As a health care provider, you are the eyes and ears of Public Health. Reporting notifiable conditions makes it possible for us to detect outbreaks, prevent secondary transmission, and conduct disease surveillance. For some diseases, timely reporting can help prevent illness and death.

Yes. HIPAA allows health care providers, health care facilities, and health plans to disclose protected health information to public health authorities for the purpose of preventing or controlling disease, injury, or disability [45 CFR § 164.512(b)]. Patient consent is not required.

More information on HIPAA and notifiable conditions reporting is available from the Centers for Disease Control and Prevention (CDC).

More information, report forms, and mailing addresses.

No. Notifiable conditions also include "unexplained critical illness or death," "rare diseases of public health significance" (such as a case of Cryptococcus gattii infection) and disease clusters of suspected foodborne or waterborne origin (for example, a single sporadic case of gastroenteritis due to norovirus is not reportable, but a cluster of ill children with vomiting and diarrhea after returning from camp would be).

Not necessarily. Immediately notifiable conditions (for example, tuberculosis, measles, hepatitis A, pertussis, meningococcal disease, and suspected bioterrorism agents), should be reported as soon as they are clinically suspected, preferably while you are still with the patient. These are listed in bold. "If in Doubt, Report it Out."

Provide the patient's notifiable condition, demographic and contact information, your name and phone number, relevant clinical and laboratory data (such as liver transaminases for patients with hepatitis), risk factors/suspect exposure sources (e.g., a history of injection drug use for hepatitis B or C), travel history, information on ill family members or other contacts, and whether the patient is in a sensitive occupation (such as a restaurant worker or child care provider with E. coli O157:H7). Please indicate if the patient is aware of the diagnosis, as we prefer to do interviews after the patient is informed.

Report cases of tuberculosis, sexually transmitted diseases, and HIV/AIDS to their respective programs in Public Health. For all other conditions, contact the Communicable Disease Epidemiology and Immunization Section at 206-296-4774. See item #3 above for contact information, or refer to our website or the notifiable condition pocket card.

Yes. Don't assume that a laboratory has reported a condition. Laboratories don't report suspected cases, clinically diagnosed cases, or clusters of illness that are not laboratory-confirmed.

Yes. Unless you know that a case of a notifiable condition has already been reported, you are legally required to report it to Public Health.
