Overview
There is no established classification system for typhoid fever. However, typhoid fever may be classified based on duration of illness, serologic type causing disease, severity of illness and virulence factors.[1]
Classification
There is no established classification system for typhoid fever. However, typhoid fever may be classified as follows.[1]
Duration of illness
Acute disease
- Sudden in onset
- Severe by nature
- Lasts < 12 months
- Mostly symptomatic
Chronic disease
Serological type
Salmonella enterica serotype typhi
- causes classic typhoid fever syndrome
other serotypes
- causes typhoid fever like syndrome
- Salmonella paratyphi A
- Salmonella paratyphi B
- Salmonella paratyphi C
- Salmonella choleraesuis
Severity of illness
Mild disease
- Early diagnosis and treatment
- Antibiotic susceptibility
- Absence of complications
Moderate to severe disease
- Late presentation
- Presence of complications
- Antibiotic resistance
Virulence factors
High virulence factors
Low virulence factors
