  1. A 3 year old month old child is taken to your GP surgery in the late evening. Her father reports that she has had a temperature since yesterday. Over the last few hours she has complained of headache and has become very lethargic. An hour ago he noticed a rash around her ankles.

a) What clinical diagnosis do you consider most urgently? (5) b) What characteristic of the rash would support this diagnosis? (5) c) What is the full species name of the organism most likely to be associated and what are the subtypes/subclassification of this species (10). d) What is the most urgent action required given your suspected diagnosis? (15) e) Are any special precautions required in relation to risk of transmission of infection to you or your clinical colleagues (5) f) During the day the child normally attends a crèche where there are 50 other children. What, if any, are the risks of transmission of the suspected organism to other children in the crèche (5). g) Estimate the likely number of children in the crèche you would expect to develop a similar clinical syndrome in the two weeks after this presentation if no specific measures are taken (5). h) What is your most specific and important obligation in relation to prevention of risk of transmission of this infection in the community? (5) i) List the laboratory investigations that would assist in confirming the suspected diagnosis when the child reaches hospital (NOTE This is not limited to the microbiology laboratory investigations). (5) j)Describe precisely the specimens that should be submitted for each laboratory investigation and describe any specific precautions necessary in respect of specimen collection. (5) k) Describe in detail how the microbiology laboratory will process each specimen that you submit. (15) l) Describe the results you would expect to see if your suspected diagnosis is correct. (10) m) Briefly outline the measures that are available to reduce the frequency of occurrence of this type of infection in the general community (10)
