Evaluating and Testing Persons for Coronavirus Disease 2019 (COVID-19)

Summary of Recent Changes

Revisions were made on March 9, 2020, to reflect the following:

• Reorganized the Criteria to Guide Evaluation and Laboratory Testing for COVID-19 section

Revisions were made on March 4, 2020, to reflect the following:

• Criteria for evaluation of persons for testing for COVID-19 were expanded to include a wider group of symptomatic patients.

Limited information is available to characterize the spectrum of clinical illness associated with coronavirus disease 2019 (COVID-19). No vaccine or specific treatment for COVID-19 is available; care is supportive.

The CDC clinical criteria for considering testing for COVID-19 have been developed based on what is known about COVID-19 and are subject to change as additional information becomes available.

CDC Health Advisory

This is an official CDC Health Update

Update and Interim Guidance on Outbreak of Coronavirus Disease 2019 (COVID-19)

CDC continues to closely monitor an outbreak of respiratory illness caused by COVID-19 that was initially detected in Wuhan City, Hubei Province, China. This HAN Update provides a situational update and guidance to state and local health departments and health care providers.

Contact your local or state health department

Healthcare providers should immediately notify their local or state health department in the event of the identification of a PUI for COVID-19. When working with your local or state health department check their available hours.

Criteria to Guide Evaluation and Laboratory Testing for COVID-19

Clinicians should continue to work with their local and state health departments to coordinate testing through public health laboratories. In addition, COVID-19 diagnostic testing, authorized by the Food and Drug Administration under an Emergency Use Authorization (EUA), is becoming available in clinical laboratories. This additional testing capacity will allow clinicians to consider COVID-19 testing for a wider group of symptomatic patients.

Clinicians should use their judgment to determine if a patient has signs and symptoms compatible with COVID-19 and whether the patient should be tested. Most patients with confirmed COVID-19 have developed fever¹ and/or symptoms of acute respiratory illness (e.g., cough, difficulty breathing). Priorities for testing may include:

1. Hospitalized patients who have signs and symptoms compatible with COVID-19 in order to inform decisions related to infection control.

2. Other symptomatic individuals such as, older adults and individuals with chronic medical conditions and/or an immunocompromised state that may put them at higher risk for poor outcomes (e.g., diabetes, heart disease, receiving immunosuppressive medications, chronic lung disease, chronic kidney disease).

3. Any persons including healthcare personnel², who within 14 days of symptom onset had close contact³ with a suspect or laboratory-confirmed⁴ COVID-19 patient, or who have a history of travel from affected geographic areas⁵ (see below) within 14 days of their symptom onset.

There are epidemiologic factors that may also help guide decisions about COVID-19 testing. Documented COVID-19 infections in a jurisdiction and known community transmission may contribute to an epidemiologic risk assessment to inform testing decisions. Clinicians are strongly encouraged to test for other causes of respiratory illness (e.g., influenza).

Mildly ill patients should be encouraged to stay home and contact their healthcare provider by phone for guidance about clinical management. Patients who have severe symptoms, such as difficulty breathing, should seek care immediately. Older patients and individuals who have underlying medical conditions or are immunocompromised should contact their physician early in the course of even mild illness.

Recommendations for Reporting, Testing, and Specimen Collection

Clini1cians should immediately implement recommended infection prevention and control practices if a patient is suspected of having COVID-19. They should also notify infection control personnel at their healthcare facility and their state or local health department if a patient is classified as a PUI for COVID-19. State health departments that have identified a PUI or a laboratory-confirmed case should complete a PUI and Case Report form through the processes identified on CDC’s Coronavirus Disease 2019 website. State and local health departments can contact CDC’s Emergency Operations Center (EOC) at 770-488-7100 for assistance with obtaining, storing, and shipping appropriate specimens to CDC for testing, including after hours or on weekends or holidays.

For initial diagnostic testing for COVID-19, CDC recommends collecting and testing upper respiratory tract specimens (nasopharyngeal AND oropharyngeal swabs). CDC also recommends testing lower respiratory tract specimens, if available. For patients who develop a productive cough, sputum should be collected and tested for COVID-19. The induction of sputum is not recommended. For patients for whom it is clinically indicated (e.g., those receiving invasive mechanical ventilation), a lower respiratory tract aspirate or bronchoalveolar lavage sample should be collected and tested as a lower respiratory tract specimen. Specimens should be collected as soon as possible once a PUI is identified, regardless of the time of symptom onset. See Interim Guidelines for Collecting, Handling, and Testing Clinical Specimens from Patients Under Investigation (PUIs) for COVID-19 and Biosafety FAQs for handling and processing specimens from suspected cases and PUIs.

Interim Guidance for Collection and Submission of Postmortem Specimens from Deceased Persons Under Investigation (PUI) for COVID-19, February 2020

State and local health departments who have identified a Persons Under Investigation (PUI) should immediately notify CDC’s Emergency Operations Center (EOC) at 770-488-7100 to report a deceased PUI and determine whether testing for SARS-CoV-2, the virus that causes COVID-19, at CDC is indicated. The EOC will assist local/state health departments to collect, store, and ship specimens appropriately to CDC, including during afterhours or on weekends/holidays.

CDC is available for urgent consultation in the event that an autopsy on a COVID-19 PUI is being considered. CDC can be reached for urgent consultation by calling the EOC at 770-488-7100.

This interim guidance is based on what is currently known about COVID-19. The Centers for Disease Control and Prevention (CDC) will update this interim guidance as needed and as additional information becomes available.

The CDC is closely monitoring an outbreak of respiratory illness caused by a novel (new) coronavirus (named SARS-CoV-2); this illness is now called coronavirus disease 2019 or COVID-19. This virus was first identified in Wuhan, Hubei Province, China and it continues to spread. CDC is working across the Department of Health and Human Services and other parts of the U.S. government in the public health response to COVID-19.

Much is unknown about COVID-19. Current knowledge is largely based on what is known about similar coronaviruses. Coronaviruses are a large family of viruses that are common in many different species of animals, including camels, cattle, cats, and bats. Rarely, animal coronaviruses can infect people and then spread between people such as with MERS-CoV, SARS-CoV, and now with SARS-CoV-2, the virus that causes COVID-19. Most often, spread from a living person happens with close contact (i.e., within about 6 feet) via respiratory droplets produced when an infected person coughs or sneezes, similar to how influenza and other respiratory pathogens spread. This route of transmission is not a concern when handling human remains or performing postmortem procedures. Postmortem activities should be conducted with a focus on avoiding aerosol generating procedures, and ensuring that if aerosol generation is likely (e.g., when using an oscillating saw) that appropriate engineering controls and personal protective equipment (PPE) are used. These precautions and the use of Standard Precautions should ensure that appropriate work practices are used to prevent direct contact with infectious material, percutaneous injury, and hazards...
