The Impact of West Nile Virus on Humans (or Why We Should Worry)
West Nile virus can infect humans, but there are more drastic ways that it affects our lives. The virus normally lives in birds and is transmitted among them and other animals by mosquitoes. There is no other definite method of transmission, and people do not have to worry about contracting the virus through contact with infected humans or animals. Hundreds of species of birds and many mammals, including several endangered species, are vulnerable to the virus. Many domestic animals are also susceptible, but the virus does not create any symptoms in most of them. There is no way of getting rid of the virus once an animal has been infected, but a vaccine for horses has recently been approved by the USDA. There are also vaccines for preventing infection in humans being worked on by several companies.
West Nile virus can infect humans, but infection is not the only way that it affects our daily lives. Several other animal species can also become infected by the virus, so special care should be taken to protect our wildlife, our livestock, and even our pets.
West Nile virus is transmitted from birds to other animals through a vector, one of forty-three species of mosquito. Scientists have also found West Nile virus in ticks in Africa and Asia (Lee, 2003), but there has been no evidence that the ticks can also act as a vector for the virus. People cannot catch West Nile virus from any other animals, so becoming ill from the virus should not be the main concern of humans regarding the virus.
However, if a human does become infected with West Nile virus, it is unlikely that it will produce any symptoms. Usually, only people over the age of 50 or very young children are...

Almost no one on Earth has any immunity at all to this virus, which makes ordinary vaccines useless against it. The sudden spread of the virus into Europe foreshadows an epidemic development that could be worldwide. Ultimately, there is no way to protect ourselves against epidemics. They will keep disappearing and coming back in new forms.

The West Nile Virus first came to the U.S. public's attention following an outbreak in New York in August 1999 where eight patients has contracted ecephalitis from the virus. In the following four years the virus spread to almost all 48 contiguous states. In the United States cases were initially infrequent until 2002, when a massive outbreak occurred in the Mississippi River basin during August and September. As it has spread through the country, nearly 8,500 people have been diagnosed with the virus, which has lead to 189 deaths. The emergence of the new disease has been followed closely by the media and the government. Many areas that have experienced significant outbreaks of the Virus have occured have implem...
A disease is transmitted in one way or the other. Lyme disease is transmitted through a vector. The vector of the disease is an infected deer tick. The deer tick has to bite a person to spread the disease. When a deer tick bites a person (sucks blood), the Borrelia burgdoferi bacteria is transmitted into the persons body.

There are thing that make people more susceptible to contracting zoonotic diseases. Either it’s knowingly or unknowingly, humans are prone to the dangers of being direct targets of zoonotic diseases. Zoonotic diseases are transmittable in various ways weather through ingestion or direct contact. There are countless numbers of zoonotic diseases some more commonly known than others but all equally important. Preventing the contraction or spread of zoonotic diseases is easily manageable with medication and vaccines along with following small tips that not only protect humans but the animal population as well.
Dengue fever, also known as the “breakbone fever”, is a vector-borne viral disease endemic 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.

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 and causing 24,000 deaths (Halstead, 1988; WHO, 1997). Furthermore, the increasing populations in tropical and sub-tropical regions, making dengue as a global threat to public health (UNEP 2009; Holden, 2009).
