The dengue virus is transmitted to humans via the bite of a mosquito. The principle mosquito species is known as Aedes aegypti. This mosquito is found all over the world‚ and‚ throughout time‚ became adapted to urban environments. For example‚ the mosquito evolved so as to be capable of living year round in moist storage containers‚ rather than relying on the seasonal patterns of rainfall. Another species‚ Aedes albopictus (the "Tiger mosquito")‚ is widespread throughout Asia. Both mosquitoes are

It is a mosquito-borne‚ single positive-stranded RNA virus of the family Flaviviridae; genus Flavivirus. Its genome is about 11000 bases that codes for three structural proteins‚ capsid protein C‚ membrane protein M‚ envelope protein E; seven nonstructural proteins‚ NS1‚ NS2a‚ NS2b‚ NS3‚ NS4a‚ NS4b‚ NS5; and short non-coding

Menace of Dengue Dengue is an arbovirus disease caused by any one of four closely related viruses that do not provide cross-protective immunity; a person can be infected as many as four times‚ once with each serotype. Dengue viruses are transmitted from person to person by the Aedes aegypti mosquito in the domestic environment. Periodic epidemics have occurred in the Western Hemisphere for over 200 years. In the past 20 years‚ however‚ dengue transmission and frequency of epidemics have increased

Dengue virus is an epidemic facing many Asian countries. Although the current topic of discussion among health professionals is a possible outbreak of avian flu among humans‚ the dengue virus kills hundreds every year in the same region (ONE). This epidemic is not one that faces easy fixes‚ in fact there is no vaccine for the dengue virus. In this paper I will discuss and explain how the dengue virus poses a great threat to the region and how it plagues the lives of thousands of people in Asia.

Bedeviled By Dengue Dengue is a mosquito-borne infection found in tropical and sub-tropical regions around the world. In recent years‚ transmission has increased predominantly in urban and semi-urban areas and has become a major international public health concern. Severe dengue (also known as Dengue Haemorrhagic Fever) was first recognized in the 1950s during dengue epidemics in the Philippines and Thailand. Today‚ severe dengue affects most Asian and Latin American countries and has become a

Dengue fever is a disease caused by one of a number of viruses that are carried by mosquitoes. These mosquitoes then transmit the virus to humans. The virus that causes dengue fever is called an arbovirus‚ which stands for arthropod-borne virus. Mosquitoes are a type of arthropod. In a number of regions‚ mosquitoes carry this virus and are responsible for passing it along to humans. These regions include the Middle East‚ the far East‚ Africa‚ and the Caribbean Islands. In these locations‚ the
