West Nile Virus Essay

West Nile Virus has emerged in recent years throughout the temporate zones of Europe and North America. Causing a variety of conditions in its hosts, the most serious manifestation of WN virus infection is fatal encephalitis (inflammation of the brain) in humans and horses, and many birds.

Individuals with mild symptoms of West Nile Virus make up about twenty percent of the populations of infected humans. This form of the disease is known as West Nile Fever. The symptoms of West Nile Fever include: fever, headache, tiredness, body aches, nausea, vomiting, swollen lymph glands, and a skin rash appearing on the back, chest or stomach. A headache and high fever are the most common indicators for a West Nile Virus infection. These mild symptoms can last anywhere from a few days to several weeks. (California Government, 2005).

The incidence is highest in late summer and early autumn, until the first hard frost does away with the mosquito population for that year. Birds and other animals (such as horses) are the usual reservoir for the infection, and they are involved in its dissemination. Initial viral symptoms may give way to high fever and neck stiffness (meningeal signs). However, as with most forms of encephalitis, it is the confusion and depressed levels of consciousness (stupor) that mark the infection as being of the brain (encephalitis) and not just the meninges. West Nile Virus is an acute central nervous disease (McCance & Huether, 2014).

The West Nile Virus is a virus that people can get from an infected mosquito bite. This virus disappeared and no one heard much of many people getting the virus for about 20 years. In the 1990´s there was a big comeback on the rise for the West Nile Virus. That also consisted of the infected bugs slowly but surely making their way to America from Africa, the Native country to this virus (Phillip).

The Iowa Department of Public Health has confirmed a rare case of disease caused by the Jamestown Canyon virus. In addition, there are two cases has been reported to the Iowa’s Health Department about West Nile Virus, which is also an illness spread by mosquitoes, along with Jamestown Canyon virus. According to the author, people who are infected by these two viruses will experience: “fever, headache, and flulike illness.” Luckily, however, “the patients who had Jamestown Canyon virus and West Nile virus are slowly recovering.”

Lower return crops such as corn, wheat, cotton and rice will bear the brunt of this whereas the higher return crops such as nuts, citrus and vine crops will be least affected (Kowalski, 2015).

The main point of the press release is to notify the public that the West Nile Virus has surfaced and is active. One of the sub-points is to inform the public of the current case and the number of cases over the years of people who have been infected with the West Nile Virus. Another sub-point is to give the description and signs of the West Nile Virus. Another sub-point is to notify the public where the West Nile Virus is coming from. Another sub-point what is causing the mosquitoes to breed and how to prevent the breeding of the mosquitoes to notify the public that there are two types of West Nile Virus. The West Nile encephalitis and the West Nile poliomyelitis are the two viruses the press release also notified the public of the signs and symptoms of the west Nile virus. What to do and who to contact once bitten the press release gives a statistic of number of cases from 2002 to 2011 (2012). The press release also notifies the public who is at the highest risk to becoming ill with this type of virus. The press release also gives other website to seek out more information regarding the West Nile Virus.

The Symptoms of Rocky Mountain spotted fever: Initial symptoms may include fever, nausea, vomiting, severe headache, muscle pain, and lack of appetite. The characteristic red, spotted rash of Rocky Mountain spotted fever is usually not seen until the sixth day or later after symptoms begin. As many as 10% to 15 % of patients may never develop a rash (Traveldoctor.com, 2015). Rocky Mountain spotted fever is treated with antibiotics. Signs of infection: It is normal for a bite or sting to result in redness of the affected area and minor swelling, but if a bite or sting becomes infected, a fever may develop or the redness or soreness may worsen.

Although most cases are relatively mild and include symptoms like a fever and skin rash, those with more severe cases can exhibit convulsions, muscle weakness, and paralysis. Some cases even prove fatal. There is no specific treatment for the virus, with most therapy coming under hospital oversight. In working to prevent the disease, several areas have taken to spraying against mosquitoes and recommended the

The Ebola Haemorrahagic Fever, or Ebola for short, was first recognized as a virus in 1967. The first breakout that caused the Ebola virus to be recognized was in Zaire with 318 people infected and 280 killed. There are five subtypes of the Ebola virus, but only four of them affect humans. There are the Ebola-Zaire, Ebola-Sudan, Ebola-Ivory Coast and the Ebola-Bundibugyo. The fifth one, the Ebola-Reston, only affects nonhuman primates. The Ebola-Zaire was recognized on August 26, 1976 with a 44 year old schoolteacher as the first reported case. The Ebola-Sudan virus was also recognized in 1976 and was thought to be that same as Ebola-Zaire and it is thought to have broken out in a cotton factory in the Sudan. The Ebola-Ivory Coast was
