Abstract: Dengue virus is a single-stranded RNA virus that belongs to Flaviviridae family. This virus causes dengue fever which is transmitted by Aedes aegypti dan Aedes albopictus. There are four serotypes of dengue virus; all of them can cause dengue fever. Understanding the genomics of dengue virus is important for research and diagnostics. The genome of dengue virus is 11 kilo-base long. It consists of 5’-untranslated region (5’-UTR), three structural genes (coding capsid protein, pre-membrane/membrane, and envelope), seven non-structural genes (coding NS1, NS2A, NS2B, NS3, NS4A, NS4B, and NS5 proteins) and 3’-UTR. Non-structural genes are encoding proteins of viral RNA replication, interferon response, viral assembly and secretion, endoplasmic reticulum membrane invagination induction, immune-mediator induction, and RNA 5’-caping.Keywords: dengue virus, genome, structural genes, non-structural genes, untranslated region.Abstrak: Virus dengue merupakan virus RNA beruntai tunggal yang termasuk dalam famili Flaviviridae. Virus ini adalah penyebab penyakit demam berdarah dengue yang ditransmisikan melalui nyamuk Aedes aegypti dan Aedes albopictus. Ada empat serotipe virus dengue yang telah dikenal secara luas yang ada semuanya dapat menimbulkan penyakit demam berdarah. Pemahaman tentang genomik virus dengue sangat penting untuk pengembangan penelitian dan juga untuk keperluan diagnostik. Genom virus dengue memiliki panjang 11 kilo basa.

Dengue fever caused by dengue virus is a common tropical infection transmitted by the mosquitos Aedes aegypti and Aedes albopictus. Four strains of the genus flavivirus is responsible for the epidemics of varying severity. Hepatitis A caused by hepatitis A virus is spread by faecal-oral route. The culprit virus is a hepatovirus. Coinfection with dengue virus and hepatitis A virus is rare and is a diagnostic as well as management challenge to the medical professional. We report a patient who presented to us with dengue virus and hepatitis A virus coinfection.

Introducción. Aedes aegypti y Ae. albopictus son reconocidos vectores de arbovirus como los del dengue, la fiebre amarilla, el chikungunya y el Zika, en regiones tropicales y subtropicales del mundo. En Colombia, la distribución geográfica de Ae. albopictus ha sufrido un incremento y hoy incluye ciudades como Cali y Medellín. Hasta ahora, sin embargo, no se ha recabado información concluyente sobre su infección viral y su capacidad de transmisión a los humanos.Objetivo. Determinar la infección natural por dengue en ejemplares de Ae. albopictus recolectados en un área urbana de Medellín.Materiales y métodos. Se recolectaron individuos de Ae. albopictus en el campus de la Universidad Nacional de Colombia, sede Medellín. Se confirmó su clasificación taxonómica mediante el análisis del gen citocromo oxidasa I (COI), y se extrajo el ARN total para la identificación del virus del dengue y de los respectivos serotipos. La presencia del genotipo DENV se infirió mediante el análisis del gen NS3.Resultados. El análisis del COI corroboró el estatus taxonómico de Ae. albopictus. Uno de los mosquitos procesados fue positivo para DENV-2 y el análisis del NS3 mostró una gran similitud con el genotipo asiático-americano.Conclusión. Se reporta la infección con DENV-2 en Ae. albopictus en Medellín, Colombia. La presencia del genotipo asiático-americano en una zona urbana sugiere su posible circulación entre humanos y en Ae. albopictus, lo cual alerta sobre su eventual papel en la transmisión del DENV-2, y sobre la necesidad de incluir esta especie en la vigilancia entomológica en Colombia.

Dengue fever is a mosquito-borne viral illness that is quickly spreading over the globe, with significant death and morbidity rates. Dengue fever is an acute viral infection transmitted by Aedes mosquitos and caused by an RNA virus from the Flaviviridae family. The symptoms might vary from asymptomatic fever to life-threatening complications including hemorrhagic fever and shock. Although dengue virus infections are normally self-limiting, the disease has become a public health concern in tropical and subtropical countries. Dengue fever is a major public health concern owing to its rapid worldwide spread, and its burdens are now unmet due to a lack of accurate therapy and a simple diagnostic approach for the early stages of illness.

One of vector borne deseases which still remains a health problem in Indonesia is dengue fever (DBD). This desease is caused by dengue virus transmitted by Aedes aegypti mosquitoes. One of cities which is endemic for DBD in 2014 was Banda Aceh. The indicator for DBD endemic is based on entomology index. One of entomology index to be measured is the number of mosquito larvae-free. To know the status of mosquito larvae-free number in Banda Aceh, a suvey has been conducted in three subdistricts within Banda Aceh city, namely Banda Raya (Lamlagang village), Ulee Kareng (Ceurih village), and Baiturrahman (Peuniti village). A survey was conducted in 100 houses of every subdistrict. The total of 300 houses were investigated. From 300 houses investigated, there were 158 houses were positively had mosquito larvae. From 860 containers that were found and checked in those three subdistricts, it was found that there were 235 containers were positively contained mosquito larvae. The container which contained mosquito larvae dominantly was bathups inside the houses, there were 48,22% of larvae and 60,47% of pupas. The results showed that the number of mosquito larvae-free for Banda aceh was 47,33% which indicated that it was still below the number of national larvae-free that is > 95%. Therefore, Banda Aceh is still in a high risk of DBD transmission in the future.

The Family

Flaviviruses are largely transmitted to humans by their arthropod vectors such as mosquitoes or ticks. The dengue virus (DENV) is one of the members of the family Flaviviridae and is the causative agent of dengue fever. In the mosquito vector, DENV enters through viremic blood meal and replicates in the mid-gut. Newly formed virion particles circulate to various mosquito organs and get transmitted to the next host in subsequent bites. Aedes aegypti and Aedes albopictus have intricate immune control to allow DENV production at a sub-pathogenic level. In the mosquito, antimicrobial peptides (AMP) and RNA inference (RNAi) are the two main antiviral strategies used against DENV. Apart from innate immunity, mosquito resident microbes play a significant role in modulating DENV replication. In this review, we discuss different immune mechanisms and preventive strategies that act against DENV in two of its vectors: Aedes aegypti and Aedes albopictus.

Abstract Our article documents the presence of Aedes albopictus (Skuse) from urban and rural locations in the lower Himalaya Mountains, northern Pakistan. Larvae were collected from graveyards, junkyards, plant nurseries, parks, and houses. Used tires, bird drinking pots, and water storage containers were the most common containers used by this mosquito. In the absence of Aedes aegypti (L.) (Diptera: Culicidae), Ae. albopictus appears to be the primary vector of recent dengue virus outbreaks.

Acute Viral Infection

Dengue is a mosquito-borne acute viral infection that can develop into a potentially lethal complication known as severe dengue. It is endemic in more than 100 tropical and subtropical countries where the mosquito vectors, predominantly Aedes aegypti and Aedes albopictus, are found. Non-immune travellers are at risk of infection and with the rise in international travel and the availability of cheap holiday packages to endemic countries, many of which are popular tourist destinations, there has been a significant increase in spread of dengue viruses.
