University of Hawaii at Manoa assistant researcher Durrell Kapan recently published a paper, Man Bites Mosquito: Understanding the Contribution of Human Movement to Vector-Borne Disease Dynamics, in PLoS One. Published August 26, the paper highlights how daily commuting patterns in mega-cities may be a critically overlooked factor in understanding the resurgence of mosquito-borne diseases such as dengue fever, infecting 50-100 million people annually. "Even a small number of infected people...

Parasitic diseases like Chagas and dengue fever have spread along the border with Mexico and in other poor areas of the United States, researchers say. Scientists say the diseases can cause long-term health problems, including birth defects and heart disease, The Wall Street Journal reports. The diseases thrive in conditions where people have poor sanitation and suffer from malnutrition and are usually associated with poor countries, especially in the tropics.. These are diseases that we know...

The southwest suburbs of Chicago may hold the secret to understanding West Nile virus, a pathogen that has infected thousands since it appeared in North America in 1999."There are few other cities with such good conditions for the virus to persist," explained Tony Goldberg, epidemiologist and professor at the University of Wisconsin-Madison's School of Veterinary Medicine.In a study funded by the National Science Foundation and the National Institutes of Health through their joint program in...

To control mosquito-borne diseases like dengue, researchers need to look at the behavior of people, not just the insect that transmits the disease, according to new research by Steven Stoddard of the University of California, Davis, and intercollegiate colleagues. The study, published July 21 in the open-access journal PLoS Neglected Tropical Diseases, exhibits work by an international, multidisciplinary team of vector biologists, sociologists and virologists studying dengue in Iquitos,...

Experts say more than half of the states in the U.S. now have mosquitoes that are known to spread dengue fever. A new report by the Natural Resources Defense Council showed that two types of mosquitoes capable of transmitting the dengue fever virus are invading Southern and Mid-Atlantic states, creating conditions more favorable for an outbreak. An estimated 173 million Americans live in counties that now contain one or both of the mosquito species, a problem that could escalate with global...

A Red Cross official has sharply criticized the way countries are handling the impact of communicable disease in poor countries, in contrast with flu or heart disease in rich nations. The International Federation of Red Cross and Red Crescent Societies released a reported on Monday that warned the crippling and growing burden of epidemics like dengue fever, polio, or meningitis was not being sufficiently addressed. "We do not see interest, we only see vague, uncoordinated interest in...

U.S. and Costa Rican scientists say they've developed the first climate-based computer model that can predict dengue fever outbreaks in Costa Rica. An interdisciplinary team of researchers from the University of Miami and the University of Costa Rica said the new model can predict dengue fever epidemics with 83 percent accuracy, up to 40 weeks in advance of an outbreak and provide information on the magnitude of future epidemics. The Costa Rican model, the researchers said, can be expanded to...

Scientists use climate variables and vegetation indices to predict and mitigate Dengue epidemics in the American tropics-Dengue Fever (DF) and Dengue Hemorrhagic Fever (DHF) are the most important vector-borne viral diseases in the World. Around 50-100 million cases appear each year putting 2.5 billion people at risk of suffering this debilitating and sometimes fatal disease. Dengue Fever is prevalent in the Tropics. For that reason, an interdisciplinary team of researchers from the...

U.S. medical entomologists have discovered tiny flies known as midges can be used to control invasive Asian tiger mosquitoes that can carry dengue fever. University of Illinois scientists led by Barry Alto said the larvae of midges (Corethrella appendiculata) eat more of the larvae of the invasive mosquito than of the native Eastern treehole mosquito (Aedes triseriatus). That, the scientists said, allows the native mosquitoes to survive even though the invasive mosquitoes are better at...

West Nile virus (WNV) is a virus of the family Flaviviridae. It is part of the Japanese encephalitis antigenic complex of viruses and is found in both tropical and temperate regions. It primarily infects birds but can infect humans, horses, dogs, cats, bats, and other mammals. Humans are generally infected through the bites of mosquitoes and about 90% of West Nile Virus infections are without symptoms. The virion is 45-60 nm and covered with a relatively smooth protein surface. It is...

Dengue fever and dengue hemorrhagic fever (DHF), caused by the dengue virus, is among the spectrum of acute febrile tropical disease and is transmitted by mosquitoes. Occurring mainly in the tropics it can be life threatening and is caused by four closely related virus stereotypes of the genus Flavivirus. It was identified and named in 1779. It has a nickname of "breakbone fever" due to it causing sever generalized bodyache. It tends to be more prevalent in the urban districts of its range...

Flavivirus is a genus of the family Flaviviridae. This genus includes the West Nile Virus, Dengue Virus, Tick-borne Encephalitis virus, yellow fever virus, and quite a few others. Flaviviruses get their name from the yellow fever virus. Flavus means yellow in Latin. Yellow fever was named because if caused yellow jaundice in victims. Mosquitoes and ticks transmit these viruses by biting people. Human infections are usually incidental since humans are unable to replicate the virus. Yellow...

Aedes albopictus (Family Culicidae), the Asian Tiger Mosquito or Forest Day Mosquito, is characterized by its black and white striped legs and small, black and white body. It was native to south-east Asia, and occupied a habitat that spread from Madagascar eastward to New Guinea, and north to the latitude of Korea. The typical member of the Aedes albopictus has a length of about 5 mm. As with other members of the mosquito family, the female is outfitted with an elongated proboscis that she...

  • In music, a work for a keyboard-instrument, like the pianoforte or organ, originally intended to utilize and display varieties of touch: but the term has been extended so as to include many irregular works, similar to the prelude, the fantasia, and the improvisation.
