The provision of more favourable habitat at a distance from an outbreak/contaminated area may encourage animals away from those areas and thus reduce risks of further disease spread buy line losartan diabetes with renal manifestations. Habitats can be modified to prevent large host die-offs 25 mg losartan mastercard metabolic basis of inherited disease 1989, whose carcases could become substrates for the growth of disease-causing agents generic losartan 25mg amex diabetes education handouts. For example, raising water levels in warm, dry weather may prevent the death of bacteria-harbouring fish and aquatic invertebrates. Under these circumstances compensatory habitat restoration should, wherever possible, be undertaken. This may involve habitat restoration, creation or enhancement with the aim of compensating for lost habitat. Managing wetlands: frameworks for managing Wetlands of International Importance and other wetland sites. Chapter 4, Field manual of wildlife diseases: general field procedures and diseases of birds. Revue scientifique et technique (International Office of Epizootics), 21, (1): 159-178. Restrictions on the movements of domestic animals and people, usually imposed by government authorities, can therefore be an effective tool for preventing and controlling disease transmission by reducing contact between infected and susceptible animals. Such measures are particularly useful in wetland sites with substantial human activity, such as human residencies, intensive livestock production, large numbers of visitors or hunters, captive breeding and/or translocation programmes. Movement restrictions to prevent an outbreak Preventative measures may be taken as a response to periods of elevated risk of an outbreak affecting a wetland. In the event of a disease outbreak near to a wetland or at a national level, implementation of animal movement restrictions may be considered a prudent measure. Where a disease outbreak is considered serious, national stock ‘standstills’ may be imposed which restrict all animal movement. It is also important to note that movements of people may also be restricted to and from a wetland. Trade in animals and derived products may also be prohibited locally, nationally or internationally. Movement restrictions to control an outbreak Rapid notification of the presence of disease by wetland managers is vital for the timely mobilisation of control activities. The overall cost of a disease management strategy may be reduced if disease is prevented or controlled at an early stage during the outbreak, and economic impacts related to restricted animal trade will be minimised. If a notifiable disease is confirmed in domestic animals and/or wildlife at a wetland site, there are likely to be automatic movement restrictions placed on people and animals by government authorities to reduce the risk of further spread. During such an outbreak stock must not be moved within or external to the site until restrictions are lifted: contravention of statutory movement restrictions can result in criminal prosecution. The site contingency plan should be implemented and personnel guided through the process in the event of a disease outbreak [►Section 3. Controls may be implemented whereby movements of susceptible species are only permitted under strict, designated conditions, when it is deemed safe. When such activities are allowed to resume, they should be subject to surveillance and rigidly enforced codes of practice. If area restrictions have been imposed on a site, visits to other wetland sites or areas with livestock should only take place if they are essential and should be subject to strict biosecurity measures [►Section 3. Until a disease outbreak is brought under control, rights of way through the infected area should be closed and non-essential visits to infected sites should be suspended. Infected or potentially infected sites, animals and their products, personnel, potentially contaminated animal products and other materials may be placed under quarantine. Appropriate health restrictions can be placed on the movement of susceptible animals into, or out of, the quarantine area until the infection is considered to have been removed. This may be supported by disinfection and decontamination of personnel, vehicles, equipment and other materials leaving and entering the quarantine area [►Section 3. Quarantine guidelines vary depending on the case and factors involved (disease, terrain, local human and animal populations) but will generally cover at least a 3-5 km radius from the initial case. Movement restrictions are often imposed over a wider area around the quarantined or infected site as part of a zoning strategy which seeks to identify disease infected, disease-free and buffer zone areas [►Section 3. The coverage of the outbreak area and surrounding areas of risk can be determined from surveillance activities and relies on an understanding of the epidemiology of the disease and host ecology [►Section 3. Animal movement within identified zones is not permitted unless appropriate permits have been issued by the local authorities.
