Dengue is a serious vector borne viral disease in the tropical and subtropical region. Infection is caused by dengue viruses. Dengue has increased very fast in the last five decades. 50 to 100 million new dengue infections are reported globally every year. The lifespan of Aedes mosquitoes change depending on temperature and rainfall. The averages of lifespan of an Aedes albopictus can 19.1 days and 19.94 days for Aedes aegypti respectively. The dengue mosquitoes show anthrophilic endophilic and exophilic resting behavior and produce it a very effective vector of dengue, Chikungunya and Zika viruses. There are no specific antiviral medicines and defensive vaccine for dengue fever. However researchers are still working on finding a specific medicine or vaccine. The best way is prevention cure.
