Understanding care
Clinical care may include exposure-based testing and specialist assessment of infection and organ involvement. A qualified clinician decides which investigations and options fit the individual situation.
When to seek help
Seek clinical advice for persistent fever, worsening illness or relevant exposure. Confusion, stiff neck, severe breathlessness or collapse requires urgent emergency assessment.
For severe breathing difficulty, collapse, suspected stroke, or another emergency, call local emergency services immediately. In India, call 112.
