    What the U.S. Government is Doing

    • The White House, CDC and Health and Human Services launched
    • CISA COVID Task Force webinar: “Provide Medical Care is in Critical Condition” December 2021
    • Use GSA’s Coronavirus Page, Spanish version for government-wide COVID-19 information.

    • FEMA and CISA are responsible for coordinating Emergency Support Function (ESF) efforts.  ESFs assist in coordinating federal interagency support for a federal response to an incident – in this case, to COVID-19. ESF #14 (Cross Sector Business and Infrastructure) was established to engage private sector and infrastructure owners and operators to help find and close gaps. It complements Sector Risk Management Agencies (SRMA) and other ESFs and is a mechanism for entities not aligned to an ESF or have other means of coordination to bring forward current issues and work toward solutions.

    • The CISA Insights: COVID-19 Disinformation Activity addresses disinformation campaigns and conspiracy theories appearing online, and provides the public steps on how to minimize the risk of spreading false or misleading content.
    • CISA’s COVID-19 Disinformation Toolkit helps State, local, tribal and territorial (SLTT) officials bring awareness to misinformation, disinformation, and conspiracy theories appearing online related to COVID-19’s origin, scale, government response, prevention and treatment.
    • To get groundtruth on rumors and facts please visit the FEMA Rumor Control page.  
    • The CDC has guidance for discontinuation of isolation for persons with non-test confirmed COVID-19 in a non- healthcare setting. Persons with COVID-19 who have symptoms and were directed to care for themselves at home may discontinue isolation under the following conditions:
      • At least three days (72 hours) have passed since recovery defined as resolution of fever without the use of fever-reducing medications and
      • Improvement in respiratory symptoms (e.g., cough, shortness of breath); and,
      • At least seven days have passed since symptoms first appeared.
    • FEMA’s guidance on addressing the shortage of Personal Protective Equipment (PPE) in Non-Healthcare setting.
    • DHS S&T has published a calculator to estimate how long the virus stays active on surfaces.

    Critical Infrastructure 

    • COVID-19 continues to pose a risk to the critical infrastructure workforce, to our National Critical Functions and to critical infrastructure companies and operations. Exposure of many frontline essential critical infrastructure workers to the SARS-CoV-2 virus has led to disproportionate illness and death in multiple sectors of critical infrastructure. Healthcare workers, law enforcement officers, firefighters, and workers in the transportation food and agriculture sectors are some of the workers that continue to risk exposure based on the nature of their job. The Strategies to Protect Our Critical Infrastructure Workforce provides risk mitigation strategies to reduce the negative impact of COVID-19 on the essential critical infrastructure workforce to support continued operation of our National Critical Functions and critical infrastructure companies and operators.
    • As the COVID-19 pandemic reaches another phase, with increased and protracted strains on the nation’s critical infrastructure and related National Critical Functions such as Provide Medical Care, CISA is undertaking a renewed push for cyber preparedness and resilience, as well as decision support for stakeholders within critical infrastructure sectors. The Provide Medical Care is in Critical Condition: Analysis and Stakeholder Decision Support to Minimize Further Harm document includes a collection of analysis done by the CISA COVID-19 Task Force through July 1,2021.
    • CISA's Identifying Critical Infrastructure During COVID-19 guidance and accompanying list are intended to support state, local, and industry partners in identifying the critical infrastructure sectors and the essential workers. Learn more about CISA's guidance or read our latest press release.
    • CISA developed the COVID-19 Recovery CISA Tabletop Exercise Package (CTEP) to assist private sector stakeholders and critical infrastructure owners and operators in assessing short-term, intermediate, and long-term recovery and business continuity plans related to the COVID-19 pandemic.
    • The Centers for Disease Control and Prevention (CDC) advises that critical infrastructure workers may be permitted to continue work following potential exposure to COVID-19, provided they remain asymptomatic and additional precautions are implemented to protect  them and the community. 
    • The Critical Infrastructure Operations Centers and Control Rooms Guide for Pandemic Response is geared towards all 16 critical infrastructure sectors. The guide provides considerations and mitigation measures for operation centers and control rooms, but can be applied further to any critical node that is required to continue functioning in a pandemic environment.
    • CISA, Health and Human Services (HHS), and the Federal Bureau of Investigation (FBI) jointly released a bulletin regarding potential threats to the health care community and resources and training on how to mitigate these threats.
    • CISA and Idaho National Laboratory (INL) have designed, developed, and deployed a capability for truckers and other commercial drivers in the U.S. to understand restrictions that they might encounter as they travel across the country. The Commercial Routing Assistance (CRA) tool merges coordinated and vetted data streams, plots multiple automated or custom routing options, and visualizes the wide variety of state regulations and actions that a driver would encounter along a route.  Read the fact sheet and learn more at

    • COVID-19 Checklist: Securing Your Business and Clinical IT: CISA has created a cybersecurity checklist to assist healthcare delivery organization in mitigating vulnerabilities and protecting against malicious actors. Hospitals and healthcare facilities are facing cyber-attacks of varied sophistication, including criminal networks and nation states. Implementing these protocols, and instilling a culture of digital vigilance, will allow HDOs to focus on COVID vaccine and overall patient care priorities instead of the consequences of a cyber-incident.
    • Domain-Based Message Authentication, Reporting and Conformance (DMARC): The DMARC product was created to call attention to an email authentication policy that protects against bad actors using fake email addresses disguised to look like legitimate emails from trusted sources. DMARC makes it easier for email senders and receivers to determine whether or not an email legitimately originated from the identified sender. Further, DMARC provides the user with instructions for handling the email if it is fraudulent. 
    • Multi-factor authentication (MFA): Multi-factor authentication is a layered approach to securing data and applications where a system requires a user to present a combination of two or more credentials to verify a user’s identity for login. MFA increases security because even if one credential becomes compromised, unauthorized users will be unable to meet the second authentication requirement and will not be able to access the targeted physical space, computing device, network, or database.
    • CISA released CISA Insights: Cybersecurity Perspectives Healthcare and Public Health (HPH) Response to COVID-19. This new resource provides observations and findings derived from an analysis of HPH entities enrolled in CISA's free vulnerability scanning service from March to November 2020. All HPH entities should review the assessment and take appropriate action to reduce vulnerability and maintain resilient cybersecurity practices.
