ential Diagnosis

Meningitis or Meningococcal

septicaemia

Toxic Shock Syndrome

Rocky Mountain Spotted Fever

Claa

Signs and Symptoms of Meningococcal

Meningitis with shock

Headache(common)

Neck/back stiffness

High fever

Diffuse erythematous rash

Rocky Mountain Spotted Fever

Tick-borne disease caused by the organismRickettsia rickettsii

Rickettsiae are transmitted from tick to

human during feeding and the organismspreads through the body via both bloodand the lymphatic system.

The incubation phase of infection rangesfrom 3-12 days, depending on the volumeof the inoculum



MFFFrom all this we came up with diagnosis of Invasive Meningococcal

Disease



Septic Shock

Bacterial Causes:

N.meningitidis

S.pneumoniaH.Influenza

L.monocytogenes

But only N. meningitidis can cause

meningococcal septicaemia

(which we think is the most likelycause btw)
