Who, What Is The Natural Host of The Dengue Fever Virus?

A new born aedes mosquitoe has no dengue fever virus in its body.
How did the virus get inside before the mosquiteo bite a person and pass the virus on.
Human are not natural host since we all get sick with the dengue fever virus inside us.

Thanks for the wonderful answer thus for. It does provide more light to the question.
So it seems, the Aede PICK UP the dengue virus from its surroundings, then went on to bite a human and the human become sick. The virus spread when the mosquito or other mosquitoes bite the infected person and then bite more people.

Description

The virus that causes dengue fever is called an arbovirus, which stands for arthropod-borne virus. Mosquitoes are a type of arthropod. In a number of regions, mosquitoes carry this virus and are responsible for passing it along to humans. These regions include the Middle East, the far East, Africa, and the Caribbean Islands. In these locations, the dengue fever arbovirus is endemic, meaning that the virus naturally and consistently lives in that location. The disease only shows up in the United States sporadically.

In order to understand how dengue fever is transmitted, several terms need to be defined. The word "host" means an animal (including a human) that can be infected with a particular disease. The word "vector" means an organism that can carry a particular disease-causing agent (like a virus or bacteria) without actually developing the disease. The vector can then pass the virus or bacteria on to a new host.

Many of the common illnesses in the United States (including the common cold, many viral causes of diarrhea, and influenza or "flu") are spread because the viruses that cause these illness can be passed directly from person to person. However, dengue fever cannot be passed directly from one infected person to another. Instead, the virus responsible for dengue fever requires an intermediate vector, a mosquito, that carries the virus from one host to another. The mosquito that carries the arbovirus responsible for dengue fever is the same type of mosquito that can transmit other diseases, including yellow fever. This mosquito is called Aedes egypti. The most common victims are children younger than 10 years of age.

So no a newborn mosquitoe does not have the virus but it can be transmitted by other mosquitoes to it. the article I included goes over the diesease in full detail.

You still sound confused as to what the term "natural host" means. As I pointed out, there are several animals including man that can serve as a natural host. And you still seem not to recognize that an Aedes CAN be born with dengue through vertical transmission. Read teh references. Report It

yes...it likes to feed on blood, theres where it gets infectedd.
then it passes it on


hope it helpsl

Dengue is caused by Group B arborivus

Yes, this is a nice question. You are right in telling us that naturally, there is no Arbovirus-Dengue Virus present in the Aedes mosquito bod..they get it from the person already infected by Dengue. You see,viruses tend to develop overtime. But they need a host that will help them live and develop.For some reasons, viruses that originally not present in the body of a mosquito develops ( just like what happened to Ebola Virus and AIDS from monkeys). But for the virus to reach the stage that it is ready for transmission..they need another host for that..unfortunately..it is human. So when they are fully develop again and the aedes mosquito bites..it will repeat its cycle until it is ready to be introduced to the human body )..then the Pathogenesis goes on. So to prevent it from spreading the Aedes has to be eradicated. Hope this helps.

Humans are the primary natural hosts of dengue. Non-human primates in Africa and Asia can also serve as a reservoir. The Aedes has grown up in close association with humans, and the Aedes gets the virus from infected humans.

You confuse the situation of accidental hosts (as for cysticercus) with the situation of natural infection. For dengue, the native host is humans.

IT IS ALSO INCORRECT TO SAY THAT AEDES CANNOT BE BORN WITH DENGUE: vertical transmission in mosquitoes, from mother to offspring is wel described. In case you dont believe it, read teh reference.
