DENGUE HEMORRHAGIC FEVER (DHF)
• Tropical areas
• Aedes aegypti
• Great affect on society and military activities
DHF
Heat
Heat clearance
Blood
• Blood nourishment
Body fluid
• Body fluid reproduction

OBJECTIVES
OBJECTIVES
• Observe the impact of climate change on DHF pattern
• Evaluate the effectiveness of “Sinh tan chi huyet“ remedy in treatment DHF in combination with the background regimen recommended by the Ministry of Health
METHODS
1- Clinical trial to evaluate the therapeutic effect of the “Sinh tan chi huyet“ remedy on DHF at MITM
METHODS
2- Survey and statistic data of the climate pattern in 3 ending months of 2015 comparing to the mean climate pattern yearly at the same time in Hanoi, Vietnam
SELECTION CRITERIA IN CLINICAL STUDY
Dengue hemorrhagic fever (DHF) • sudden high fever continously from 2-7 days; bleeding under
the skin • headaches - pain fovea; muscle pain • heamatocrit normal or elevated; platelet count normal or
• Clearing heat • Nourishing Qi and blood • Reproducing body fluid • To treat DHF was suitable to TVM theory
The remedy of “Sinh tan chi huyet” have many effects
• Shortened the duration of treatment • Increased the ratio of recovery patients • Reduced the number of patients with severe conditions

CONCLUSION
CONCLUSION
There was expression of the climate change impact on the number of patients hospitalized with DHF
“Sinh tan chi huyet” remedy combined with the background regimen has
effect on DHF treatment
RECOMMENDATION
Global solution is needed to cope with the impact of climate change on
