Aedes Aegypti The mosquito that has attracted the most attention is the mosquito Aedes aegypti. It belongs to the family Culcidae, consisting of about 2,500 species (Encyclopedia Britanica 1999), along with other genera of mosquitoes such as Anopheles, Culex, Orthopodomyia, and the Toxorynchites, to name a few (Womack 1993, E.B. 1999). This mosquito has been known best for transmitting yellow fever and human dengue throughout the tropic and subtropic of the Americas (Womack, M 1993). This mosquito
cannot be used to combat Zika virus. The speaker received other questions on issues that require further investigation and methods of prophylaxis. The speaker cautioned against traveling to South America and Central America during seasons when Aedes Aegypti is very active. All in all, this seminar was very informative about the various unknown effects of Zika virus and revealed the need for further research into the detrimental effects of Zika virus on pregnant women and their
dull until you prove the doctor right; another person fell victim to the infectious Yellow Fever virus. There is no definitive history or discovery date, but it is assumed that Yellow Fever originated in Africa and was brought to the Americas by Aedes aegypti mosquitoes “hitchhiking” on trade and slave ships. The first believed outbreak happened in 1648 in the Yucatán. It is “believed” because early documentation of disease and illness was not thoroughly investigated or described, they could have been
the family Togaviridae and genus Alphavirus that have been associated with large sporadic epidemics (Schwartz & Albert, 2010) (Suhrbier, Jaffar-Bandjee, & Gasque, 2012). CHIKV is transmitted to humans by infected mosquitos of the genus Aedes, Aedes aegypti and Aedes albopticus (Torres, et al., 2015). This virus was first identified in 1952 in East Africa and later caused large outbreaks in tropical Asia and Africa (Sissoko, et al., 2009). Chikungunya fever is a re-emerging disease; appearing again
has a widespread incidence. There are four closely related virus strains that cause dengue that are known as DENV 1, DENV 2, DENV 3, and DENV 4. The virus is transmitted to humans indirectly by mosquitos, of which Aedes aegypti and Aedes albopictus are the primary vectors. The Aedes aegypti mosquito is also recognized as the species that spreads other viral diseases such as chikungunya, yellow fever, and the Zika virus. Dengue has a pronounced presence in tropical regions and because urbanization and
Introduction What is dengue fever? Dengue fever is caused from a transfer of misquotes bite to human that contains the Aedes aegypti virus. The disease affects people that live in countries such as South Asia Pacific, Caribbean and South America. There has been a major outbreak in India due to large demand to live urban area. One major problem these countries have is their drainage system when rain falls. When it rains, it leave a large body of water that become unclean which is a target site
person, it is then affected and every time it bites someone the virus spreads. The type of mosquito that carries this virus is called Aedes Aegypti, and looks the similar to other mosquitoes. There is another type of mosquito that also causes this illness, the aedes albopictus. This type of mosquito is different to aedes aegypti because it has wolbachia. The aedes aegypti is the main mosquito, that has been known to cause the dengue fever and it produces four related viruses which include DEN-1, DEN-2
1. 1. Dengue Dengue is the most common arboviral (arthropod-transmitted) disease and it also position as the most important mosquito-borne viral disease in the world. Approximately 2.5 billion people living in tropical and sub-tropical regions are at a great risk of dengue infection, which is almost equal to about two-fifths of the human population (Gubler & Clark, 1995; WHO, 2009). There is an estimated 50-100 million infections occurring globally in each year, with 500,000 cases requiring hospitalization
The epidemiology of both dengue and West Nile Virus (WNV) are based on mosquito patterns and their interaction with human. Dengue has plagued nearly every continent and continues to be a major public health problem. WNV, on the other hand, is a relatively new human public health problem, especially in the US. It might be possible to model control efforts found effective against the globally distributed dengue for control of West Nile Virus right here in the US. I was in high school when WNV hit my
in tropic and subtropic regions, with around 100 million symptomatic new cases each year worldwide15. It is caused by any one of the four closely-related serotypes or viruses that is spread by multiple species of mosquitoes, in particular the Aedes aegypti 6,13. Signs and Symptoms The symptoms include high fever, severe headache, joint and muscle pain and a characteristic rash that resembles measles. In some cases the disease develops into a life-threatening condition called dengue hemorrhagic fever

Many mosquitos like these kill millions of humans a year by the spreading of viruses like the Mayaro, Dengue fever, yellow fever, Chikungunya, and Zika. The Aedes Aegypti, also known as the yellow fever mosquito
INTRODUCTION: It is often thought that bacteria are usually found on the surface and orifices of organisms. However, one particular genus of bacteria does not conform to this premise, Wolbachia. Wolbachia is a bacterium found within the cells of arthropods. In addition, it is estimated that Wolbachia is found in approximately 66% of all insects (Hilenboecker, 2008). Several studies have been conducted and indicate that the vast majority of arthropods are affected during the reproduction phases.

