Introduction
Dengue fever is considered as the fastest emerging viral infection which is spread by the female mosquito “Aedes aegypti.” ( Fever,2011). The disease has caused major health effects in many tropical and sub-tropical countries in Asia, Western Pacific and Central and South America ( Fever,2011).The disease causes flu-like illness which develops into serious complication which is called dengue haemorrhagic ( DHF). The disease has grown drastically over the decades, and it has affected approximately 2.7 billion people globally. Most of the population affected about 75% is that from Asia and Pacific region. With the changing disease epidemiology, the outbreaks of the disease are increasing as the disease is spreading to new areas. The disease mostly affects children under five years of age. Approximately 50-60 million cases of dengue fever occur annually worldwide, and half of the infected population require medical attention every year ( Fever,2011). The disease also causes deaths to about 3 % of the population affected by dengue fever. Dengue fever has no specific treatment, but early detection and proper medical attention will save patients’ lives. The disease is a major epidemic in Africa in the World Health Organizations regions. Prevention and control of this disease will depend on how the vectors will be monitored effectively. Vaccine for the dengue fever has been authorized to areas experiencing this kind of illness. The vaccine is administered to persons aged 7- 45 years of age ( Fever,2011).
Cause Of The Dengue Fever
The dengue fever virus is of the family Flaviviridae and genus Flavivirus. Aedes mosquito transmits the virus. The mosquito mainly lives in altitudes of 1000 m below sea level. The mosquitos mostly bite during the morning hours, but they can also bite at other...

Dengue Fever

...Dengue (pronounced DENgee) fever is a painful, debilitating mosquito-borne disease caused by any one of four closely related dengue viruses. These viruses are related to the viruses that cause West Nile infection andyellow fever.An estimated 390 dengue infections occur worldwide each year, with about 96 million resulting in illness. Most cases occur in tropical areas of the world, with the greatest risk occurring in:*.The Indian subcontinent*.Southeast Asia*.Southern China*.Taiwan*.The Pacific Islands*.The Caribbean (except Cuba and the Cayman Islands)*.Mexico*.Africa*.Central and South America (except Chile, Paraguay, and Argentina)Most cases in the United States occur in people who contracted the infection while traveling abroad. But the risk is increasing for people living along the Texas-Mexico border and in other parts of the southern United States. In 2009, an outbreak of dengue fever was identified in Key West, Fla.Dengue fever is transmitted by the bite of an Aedes mosquito infected with a dengue virus. The mosquito becomes infected when it bites a person with dengue virus in theirblood.

Dengue Fever Case Study

...1.1. Background Information Aedes mosquitoes are the vectors that cause the mosquito-borne disease such as Dengue fever (DF) and dengue haemorrhagic fever (DHF). The cases of dengue are keeping increasing from time to time and this has made it become a serious international concern. Initially, in the 1950’s only 5 countries documented dengue but up until now the dengue cases were reported in more than 100 countries (Guha –Sapi & Schimmer, 2005). Dengue can be transferred when the mosquitoes infected with one of the four dengue virus serotypes known as DEN-1, DEN-2, DEN-3, and DEN-4 (WHO, 2014). There is no vaccine or any exact medication to treat dengue. In Malaysia, dengue fever cases are not something bizarre. Selangor is one of the states that had reported with high...

Tawa Tawa as Cure for Dengue Fever

...Chapter I: The Introduction A. Introduction Dengue is a mosquito-borne infection that has become a major international public health concern. Dengue is found in tropical and sub-tropical regions around the world, predominantly in urban and semi-urban areas. Dengue Hemorrhagic Fever (DHF), a potentially lethal complication, was first recognized in the 1950’s during dengue epidemics in the Philippines and Thailand. DHF affects most Asian countries and has become a leading cause of hospitalization and death among children. There are four distinct, but closely related, viruses that cause dengue. Recovery from infection by one provides lifelong immunity against that virus but confers only partial and transient protection against subsequent infection by the other three viruses. Sequential infection increases the risk of developing DHF.1 1 “Dengue and Dengue Hemorrhagic Fever,” World Health Organization, March 2009, 15 Oct. 2011 <http://www.who.int/mediacentre/factsheets/fs117/en>. 2 There is no specific medicine or antibiotic to treat DHF. For typical dengue, the immediate concern is the relief of symptoms. Adequate fluid intake for proper body hydration and rest is important. All else will depend on the person’s immune system. However, since the Philippines is abundant with herbal medicines, the Tawa Tawa is being touted as an alternative cure to DHF. The Tawa Tawa is described as having numerous flowers which measures about 5 to 8 centimeters each......

