Dengue Fever Risk Higher in Rural Areas Than Cities

In contrast to conventional thinking a recent study found that in dengue-endemic areas such as South-East Asia, rural areas rather than cities may bear the highest burden of dengue fever—a viral infection that causes sudden high fever, severe headache, and muscle and joint pains, and can lead to a life-threatening condition, dengue hemorrhagic fever.

The study led by Wolf-Peter Schmidt from the Nagasaki Institute of Tropical Medicine, Japan, and published in this week's PLoS Medicine, the authors analysed a population in Kanh-Hoa Province in south-central Vietnam (~350,000 people) that was affected by two dengue epidemics between January 2005 and June 2008.

They found that at low human population densities, mostly in rural areas, dengue risk is up to three times higher than in cities, presumably because the number of mosquitoes per individual is higher in low density areas.

The authors show that severe outbreaks of dengue occur almost exclusively in areas falling within a narrow range of human population densities with limited access to tap water, where water storage vessels provide breeding sites for the mosquitoes causing dengue fever. However, as the actual number of people who contract dengue fever in populated areas is high, urban areas still substantially contribute to dengue epidemics.

The authors argue that improving water supply and vector control in areas with a human population density critical for dengue transmission could increase the efficiency of control efforts.

The authors say: "Ideally, all people should have access to reliable tap water, not only to reduce the burden of dengue but also a range of other diseases associated with inadequate water supply such as diarrhea or trachoma, and to realize important economic benefits."

However as supplying everyone with tap water is not a realistic short-term option in many low-income settings, reducing mosquito breeding around human settlements is an uphill struggle.

The authors conclude: "Additional intervention measures in areas with a human population density critical for dengue virus transmission could increase the efficiency of vector control, especially since population density figures are relatively easy to obtain."

There are no specific treatments for dengue fever in modern medicine. Treatment depends on the symptoms, varying from oral rehydration therapy at home with close follow-up, to hospital admission with administration of intravenous fluids and/or blood transfusion. In simple terms the above treatment is : 1] To control fever, medicines which are given [except paracetamol) increase the risk of bleeding. 2) Intravenous fluid / blood transfusion increase risk of fluid overload or reaction. 3) If we give medicine to control fluid overload may lead to weakness. So, this circle is continuous. In contrast to above treatment if we go through Ayurvedic Treatment of dengue the results are much better and fast. The symptoms like fever, muscle and joint pain recover very fast. The 'Neysa' medicine increase platelet count of patient without any side-effect. When platelet count increases it helps reducing risk of any bleeding and hence does'nt require any further blood transfusion thereby again saving from risk of reaction and fluid overload. Also it helps increasing general immunity of patient. Recovers the symptoms very fast. Cover Weakness Increase platelet count Increase blood count Increase haemoglobin Safe and effective Recovery becomes fast. visit www.hivaidscd4.com
