When to get help

These are general warning signs, not advice about any particular condition. If you are not sure, err upward — it is always reasonable to be checked.

    • is unconscious, or cannot be woken

Warning signs for a particular condition

Go through one condition’s warning signs, one question at a time.

If you are not sure

Trust the change rather than the number. Someone who is behaving unusually — confused, unable to speak in full sentences, unable to stay awake, or simply not themselves — needs to be seen, whatever their temperature or blood pressure reads.

Nothing on this page replaces a clinician who can examine the person in front of them. Read the full disclaimer.

For poisoning, a mental health crisis, or a safety concern, see who to call.

Who to call

Life-threatening emergency

  • Emergency services

    Anyone struggling to breathe, with chest pain, unresponsive, bleeding heavily, or having a stroke or a seizure that will not stop.

  • Poison Help

    Any swallowed, inhaled, splashed or injected substance — medicines, cleaning products, plants, carbon monoxide, a child who has eaten something. Free, confidential, 24 hours, interpretation in 161 languages.

    This is one national number. It routes your call to the poison centre that covers where you are calling from, so there is no separate number to look up for your state.

Mental health and crisis

Safety

Reporting an infectious disease

Reporting a notifiable disease — rabies exposure, HIV, tuberculosis, measles, and about 120 others — is a legal duty of the diagnosing clinician or laboratory, not of the patient. Reports go to your state or local health department, and the state reports onward to CDC. Which diseases are reportable is set by state law, so the list is not the same everywhere.

If you are a patient or a carer

You do not need to report anything. Tell the clinician treating you what you were exposed to and when — they make the report. For a possible rabies exposure, an animal bite or scratch or a bat in the room, wash the wound with soap and running water for 15 minutes and seek care the same day; your health department decides whether you need the vaccine and arranges it.

If you are a clinician or a laboratory

Report to your state or local health department, not to CDC — states hold the reporting law and pass cases upward. Timeframes vary from immediately by telephone for the most serious to within a few days for the rest.

Suspected high-consequence pathogen

Smallpox, a viral haemorrhagic fever, anthrax or another agent needing an immediate national response: telephone your state health department and CDC at the same time. The CDC Emergency Operations Center answers around the clock and will put you through to the relevant specialist.

General questions

For questions about a disease, a vaccine or travel that are not urgent and not a report.

Things your state health department handles

Some things are decided where you live rather than nationally. Your state or local health department is the right call for these.

  • Rabies exposure — an animal bite or scratch, or a bat in the room. Wash the wound with soap and water for 15 minutes and seek medical care the same day; your health department advises on whether you need the vaccine and where to get it.
  • Reporting an infectious disease, or asking whether you need to be tested after an exposure
  • Getting a copy of your own or your child's immunisation record
  • Local outbreak information, water quality and food safety
Find your state health department