They are many species of mosquitoes namely 2700 species of mosquitoes have been reported the three most significant ones are Aedes, Anopheles and Culex.These mosquitoes play a major role in the transmission of various dreaded disesases. Mosquitoes have developed resistance against many of the commercially available repellants. These repellants on routine use cause various health
that not all insects are safe, many of mosquitoes transfer infections, but we were not concentrating on that since it was considered not a common issue. As a repercussion, people did not begin to react and notice that something wrong with them when Aedes mosquitoes began their attempt on ruining people’s social, physical and psychological lives by transferring a Zika virus to the once who are bitten.
experienced a significant decline in population size and others have had to completely adapt new behaviors to survive. However, there are some that have largely benefitted from this insect free world. The die off of major disease vectors such as Anopheles, Aedes, and Culex mosquitoes which carry malaria, yellow fever, and zika had lead initially lead to increased health
addition, during this infection one may feel a sense of shivering, chills and shaking due to the fact that the body’s immune system is trying to fight the infection, (WHO.2014). The fever itself is said to be caused through the bite of an infected aedes aegypti mosquito. This may cause fever because of the anti-coagulants in the mosquito’s saliva, which cause the blood to clot. Furthermore, fever is not the only effect of Chikungunya in
Zika Virus The Zika virus, has as of lately come to the forefront just as sudden as the Ebola virus outbreak, back in 2014. Currently, not much is known with certainty about Zika, however, it is speculated there is a link between it and congenital malformations seen in newborns and other brain involved ailments which have been compared with the demyelization as it is seen in Multiple Sclerosis. Discovery Zika virus or ZIKV, which is an Arbovirus of the flavivirus genus belonging
Personal Statement Adaptation: one of the most important characteristics of an evolving pathogen, and also one of the most valuable skills I learned from constant travel between countries and regions. As the daughter of a military pilot, moving into new “homes” every three to four years inevitably made education an uphill climb, but rich and unique global experiences forged a deep-seated drive to think and act on the level of international communities. Like flint against steel, this innate urge
Sally is amongst the most wonderful mothers I have ever known. She begins each morning – rain-or-shine, lively-or-sick – at three o’clock sharp, when the late night grasshopper chirps are mixed with those of the early birds’. Now, she doesn’t arrive at work until nine and only spend thirty minutes getting herself freshened-up, dressed, and fed. So where does all of her remaining time go? The short answer is: Sally is devoted to singlehandedly preparing her daughter for each day ahead. No lack of
pig, the New World was not identical to the trained animals associated with the Old World, nor did it have the viruses associated with the Old World’s small populations of humans and such associated animals as chickens, cattle, black rats, and Aedes aegypti mosquitoes. Among these germs were those that brought smallpox, measles, chickenpox, influenza, malaria, and yellow fever. The Columbian exchange of crops affected both the Old World and the New.
