Lumbar puncture(2) Complete Blood Count

(3) Lumbar punctureto obtain spinal fluid sample for CSF cultureFetal positionA spinal needle is inserted between the lumbar vertebraeL3/L4 or L4/L5

(4) Skin biopsy and gram stainA skin biopsy is a procedure in which a sample of skin tissue is removed, processed, and examined under a microscope.

(Bactrim, Septra)

VII. Prevention and Control(1) Respiratory isolation of patients for the

first 24 hours(2) Vaccination

Although a vaccine is available for meningococcus, it is still difficult to produce a vaccine for the type B organism