If exposure to the toxin via an aerosol is suspected buy losartan with american express diabete yahoo, remove any clothing and store in plastic bags until it can be washed with soap and water cheap losartan express blood glucose tracking log. Severe cases require supportive treatment generic losartan 50mg fast delivery diabetes mellitus hyperglycemia, especially mechanical ventilation, which may be required for weeks or months. The disease can result in negative perception and therefore unnecessary destruction of wildlife. Avian botulism is probably one of the most important diseases of migratory waterbirds worldwide, and without intervention, great numbers of birds can die over a short period of time. Relatively uncommon in domestic mammals although up to 65% of affected cattle herds may fall ill and up to 40% of affected chicken flocks may die. Livestock mortality associated with dead poultry and poultry waste can be a relatively frequent occurrence. The death rate is high if left untreated but vastly decreases with supportive care. Economic importance There is potential for economic losses to the livestock industry, due to illness and death of infected animals, with cattle and poultry particularly affected, and likely trade restrictions imposed during and after an outbreak. Illness in humans can result in significant economic losses due to the time lost from normal activities. In: Field manual of wildlife websites diseases: general field procedures and diseases of birds. A highly infectious bacterial disease which can lead to mass mortality of birds, particularly waterfowl. Death occurs quickly after infection (in less than 24 hours) and the disease can spread rapidly through a wetland killing thousands of birds in a single outbreak. Mass mortality of poultry can cause significant economic impacts on the poultry industry. Outbreaks occur at all times of the year, but major mortality events are usually observed when waterfowl are concentrated in wintering areas or during spring migration. The disease often affects the same wetlands and bird populations each year and outbreaks tend to follow the migration routes of some birds. Species affected Domestic fowl and almost any species of bird can be infected: most commonly ducks, geese, swans, coots, shorebirds, gulls, and crows. The bacterium can also cause infections in domestic cattle, pigs, rabbits, cats and dogs. Geographic distribution Frequent reports of affected waterfowl in North America but also occurs in South America, Antarctica, Africa, Europe, Asia and Australia. Environment Occurs in a range of habitats including freshwater wetlands, brackish marshes, and saltwater environments which support birds. How is the disease Direct contact with infected birds, contact with secretions or faeces of infected transmitted to animals? Transmission may also occur through the inhalation of airborne water droplets when birds take flight and possibly through mechanical transfer by biting arthropods that feed on birds after having fed upon contaminated carcases or contaminated environments. Bacteria are released into the environment by dead and dying birds, by live birds carrying the disease or from contaminated objects (e. How does the disease Dense concentrations of waterfowl can enhance disease spread through bird to spread between groups bird transmission in the ways described above. How is the disease Most human infections result from an animal bite or scratch, mainly from transmitted to humans? Infections can also arise through inhalation of bacteria which is most likely to happen in confined areas of air movement where a large amount of infected material is present (e. Birds often die quickly before showing any clinical signs of illness although the number of sick birds increases when a die-off is prolonged over several weeks. Other signs include: Convulsions, swimming in circles, throwing the head back between the wings, erratic flight, mucous discharge from the mouth, soiling or matting of the feathers around the vent, eyes, and bill, nasal discharge and fawn- coloured, yellow or blood-stained droppings. Chronic conditions can occur with birds exhibiting depression, diarrhoea and anorexia. Recommended action if Contact and seek assistance from animal and human health professionals suspected immediately if there is illness in birds and/or people. Diagnosis Isolation of the causative agent by health professionals is needed for a definitive diagnosis. When this is not possible, heart blood, liver tissue and bone marrow should be collected in a sterile manner.

