Duration- 45 minutes 11/03/2024 Malaria case management for Health Care Workers 4
Introductory activity Case: A 34 years old male patient from a malarious area presented to a rural OPD with fever of three days duration. The axillary temperature record was 38 c. Based on your experience what important other questions do you ask, what tests will you order? 11/03/2024 Malaria case management for Health Care Workers 5
Definition of uncomplicated Malaria Definition : 1-Symptomatic malaria ( Fever and other associated symptoms) + 2-The presence of asexual forms of malaria parasites in blood sample + 3-No signs of severity or evidence of vital organ dysfunction. Clinical features of uncomplicated malaria are very non-specific and are shared by a number of different illnesses. Diagnosis at all times should be confirmed either by microscopy or Rapid Diagnostic Tests (RDT). 11/03/2024 Malaria case management for Health Care Workers 6
Diagnosis of uncomplicated malaria Clinical suspect: In malarious areas: A patient with fever or history of fever with in the past 48 hours is assumed to have clinical malaria. In non malarious areas: A patient with fever or history of fever within the past 48 hrs. and history of travel to malarious area within the last one month and other common causes of acute febrile illness should be also looked for. Treatment based on clinical diagnosis alone is unreliable, and when possible should be confirmed by laboratory tests. 11/03/2024 Malaria case management for Health Care Workers 7
Diagnosis of uncomplicated malaria Parasitological diagnosis: The two main methods of parasitological confirmation are light microscopy and malaria RDTs. Required for confirmation of the diagnosis of malaria. Recommended for all suspected cases in all transmission settings. Patients who test negative by malaria RDT or microscopy do not need anti-malarial medications. 11/03/2024 Malaria case management for Health Care Workers 8
Advantages of parasitological diagnosis: Improve care of parasite-positive patients. Identification of parasite-negative patients for whom another diagnosis must be sought; Prevent the unnecessary use of anti malarial drugs. Used to confirm treatment failure Improve malaria case detection & reporting. 11/03/2024 Malaria case management for Health Care Workers 9
Objective of treatment of uncomplicated malaria Three main objectives: 1-Clinical Objective : Eradication from the body of the infection that caused the illness (Cure). Prevent progression to severe disease and prevent additional morbidity associated with treatment failure. 2-Public Health Objective: Reduce transmission of the infection to others, i.e. to reduce the infectious reservoir. 11/03/2024 Malaria case management for Health Care Workers 10
Objective of treatment Contd…. 3-Antimalarial Drug Resistance Objective: Prevent the emergence and spread of resistance to antimalarial. Tolerability, the adverse effect profile and the speed of therapeutic response are also important considerations. 11/03/2024 Malaria case management for Health Care Workers 11
Practice exercise Instruction Read and analyze the case below individually and answer the given question in 10minutes Scenario- A 34 years old male patient from a malarious area presented to a rural OPD with fever, headache, chills and rigors of three days duration.
