These infections may affect the brain, spinal cord, or eyes, presenting with symptoms such as fever, headache, neck stiffness, vision changes, or confusion. Early and accurate identification of the causative agents is critical for effective treatment. Rapid diagnostic tests play a key role in ensuring timely detection and guiding appropriate medical intervention.
