Answers to questions on the spread and control of diseases

Answers to questions on the spread and control of diseases List and discuss briefly major public health strategies for communicable disease control. Choose five communicable diseases and discuss what public health strategies will be appropriate in each case. Major Public Health Strategies for Communicable Disease Control The main public health strategies to control communicable diseases include all measures designed to prevent or reduce the incidence, prevalence and consequences of disease (WHO 1984). These measures are included in primary health care and involve participation of community, support from different government, public and private sectors and coordination between these sectors (WHO 1978). The control measures are directed against reservoir or sounce of infection, the root of transmission and susceptible host ( people at risk). i) Controlling Reservoir of Infection. It includes early diagnosis or detection of cases or carriers, notification of disease, isolation, treatment and quarantine. ii) Interrupting Transmission of Disease . This is done by interrupting direct transmission and indirect transmission of infective agent from patient and carrier to susceptible host by changing some part of man’s environment. The public health strategies to achieve this includes clean water supply, improving sanitation, proper cooking and refrigeration, improving personal hygiene, controlling vectors and proper handling of secretions and excretions of humans and animals. iii) Protection of Susceptible Host or Patient at Risk This includes active immunization, passive immunization, combination of active and passive immunization and prophylaxis by drugs. iv) Other measures that have interrupted transmission of many diseases in developed countries include legislation for integrated and effective public health programs, improved quality of life and better education. Surveillance follows control measures. Five Communicable Diseases and Public Health Strategies to Control them 1-Chickenpox is acute highly infectious disea se caused by varicella zooster virus (VZV) usually in children. It spreads by airborne particles and direct contact. The control strategies are notification, isolation of cases for six days after the rash appears, disinfection of articles soiled with secretion from nose, mouth and skin and using gloves and face mask while attending patient. Antiviral drugs are effective if used in first 24 hours of appearance of skin rash. Human varicella zoster immunoglobulin is given to contacts and immunocompromrised. A live attenuated vaccine is available and used in US and some other countries for children at one year of age. 2-Measles is acute highly infectious disease of childhood caused by a myxovirus. The control strategies include routine vaccine coverage of all children at 9 months and 4 years of age using live attenuated vaccine. Catch up vaccination is done for children who miss out. Successive generations of children are vaccinated. Isolation in initial stages of incubation period and disinfection of articles can help control spread. Notification to local health authorities, epidemiological investigation and health education are also necessary. 3-Diphtheria is caused by corynebacterium diphtheriae and affects upper respiratory tract. Control includes early detection of cases and carriers, notification, isolation in the hospital, and treatment of cases by diphtheria anti-toxin and carriers by erythromycin. Contacts are given booster dose of anti-toxin if they have not received in last two years and surveillance of close contacts is done for several weeks after exposure. On community bases the effective control is achieved by active immunization of diphtheria vaccine at age of six weeks, ten weeks, fourteen weeks, and booster doses sixteen to twenty-four months and five years.

See attach - Essay Example According to the play paragraph presented, the relation between the speaker and other people has been affected by his mentality or perception towards them. He sees other people as advantaged having compared his daily occurrences to theirs. According to his perception, his life occurrences are the worst compared to any other person. All these can be proven by the utterances in the last four sentences of the given play paragraph. The speaker in the last paragraph of the play admits that he cannot meet his full objective based on his personality and set to fake and try a new pattern. As per my perception, the speaker is very intelligent and trusts his personality. This can be proven by his words in the first three sentences that he is determined to prove villain since he cannot prove a lover in the fair well-spoken days (Wells, 32). The speaker is a hard working and determined person. His change of pattern shows that he is a character that can go to extreme to achieve his desire. This can be explained by his utterance in the seventh sentence of the given paragraph. In this sentence, the speaker plots to set his brother Clarence and the king in a deadly hate to prove villain (Wells, 32). Comparing the two lines of the play paragraphs, the speaker failed in accomplishing his life desire in the right path as those who chose the villain path succeed. This has brought a change in the speaker’s perception about his personality that he is set to abandon his personality achieve his desire. The soul reason is to prove villain and drive people back to reality. As per my perception, induction is always the best mode of logical thought though surrounded by minor setbacks (Wells, 34). Induction is a slow process that is based on reality while deduction is based on presumption that tends to drive people to the shortest way possible to achieve their life desire. According to the first paragraph, the

Climate Change and The Global Warming Debate Case Study

Climate Change and The Global Warming Debate - Case Study Example Perhaps the most illustrative and influential in getting the message across was Al Gore’s ‘An Inconvenient Truth.’ The title in itself denotes of the apprehension to identify global warming as an imperative issue that must be discussed in order to address what is necessarily happening in the world. The documentary showed among other things how the polar ice caps are swiftly melting to the effect that a huge amount of the sun’s heat is absorbed and trapped in our atmosphere causing an increase in the earth’s temperature. These glaciers play an important role and have a direct correlation to global warming. The film supports this with scientific data and research accompanied by actual pictures of places in between decades showing the discrepancy man have caused (Guggenheim & Gore, 2006). Faced with this global problem, scientists have also offered solutions to impede and slowdown the process. The most important tool in dealing with environmental woes i s the shift toward sustainability for purposes that human beings do not exhaust the Earth’s natural resources. ... Reliance on energy is a given fact and where our main sources of energy such as coal and fossil fuel are mainly consumable, they necessarily run out that those who are rich in them rake in the profit and play a major role in the determination of the world’s economy. Renewable energy comes in as an answer to this dilemma as a viable alternative source of energy. The Intergovernmental Panel on Climate Change on their 2007 Synthesis Report provides for the necessity and the benefits of renewable energy. The introduction of new policies that implement energy efficiency should entail the institution of renewable energy which also promotes economic benefits and sufficient energy accompanied by lesser pollution. Among the main thrust of the report is to identify how this should also be beneficial for developing countries who require more energy not only in the business establishments but also particularly in the household. These countries rely mostly on coal as a source of energy and often resort to deforestation. The IPCC provides that â€Å"Energy efficiency and utilisation of renewable energy offer synergies with sustainable development† (p. 59, 2007). This in consequence provides for economic benefits for countries requiring cost-efficient energy with security while reducing pollution. The main opposition to the proposition that there truly is global warming brought about mainly by the copious amount of greenhouse gasses are ubiquitously called greenhouse doubters. The advocates to bring global warming into the limelight on the other hand are most likely to call them as deniers. They have been more prominent in the 1980s through to early 2000 when there had been more scientists in consensus that global warming is a reality based on scientific data.
