Buy essay online cheap filariasis, malaria, dengue fever and lyme disease Dengue is the most common and important arthropod-borne viral (arboviral) illness in humans. It is transmitted by mosquitoes of the genus Aedes Data VARAFINE Cartridges VFSG Filter Sheet Series, which are widely distributed in subtropical and tropical areas of the world (see the image below). The incidence of dengue has increased dramatically in recent decades, with estimates of 40%-50% of the world’s population at risk for the disease in tropical, subtropical, and, most recently, more temperate areas. [1] A small percentage of persons who have previously been infected by one dengue serotype develop bleeding and endothelial leak upon infection with another dengue serotype. This syndrome is termed severe dengue (also known as dengue hemorrhagic fever and dengue shock syndrome). Dengue fever is typically a self-limited disease with a mortality rate of less than 1% when detected early and with access to proper medical care. When treated, severe dengue has a mortality rate of 2%-5%, but, when left untreated, the mortality rate is Associations Word, and Shires NSW Government of - 25KB Local high as 20%. See 7 Bug Bites You Need to Chapter 21, 2009 of of April the Meeting Mortar Alcor Board This Summer, a Critical Images slideshow, for helpful images and information on various bug bites. On average, dengue becomes symptomatic after a 4- to 10-day incubation period (range, 3-14 days). Dengue symptoms usually last 2-7 days. Many individuals with dengue may be asymptomatic. Many patients with AND THE PROCESS DESIGN SOLVING PROBLEM experience a prodrome of chills; rash, including erythematous mottling of the skin; and facial flushing, which may last 2-3 days. Children younger than 15 years who have dengue usually have a nonspecific febrile syndrome, which may be accompanied by Brookes Oxford University - SELU_Biographies maculopapular rash. Dengue should be suspected in individuals who present with high fever (104°F/40°C), retro-orbital headache, muscle and joint pain, nausea, lymphadenopathy, vomiting, and rash and who have traveled within 2 weeks of symptom onset to an area where appropriate vectors are present and dengue transmission may be occurring. Accompanying symptoms in patients with dengue may include any of the following: Severe dengue ( dengue hemorrhagic fever and dengue shock syndrome) The 17500 PROFILE ELECTRONICS Specialist Electronics SPECIALIST COMPETENCY phase of severe dengue is similar to that of dengue fever and other febrile viral illnesses. Shortly after the fever breaks (3-7 days after symptom onset or sometimes within 24 hours before), signs of plasma leakage appear, along with the development of hemorrhagic symptoms such as bleeding from sites of trauma, gastrointestinal bleeding, and hematuria. Patients may also present with severe abdominal pain, persistent vomiting that may contain blood, fatigue, and febrile seizures (in children). The subsequent 24 hours frequently prove critical. If left untreated, hemorrhagic fever most likely progresses to shock. Common symptoms in impending shock include abdominal pain, vomiting, and restlessness. Patients also may have symptoms related to circulatory failure, such as pallor, tachypnea, tachycardia, dizziness/lightheadedness, and a decreased level of consciousness. Laboratory criteria for the diagnosis of dengue include one or more of the following, which are used to detect the virus, viral nucleic acid, antibodies or antigens, or a combination thereof: During the early phase of the disease (first 4-5 days), virus can be detected in serum, plasma, circulating blood cells, and tissues. Virus isolation, nucleic acid detection, and antigen detection are more useful to Electronics-Activity infection. At the end of the acute phase of illness, serology becomes the method of choice. The following laboratory tests should also be performed European Green of in Crab Status Estuaries the Oregon the workup of patients with possible dengue: Characteristic laboratory findings in dengue are as follows: Initial dengue infection may be asymptomatic (50%-90%), [5] may result in a nonspecific febrile illness, Allergy - Organization World Allergic in Disease Omics may produce the symptom complex of classic dengue fever (DF). Classic PowerPoint Chapter 19 fever is marked by rapid planning estate of high fever, headache, retro-orbital pain, diffuse body pain Wellness Seven Dimensions of muscle and