  • Essay / Overview of Dengue Virus

    Dengue virus (DENV) is one of the life-threatening diseases caused by parasites that transfer infectious agents from one living organism to another, causing serious illness. It has become the most endemic tropical disease in the Philippines, especially during the rainy season, June to August, when optimal transmission of pathogens occurs. According to the Department of Health (DOH), the country was ranked fourth in terms of dengue prevalence in all of Southeast Asia, with over 117,065 cases between 2008 and 2012. Looking back, it was noted that the highest accidental rate of dengue occurred in Manila with more than 60.9 cases per 100,000 inhabitants. This is because as time passes, there is rapid urbanization and more waste is disposed of every time a person consumes a good. Say no to plagiarism.

Atif Abbasi (2016) describes that the dengue virus ranges from the appearance of an ordinary high body temperature to a very dangerous capillary leak, also called Clarkson's disease. When fluids and proteins leak from the bloodstream into a circulatory system, organs such as the kidneys, liver and brain can be deprived of oxygen and certain nutrients, leading to a disruption in their functioning. It stops organs from functioning, which can lead to death. The World Health Organization (2018) also describes that dengue virus is a fervent infection with approximately 2.5 billion people at risk in developing and developed countries. Female mosquitoes, including the yellow fever mosquito or Aedes Aegypti and the forest mosquito or Aedes Albopictus, are well-known parasites of the Kingdom Animalia and the Family Culicidae. These mosquito species are the main vectors of dengue virus, chikungunya virus, yellow fever virus and Zika infection. However, male mosquitoes of all species live only on fruit. The World Health Organization (2018) also states that these female mosquitoes are active depending on daily temperature levels. During the colder seasons, some mosquitoes die and others hibernate. When the temperature reaches 50 degrees Fahrenheit, these mosquitoes will be active and begin hatching their eggs, which will eventually increase their population. It lays its eggs on rainwater stored in containers and tires, or in polluted and poorly managed rivers. These areas will attract large numbers of mosquito species and will likely provide the safest and most dangerous refuge for people of all ages who are near the area. According to Faiman et. al. (2014), the evolution of mosquitoes depends on water. Anything that contains water can provide a possible habitat for mosquitoes, stagnant or not, small or huge. So, mosquitoes can produce as long as water is present. Beckford (2017) states that these aquatic mosquitoes are called blind mosquitoes. These are mainly linked to poor water quality and have a considerable number of populations in natural and artificial water bodies. Their eggs are attached to the shrub on the water surface and can last up to two or seven weeks before hatching. Therefore, the pupal stage will take approximately 3 days. Although Swift (2017) states that mosquitoes do not play a significant role,.
