Diseases case studies

  1. 1. DISEASES CASE STUDIES Alana W.
  2. 2. Infectious Disease INFLUENZA
  3. 3. Cause and transmission    Influenza is caused by a virus which attacks the body’s cells The virus mutates often and new strains arise. Unfortunately immunity against one strain does not protect against other strains. Influenza virus may be transmitted among humans in three ways:  By direct contact with infected individuals  By contact with contaminated objects  By inhalation of virus-laden aerosols
  4. 4. Symptoms       High fever Severe aches and pains (often in the back and muscles) Severe headache Cough Intermittent sweating and shivering Sometimes vomiting or diarrhoea
  5. 5. Treatment For most people it is best to treat the symptoms of influenza and await natural recovery.  Take symptom relief eg. paracetamol or aspirin to help with fever and aches and pains There are now three influenza treatments licensed for use in the UK:  Amantadine, taken by mouth  Oseltamivir, taken by mouth  Zanamivir, a powder that is inhaled
  6. 6. Prevention There are many influenza viruses. Only one or two tend to reach epidemic proportions each year. By monitoring the progress of these worldwide, the World Health Organisation decide on the best mixture of influenza types to be included in that year’s vaccine. It is advised that people at high risk of infection are vaccinated yearly.
  7. 7. Incidence Influenza is more common during winter, peaking in August as shown in this map.
  8. 8. Incidence Influenza is most common in children younger than 5 and adults aged 65+, as shown in this map from Western Australia

  12. 12. Treatment     Most anorexics go into hospital when they become extremely ill. Here, the first goal of treatment is to increase and stabilise their weight. Behaviour therapy – encouraging the person to eat by giving privileges (eg. telephone calls, visits, watching TV) for eating. Keeping a diary recording food intake, activity and thoughts and feelings. This may uncover deeper emotional problems. Therapy