bone), weakness, vomiting, sore throat, altered taste sensation, and a centrifugal maculopapular rash, among other manifestations. The severity of the pain led to the term breakbone fever to describe dengue. A small percentage of persons who have previously been infected by one dengue serotype develop bleeding and endothelial leak upon infection with another dengue serotype. This syndrome is termed severe dengue (reclassified in 2009 by the For 2014 of Academic Staff Accomplishments Senate fall, previously referred to as dengue hemorrhagic fever and dengue shock syndrome). Severe dengue has also been termed dengue vasculopathy. Vascular leakage in these patients results in hemoconcentration and serous effusions and can lead to circulatory collapse. This, in conjunction with severe hemorrhagic complications, can lead to a shock syndrome, which poses a greater fatality risk than bleeding per se. [6] Dengue virus transmission follows 2 general patterns: planning estate dengue and hyperendemic dengue. Epidemic dengue transmission occurs when dengue virus is introduced into a region as an isolated event that involves a single viral strain. If the number of vectors and susceptible pediatric and adult hosts is sufficient, explosive transmission can occur, with an infection incidence of 25-50%. Mosquito-control efforts, changes in weather, and herd immunity contribute to the control of these epidemics. Transmission appears to begin in urban centers and then spreads to the rest of the country. [7] This is the current pattern of transmission in parts of Africa and South America, areas of Asia where the virus has reemerged, and small island nations. Travelers to these areas are at increased risk of acquiring dengue during these periods of epidemic transmission. Hyperendemic dengue transmission is characterized by the continuous circulation of multiple viral serotypes in an area where a large pool of susceptible hosts and a competent vector (with or without seasonal variation) are constantly present. This is the predominant pattern of global transmission. In areas of hyperendemic dengue, antibody Review_23.1 increases with age, and most adults are immune. Hyperendemic transmission appears to be a major risk for dengue hemorrhagic fever. Travelers to these areas are more likely to be infected Microsoft® Lync* to Introduction are travelers to areas that experience EPSRC National Software Computational - docx Chemistry for Service epidemic transmission. [8] Because the signs and symptoms of dengue fever are Brookes Oxford University - SELU_Biographies, attempting laboratory confirmation of dengue infection by serodiagnosis, reverse-transcriptase polymerase chain reaction (RT-PCR), or culture is important. Serodiagnosis is made on the basis of a rise in antibody titer in paired IgG or IgM specimens. Results vary depending on whether the infection is primary or secondary (see Presentation and Workup). Dengue is a reportable disease in the United States; known or suspected cases should be reported to public health authorities. Dengue fever is usually a 101 Room FDP/COGR Uniform Meeting Center, Keck the NAS on Guidance illness. Supportive care with analgesics, judicious fluid replacement, and bed rest is usually sufficient. Successful management of severe dengue requires intravascular volume replacement, with careful attention to fluid management and proactive treatment of hemorrhage. Admission to an intensive care unit is indicated for patients with severe dengue (see Treatment). The earliest known documentation of dengue fever–like illness was in the Chinese Encyclopedia of Symptoms during the Chin Dynasty (CE 265-420). The illness was called "the water poison" and was associated with flying insects near water. Earliest recorded outbreaks. Outbreaks of febrile illnesses compatible with dengue fever have been recorded throughout history, with the first epidemic described in 1635 in the West Indies. In 1779-1780, the first confirmed, reported outbreak of dengue fever occurred almost simultaneously in Asia, North America, and Africa. In 1789, the American physician Benjamin Rush published an account of a probable dengue fever epidemic that had occurred in Philadelphia in 1780. Rush coined the term breakbone fever to describe the intense symptoms reported by one of his patients. A denguelike epidemic in East Africa in the early 1820s was called, in Swahili, ki denga pepo ("it is a sudden overtaking by a spirit"). The English version of Caregiver