What are the Limitations of Microscopy in Epidemiology?
While microscopy is a powerful tool, it has some limitations:
1. Sensitivity: Some pathogens may be present in low numbers and difficult to detect microscopically. 2. Specificity: Morphological similarities between different pathogens can sometimes lead to misidentification. 3. Skill Requirement: Accurate microscopy requires trained personnel to prepare samples and interpret results correctly. 4. Equipment: Advanced types of microscopy, such as electron microscopy, require expensive and specialized equipment.
