Characteristics and Statistics of the Infectious Disease Dengue Fever
Dengue fever is an infectious disease that is conveyed by mosquitoes that ingest the virus from infected humans. An outbreak of infection is most likely to happen in warm, wet climates. The risk for acquiring dengue fever in the United States is rare, however the main cause of occurrence is to be imported from travelers from foreign countries. Most symptoms are non-life threatening, nevertheless it can become more severe leading to death if symptoms are uncontrolled.
Dengue fever is initiated by a virus that consists of a small single-strand of RNA with one of the four closely related dengue viruses: DENV 1, DENV 2, DENV 3, DENV 4(Centers for Disease Control and Prevention[CDC], 2012). According to the World Health Organization, “The related dengue virus belongs to the genus Flavivirus, family Flaviviridae” (WHO, 2009). Flaviviridae family incorporates viruses such as West Nile virus, dengue fever, tick-borne encephalitis virus, yellow fever virus, and others that may cause encephalitis. The word “flauvis” means “yellow” in Latin, which means “yellow fever”. These terms originated from its tendency to cause yellow jaundice in patients.
Humans are the primary reservoir for dengue and host the virus through their blood stream. The virus is transmitted by the bite of an infected mosquito. The CDC states, “Aedes aegyti is the most important transmitter or vector in the Western Hemisphere”(CDC, 2012). A female mosquito ingests the humans infected blood during feedi...

- 1. There exists seven distinct categories of biological agents which can cause infectious diseases. These agents are: a. Virus. They have an outer coat made of protein and have DNA or RNA core. They can only reproduce and grow in living cells. An example of a disease caused by virus is influenza- a respiratory illness that leads to the development of pneumonia. b. Bacteria. These are single-celled organisms with no nucleus. An example of a disease caused by these organisms is tuberculosis; a well-known chronic lung disease....

- This paper will cover the characteristics of meningococcal disease and the bacteria that cause it, Neisseria meningitides. Neisseria meningitides is a Gram-negative dipplococcus. It is a facultative anaerobe and is non-motile. The bacteria can live in a commensal relationship with the mucous membranes in the human nose (Peterson, n.d.). When grown in a colony (on a chocolate agar plate or a blood agar plate) it has a clearly defined edge, is round, smooth, moist and convex. As for color it is gray or colorless and opaque (CDC, n.d.).... [tags: bacteria, symptoms, dignosis]

- Brucella: Description of Organism: There are several species of Brucella found throughout the world. The majority of which are classified based on phenotypic characteristics and host preferences, despite nearly identical DNA sequences or genomes (Bosilkovski, “Micro”). The reasoning behind this classification is due to the fact that several Brucella species prefer a particular host, such as dogs or cattle. The Brucella species are some of the smallest bacteria in the world. Brucella species’ common characteristics include: gram negative, nonmotile (lack flagella), facultative intracellular, aerobic, lack capsule, lack spores, and are the second smallest gram negative organism to be obser...

- The human body is a complex and sophisticated machine in which all components must maintain an intricate balance to ensure optimal functioning. This balance at a specific set point is known as homeostasis. There are many homeostatic variables and the one I find most interesting is temperature, more specifically how our bodies respond to environmental and internal threats by means of thermoregulation. Many different syndromes such as heat stroke, neuroleptic malignant syndrome, malignant hyperthermia and fever can lead to elevation of body temperature.... [tags: Medical Research]

- Epidemiology of Tuberculosis World travel has become more commonplace and people are no longer destined to remain on a single continent. Travel’s ease and affordability has made the spread of disease easier. One of those diseases that is spread worldwide is tuberculosis (TB). Description of Tuberculosis Since ancient times Tuberculosis has been present, also known as Consumption. Despite current advanced medical screenings, diagnostics, and treatment methods, approximately one-third of the world’s population has been exposed and is infected with the organism (Mandal, 2014, para....

- Introduction: West Nile virus and Zika virus belong to Arbovirus group which are usually transmitted by mosquito, ticks or some other vectors. The growing concern regarding West Nile virus is not unexpected as people has seen the worst consequences of Zika virus. But as an Epidemiologist, any conclusion should be made in a systemic way base on previous data and background knowledge about the investigation. Being the same group member does not always make them equal deleterious. As we all know that not all the hepatitis virus causes hepatocellular carcinoma, few of them are very mild that they persist few days without leaving any long-term effect....

- History Francisella tularensis is a bacteria that is commonly referred to as Rabbit Fever. This microorganism is often known as this because the bacteria resides in mammals such as rabbits, squirrels and mice (UPMC Center for Health Security, 2013). There are many different components to this bacteria that make it unique. The microorganism F. tularensis is one that has very unique characteristics that make it responsible for being the kind of bacteria that it is. It is a gram-negative bacteria that occurs in coccobacillus form.... [tags: Bacteria, Immune system, Infectious disease]

Virally initiated illnesses typically cause a short duration of malaise depending upon the virulence of the pathogen. However, they are usually accompanied by secondary infection which can be from multiple origins, including but not limited to bacteria, fungi, other viruses, or even protozoa. Although there are no medications specifically for the treatment of MERs-CoV infections, antifungals, antibiotics, and antivirals can be used to reduce the incidence of the patient’s developing secondary infections....

The three leading infectious diseases that have evolved through the years are AIDS, Malaria and Tuberculosis. These diseases continue to cause thousands of deaths each year as these killers are silent, but very deadly.