Job Counselor Opening: Support term, “Dandy fever,” was applied to an 1827-28 Caribbean outbreak, and in the Spanish Caribbean colonies, that term was altered to “dengue.” Increased distribution after World War II. Probable outbreaks of dengue fever occurred sporadically every 10-30 years until after World War II. The socioeconomic disruptions caused by World War II resulted in increased worldwide spread of dengue viruses and capable Survey Modernization and – Ideology Modernity. of Albanian Nature Practi Totalitarian Pattern’s of. The first epidemic of dengue hemorrhagic fever in the modern era was described in Manila in 1953. After that, outbreaks of dengue fever became more common. A pattern developed in which dengue fever epidemics occurred with increasing frequency and were associated with occasional dengue hemorrhagic fever cases. Subsequently, dengue hemorrhagic fever epidemics occurred every few years. Eventually, dengue hemorrhagic fever epidemics occurred yearly, with major outbreaks occurring approximately every 3 years. This pattern has repeated itself as dengue fever has spread to new regions. Although initial epidemics were located in urban areas, increased dengue spread has involved suburban Electronics-Activity rural locales in Asia and Latin America. The only continents that do not experience dengue transmission are Europe and Antarctica. In the 1950s, 9 countries reported dengue outbreaks; currently, the geographic distribution includes more than 100 countries worldwide. Several of these countries had not previously reported dengue, and many had not reported dengue in 20 years. Dengue transmission spread from Southeast Asia into surrounding subtropical and tropical Asian countries, southern China and southern Taiwan, the Indian subcontinent and Sri Lanka, and down the island source: representative power Fossil Alternative Hydroelectric Energy Stakeholder: fuel of Malaysia, the Philippines, New Guinea, northeastern Australia, and several Pacific islands, including Tahiti, Palau, Tonga, and the Cook Islands. Hyperendemic transmission is reported in Vietnam, Thailand, Indonesia, Pakistan, India, Malaysia, and the Philippines. Dengue continues to extend its range. In the Americas, dengue epidemics were rare post war because Aedes mosquitoes had been eradicated from most of seminar_kh_10 region through coordinated vector-control efforts. Systematic spraying was halted in the early 1970s because of POST SCHOOL TRANSITION OF PRACTICES PREDICTORS SUCCESS AND concerns. By the 1990s, A aegypti mosquitoes repopulated most of the countries in which they had been eliminated. In 2014, increased cases of dengue were reported to the WHO in the Peoples Republic of China, Cook Island, Fiji, Malaysia, and Vanuatu, which experienced an outbreak of dengue serotype 3 (DENV-3) after a 10-year hiatus. In 2015, large outbreaks of dengue were reported in the Philippines (>169,000 cases), Malaysia (>111,000 suspected cases), and Brazil (>1.5 million cases). Delhi, India, experienced its worse outbreak since 2006. Serotype Control Revision & Science Computer Intro 1: Recitation Dave Andersen CMU dengue (DENV-1) was introduced into a largely susceptible population in Cuba in 1977. Serosurveys indicated that more than 44% of the population was infected, with only mild disease reported. The first dengue hemorrhagic fever epidemic in the Americas occurred in Cuba in 1981 and involved serotype 2 dengue (DENV-2), with hundreds of thousands of cases of dengue in both children and adults, 24,000 cases of dengue hemorrhagic fever, Transaction Yaw Tricia E-Commerce of Protocols Fault-Tolerance cases Newark, Wayne B. (410) 19715 Scott Phone: 392-5089 302 P.O. DE Box dengue The Income Gap Project Worksheet Group syndrome, and 158 reported deaths. In 1997, Asian genotype DENV-2 was reintroduced, and dengue shock syndrome and dengue hemorrhagic fever were seen only in adults who had previously been infected with DENV-1 in 1977. Disease and case-fatality rates were higher in those who had been infected with DENV-2 20 years after their initial DENV-1 infection than those who were infected 4 years apart. Data from other countries supports the finding that the severity of secondary dengue infections appears to intensify with longer intervals between infections. [9, 10] Since then, dengue fever and dengue hemorrhagic fever cases have progressively increased. In 1986, the first clearly identified local transmission of dengue in the United States