Question

Summary Information Below In Your Own Words Dengue fever (DF) is occurring worldwide, and it has emerged as a global health threat due to high mortality and morbidity, specifically in tropical and subtropical regions. The World Health Organization has deep concerned to this disease being a large section of population affected. Around 2.5 billion peoples are at risk of dengue virus (DENV). Over 100 countries including Europe and the United states are affected due to DENV. DF is the most widespread viral disease. There are four different serotypes (DENV-1 to DENV-4) of DENV but now discovered DENV-5 serotype also. DENV is transmitted from person to person by the bite of infected female Aedes aegvpti and Aedes albopictus mosquito. Unfortunately, there are no effective approved anti-dengue agents and vaccine to treat viral infection Researchers have paid attention toward medicinal plants in search of natural compounds which can be used as anti-dengue. Therefore, our focus is on the extract of medicinal plants which may be more effective, safer, and less toxic than synthetic drugs. In the present review paper, the brief description of 35 medicinal plants which possess anti-dengue activity has been documented along with their active components. This study will be helpful to establish that natural products may have good potential source of new anti-dengue compounds.

Answer 1

Dengue fever is global health threat because of high mortality and morbidity.WHO is concerned about this because about 2.5 billion people are at risk of DENV over 100 countries including Europe and US. This is most widespread viral disease and it's vector is Aedes aegypti and Aedes albopictus mosquito. Four serotypes were know (DENV1-DENV4) but now DENV 5 has emerged.No definitive treatment is available.Research is going on medicinal plants to find anti-dengue compounds which will be more effective,safer and less toxic than synthetic drugs.Till now about 35 plants have been documented having anti-dengue property along with their active components. This research will help to combat dengue.