Health and safety risks of using chemicals Disinfectants may be toxic to humans as well as animals and plants, and therefore all chemicals should be used in accordance with the relevant safety precautions. Key factors that help to assess the human health risk of chemical exposure include the duration, intensity (i. Wetland managers may be responsible for informing workers about the chemical hazards involved and implementing disinfection control measures. Where required, wetland managers should be able to readily provide workers with appropriate personal protective equipment and Material Safety Data Sheets (usually available on the internet) for each chemical or mixture of chemicals that may be in use. Chapter 4, Field manual of wildlife diseases: general field procedures and diseases of birds. Animal health authorities should be contacted to advise on appropriate measures remembering that the health and safety of the personnel involved in any disposal operation are paramount. Rapid and effectively planned carcase collection and disposal is essential to prevent spread of infectious disease and to reduce potential secondary poisoning in the case of toxic diseases. Presented below is a broad overview of the most commonly used methods for animal carcase collection and disposal, each has strengths and weaknesses which should be considered in the context of each specific situation. Collection of carcases Ideally carcases can be dealt with in situ to reduce chances of spread of infectious agents. However, in most circumstances where an outbreak has occurred and there are a number of carcases, they will need to be gathered to a central location for disposal. To help prevent potentially contaminated body fluids leaking during collection and transport to the central location, wherever possible (depending on size of dead animal), the carcases should be double bagged in plastic leak-proof bags (noting that claws, beaks etc. Wooden containers are difficult to decontaminate as fluids soak into wood so, wherever possible, plastic or metal bins/barrows etc. If carcases are being transported off-site to disposal facilities this must be done in leak-proof vehicles. Advice should be sought from animal health authorities regarding transportation of potentially infectious carcasses. Burial of carcases This is the often a preferred method of disposal as it is relatively easy to organise, quick, inexpensive, has potentially fewer immediate environmental hazards and it is a convenient means of disposing of large numbers of carcases. However, the suitability of this method needs to be considered carefully in or around wetlands as pits must not contaminate ground water nor be susceptible to inundation. Also care must be taken to avoid later exposure of carcases to people or other animals. Open pits were historically used for this purpose but potential problems include exposure to scavengers and the threat to groundwater quality. If carcases do not decompose sufficiently then contaminants may leach from the pit. Closed pits are now generally favoured with at least a metre of topsoil laid over carcases. This restricts the carcases rising in the pit due to gas entrapment, helps prevents access to scavengers, absorbs decomposition fluids and facilitates odour filtration. Potential scavengers can be further dissuaded by the addition of lime or fuel oil to the carcases, or use of thorny plants such as acacia spread across the pit. Factors to consider include: height of water table distance from watercourses or wells access to site facilities available equipment required safety to personnel acceptability to landowner protection from public view distance from residences/roads surface slope cultural/historical considerations biosecurity considerations. Incineration (burning) of carcases Incineration of carcases is advantageous due to the generally pathogen-free solid waste by- product. However, factors to consider prior to burning carcases include: location of site prevailing wind direction access to site type of animal carcase involved fuel availability number of carcases to burn environmental considerations. Common methods of incineration include open air burning, fixed facility incineration and air curtain incineration. To achieve the high temperatures required to completely consume carcases in open air burning additional combustible materials (e. Carcases can be either put on a platform above a fire at ground level or within a pit.

Nuclear medicine is a medical specialty that is used to diagnose and treat diseases in a safe and painless way. Nuclear medicine procedures permit the determination of medical information that may otherwise be unavailable, require surgery, or necessitate more expensive and invasive diagnostic tests. The procedures often identify abnormalities very early in the progression of a disease — long before some medical problems are apparent with other diagnostic tests. This early detection allows a disease to be treated sooner in its course when a more successful prognosis may be possible. Nuclear medicine refers to medicine (a pharmaceutical) that is attached to a small quantity of radioactive material (a radioisotope). There are many different radiopharmaceuticals available to study different parts of the body. Which radiopharmaceutical is used will depend upon the condition to be diagnosed or treated. Radiopharmaceuticals are introduced into the patient’s body by injection, swallowing, or inhalation. The pharmaceutical part of the radiopharmaceutical is designed to go to a specifc place in the body where there could be disease or an abnormality. The radioactive part of the radiopharmaceutical that emits radiation, known as gamma rays (similar to x-rays), is then detected using a special camera called a gamma camera. This type of camera allows the nuclear medicine physician to see what is happening inside your body. During this imaging procedure, the patient is asked to lie down on a bed and then the gamma camera is placed a few inches over the patient’s body. These images allow expert nuclear medicine physicians to diagnose the patient’s disease. Depending upon the kind of pictures that need to be taken, these cameras will operate in a stationary mode, move across the body or rotate around the body. Gamma cameras do not hurt, nor do they make any noise that might frighten patients. Before they are used, they are tested carefully and are approved for use by Not at all.