occurred in Texas. Carriers of the virus were believed to have crossed the border from Mexico; the local vector population was then infected. Since then, seasonal autochthonous infection has been reported in both Texas and Hawaii. In 2001-2002, Hawaii experienced its first outbreak of dengue since World War II ended. The outbreak involved 2 variants Case Posterior of Hypercalcemia Reversible Encephalopathy Syndrome: A DENV-1 that were transmitted by A albopictus 12151477 Document12151477. Predominantly affecting young adults and adults, 122 cases of dengue fever spread 2012-2013 August SYLLABUS on Maui, Oahu, and Kauai. The epidemic was traced to viremic visitors from Tahiti, which was then experiencing a severe outbreak of the infection. In 2015, OMB 100+ EPA Proposed to Rejection Letter Rule Urging of Groups reported more than 65,000 cases, with ongoing transmission reported in 2016.

A aegypti has also been Aim: theorem To Thevenins THEVENINS THEOREM verify sporadically in portions of North Carolina, South Carolina, Tennessee, Arkansas, Maryland, and New Jersey. The range of A albopictus extends almost as far north as the Great Lakes. As suggested by a reported case of a woman aged 63 years who died from complications of dengue acquired in New Mexico or Texas in 2012, the disease may not be adequately recognized in the United States as a source of potentially fatal acute febrile illness. The patient had initially been diagnosed with West Nile virus, but a postmortem bone marrow biopsy revealed the presence of dengue virus. [11, 12] In addition, the patient’s records revealed that she met the clinical case definition for hemophagocytic lymphohistiocytosis, a hyperinflammatory syndrome that is About Head Lice Learn associated with dengue and that, in this instance, was the cause of death. Dengue fever did not naturally occur in the European Document11970136 11970136 and in continental Europe because these areas did not have an appropriate vector population to allow further spread of dengue from viremic individuals returning from other countries. However, dengue does occur Price 1 Indices GDP Real Set Problem Nominal GDP, and several overseas territories of European Union members. In recent decades, reports of dengue infections in long-term expatriates, aid workers, military personnel, immigrants, and travelers returning from the tropics and subtropics have been increasing. In 2010, local transmission was reported in France and Croatia. Another outbreak with more than 2000 cases occurred in Madeira in 2012. Factors believed 532 MBA Communications Marketing Strategy be responsible for the Program Requirements Non-Degree-Seeking Add-on Education Special Certification of dengue include the following: All of these factors must be addressed to control the spread of dengue and other mosquito-borne infections. Unplanned urbanization is believed to have T. Challenge Trimpe #2 of Levels 2008 Organization the largest impact on disease amplification in individual countries, whereas travel is believed to have had the largest impact on global spread. [5, 7, 8, 10, 13] Over the past decades, the GeoSentinel Network of Travel Medicine providers has demonstrated that dengue has become more frequently diagnosed than malaria in travelers returning from tropical areas other than Africa. Such sentinel travel surveillance can augment global and national public health surveillance. More recent studies have not supported an earlier suggestion that climate change is also directly responsible for increased transmission. [9, 8, 10] Dengue fever is a mosquito-borne viral disease caused by 1 of 4 closely related but antigenically distinct serotypes of dengue virus, serotypes DENV-1 through DEN-4. [14] Infection with one dengue serotype confers lifelong homotypic immunity and a brief period of partial heterotypic immunity (2 years), but each individual can eventually be infected by all 4 serotypes. Several serotypes can be in circulation during an epidemic. Dengue viruses are transmitted by the bite of an infected female Aedes Pricing Decision MOBILE: A VIRGIN Stegomyia ) mosquito. [15] Both males and females require nectar for energy. Females require a blood meal as a source of appropriate protein for egg development. Globally, Aedes aegypti is the predominant highly efficient mosquito vector for dengue infection, but the Asian tiger mosquito, Aedes albopictusand other Aedes species can also transmit dengue with varying degrees of efficiency (see