnostic study and samples from suspected patients of dengue was collected from May 15 to November 15 2023 and transported to laboratory, and RT-PCR and Dengue Duo Rapid test diagnosis techniques were used on 48 clinical samples included in this study...

BACKGROUND: Dengue poses a considerable public health threat in Saudi Arabia, with escalating outbreaks in Jazan, where seasonal rains create ideal mosquito breeding conditions. Elucidating local epidemiological dynamics is imperative to strengthen evidence-based prevention policies. This study analyzed the spatiotemporal, demographic, and meteorological patterns of dengue in Jazan from 2015-2020. METHODS: This retrospective cross-sectional study utilized surveillance records for 3427 confirmed dengue cases...

BACKGROUND OBJECTIVES: The persistent threat of drug resistant malaria demands new cures. Low prevalence of malaria in the Indian state of Kerala compared with other proximal states made us explore if there is any traditional practice in Kerala which may confer protection against malaria. In this context, our attention was drawn to 'Pathimugam' i.e., Ceasalpinia sappan whose heartwood is used to prepare a red aqueous extract which is a uniquely popular drink in Kerala. METHODS: Aqueous and methanolic extracts of various organs of C...

BACKGROUND OBJECTIVES: Anopheles stephensi is responsible for the transmission of malaria in urban areas. Vector competence of An. stephensi from a non-malarious (Coimbatore) and highly malarious (Chennai) urban areas in Tamil Nadu state of India, was investigated to find the reason for non-transmission of malaria in Coimbatore. METHODS: Vector competence (susceptibility/refractoriness) of An. stephensi mosquitoes from Chennai (malarious) and Coimbatore (non-malarious) to Plasmodium vivax (Chennai) was investigated...

BACKGROUND OBJECTIVES: At present the use of synthetic pesticides to manage insects and other arthropods creates a number of issues that are related to the environment and public health. The goal of the present study was to find the repellent activity of Vitex negundo and Curcuma longa herbal extract against the wild species Simulium (blackfly) bite. METHODS: We have studied Simulium biting behavior and tested the repellency of herbal extract obtained from Vitex negundo L...

Vector transmitted diseases are accountable for more than 17% of all infectious disease cases worldwide according to World Health Organization. Insect vectors play a key role in transmitting diseases and loss of lives. Modified and advanced vector control strategies with chemical insecticides are needed as vectors are resistant to a particular insecticide. Moreover, chemical control is cost-inductive and may give rise to health issues. In this review, bioacoustics have been narrated as a novel technology for eco-friendly and cost-effective control of insect vectors...

Malaria is a global health problem that causes 1.5-2.7 million deaths worldwide each year. Resistance to antimalarial drugs in malaria parasites and to insecticides in vectors is one of the most serious issues in the fight against the disease. Moreover, the lack of an effective vaccine against malaria is still a major concern. Recent developments in nanotechnology have resulted in new prospects for the fight against malaria, especially by obtaining metal nanoparticles (NPs) that are less toxic, highly biocompatible, environmentally friendly, and less expensive...

BACKGROUND OBJECTIVES: Malaria remains a complex challenge in India due to its diverse epidemiology, multi-ethnic population, and multiplicity of malaria vectors. While progress has been made in reducing malaria nationally, persistent pockets hinder elimination efforts. These challenges include hidden reservoirs, inadequate healthcare, suboptimal surveillance, non-compliance, and subclinical infections. Shortage of grassroot level and primary care health staff, transportation issues and general inaccessibility and unavailability of healthcare services are additional challenges...
