Study Notes
Malaria Overview
- Caused by Plasmodium species, including P. knowlesi.
- Infection involves sporozoites, which are the infected stage.
- Characterized by two main stages: erythrocytic and exo-erythrocytic.
Pathogenesis and Stages
- Malaria progresses through various stages in the human body.
- Development of schizonts occurs in both erythrocytes and liver cells.
Diagnosis
- Confirm diagnosis via microscopic examination of blood samples.
- Utilize Rapid Diagnostic Tests (RDT) for antigen detection.
- Molecular detection methods such as PCR enhance diagnostic accuracy.
- Conduct hematological tests (CBC) and biochemical tests (RBS, RFT, LFT).
Treatment
- Treatment for mild to moderate malaria includes Artemisinin-based combination therapies (ACTs).
- Common regimen includes Artemether + lumefantrine.
- Severe cases may require hospitalization and IV Artesunate or Quinine infusion.
Prevention Strategies
- Vector control is crucial in preventing malaria transmission.
- Implement indoor residual spraying to reduce mosquito populations.
- Employ long-lasting insecticide nets (LLINs) and mosquito nets for sleeping.
Measles Overview
- Caused by the Morbilli virus, highly contagious and airborne.
- Transmission occurs through person-to-person contact, particularly via respiratory droplets.
Incubation Period
- Symptoms appear 7-18 days post-exposure to an infected person.
- Majority of symptoms develop around 10 days after exposure.
Clinical Features and Complications (Measles)
- Initial symptoms may resemble respiratory infections.
- Complications may include severe respiratory issues, leading to potential hospitalization.
- A chest X-ray can aid in diagnosis to identify pulmonary involvement.