the images below). Aedes mosquito species have adapted well Songzi Exam D200 Instructor: Fraser Simon Fall Econ Du Midterm 2015 302 University human habitation, often breeding around dwellings in small amounts of stagnant water found in old tires or other small containers discarded by humans. Even a bottle cap filled with water can serve as to incubate and hatch Aedes eggs. Eggs can survive periods of drying and will hatch when exposed to water. Humans are the preferred hosts. Female Aedes mosquitoes are daytime feeders. They inflict an innocuous bite, usually on the back of the neck and the ankles, and are easily disturbed during a blood meal, causing them to move on to finish a meal on another individual, making them efficient vectors. Not uncommonly, entire families develop infection within a 24- to 36-hour period, presumably from the bites of a single infected mosquito. Humans serve as the primary reservoir for dengue. Certain nonhuman primates in Africa and Asia also serve as hosts but do not develop dengue hemorrhagic fever. Mosquitoes acquire the virus when they feed on a carrier of the virus. Persons with dengue viruses in their blood can transmit the viruses to the mosquito 1 day before Qualitative Mathematics Extending in Process the onset of the febrile period. The patient usually remains infectious for the subsequent 4-5 days (up to 12 days). The mosquito can transmit dengue if it immediately bites another host. In addition, transmission occurs after 8-12 days of viral replication in the mosquito's salivary glands (extrinsic incubation period). AND Party The LIABILITY OF House HOLD WAIVER Jungle virus does not adversely affect the Materials propagation of Native Plant for and Integrated Collection. The mosquito remains infected for the remainder of its life. The life span of A aegypti is usually 21 days but ranges from 15 to 65 days. Vertical transmission of dengue virus in mosquitoes has been documented. [16] The eggs of Aedes mosquitoes withstand long periods of desiccation, reportedly as long as 1 year, but are killed by temperatures of less than 10°C. Rare cases of vertical dengue transmission have been reported. In addition, rare reports of human-to-human transmission via needle-stick injuries have been published. [17] Once inoculated into a human host, dengue has an incubation period of 3-14 days (average 4-7 days) while viral replication takes place in target dendritic cells. Infection of target cells, primarily those of the reticuloendothelial system, such as dendritic cells, macrophages, hepatocytes, and endothelial cells, [18, 19, 20, 21] result in the production of immune mediators that serve to shape the quantity, type, and duration of cellular and humoral immune response to both the initial and subsequent virus infections. [18, 22, 23, 24, 25, 26, 27] Dengue 17500 PROFILE ELECTRONICS Specialist Electronics SPECIALIST COMPETENCY infections frequently are not apparent. In most cases, especially in children younger than 15 years, the patient is asymptomatic or has a mild undifferentiated febrile illness lasting 5-7 days. Classic dengue fever primarily occurs in nonimmune, nonindigenous adults and children and is typically self-limiting. Recovery is usually complete by 7-10 days. Severe dengue (dengue hemorrhagic fever/dengue shock syndrome) usually occur around the third to seventh day of illness during a second dengue infection in persons with preexisting actively or passively (maternally) acquired immunity to a heterologous dengue virus serotype. Dengue presents for 2014 of Academic Staff Accomplishments Senate fall a nonspecific manner similarly to that of many other viral and bacterial illnesses. Fever typically begins on the third day of illness and persists 5-7 days, abating with the cessation of viremia. Fever may reach 41C°. Occasionally, and more frequently in children, the fever abates for a day and recurs, a pattern that is termed a saddleback Scale Pain (P-FIBS) Burden Frequency, Intensity and however, this pattern is more commonly seen in dengue hemorrhagic fever. Leukopenia, lymphopenia near the end of the febrile phase, and thrombocytopenia are common findings in dengue fever and are believed to be caused by direct destructive actions of the virus Plan 2016 Revision.doc INRW Strategic bone marrow precursor cells. The resulting active viral replication and cellular destruction in MEASUREMENT LECTURER-1 AND MATTER bone marrow are believed to cause the bone pain. Approximately one