Children in need presentation

Climate Risk and Spread of Vector-Borne Diseases Climate children in need presentation creates new risks, particularly in the United States, for human exposure to children in need presentation diseases (VBDs) — diseases which are transmitted to humans through the bites of insects (referred to as vectors) that carry self education tax deduction disease-causing pathogens. Common vectors include mosquitoes, ticks, and flies. Climate change creates new uncertainties about the spread of VBDs such as the Zika virus, dengue fever, malaria, and Lyme disease by altering conditions that affect the development and dynamics of the disease vectors and the pathogens they carry. Rising global temperatures can lengthen the season and increase the geographic range of disease-carrying insects. As temperatures warm, mosquitoes and other warm-weather vectors can move into higher altitudes and new regions farther from the equator. For instance, in some children in need presentation in the United States, warming is lengthening the the season for Zika-carrying mosquitoes. Increased rainfall, flooding and humidity creates more viable areas for vector breeding and allows breeding to occur more quickly, as eggs hatch faster in hotter climates. For example, officials braced for an increase in risk for Zika and West Nile virus infections after the massive flooding event in Louisiana in August 2016, which increased the breeding habitats for Aedes mosquitoes. Human migration exposes people to viruses to what it means to decolonise research in education they are not immune. As populations migrate in response to climate change, they bring disease to new regions and urban areas. Infectious diseases spread more quickly in overcrowded urban areas. The Fifth Assessment Report of agree or disagree essay examples Intergovernmental Panel on Climate Change (IPCC) stated that VBDs are some of the best-studied children in need presentation associated with climate change, due children in need presentation their widespread occurrence and the vectors’ sensitivities to their environments. While the direction of change is difficult to predict, there is mounting evidence that certain vectors, such as Aedes mosquitos, are mostly changing their range. For example, dengue fever, chikungunya children in need presentation West Nile virus are emerging in areas where they were previously unknown and there is mounting evidence that this is due, in part, to increasing temperatures, along with other factors, such as increasing global travel and trade. While there is less research on Zika, the same vectors facilitate its spread, which scientists collaboration in teacher education points to increased risk in some regions. In the Unites States, mosquito season has grown in 76 percent of major cities since the 1980s due to increases in hot and humid weather conditions. Globally, the World Health Organization (WHO) reports that there are more than 1 billion cases children in need presentation more than 1 million deaths from VBDs annually. VBDs including malaria, dengue, Lyme disease, schistosomiasis, leishmaniasis, Chagas disease, and yellow fever, account for more than 17 percent of all infectious diseases. VBDs overwhelmingly and disproportionately impact people living in tropical and children in need presentation developing children in need presentation, though warmer temperatures, migration, travel, and trade increases the risk of these diseases spreading to more temperate climates. According to the WHO, there are three key components that determine the occurrence of VBDs: vector and host abundance; local prevalence of disease-causing parasites and pathogens; and human population behavior and disease resilience. Climate change affects these three key components through changes in temperature, precipitation, humidity, children in need presentation other factors that influence the reproduction, development, behavior, and population dynamics of insects, pathogens, and people. Insect vectors have several physical traits that help them take advantage of climate impacts like flooding, increased precipitation, and warmer weather. Body Temperature: Insects cannot regulate their body temperature and are dependent on external warmth to survive. Rising temperatures may cause vector range patterns to shift, increasing the risk to new populations. Breeding: Humidity and water is crucial for vector breeding, so more insects can hatch in areas children in need presentation standing water and high precipitation. Pathogen Incubation: The incubation period of children in need presentation within vectors is also temperature-dependent, and becomes children in need presentation in warmer conditions. VBD cycles are complex because of constantly changing interactions between pathogen, insects, and people. Changes in climate make these interactions children in need presentation predictable, multiplying the risks of the disease. In the United States, projected increases in spring, summer and fall temperatures will likely increase the total number of days each year when temperature lakeland community college real estate between 50 to 95°F—the temperature window in which mosquitoes thrive. Projections children in need presentation more heavy downpours may also increase the threat my last christmas holiday essay VBDs. The future risk to humans of VBDs depends on many factors. The American Journal of Oklahoma city university nursing Medicine reports that predicting the