Canefield fever: when to get help

Go through these in order and stop at the first one that applies. If you are reading this for someone else, answer for them.

  1. 1

    Is any of this happening now?

    Call 911

    Get urgent or emergency help for:

    • Trouble breathing, chest pain, or coughing up blood
    • Confusion, collapse, a seizure, or difficulty waking
    • Very little or no urine
    • Heavy or unexplained bleeding
    • A severe headache with a stiff neck or altered awareness
    • Inability to keep fluids down with signs of severe dehydration

    And for anyone, someone who:

    • has had a seizure that will not stop, or does not wake up afterwards
    Other emergency signs, for anyone
    • Someone who is struggling to breathe, gasping, choking, or cannot get words out
    • Someone who has chest pain, tightness or pressure lasting more than a few minutes
    • Someone who has sudden weakness or drooping on one side of the face or body, slurred speech, or sudden confusion
    • Someone who is unconscious, or cannot be woken
    • Someone who is bleeding heavily and it will not stop with firm pressure
    • Someone who has lips or skin that look pale, blue, grey or blotchy
    • Someone who you believe has taken an overdose or swallowed something poisonous
  2. 2

    Is any of this happening?

    Be seen today

    Seek prompt medical advice if you develop fever, headache, strong muscle pain, red eyes, vomiting, or unusual tiredness within a month of contact with floodwater, freshwater, wet soil, rodents, livestock, or animal urine.

    Explain the exposure clearly.

    Early leptospirosis can resemble many other infections.

    These signs do not prove that you have canefield fever, but they can indicate serious organ involvement or another urgent condition.

    And for anyone, someone who:

    • has a fever with a stiff neck, a rash that does not fade under pressure, or severe headache
  3. 3

    Does any of this apply?

    Book an appointment

    Arrange follow-up if symptoms are not improving, return after a brief recovery, or continue after treatment.

    You should also seek assessment for reduced urine, yellow skin or eyes, ongoing vomiting, new eye symptoms, or worsening weakness.

Every sign above is quoted from the sofidex article on Canefield fever. If you are not sure, err upward — it is always reasonable to be checked.
