Meteorological factors influence dengue virus ecology by modulating vector mosquito population dynamics, viral replication, and transmission. Dynamic modeling techniques can be used to examine how interactions among meteorological variables, vectors and the dengue virus influence transmission. We developed a dengue fever simulation model by coupling a dynamic simulation model for Aedes aegypti,...

The use of vector surveillance tools for preventing dengue disease requires fine assessment of risk, in order to improve vector control activities. Nevertheless, the thresholds between vector detection and dengue fever occurrence are currently not well established. In Belo Horizonte (Minas Gerais, Brazil), dengue has been endemic for several years. From January 2007 to June 2008, the dengue vec...

Dengue fever is among the most dangerous infectious viral diseases transmitted through bite of infected Aedes Aegypti mosquitoes. One way to decline spread dengue by raising awareness community about mosquito habitats continuous surveillance. The traditional surveillance techniques are difficult, time taking, and can lead severe health risks. This paper presents a possible vector acoustic signa...

The main aim of this study was to find out the barriers in dengue prevention in the Swat District of Khyber Pkhtunkhwa Province, Pakistan. A sample size of 354 respondents were proportionally allocated to each Mahallah or street (Tahir Abad, Angaro Dheri, Usman Abad and Banr) and then randomly selected. The association of the independent variable (barriers to prevention) and dependent variables...

Conditions experienced during larval development of holometabolous insects can affect adult traits, but whether differences in the bacterial communities of larval development sites contribute to variation in the ability of insect vectors to transmit human pathogens is unknown. We addressed this question in the mosquito Aedes aegypti, a major arbovirus vector breeding in both sylvatic and domest...

Dengue dynamics are driven by complex interactions between hosts, vectors and viruses that are influenced by environmental and climatic factors. Several studies examined the role of El Niño Southern Oscillation (ENSO) in dengue incidence. However, the role of Indian Ocean Dipole (IOD), a coupled ocean atmosphere phenomenon in the Indian Ocean, which controls the summer monsoon rainfall in the I...

Mosquito borne diseases such as malaria and dengue cause extensive morbidity and mortality and are a major economic burden within disease-endemic countries. Control of both these diseases, which in most countries are primarily transmitted in and around the home, is difficult. Malaria and dengue are effectively managed through a combination of vector control, drugs and management of clinical ill...

BACKGROUND Dengue viruses (DENV) are considered one of the most important emerging pathogens and dengue disease is a global health threat. The geographic expansion of dengue viruses has led to co-circulation of all four dengue serotypes making it imperative that new DENV control strategies be devised. OBJECTIVES Here we characterize dengue serotype-specific innate immune responses in Aedes ae...

In October 2013, a locally-acquired case of dengue virus (DENV) infection was reported in Western Australia (WA) where local dengue transmission has not occurred for over 70 years. Laboratory testing confirmed recent DENV infection and the case demonstrated a clinically compatible illness. The infection was most likely acquired in the Pilbara region in the northwest of WA. Follow up investigati...

Dear Editor, Dengue is an important arbovirus infection. This infection can result in an acute febrile illness. The important hematological abnormalities included hemoconcentration and thrombocytopenia (1). Due to the decreased platelet count, the patient might develop petechiae and hemorrhagic complication. In endemic area, the presumptive diagnosis of dengue is usually derived by the cl...
