In an Emergency
If you believe that you have been exposed to a biological, chemical or radiological agent, or if you believe an intentional threat will occur or is occurring, please contact local emergency responders by calling 911. If you live in an area without 911 service, contact your local emergency, medical, or police service.
You may also want to report the situation to your local or state health department. For information about how to contact your state or local health department, go to State and Local Health Departments. If you'd also like to contact CDC, you may do so in the following ways:
