climate change is occurring as a result of warming of the earth’s atmosphere due to human activity generating excess amounts of greenhouse gases. because of its potential impact on the hydrologic cycle and severe weather events, climate change is expected to have an enormous effect on human health, including on the burden and distribution of many infectious diseases. the infectious diseases tha...

BACKGROUND Climate change affects the survival and transmission of arthropod vectors as well as the development rates of vector-borne pathogens. Increased international travel is also an important factor in the spread of vector-borne diseases (VBDs) such as dengue, West Nile, yellow fever, chikungunya, and malaria. Dengue is the most important vector-borne viral disease. An estimated 2.5 billio...

BACKGROUND Dengue fever/dengue haemorrhagic fever is prevalent in Thailand, where all serotypes are found and the dominant serotype has changed irregularly. Although almost all primary infections present with slight symptoms or are asymptomatic, little is known about the infectiousness of dengue fever. METHODOLOGY A mathematical model of the transmission for dengue virus was constructed cover...

Background and Objective: Dengue fever has become a major public health problem in many world regions due to increased trade, travel, and problems controlling Aedes vectors. This policy brief aims to review, analyze, and present evidence-based policies for dengue prevention and control. Methods: The present research is a compilation of a policy brief in Iran, carried out in 3 stages according ...

Continued geographic expansion of dengue viruses and their mosquito vectors has seen the magnitude and frequency of epidemic dengue/dengue hemorrhagic fever (DF/DHF) increase dramatically. More than 200,000,000 infections and over 2 million cases of DHF occur annually, and dengue is one of the most important emerging tropical diseases in the world. Its dramatically increased incidence and geogr...

Despite Japan's temperate climate, a dengue outbreak occurred in Tokyo for the first time in over 70 years in 2014. We dissected this dengue outbreak based on phylogenetic analysis, travel interconnectivity, and environmental drivers for dengue epidemics. Comparing the available dengue virus 1 (DENV1) E gene sequence from this outbreak with 3,282 unique DENV1 sequences in National Center for Bi...

BACKGROUND The presence of the recently introduced primary dengue virus vector mosquito Aedes aegypti in Nepal, in association with the likely indigenous secondary vector Aedes albopictus, raises public health concerns. Chikungunya fever cases have also been reported in Nepal, and the virus causing this disease is also transmitted by these mosquito species. Here we report the results of a study...

Outbreaks of dengue fever (DF) and dengue haemorrhagic fever (DHF) pose a serious threat to more than 85 tropical and sub-tropical countries throughout the world. The World Health Organization has identified dengue to be one of the most under-reported diseases, with actual cases in the millions. It is also recognised as one of the most important and rapidly rising mosquito-transmitted infection...

j 17 A p il 2 0 17 T by the endemic Aedes aegypti and A. albopictus vectors, together with increasing travel by Australians to dengue-endemic destinations. From 1991 to 2012, most cases of notified dengue in Australia were related to overseas travel, with respective increases in 2010 and 2011 of 298% and 155% above the 5-year mean notification rate; the risk of dengue in travellers returning fr...

Background Most national dengue control programmes rely extensively on insecticides to control the mosquito vectors of this disease. Objectives The objective of this review is to describe current knowledge of the extent of insecticide resistance in dengue vectors and the potential impact of this resistance on control activities. Methods We searched Web of Science and PubMed for studies that inc...
