Recommended action if Contact and seek assistance from animal and human health professionals suspected immediately if there is any illness in livestock and/or people buy suprax 200mg fast delivery. For dead animals quality suprax 100 mg, whole blood order suprax 200 mg without a prescription, liver cheap 100mg suprax, lymph nodes and spleen are preferable tissues for detecting the virus cheap 100mg suprax overnight delivery. Construct artificial homes or manage for mosquito predators such as bird, bat and fish species. Reduce mosquito breeding habitat: Reduce the number of isolated, stagnant, shallow (2-3 inches deep) areas. Install fences to keep livestock from entering the wetland to reduce nutrient loading and sedimentation problems. In ornamental/more managed ponds: Add a waterfall, or install an aerating pump, to keep water moving and reduce mosquito larvae. Keep the surface of the water clear of free-floating vegetation and debris during times of peak mosquito activity. Vector control (chemical) It may be necessary to use alternative mosquito control measures if the above measures are not possible or ineffective: Use larvicides in standing water sources to target mosquitoes during their aquatic stage. This method is deemed least damaging to non- target wildlife and should be used before adulticides. However, during periods of flooding, the number and extent of breeding sites is usually too high for larvicidal measures to be feasible. The environmental impact of vector control measures should be evaluated and appropriate approvals should be granted before it is undertaken. Biosecurity Protocols for handling sick or dead wild animals and contaminated equipment can help prevent further spread of disease: Avoid contact with livestock where possible. Wear gloves whilst handling animals and wash hands with disinfectant or soap immediately after contact with each animal. Wear different clothing and footwear at each site and disinfect clothing/footwear between sites. Monitoring and surveillance Regular inspection of sentinel herds (small ruminant herds located in geographically representative areas) in high risk areas such as locations where mosquito activity is likely to be greatest (e. As a general guide, sentinel herds should be sampled twice to four times annually, with an emphasis during and immediately after rainy seasons. In livestock, clinical surveillance for abortion with laboratory confirmation and serology, and disease in humans in areas known to have had outbreaks. Restrict or ban the movement of livestock to slow the expansion of the virus from infected to uninfected areas: - Livestock should not be moved into/out of the high-risk epizootic areas during periods of greatest virus activity, unless they can be moved to an area where no potential vector species exist (such as at high altitudes). Bury animals rather than butchering them as freshly dead animals are a potential source of infection. For control of disease in captive collections of wild ruminant species, guidelines above for livestock, habitat and vector management may be applicable. Humans In the epidemic regions, thoroughly cook all animal products (blood, meat and milk) before eating them. Reduce the chance of being bitten by mosquitoes: Wear light coloured clothing which covers arms and legs. Use impregnated mosquito netting when sleeping outdoors or in an open unscreened structure. Note that some repellents cause harm to wildlife species, particularly amphibians. African buffalo and domestic buffalo are considered ‘moderately’ susceptible with mortalities of less than 10%. Camels, equids and African monkeys including baboons are all considered ‘resistant’ with infection being inapparent. Effect on livestock Pregnant livestock are most severely affected with abortion of nearly 100% of foetuses. Lambs and kids are most at risk with mortalities of 70– 100%, followed by sheep and calves (20–70%), and then adult cattle, goats and domestic buffalo (<10%). Economic importance There is potential for significant economic losses in the livestock industry due to death and abortion of infected animals and possible trade restrictions imposed during and after an outbreak.

Evidence-based medicine is the way to maximize the benefits of science in the practice of health care purchase 100 mg suprax amex. Lord Kelvin 200 mg suprax free shipping, President of the Royal Society purchase suprax 100mg visa, 1895 Learning objectives In this chapter you will learn: r cause-and-effect relationships r Koch’s principles r the concept of contributory cause r the relationship of the clinical question to the type of study The ultimate goal of medical research is to increase our knowledge about the interaction between a particular agent (cause) and the health or disease in our patient (effect) generic 100mg suprax overnight delivery. Causation is the relationship between an exposure or cause and an outcome or effect such that the exposure resulted in the outcome suprax 200 mg cheap. However, a strong association between an exposure and outcome may not be equivalent to proving a cause-and-effect relationship. By the end of this chapter, you will be able to determine the type of causation in a study. Cause-and-effect relationships Most biomedical research studies try to prove a relationship between a partic- ular cause and a specified effect. The cause may be a risk factor resulting in a disease, an exposure, a diagnostic test, or a treatment helping alleviate suffer- ing. The stronger the design of a study, the more likely it is to prove a relationship between cause and effect. Not all study designs are capable of proving a cause-and-effect relation- ship, and these study designs will be discussed in a later chapter. In some studies relating to the prognosis of disease, time is the independent variable. It can be an outcome such as death or survival, the degree of improvement on a clinical score or the detection of disease by a diagnostic test. You ought to be able to identify the cause and effect easily in the study you are evaluating if the structure of the study is of good quality. Types of causation It’s not always easy to establish a link between a disease and its suspected cause. For example, we think that hyperlipidemia (elevated levels of lipids or fats in the blood) is a cause of cardiovascular disease. Perhaps hyperlipidemia is caused by inac- tivity or a sedentary lifestyle and the lack of exercise actually causes both cardio- vascular disease and hyperlipidemia. Streptococcus viridans is a bac- terium that can cause infection of the heart valves. However, it takes more than the presence of the bacterium in the blood to cause the infection. We cannot say that the presence of the bacterium in the blood is sufficient to cause this infection. There must be other factors such as local deformity of the valve or immunocompromise that make the valve prone to infection. In a more mundane example, it has been noted that the more churches a town has, the more robberies occur. No – it simply means that a third variable, population, explains the number both of churches and of muggings. Likewise, we know that Streptococcus viridans is a cause of subacute endocarditis. But it is neither the only cause, nor does it always lead to the result of an infected heart valve. In medical science, there are two types of cause-and-effect relationships: Koch’s postulates and contributory cause. Robert Koch, a nineteenth-century microbiologist, developed his famous postulates as criteria to determine if a cer- tain microbiologic agent was the cause of an illness. Acute infectious diseases were the scourge of mankind before the mid twentieth century. As a result of bet- ter public health measures such as water treatment and sewage disposal, and antibiotics, these are less of a problem today. He created the following postulates in an attempt to determine the relationship between the agent causing the illness and the illness itself. Second, when found it must be able to be isolated from the diseased host and grown in a pure culture. Next, the agent from the culture when introduced into a healthy host must cause the illness. Finally, the infectious agent must again be recovered from the new host and grown in a pure culture. While this model may work well in the study of acute infectious diseases, most modern illnesses are chronic and degenerative in nature. Illnesses such as dia- betes, heart disease, and cancer tend to be multifactorial in their etiology and usually have multiple treatments that can alleviate the illness.