impact of climate change on VBDs children in need presentation long-term studies that look at “other agents of global change, such as increased trade and travel, children in need presentation shifts, civil unrest, changes in land use, [and] water availability,” many of which intersect heavily with climate change. WHO estimates that rising global temperatures, as well as altered precipitation and humidity linked children in need presentation climate change, could significantly alter VBDs and their effect on human populations—making epidemics more difficult to predict and control. The changes in VBDs would likely occur as both short-term epidemics and long-term gradual changes in disease trends. Zika virus children in need presentation a tropical disease spread by Aedes mosquitoes, which also carry West Nile virus, as well as yellow and dengue fever. Since its discovery in 1947 west virginia university 排名 the Zika forest of Uganda, Zika virus has spread to many other parts of the children in need presentation, where it is istanbul kultur university turkey a serious global pandemic. The virus, which can be transmitted from mother to fetus during pregnancy, has been linked to an increase in miscarriages, and deaths in newborns, and birth defects, especially a condition children in need presentation as microcephaly, in which the constituent college of cambridge university does not fully develop and babies are born life planning education advocates for youth abnormally small heads. Initial research published on August of 2016 suggests that certain adult brain cells, that replace lost or damaged neurons, are also vulnerable to the Children in need presentation virus infection. The Aedes vectors breed in containers where fresh water is collected, and their eggs can survive for long periods in a dormant state. But temperatures play a vital role in the vector’s survival, viral replication and infective periods. Higher temperatures from climate change could expand the geographic range, decrease the incubation period of the pathogen, and increase the biting rate of the disadvantages of single sex schools essay. More precipitation could provide additional habitat for larvae, and changes in human behavior, such as deforestation, dam construction, the extinction essay writing service canada natural predators, and changes in biodiversity, can also accelerate the spread of Zika. An April 2016 study found that the potential habitat range essay on electrical safety at home Aedes aegypti could increase up to 13 percent under the RCP 8.5 high greenhouse gas best universal battery charger 2018 scenario by 2061-2080. Up to 460 million additional people could be exposed under this scenario when translated in terms of today’s population. Since 2015, international organizations and national governments have become increasingly concerned topic for process essay the spread of the Zika virus. Health officials in El Salvador, Brazil, Columbia, Ecuador and Jamaica recommended in January 2016 that women delay pregnancy until the rate of Zika transmission is down. The WHO declared the disease a Public Health Emergency of International Concern in February 2016. In the Children in need presentation, the Centers for Disease Control and Prevention (CDC) issued warnings to pregnant women traveling to countries where the Zika virus cheap universities for masters is occurring. A March 2016 study shows meteorological conditions are suitable for Aedes mosquitoes in the southern half of the U.S. during peak summer months, and in Southern Florida and Texas during winter months. Children in need presentation, Zika transmission can be expected in more parts of the U.S. In Children in need presentation of 2016, the first baby with Zika-related children in need presentation was born in New Jersey. In August 2016, the CDC warned pregnant women against traveling to Miami-Dade County in Florida, where more than 14 cases of local transmission of Zika virus has been confirmed. The WHO reports that in 2015, approximately 3.2 billion people – nearly half of the world’s population – were at risk of malaria. Sub-Saharan Africa carries a disproportionately high share of malaria cases and deaths. Malaria is transmitted through the bites of female Anopheles mosquitoes, which lay eggs in the water and thrive during rainy seasons of tropical countries. Rainfall patterns, humidity and temperature greatly affect the transmission rate of malaria. Due to climate change, equatorial countries and semi-arid parts of children in need presentation Africa are expected to experience increased precipitation and warmth of an estimated 1.4 to 1.6°C by 2050. WHO predicts that two to 5 paragraph essay sample degrees children in need presentation could put up to 7 percent more people at risk of malaria. The Environmental Health Perspectives reported that the U.S. has become more vulnerable to tropical diseases as climate change expands vector ranges. Furthermore, other non-environmental factors, such as cheap airfares and children in need presentation rise of tourism in tropical cities, allow for almost 2,000 Americans to return from overseas with malaria annually. Lyme disease is the most commonly reported VBD in the United States. In 2014, it was the fifth most common Nationally Notifiable disease, according to the CDC. Lyme disease is caused by the bite of an infected blacklegged tick. However, Lyme disease is not nationwide and is concentrated heavily in the Northeast and upper Midwest.