Dengue Fever Remedy

...DENGUE FEVER REMEDY Pawpaw (Papaya) Leaf Juice Is A Natural Cure For Dengue Fever Remedy: Two (2) pieces of raw Pawpaw (Papaya) leaves. Clean the leaves and pound and squeeze with a filter cloth. You will only get one tablespoon of juice per leaf. So, take two (2) tablespoons of Pawpaw (Papaya) leaf juice once a day. Do not boil, or cook, or rinse the leaves with hot water, as it will lose its strength. Use only the leafy part of the Pawpaw (Papaya) plant, and not the stem or sap. The juice is very bitter, and you have to swallow it. But it works. Simple and Effective – blend the leaves, squeeze the juice, drink immediately. Case Studies: 1. Male student was in a critical condition in the intensive care unit, when his blood platelet count dropped to 15, after a blood transfusion of 15-litres. The boy’s father was so worried that he sought a friend’s recommendation, and his son was saved. He gave his son the raw juice of the Pawpaw (Papaya) leaves. From a platelet count of 45 (after a blood transfusion of 20-litres), and after drinking the raw Pawpaw (Papaya) leaf juice, his platelet count jumped instantly to 135.

Prophylactic Platelet Transfusion in Dengue

...Review Article 539 Dengue Prophylactic Platelet Transfusion—Changa Kurukularatne et al When Less is More: Can We Abandon Prophylactic Platelet Transfusion in Dengue Fever? Changa Kurukularatne,1,2MD, Frederico Dimatatac,1,2MD, Diana LT Teo,3MBBS, MSc, FRCPath, David C Lye,1,2,4 MBBS, FRACP, FAMS, Yee Sin Leo,1,2,5 M.Med (Int Med), FRCP, FAMS Abstract Dengue fever (DF) has several hematological manifestations including thrombocytopenia and increased bleeding risk. Prophylactic platelet transfusion—in the absence of major bleeding—is utilized in DF with thrombocytopenia with the intention of preventing hemorrhagic complications. However, prophylactic platelet transfusion in DF is neither standardized nor supported by clinical evidence. We conclude that risks, costs and poor resource utilization associated with prophylactic platelet transfusion in DF far outweigh any potential hematological benefit, and as such, should not constitute routine clinical practice. Ann Acad Med Singapore 2011;40:539-45 Key words: Thrombocytopenia, Preventitive, Arbovirus, Bleeding, Hemorrhage Introduction Dengue fever (DF) is the most common mosquito-borne human viral illness worldwide, and has rapidly spread to reach hyper-endemic proportions in the urban tropics over the last quarter of a century.1 With an estimated 2.5 billion people at risk and a global annual incidence of 50 million cases, DF has been identified as an example of a potential international public health......

The virus in the movie was much more deadly and acute than the Zika virus, it was spread through human contact, and it caused worldwide panic. The Zika virus is being linked to other serious health concerns and in most cases only presents with mild symptoms. In both instances the WHO and CDC are scrambling for a vaccine. Both can be considered pandemics because they are infectious and affecting multiple continents. Primary prevention refers to the measures taken to prevent the disease or injury (Stanhope & Lancaster, 2014). Primary prevention in the case of Zika would be getting rid of stagnant water, using insect repellent, restricting......

...Science High School Faculty Submitted by Trevorha Kyle M. Basillote Leah Jeanette M. Lozano Lyrah Mae D. Enoc Jhanna C. Flores Nicole L. Constantino Mahonri A. Alquisalas January 26, 2016 Victorias City Background of the study The population of our country are mostly composed of students. And one of the responsibility of a student is to clean their school or classroom to be specific. They tend to use (commercial) floor wax to have a clean and shiny floor. So we decided to make a floor wax which is very affordable and can give an equal quality as the commercial can, using mainly banana peel, gasoline and candles. Some people get allergic reactions to the chemical contents of commercialize floor wax. At the same time the dengue cases in our country are still relevant. Aside from making a natural and affordable floor wax, we added a content of mosquito repellent which is the mint leaves extract. The banana is an edible fruit, botanically a berry, produced by several kinds of large herbaceous flowering plants in the genus Musa. We use banana peels as one of the main components of our floor wax because it gives "slippery effect" for greater friction. On the other hand, we use Mint Leaves Extract for Mosquito Repellent. Mint Leaves are any of a family (Labietae, the mint family) of aromatic plants with a square stem and a 4-lobed ovary which produces four one-seeded nutlets in fruit. The market is full of products like tooth paste, chewing gum, breath......

Intro

...Introduction Dengue fever has become a common problem in the typical community. Its main cause being the clogged drains, unsanitary canals, and polluted surroundings. In these environments, the insect spreading dengue, Aedes aegypti, thrives. The researchers decided to focus on the root cause of the disease. The researchers would like to find an alternative, more economical method of exterminating them in their breeding places other than commercial insecticides. And in this pursuit to find a substitute, the researchers came across the guava fruit (psidium guajava), which had promising properties. (insert stuff about why we chose guava blahblah about properties….. use RRL for info.) The guava fruit was collected, osterized, soaked in ethyl alcohol, concentrated and evaporated to obtain a semi-solid extract. There were six blocks for replicates, five groups with 100mL water and different guava extract concentrations each – 3%, 5%, 8%, 12.5%, and 15% - and commercialized larvicide as positive control and one setup with dechlorinated water with 1mL ethanol. The commercial larvicide proved to be the most effective, but the guava extracts also have a positive effect on the larvae, though minimal. The study should be able to aid in the reduction of health problems brought about by Aedes aegypti. It may also help the community in controlling the mosquito population at an early stage by means of an eco-friendly larvicide. Not only will it be eco-friendly, it will......

Platelet Increasing Activity of Euphorbia Hirta

...such as chronic liver disease and dengue hemorrhagic fever. In most rural areas a health care institution is often inaccessible and most patients cannot afford high cost medication. Henceforth, herbal medicines are often used as an alternative treatment. Inadequacy of providing supportive treatment to correct the decrease of platelet is fatal to patients. Thus, several decoctions of herbal plants are purportedly used to improve platelet count. Recently, the mortality rate in heparin – induced thrombocytopenia (HIT) has been reported as high as 20% (Greinacher & Lubanow, 2003). Retrospective data shows that up to 8% of heparinized patients will develop the antibody associated with HIT and that approximately 1–5% of patients on heparin will progress to develop HIT with thrombocytopenia suffering from venous and/or arterial thrombosis in at least one-third of cases (Warkentin et al., 1998). Heparin – induced thrombocytopenia (HIT) is a potentially devastating immune mediated adverse drug reaction caused by the emergence of antibodies that activate platelets in the presence of heparin. Despite thrombocytopenia, bleeding is rare; rather, HIT is strongly associated with thromboembolic complications such as death and amputation which involves in both arterial and venous systems (Franchini, 2005). One of the popular diseases in the tropical country that is responsible for the drastic decrease in platelet count (thrombocytopenia) could be Dengue as reported by the Department of......

... The essential oils that can be extracted from lemon and orange peel are the one that makes the mosquitoes fly away. Lemon and orange is basically known as a fruit that we can eat. We can also make other product with its citric acid and their peel in whitening skin and an insect repellant. An insect repellent is a substance applied to skin, clothing, or other surfaces which discourages insects (and arthropods in general) from landing or climbing on that surface. Effective insect repellents can protect you from serious mosquito- and tick-borne diseases. In the United States, mosquitoes can transmit diseases like St. Louis encephalitis and West Nile virus. Ticks can transmit serious diseases like Lyme disease, Rocky Mountain spotted fever, and Ehrlichiosis. I. Background of the study Today, lemon and orange are made not only for the fruit that it produces. The peel also can be useful and healthy for our body. It can also give some vitamins that our body need. It can also be useful in body whitening. Insect repellent is very common for making mosquitoes fly away.

Increase Platelet with Tawatawa

...Possibility of Papaya (Carica papaya) Leaf Extract to Increase Platelet Count Background of the Study Nowadays, many people especially children under the age of 15 are suffering from dengue hemorrhagic fever with about 2.5 billion (2/5 of the world population) are at risk and 50 million are infected worldwide annually, and a mortality rate ranging from 1 percent to 2.5 percent, for those who receive treatment. For those without treatment, the death rate could be 20 percent or higher. This viral illness is cause by a bite from a female Aedes Aegypti which lives in places that store water such as in the tires, bottles and cans. Dengue lowers the number of platelets in the blood and it may lead to bleeding or death since it cannot supply clotting due to thrombocytopenia (lower than normal number of platelets in the blood). In the Philippines, dengue is now one of the leading causes of the increase of mortality rate. It is the seventh leading cause of death in the country with more than 60,000 cases hospitalized and nearly 500 others died as of the year 2010 and it is said that it was the highest percentage ever recorded in the history of this problem in the country. It is thought to increase until the present time especially that today, weather is changing and El Niño phenomenon is occurring very often. Hence, the researchers came up of an idea on how to increase the number of......
