Transcript: Dengue Fever Madeline Temoin Dengue Fever Dengue Fever Dengue fever is a mosquito borne viral disease present in the tropic and subtropic areas of the world. Dengue has four serotypes ( DENV-1, DENV-2,DENV-3, and DENV-4). The four serotypes came from monkeys then jumped to humans in subtropic and tropic areas. Heilman, JM. (2018, July 5) Dengue fever https://en.wikipedia.org/wiki/Dengue_fever Vectors and Prevalence 1 Vectors and Prevelance Vectors 1 Vectors Dengue virus is transmited primarily through female Aedes aegypti mosquitos. This mosquito can also spread chikungunya, zika fever, mayaro, and yellow fever viruses. WHO (2017, January 3) http://www.who.int/denguecontrol/faq/en/index8.html Vectors 2 Vectors 2 This fever is not contagious. It can only be transmitted from the bite of an infected mosquito. Antiobiotics do not help since Dengue is a virus. After virus incubation the mosquito is able to spread the virus for the rest of its life. DISTRICT OF COLUMBIA DEPARTMENT OF HEALTH ( 2009, April) https://doh.dc.gov/sites/default/files/dc/sites/doh/publication/attachments/Dengue_Fever.pdf Prevelance 1 Prevalance in the world Today there are 2.5 billion people or 40% of the world, who live in areas where there is a risk of Dengue transmission. Dengue is the most common in Southeast Asia and the western Pacific islands. According to the The World Health Organization 50 to 100 million infections occur yearly. There is 500,000 DHF ( Dengue Haemorrhagic Fever) cases and 22,000 deaths yearly, mostly among children.

Some symptoms take up to 2 weeks to develop, but most only take 4 to 6 days. Centers for Disease Control and Prevention,(2014, June 9) Epidemiology. https://www.cdc.gov/dengue/ Symptoms 2 Symtoms 2 Children who have never had the infection usually have more mild cases compared to older children or adults. Some symptoms include; rash, pain behind the eyes, headaches, and flu like symptoms. If symptoms persist it can lead to massive bleeding, shock, and even death. This is called Dengue shock syndrome (DSS). Example of a rash from Dengue.

Cunha, DO, (2017, August 2) https://www.medicinenet.com/dengue_fever/article.htm#where_can_people_get_more_information_on_dengue_fever Immunization 3 Immunization 3 Immunization 1 Dengue vaccine The Dengue virus can be prevented by the Dengue vaccine. The vaccine made by Sanofi Pasteur and is called CYD-TDV, it is sold under the name Dengvaxia. It is said that the vaccince should only be taken if the person has already had the virus because outcomes could be serverly worsened in people who have not previously been infected. This information was a scandal in the Phillippines after 733,000 children were vaccinated. (28 August 2018), dengue vaccine https://en.wikipedia.org/wiki/Dengue_vaccine Immunization 2 The Dengue vaccine is a live attenuated tetravalent chimeric vaccine (a vaccine reducing the harmfulness of a pathogen, by using a new hybrid microorganism). This vaccine was made by using the recombination of DNA technology by replacing the pre-membrane and envelop of the structural genes of yellow fever. About the Vaccine WHO (5 December 2017) http://www.who.int/immunization/research/development/dengue_vaccines/en/ Immunization 3 Treatments There is no specific medicine you can take for Dengue, if you think you might have Dengue fever or have it, you should take pain relievers or acetaminophen. You should avoid taking aspirin, Advil, Aleve, naproxen sodium, and others becuase they could cause severe bleeding, If you have the worse case of Dengue fever it can affect the blood flow in your body, taking blood thinning medications would not be preferable. Some natural methods to treat Dengue fever are to rest, and drink plenty of fluids. It is said that pomegranate, garlic cloves, basil leaves, papaya leaves, and neem leaves are all good remedies because Dengue fever is known to drop platelet count and white blood cell levels. These foods help reverse that progression.
