Oct 5, 2022 · Dengue (DENG-gey) fever is a mosquito-borne illness that occurs in tropical and subtropical areas of the world. Mild dengue fever causes a high fever and flu-like symptoms. The severe form of dengue fever, also called dengue hemorrhagic fever, can cause serious bleeding, a sudden drop in blood pressure (shock) and death.
Sep 21, 2023 · At lower average temperatures (<18°C), a temperature fluctuation of 6.26°C between day and night increased the ability of Ae.aegypti to infect and transmit DENV-1. However, at higher average temperatures (≥18°C), the same temperature fluctuation between day and night reduced the vector competence of Ae.
Mar 3, 2013 · For dengue viruses, several studies have identified the role of temperature in infection and transmission by Ae. albopictus and Ae. aegypti mosquitoes and its role on the incidence of dengue in nature. 34 – 37 Despite the long history of relating temperature to vector biology, relatively few studies have evaluated the net effect of ...

May 12, 2023 · Dengue, or dengue fever, is a disease caused by infection with the dengue virus (DENV), a member of the Flavivirus genus (Flaviviridae) that also includes yellow fever and Japanese encephalitis. Milder cases can range from asymptomatic to clinical manifestations that include high fever, severe headaches, retro-orbital pain, joint and muscle pains, vomiting and rash. DENV is classified into ...

Jun 6, 2022 · Dengue fever is caused by one of four dengue viruses. When a mosquito infected with the dengue virus bites you, the virus can enter your blood and make copies of itself. The virus itself and your immune system’s response can make you feel sick. The virus can destroy parts of your blood that form clots and give structure to your blood vessels.
Here, we show that diurnal temperature range (DTR) affects two important parameters underlying dengue virus (DENV) transmission by Aedes aegypti. In two independent experiments using different DENV serotypes, mosquitoes were less susceptible to virus infection and died faster under larger DTR around the same mean temperature.
