Dengue Fever
Dengue Fever is a disease with no cure. It is spread using mosquitoes as a vector. Scientists think they may have a way to stop the spread of this disease which is one of the "world's most pressing public health issues." Read the following article from sciencedaily: Flightless Mosquitoes Developed to Help Control Dengue Fever. Describe dengue fever, how it is transmitted, and how scientists will be able to stop the spread of this disease.

So the Dengue Fever is transmitted by vectors.Which are the mosquito's.You can be infected with one bite from a female.There have been no vaccines or anything that can prevent you from getting the fever.In other words it is non-curable.The scientists have thought about breeding the infected females with not-infected males.So then the females will not be able to fly and therefore they cannot pass on the dengue fever.I think that this experiment could work but you just have to get a bunch of those non-infected males out there in the world for the males to mate with the females and then they can't fly anymore.
ReplyDeleteThe fever is obviously spread by mosquitoes. These are the vectors. The problem is that one female's bite can infect you and there is no vaccine/cure. Scientists want to selectively breed the insects to stop the spread of the illness. Because this has worked in the past I think it can work again.

Dengue Fever is transmitted through mosquitoes and it has no cure or any type of vaccination which allows it. It is transmitted by only the female mosquito, and for some reason not the male mosquito. Scientists are working on ways to stop the spread of Dengue Fever by genetically modifying mosquitoes so that the female mosquito does not fly. This means that there is no ware of spreading the disease because the males do not carry it. The male mosquitoes will mate with the genetically modified females and create a whole new generation of mosquitoes that cannot carry the Fever. This is how it will be completely stopped from spreading.
ReplyDeleteDengue Fever is a disease spread by mosquitoes and does not have a cure to it by any sort of vaccine or drug. The disease is spreading in northern Argentina, northern Australia, Bangladesh, Barbados, Bolivia, Brazil, Cambodia, Costa Rica, Dominican Republic, Guatemala, Guyana, Honduras, India, Indonesia, Jamaica, Laos, Malaysia, Mexico, Micronesia, Pakistan, Paraguay, the Philippines, Puerto Rico, Samoa, Singapore, Sri Lanka, Suriname, Taiwan, Thailand, Trinidad, Venezuela, Vietnam, and increasingly in southern China. There is no known vaccine, but scientists are in research of developing one for this disease. Scientists have researched that genetically modifying the mosquitoes can keep female mosquitoes from flying. A new generation of mosquitoes will be created that cannot carry the disease. This could be the only way of stopping them until a vaccine for treatment is developed.
ReplyDeleteDengue fever is a disease that causes sever flu like symptoms in humans and is spread by female mosquitoes. Dengue fever is transmitted through an infected female mosquito bite and there is no current vaccine or treatment for it. Scientists have just developed flightless female mosquitoes by genetically altering male mosquitoes which will mate with wild females and the next generation females will be flightless. This will signifcantly reduce or even eliminate the Dengue Fever. After the flightless females die the Dengue Fever will not spread. This is a great alterative to dangerous pesticides. Let's hope that this can also be applied to other mosquito species that transmit malaria and West Nile fever.
ReplyDeleteThere is a type of fever known as Dengue fever. This fever is caused when a female Aedes aegypti mosquito bites a human. This fever causes severe flu like symptoms, so it can be mistaken as a just a flu. There is a one difference though: There is no cure for Dengue Fever. So scientists have to find another way to stop people from being infected. Since there is no cure, or treatment scientist have to eliminate the problem by getting rid of the source. They will genetically modify male mosquitoes that will stop the fever when the male mates with the female. This will stop the fever from spreading and it will eventually go away. Disposing of this disease is also smiled upon because it does not harm the environment.
ReplyDeleteDengue fever is an illness that has flu-like symptoms. It is carried by female Aedes aegypti mosquitos, therefore, the mosquitos act as vectors. The main problem with the Dengue fever is that there is no vaccine or cure, so what scientists have been doing is breeding the female mosquitos to not be able to fly, which should end up with less cases of the Dengue fever.
ReplyDeleteThis article was about Dengue fever. There is flu-like symtoms for dengue fever. This virus is carried by female mosquitos but not male mosquitos. Scientists have developed flightless female mosquitos which will prevent them from spreading the fever. This will make it hard for the females to survive long in the wild. It will be interesting to see if the whole species die off or if the females can adapt to live flightless. Also it will be hard to make all the female mosquitos flightless because the flightless ones will die off and may not be able to pass on their genes so this plan may not work.
ReplyDeleteI think it is interesting that only the male mosquitoes can fly. Then, when they mate with a female, they pass on the genes and the next female generation cannot fly. This can be a good thing because the mosquito that injects the dengue virus cannot fly, meaning the chance of getting bit will be lower. Although this does not prevent the virus, it only decreases the chance. Many scientists are working on a way to control this virus, so that people can be less afraid and less cautious in the environment.

ReplyDeleteDengue fever is a virus that is spread through the bite of an infected female Aedes aegypti mosquito as a vector. It causes severe flu-like symptoms and - as there is no vaccine or treatment – is among the world's biggest public health issues. Now, using concepts developed by Oxitec's Luke Alphey, researchers have made a genetic alteration in the mosquitoes that interferes with wing muscle growth in female offspring. The result makes them incapable of flying. Introduction of a new strain of mosquitoes such as these may help slow the transmission of dengue fever, according to UC Irvine and British scientists. UCI researchers together with colleagues from Oxitec Ltd. and the University of Oxford created the new breed. When genetically altered male mosquitoes mate with wild females and pass on their genes, females of the next generation will be unable to fly. The approach offers a safe, efficient alternative to harmful insecticides. Not limited to the dengue fever vector, researchers noted that this approach could be adapted to other mosquito species that spread diseases like malaria and West Nile fever.
The dengue fever has no cure and it affects about 50 to 100 million people every year. The vector for the dengue fever is the female Aedes aegypti mosquito. Since the dengue fever consumes a lot of the population, scientist had no option rather than the find a way to reduce or to eliminate the fever. Now scientist have came up with a way to alter the Aedes aegypti so it will become flightless. This helps since the mosquito is flightless, it would not be able spread the disease to other humans. Scientist estimate that it will take six to nine months before every female Aedes aegypti is flightless
