After years of tracking the virus and its origins, tests conducted on how it was transferred from host to host and how exactly the public in general can protect itself from deadly viruses established a research base for further studies. The New York West Nile epidemic brought a lot of attention to the forgotten lethal virus. The virus is carried by the common North American mosquito. Viruses have existed among us for many years, and cause many very deadly outbreaks all across the globe. The virus can rapidly spread throughout an area in no time; host-to-host it spreads like a wild fire.

This means that this disease will most likely be around for a long period of time, as the drugs developed will eventually become useless. Resistance to malaria drugs is a natural consequence of widespread use of the drug. This means that the drugs should not be used often, but if it spreads, they will have to be used more. To protect against this, the global authorities are trying to assure that the best drug used to fight it is only sold as a combination pill with other anti-malaria medicines.

However concern arises, because the possibility of the virus creating greater complications is likely. To prevent one from contracting the swine flu, he or she should get vaccinated. The main difference between the regular flu vaccine and the H1N1 flu vaccine is the components of which these vaccines are composed of. One should make the decision to get the swine flu vaccine based on one’s age and current medical condition.
India, being a malaria endemic zone, confronts this protozoan disease perennially. India’s wide-spread geography, ecological diversity and climatic variability make it an ideal place for malaria parasites and their vectors to sustain. The disease which was earlier confined only to rural areas has now taken different forms like urban, industrial, plains and forest malaria, thereby increasing national burden. Currently, about 95% of the 1.21 billion population of India is at risk of malarial infection [6, 7]. An estimated 1.5 million cases and 1000 deaths are attributed to malaria annually in this region[6, 8].

(3) Professor Donald Shepard from Brandeis University, who studied dengue fever while at Schneider Institutes for Health Policy, in his own opinion he explained that aedes aegytpi mosquitoes cannot fly very far therefore areas which are highly populated can be good places for transmission. Also poor areas with lack of reliable water and sewage systems are at risk of having Aedes aegytpi mosquitoes because of good breeding ground for them. (2) 2.5 billion People living in countries like the South East Asia, the Pacific islands, Latin America, the Caribbean islands and parts of Africa have had high issues associated with dengue fever. The World Health Organisation (WHO) has estimated about 50-100 million people are affected by the illness around the world.
About 35,000 people die each year. (Paul Tambyah-pg 6) More public education is needed so that the general population can identify symptoms and seek timely treatment. Getting the flu shot can really save the hassle of being infected. If someone has come down with this virus, stressing out about everyday things can irritate the immune system.

The intentions today are to cover the first found cases of West Nile Virus, the symptoms of West Nile Virus, and finally West Nile Virus' impact on the United States. Through the research here, the hope is that we can all have a better understanding of how West Nile Virus works. West Nile Virus gets its name from its birthplace in the West Nile District. According to (Gubler, Duane, Marfin, Anthony & Petersen, Lyle, 2003) it was in 1937 that Uganda had its first isolated case of West Nile Virus (para. 4).
Transmission and symptoms of Malaria Malaria is a vector-borne disease that is spread by the bite of a mosquito. According to National Institute of Allergy and Infectious Diseases (2014) “In 2013, 97 countries had ongoing malaria transmission, placing 3.4 billion people at risk for the disease. And in a globally connected world, even people living in the United States can be at risk. In 2011, nearly 2,000 people in this country were diagnosed with malaria—the highest number since 1971” (para. 2).
Terrorists groups have become smart and have used anthrax in letters so victims will become infected upon opening. The U.S. has since taken safety precautions to prevent attacks from happening in the future (History of Bioterrorism n.p.). Health care facilities are very concerned about the outbreak of a biological agent attack. Bioterrorism was a powerful deterrent to war because of its rareness, but now almost every country has biological weapons that could wipe ou... ... middle of paper ... ...vention Programs Justifiable? - Volume 3, Number 2-June 1997 - Emerging Infectious Disease Journal - CDC."
While Dengue fever has been present throughout the centuries, its potential impact as a public health crisis is still emerging. Dengue is a virus transmitted to humans by female mosquitoes. It has been suggested that the earliest account of dengue infection occurred in China dating back to 992 A.D. Approximately 2.5 billion people are at risk from dengue infection. Dengue is endemic to urban population where the virus is transmitted by the freshwater mosquito which is called Aedes aegypt.
