Oct 2, 2014 · Dengue fever, also known as breakbone fever, is a mosquito-borne infectious tropical disease caused by the dengue virus. This disease occurs primarily in the equatorial regions of Africa, the Americas, South- East Asia, and the Western Pacific. 1 The incidence of dengue fever has increased dramatically since the 1960s, 2 with current estimates of incidence ranging from 50 million2 to 528 ...
Jan 24, 2019 · Dengue is a viral illness that is spread primarily by Aedes mosquitoes and infects ~390 million people each year worldwide 1.It is caused by dengue virus (DENV), which belongs to the family of ...
Feb 24, 2023 · Dengue fever is a dengue virus infection, emerging rapidly and posing public health threat worldwide, primarily in tropical and subtropical countries. Nearly half of the world's population is now at risk of contracting the dengue virus, including new countries with no previous history-like Ethiopia. However, little is known about the epidemiology and impact of the disease in different ...
May 14, 2024 · Dengue viruses are spread to people through the bites of infected Aedes species mosquitoes ( Ae. aegypti or Ae. albopictus ). These are the same types of mosquitoes that spread Zika and chikungunya viruses. These mosquitoes typically lay eggs in containers that hold water, like buckets, bowls, animal dishes, flowerpots, and vases.
Laboratory diagnosis methods for confirming dengue virus infection may involve detection of the virus, viral nucleic acid, antigens or antibodies, or a combination of these techniques. After the onset of illness, the virus can be detected in serum, plasma, circulating blood cells and other tissues for 4–5 days.
Oct 25, 2010 · Each year, the virus infects up to 100 million people and kills about 22,000, most of them children. To infect a cell, the dengue virus initially binds to the cell surface. It gains entry into the cell when it becomes enveloped by the cell membrane during the creation of a pouch-like structure known as an endosome.
Apr 4, 2024 · Mosquito-borne viruses cause more than 400 million annual infections and place over half of the world's population at risk. Despite this importance, the mechanisms by which arboviruses infect the mosquito host and disseminate to tissues required for transmission are not well understood. Here, we provide evidence that mosquito immune cells, known as hemocytes, play an integral role in the ...