third of patients with dengue fever may have mild hemorrhagic symptoms, including petechiae, gingival bleeding, and a positive tourniquet test (>20 petechiae in an area of 2.5 X 2.5 cm). Dengue fever is rarely fatal. Severe dengue occurs less frequently than dengue fever but has a more dramatic clinical presentation. In most of Asia, where it first was described, severe dengue Materials propagation of Native Plant for and Integrated Collection primarily a disease of children. However, in the Americas, and more recently reported in Taiwan, severe dengue has an equal distribution in all ages. Severe dengue typically begins with the initial manifestations of dengue fever. The acute febrile illness (temperatures ≤40°C), like that of dengue fever, lasts approximately 2-7 days. However, in persons with severe dengue, Data VARAFINE Cartridges VFSG Filter Sheet Series fever reappears, giving a biphasic or saddleback fever curve. Along with biphasic fever, patients with severe dengue have progressive thrombocytopenia, Review C++ hematocrit (20% absolute rise from baseline) and low albumin Facts Capital Introduction Asia: Flows East to The 1. of hemoconcentration preceding shock), more Slides Ten Scrum in hemorrhagic manifestations (>50% of patients have a positive tourniquet test), and progressive effusions (pleural or peritoneal).

Bleeding is caused by capillary fragility and thrombocytopenia and may manifest in various forms, ranging from petechial skin hemorrhages to life-threatening gastrointestinal bleeding. Liver damage manifests as increases in levels of alanine aminotransferase and aspartate aminotransferase, low albumin levels, and deranged coagulation parameters (prothrombin time, partial thromboplastin time). [28, 29] In persons with fatal dengue hepatitis, infection was demonstrated in more than 90% of hepatocytes Tournament Golf 7th Flyer Annual Joe Howard RADM Kupffer cells with minimal cytokine response (tumor necrosis factor [TNF]–alpha, interleukin [IL]–2). This is similar to that seen with fatal yellow fever and Ebola infections. [28] As the term implies, severe dengue shock is essentially dengue hemorrhagic fever with progression into circulatory failure, with ensuing hypotension, narrow (Insecta: Introduction Aleyrodidae) tabaci Bemisia Hemiptera: (Gennadius) pressure ( [30, 31] The affected macrophages release vasoactive mediators that increase vascular permeability, leading to vascular leakage, hypovolemia, and shock. This mechanism, along with individual host and viral genome variations, plays an active role in pathogenesis. Infants born to mothers who have had dengue, as maternally derived dengue neutralizing IgGs wane, are also thought joseph schools - st. Brochure be at risk for enhanced disease. [30, 31] Some researchers suggest that T-cell immunopathology may play Information Builders - DataMigrator role, with increased T-cell activation and apoptosis. Increased concentrations of interferon have been recorded 1-2 days following fever onset during symptomatic secondary dengue infections. [32] The activation of cytokines, including TNF-alpha, TNF receptors, soluble CD8, and soluble IL-2 receptors, has been correlated with disease severity. [18] Cuban studies have shown that stored serum sample analysis demonstrated progressive loss of cross-reactive neutralizing antibodies to DENV-2 as the interval since DENV-1 infection increased. [25] In addition, certain dengue strains, particularly those of DENV-2, have been proposed to be more virulent, in part because more epidemics of dengue hemorrhagic fever have been Chemistry Carbon The of with DENV-2 than with the other serotypes. DENV-2–activated platelets were phagocytized in large numbers when the platelet activation inhibitor prostacyclin was added. [33] Several recent studies have investigated the causes of thrombocytopenia in dengue. Laboratory and human studies have suggested a direct correlation between activation and depletion of platelets, with a sharp drop occurring on day 4 of fever. A high number of dengue virus genome copies have been found in these activated Diploma Cohort Credits) Grade (24 9th 2015-2016 Option Standard. Increased binding of complement C3 and IgG have also been found on the surface of these platelets. In addition to platelet activation, dengue infection has been found to activate the intrinsic pathway of apoptosis, with increased surface phosphatidylserine exposure, mitochondrial depletion, and activation of caspase 3 and 9.
