Avian influenza is a highly contagious disease caused by influenza A viruses antibiotics for uti nitrofurantoin purchase zyvox overnight, affecting many species of birds infection japanese movie purchase 600 mg zyvox with visa. These hosts and their viruses have become well-adapted to each other over time and infection does not usually cause overt disease bacteria at 8 degrees order generic zyvox line. That said, recent studies indicate that some behavioural changes may occur in response to infection i. These low pathogenic viruses replicate mainly in the intestinal tract (and also in the respiratory tract) of aquatic birds. Mammals – most commonly pigs but also humans – can be infected with influenza A viruses. Broader public health concerns relate to the potential for these, or other, avian influenza viruses to mutate or reassort to create a pandemic strain (i. Viruses belonging to the H5 and H7 subtypes (in contrast to other virus subtypes), may become highly pathogenic. Species affected Poultry are very susceptible to avian influenza infection and the disease causes high mortality and/or loss of producitvity. Humans are, in general, relatively resistant to avian influenza viruses, but in some individuals infection can be severe. Geographic distribution Avian influenza is reported globally, including in the Americas, Asia, Middle East, Europe and Africa. How is the disease The viruses have evolved to be transmitted by the faeco-oral and/or transmitted to animals? How does the disease For poultry, infection is primarily spread through the movement and trade of spread between groups poultry and poultry products locally, nationally and internationally. The practice of outdoor poultry production, including grazing domestic ducks in rice paddies, is considered to be one way in which disease can easily transfer between wild and domestic birds (in both directions). The relative importance of these routes is often difficult to determine (and will differ by situation, location and time period). Scavenging and predatory birds and mammals may acquire infection by ingesting infected birds. How is the disease Humans can become infected via close contact with infected birds or inhalation transmitted to humans? However, situations where there is exposure to high levels of virus, such as during disease control activities or butchering or preparation of infected birds, are of higher risk and appropriate hygiene precautions should always be taken, including use of personal protective equipment. For waterbirds, other conditions such as lead poisoning can also cause these signs although this is more likely to be a longer term illness i. Symptoms include conjunctivitis, ‘flu-like symptoms (including fever), coughing and shortness of breath, diarrhoea, vomiting, and abdominal pain. Public health authorities should be contacted if there is suspicion of human infection. Livestock Poor hygiene and biosecurity, overstocking, and mixing of different animals greatly increases the risk of both introduction and the spread of infection. Primary management efforts must be focused on limiting the opportunity for infection to be introduced. The main recommended courses of action following an outbreak of disease are culling of domestic poultry flocks, implementation of movement restrictions and cleansing and disinfection of affected premises. Biosecurity High standards of biosecurity will help prevent introduction of virus: Reduce/prevent contact with wild birds (for small scale poultry holders this may involve feeding birds under cover). Have disinfection facilities for hands, footwear, clothing, equipment and vehicles/trailers on entering or leaving areas with poultry and after contact with animals. Wear protective clothing and footwear, either disposable or if re-useable, easily disinfected (e.

Investment in chronic disease prevention programmes is essential for many low and middle income countries struggling to reduce poverty. Chronic diseases and poverty This chapter has illustrated some of the relationships between chronic diseases and poverty. As a country develops economically, chronic disease risks may ﬁrst increase among the wealthy but soon concentrate among the poor. In almost all countries poverty increases the risk of developing a chronic disease, and everywhere increases the chances of developing complications and dying prematurely. Chronic diseases can cause individu- als and families to fall into poverty and create a down- ward spiral of worsening poverty and disease. As the next chapter shows, chronic diseases also hinder the macroeconomic development of many countries. Third, effective interventions the “full costs” or welfare losses of chronic disease are assessed. In agricultural communities, the pattern of planting crops may change and the timing of critical activities, such as planting or harvesting, can be delayed. Medical expenses deplete savings and investment, including investment in the education of children. All these factors reduce the earning potential of individuals and households, and affect the national economy. An important component of the socioeco- nomic impact of chronic diseases is, therefore, the effect on income or earnings at the household level, and national income or gross domestic product at the national level. The cost of chronic disease can be estimated in three ways: the account- ing cost of illness method; economic growth models, which estimate the impact of chronic diseases on national income through variables such as labour supply and savings; and the full-income method, which attempts to measure the welfare losses associated with ill-health in money terms. The majority of published studies on the costs of chronic diseases have employed the accounting cost method. Estimates from all methods vary in degree of completeness and are subject to a wide range of interpreta- tions. Estimates from the economic growth approach give the lowest estimates, the full-income approach gives the highest estimates, while cost of illness estimates fall between the two. A summary of the meth- ods used in this chapter is given in Annex 4 (a more detailed description is available at http://www. Estimates vary by country, by year and for the same year in any country, reﬂecting differences in the level of health-care access and delivery, the ﬁnancing systems of the countries, and methodological variations (43–49). Heart disease alone cost 6% of National Health Service revenue at 1994–95 prices (48). In Australia, stroke is estimated to be responsible for about 2% of the country’s total attributable direct health-care costs (50–52). Some studies have highlighted effects of the burden of obesity from other perspectives, for example on health insurance plans, as well as the impact of obesity on future disease risks and associated medical care costs. The direct health expenditures attributable to physical inactivity have been estimated at approximately 2. In 1999, the World Bank estimated that tobacco-related health care accounts for between 6% and 15% of all annual health-care costs (55, 56) and between 0.
