What a public health alert looks like
Alerts vary by scope and severity.
Common types include:
– Health advisories: Inform the public about a potential hazard and recommended precautions.
– Boil water notices: Direct residents to boil or use bottled water after contamination is detected.
– Air quality alerts: Urge people with respiratory conditions to limit outdoor activity during high pollution or wildfire smoke events.
– Foodborne illness warnings and recalls: Identify contaminated products and advise disposal or return.
– Outbreak notices: Provide guidance on symptoms, testing, isolation, and when to seek care.
– Emergency evacuations or shelter-in-place orders tied to chemical spills or radiological events.
How alerts are issued and received
Official sources include local and state health departments, national public health agencies, and emergency management offices. Distribution channels are broad to ensure reach:
– Wireless Emergency Alerts (WEA) and other SMS-based systems
– Local TV and radio emergency broadcasts
– Official websites and email lists from health departments
– Push notifications from government apps and third-party alert apps
– Social media accounts run by public health agencies
What to do when you get an alert
– Verify the source: Look for messages from official agencies before acting on directions seen in social media posts.
– Follow clear, actionable instructions: If advised to boil water, do so for the recommended time; if told to stay indoors or evacuate, comply promptly.
– Protect vulnerable household members: Children, older adults, people with chronic illnesses, and those who are pregnant may need extra help or earlier action.
– Seek medical care as directed: Know where testing or treatment centers are located and when to call rather than visit in person.
Preparing in advance
Advance preparation reduces panic and improves outcomes. Practical steps:
– Sign up for local alerts and opt in to emergency notification systems.
– Keep an emergency kit with water, nonperishable food, medications, and a battery-powered radio.
– Maintain copies of important health documents and contact information for clinicians.
– Know multiple escape routes and a family communication plan for evacuations or separation.
– Learn basic first aid and have supplies for at least 72 hours.
Communications best practices for organizations
Public health messaging must be clear, concise, and actionable.
Effective strategies include:
– Pre-drafted templates for common scenarios to speed response
– Multilingual materials and accessible formats for people who are Deaf or have low vision
– Coordination with community leaders and healthcare providers to reach high-risk groups
– Transparent updates as new information becomes available to build trust
Avoiding misinformation
During alerts, misinformation can spread quickly. Rely on official channels and verified news outlets. If a rumor seems alarming, check the local health department website or official social accounts before sharing.
