Answer: Dengue fever has continued to haunt mankind for the last several centuries with historical accounts of this disease from Africa which are between five to six hundred years old. The first outbreaks of dengue fever reached Asia, South America and Africa concurrently in the 1780s. Now this disease is endemic in several regions including Southeast Asia, Latin America, Asia, and the Caribbean; areas with a high vector population of the mosquitoes that causes the disease, the Aedes aegypti and Aedes albopictus. Dengue fever has become a prominent infectious disease with outbreaks in as many as 120 countries of the world. The annual disease burden of this disease has reached 40 million with dengue becoming the second-most prevalent mosquito-borne infection after malaria in recent decades. The illness causes significant morbidity with the cases of dengue haemorrhagic fever (which is a complicated form of this disease) touching several thousand a year. This disease was eliminated from Pakistan in the 1970s only to reappear in 1994. The recent epidemic of dengue fever in the country has been one of the biggest in the history of this country. Attention has been refocused on this condition due to the scale of devastation it has caused, in terms of health care related and economic costs. Several countries including Sri Lanka have taken measures including case surveillance, research and interventions designed to eradicate the vector for this disease. Unfortunately, Pakistan has lagged behind in this respect. Health and economic research specific to dengue is urgently needed to ensure informed decision-making on the various options for controlling and preventing this disease. Several organisations, including various academic institutions and non-governmental organisations have initiated projects designed to address the menace of dengue fever. One such effort is the research being conducted by the Fatima Memorial System and Hospital in Lahore in collaboration with the University of Punjab. While significant effort is on at the global level to institutionalise health research within the health care systems of countries, the developing countries are not benefitting from these endeavours owing to their severe health research capacity constraints. Pakistan too has to date not benefitted from the global initiatives to strengthen health research in developing countries. More than ever before our country needs to develop informed policies and implement evidence-based interventions to protect and promote the health of its people, curtail wasteful expenditure and thus accelerate its economic development. The options for controlling this disease at this time include vector control and optimal medical therapy for the effected patients. Both these interventions are limited in several ways in their ability to eliminate this disease. A dengue vaccine would fill a substantial need as almost 3.6 billion people are at risk from this potentially fatal infection. Vaccines are in the process of development at this time and preliminary trials have given us hope of being able to control this disease. Development of vaccines has, however, been complicated by the need to immunise against all four serotypes of this virus simultaneously. There are currently at least six vaccines in various phases of clinical trials. It is anticipated that a safe and effective vaccines will be licensed for dengue fever in the next five years.
Answer: Denegue is transmitted from person to person via the female Aedes mosquitoes. Mosquitoes acquire the virus while feeding on the blood of an infected person. Once infective a mosquito is capable of transmitting the virus to for the rest of its life, during probing and blood feeding. Infected female mosquitoes may also transmit the virus to the next generation of mosquitoes.
Answer: its something called plasma leakage. patient with just dengue didnt suffer plasma leakage, but the other with dengue hemorrhagic fever does. you can know whether someone get a plasma leakage from: 1. anamnese: difficult to breath (due to a pleural effusion), distended abdomen (due to an ascites) 2. phys. diagnostic: derivation of breathing sound, undulation test, edema, poor perfusion and shock sign 3. lab findings: hemoconsentration (higher Hb and PVC)
Answer: The cause of dengue is being bitten by a mosquito which has taken a blood meal from an infected carrier, usually human. Much the same as Malaria, which is only transmitted from human to human by the mosquito. West Nile Virus, EEE and other "flu like symptom" illnesses can be transmitter by mosquito from a human, bird, horse etc. The problem with Dengue is if you get it the second time it can be deadly.

Click on Florida to see how bad it really is. What we need is a non-toxic pesticide that also keeps repelling mosquitoes for more than a few hours.
Answer: you get dengue if you bited by some mosquitoes named Aedes aegypty (the female ones) that has been biten someone who has a bunch of dengue viruses inside their blood. its like a MLM virus franchise
Answer: If we are talking about the disease itself, it is a viral disease,this means not direct medications, it is self limiting and you justhave to strengthen the body systems to fight off the infection andalso though sufficient fluid management and monitoring of theplatelet counts. However, if you are talking about the mosquitoethat brings it, then you need to clean regularly, make sure watercontainers are covered and cleaned regularly, make use of isectrepelants and do not have stagnant waters lying around the home orplace.
Answer: There are four types of dengue fever Dengue fever can be caused by any one of four types of dengue virus: DEN-1, DEN-2, DEN-3, and DEN-4. A person can be infected by at least two, if not all four types at different times during a life span, but only once by the same type. (Source: excerpt from Dengue Fever: NIAID)