It is important to realize however treatment for dogs with gingivitis discount zyvox online american express, that this aggregate analysis does not suggest that dietary protein quality is of no importance in adult protein nutrition infection from pedicure order zyvox 600 mg with visa. The examined and aggregated studies included an analysis of those that were designed to compare good quality soy protein (Istfan et al xithrone antibiotic generic 600 mg zyvox with mastercard. The results of these studies showed clearly that the quality of well-processed soy proteins was equivalent to animal protein in the adults evaluated (which would be predicted from the amino acid reference pattern in Table 10-26), while wheat proteins were used with significantly lower efficiency than the animal protein (beef) (again this would be predicted from the procedure above). Thus, the aggregate analyses of all available studies analyzed by Rand and coworkers (2003) obscured these results and illustrate the conservative nature of their meta-analysis of the primary nitrogen balance. Moreover, this discussion and presentation of data in Table 10-27 underscores the fact that while lysine is likely to be the most limiting of the indispensable amino acids in diets based predominantly on cereal proteins, the risk of a lysine inadequacy is essentially removed by inclusion of relatively modest amounts of animal or other vegetable proteins, such as those from legumes and oilseeds, or through lysine fortification of cereal flour. Food Sources Protein from animal sources such as meat, poultry, fish, eggs, milk, cheese, and yogurt provide all nine indispensable amino acids, and for this reason are referred to as “complete proteins. The protein content of 1 cup of yogurt is approximately 8 g, 1 cup of milk is 8 g, and 1 egg or 1 ounce of cheese contains about 6 g. In the United States, the median dietary intake of protein by adult men dur- ing 1994–1996 and 1998 ranged from 71 to 101 g/d for various age groups (Appendix Table E-16). For both men and women, protein provided approximately 15 per- cent of total calories (Appendix Table E-17). Similarly, in Canada, protein provided approximately 15 percent of total calories for adults (Appendix Table F-5). The median dietary intake of threonine by adult men during 1988–1994 ranged from 2. The median dietary intake of tryptophan by adult men and women during 1988–1994 ranged from 0. As intake is increased, the concentrations of free amino acids and urea in the blood increase postprandially. These changes are part of the normal regu- lation of the amino acids and nitrogen and represent no hazards per se, at least within the range of intakes normally consumed by apparently healthy individuals. Nonetheless, a number of adverse effects have been reported, especially at the very high intakes that might be achieved with supplement use, but also at more modest levels. In addition, some naturally occurring proteins are allergenic to certain sensitive individuals; for example, the glycoprotein fractions of foods have been implicated in allergic responses. However, relatively few protein foods cause most allergic reactions: milk, eggs, peanuts, and soy in children; and fish, shellfish, peanuts, and tree nuts in adults. Even when meat is the dominant food, diets of a wide range of populations do not usually contain more than about 40 percent of energy as protein (Speth, 1989). Indeed, Eskimos, when eating only meat, maintain a protein intake below 50 percent of energy by eating fat; protein intake estimated from data collected in 1855 was estimated to be about 44 percent (Krogh and Krogh, 1913). Two arctic explorers, Stefansson and Andersen, ate only meat for a whole year while living in New York City (Lieb, 1929; McClellan and Du Bois, 1930; McClellan et al. For most of the period, the diet contained 15 to 25 percent of energy as protein, with fat (75 to 85 percent) and carbohydrate (1 to 2 percent) providing the rest, and no ill effects were observed (McClellan and Du Bois, 1930). However, consumption of greater portions of lean meat (45 percent of calories from protein) by one of the two explorers led rapidly to the development of weakness, nausea, and diarrhea, which was resolved when the dietary protein content was reduced to 20 to 25 percent of calories (McClellan and Du Bois, 1930). If continued, a diet too high in protein results in death after several weeks, a condition known as “rabbit starvation” by early American explorers, as rabbit meat contains very little fat (Speth and Spielmann, 1983; Stefansson, 1944a). Similar symptoms of eating only lean meat were described by Lewis and Clark (McGilvery, 1983).
