NSF : National Science Foundation issues call for Zika virus proposals .- Fundación Nacional de Ciencia emite convocatoria de propuestas de virus Zika

Hola amigos: A VUELO DE UN QUINDE EL BLOG., El dengue, la fiebre amarilla, encefalitis japonesa, el virus del Nilo Occidental - y ahora Zika. Es nuestra interacción con el medio ambiente de alguna manera responsable del aumento en la incidencia de estas enfermedades?
A través de una carta Estimado colega (DCL), la Fundación Nacional de Ciencia (NSF) de la División de Biología Ambiental Ecología y Evolución del Programa de Enfermedades Infecciosas (EEID) está aceptando propuestas de investigación sobre Zika que se ocupan de la dinámica de transmisión del virus ecológicos.
"Zika es una amenaza seria y único para la salud pública", dice James Olds, NSF director adjunto de Ciencias Biológicas. "También es el último ejemplo de un surgimiento continuo de enfermedades infecciosas para las que necesitamos una mejor comprensión de la ecología y la evolución."

Funding to address ecological transmission dynamics of the virus

Dengue, yellow fever, Japanese encephalitis, West Nile virus -- and now Zika. Is our interaction with the environment somehow responsible for the increase in incidence of these diseases?
Through a Dear Colleague Letter (DCL), the National Science Foundation (NSF) Division of Environmental Biology's Ecology and Evolution of Infectious Diseases (EEID) Program is accepting research proposals on Zika that address the ecological transmission dynamics of the virus.
"Zika is a serious and unique threat to public health," says James Olds, NSF assistant director for Biological Sciences. "It is also the latest example of an ongoing emergence of infectious diseases for which we need a better understanding of their ecology and evolution."
 
Zika outbreak spreading
 
Discovered in Uganda in 1947, Zika has been documented since the 1950s along an equatorial belt from Africa to Asia.
In 2014, the virus spread eastward to French Polynesia, and in 2015 to Mexico, Central America, the Caribbean, and South America, where the outbreak continues.
Zika is transmitted to humans through the bite of an infected Aedes aegypti mosquito. Because these mosquitoes are found throughout the world, it’s likely that outbreaks will spread to new countries, scientists say.
The illness Zika causes is similar to a mild form of dengue fever; it can't yet be prevented by drugs or vaccines.
The most common symptoms of Zika are fever, rash, joint pain, and conjunctivitis ("pink eye"). The illness usually lasts from several days to a week.
However, Zika virus can be spread from a pregnant woman to her unborn baby, and is suspected of causing birth defects. It may also be responsible for neurologic conditions in infected adults, including cases of Guillain-Barre syndrome, muscle weakness as a result of damage to the nervous system.
 
Predictive models and principles of transmission dynamics
 
NSF's EEID Program funds the development and testing of predictive models and discovery of the principles governing the transmission dynamics of infectious diseases such as Zika.
Zika project questions may include, but are not limited to:
  • Which non-human species are hosts of Zika virus? In what frequency and spatial distribution does the virus occur?
  • What is the rate at which Zika virus is transmitted between these vectors/carriers and humans?
  • What is the rate at which Zika virus is spreading on a regional-to-continental scale, and can this spread be modeled and predicted?
  • Can mathematical models of Zika virus transmission dynamics and spatial spread be developed to incorporate the effects of vector control methods?
 
How to submit an NSF EEID Zika proposal
 
NSF proposals may be submitted through one of two routes: as part of the annual call for EEID proposals or as a RAPID proposal (Grant Proposal Guide, Chapter II.D.1).
Before submission of a RAPID proposal, interested researchers should send a one-page summary of the project to zika@nsf.gov. The summary should include a statement of how the results of this research would be used to affect management of, or policies concerning, the spread of Zika virus within the next 12 months.
Projects with a more extended timeline should be submitted to the next EEID deadline.
Proposals that deal with disease etiology, pathophysiology, transmission from mother to fetus, transmission through sexual contact, development of diagnostics, or development of vaccines are not appropriate for submission to the NSF EEID program.
The National Institute of Allergy and Infectious Diseases has also published a notice of interest for research on Zika virus. Proposals on these topics, as well as the others addressed in that notice, should be directed to that agency.

NSF EEID Discovery Article Series:
The National Science Foundation (NSF) is an independent federal agency that supports fundamental research and education across all fields of science and engineering. In fiscal year (FY) 2016, its budget is $7.5 billion. NSF funds reach all 50 states through grants to nearly 2,000 colleges, universities and other institutions. Each year, NSF receives more than 48,000 competitive proposals for funding and makes about 12,000 new funding awards. NSF also awards about $626 million in professional and service contracts yearly.
