Dengue Case Study
INTRODUCTION

Dengue Fever is caused by one of the four closely related, but antigenically distinct, virus serotypes Dengue type 1, Dengue type 2, Dengue type 3, and Dengue type 4 of the genus Flavivirus and Chikungunya virus. Infection with one of these serotype provides immunity to only that serotype of life, to a person living in a Dengue-endemic area can have more than one Dengue infection during their lifetime. Dengue fever through the four different Dengue serotypes are maintained in the cycle which involves humans and Aedes aegypti or Aedes albopictus mosquito through the transmission of the viruses to humans by the bite of an infected mosquito. The mosquito becomes infected with the Dengue virus when it bites a person who has Dengue and after a week it can transmit the virus while biting a healthy person. Dengue cannot be transmitted or directly spread from person to person. Aedes aegypti is the most common aedes specie which is a domestic, day-biting mosquito that prefers to feed on humans.

Intubation Period: Uncertain. Probably 6 days to 10 days

Period of Communicability: Unknown. Presumed to be on the 1st week of illness when virus is still present in the blood

Clinical Manifestations:

First 4 days:
>febrile or invasive stage --- starts abruptly as high fever, abdominal pain and headache; later flushing which may be accompanied by vomiting, conjunctival infection and epistaxis
4th to 7th day:
>toxic or hemorrhagic stage --- lowering of temperature, severe abdominal pain, vomiting and frequent bleeding from GIT in the form of melena; unstable BP, narrow pulse pressure and shock; death may occur; vasomotor collapse
7th to 10th day:
>convalescent or recovery stage --- generalized flushing with intervening areas of blanching appetite regained and blood pressure already stable

Mode of Transmission:

Dengue viruses are transmitted to humans through the infective bites of female Aedes mosquito. Mosquitoes generally acquire virus while

    Yellow fever is found simply from parts of South America and Africa. This disease can only be carried by the female mosquitoes. There are two different cycles of the yellow fever: jungle yellow fever and urban yellow fever. Jungle yellow fever is primarily a sickness of monkeys. People can catch this disease by setting themselves in the central point of this innate cycle and are bitten by the mosquitoes that have been tainted by the monkeys. Jungle yellow fever is uncommon and only occurs generally to people who work in the jungle often. Urban yellow fever disease is a sickness of humans. It’s a spread from infected mosquitoes to other human beings. The urban yellow fever is the basis of most of the yellow fever epidemics and outbursts. Aedes aegypti is the type of mosquito that usually carries the yellow fever from one human to another. These types of mosquitoes breed close to human residences, like flower pots, useless tires, oil drums, and wet storage containers. This urban disease caused many mishaps to Napoleon’s troops at Haiti.…

    West Nile Virus

    The number of interactions between birds and mosquitos is vast. If a bird is carrying the virus and has been bitten, the mosquito has now been infected. Once the host, the mosquito, has been infected the virus then travels throughout the host’s body until it ends up in the salivary glands. Humans become infected because during the warmer months, such as summer, mosquitos are more prevalent and humans are at a higher risk of being bitten. A mosquito bite consists of saliva entering into human tissues and blood stream, thus infecting a new host. Compared to mosquitos, humans are not highly suitable hosts for the virus to survive. The only possible way for humans to infect each other would be through anything to do with donating human tissues, such as organs, or anything containing blood. Although only 25% of people will experience symptoms of the virus it can affect humans in many different scenarios. These include damage to the central nervous system or fevers that may cause hemorrhages. One type of fever humans can get is known as West Nile fever. Complications such as these occur due to the fact that West Nile virus is a part of the Flaviviridae category of viruses. Neurotropic viruses,…

    Dengue viruses are transmitted to humans (host) through the bites of the female striped Aedes aegypti mosquito (vector). This variety of mosquito breeds easily during the rainy seasons but can flourish in peridomestic fresh water, e.g. water that is stored in plastic bags, cans, flowerpots and old tires. The dengue virus is transmitted to its host during probing and blood feeding. The mosquito may carry the virus from one host to another host and the mosquito is most active in the early morning and later afternoon. A mosquito bite can cause the disease. Incubation period occurs when the viruses has been transmitted to the human host. The period ranges from 3 to 15 days (usually lasting for 5-8 days) before the characteristics of dengue appear. During incubation…

    The main and only way chikungunya can be transmitted is through mosquito’s bites. The mosquitoes that cause chikungunya carry Aaedes aegypt and Aaedes albopictus. These are the same type of mosquitoes that can transmit Dengue Fever. These types of mosquitoes are found throughout the world but mostly in countries like India and Africa. The insects become infected with the virus when they feed or bite people that already have the virus and then they spread the virus by biting others. The mosquitoes can be seen biting through the daytime hours and their peak activity is in the early morning and late afternoons.…

    Because diseases are more prevalent during the rainy season, the government kicked off a nationwide anti-dengue campaign last week to educate the population on how to protect themselves. "The most important key to prevent and control diseases is empowering our people with correct information so that they can take steps to stop their transmission and limit the harm that they bring through proper and timely health-seeking behavior," Duque said (Lontayao, Manila Times, 6/10).. Dengue fever, also called dengue, is a potentially serious disease caused by a virus. There are four types of dengue virus that can cause illness in humans (DEN-1, DEN-2, DEN-3 and DEN-4).…

    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 greatly in most tropical countries of the American, African and Asian region. As this has occurred, dengue hemorrhagic fever (DHF) has emerged and produced epidemics in many countries of the region.…
