• WHO is providing guidance on early investigations, which are critical in an outbreak of a new virus. The data
collected from the protocols can be used to refine recommendations for surveillance and case definitions, to
characterize the key epidemiological transmission features of COVID-19, help understand spread, severity,
spectrum of disease, impact on the community and to inform operational models for implementation of
countermeasures such as case isolation, contact tracing and isolation. Several protocols are available here. One
such protocol is for the investigation of early COVID-19 cases and contacts (the “First Few X (FFX) Cases and
contact investigation protocol for 2019-novel coronavirus (2019-nCoV) infection”). The protocol is designed to
gain an early understanding of the key clinical, epidemiological and virological characteristics of the first cases of
COVID-19 infection detected in any individual country, to inform the development and updating of public health
guidance to manage cases and reduce the potential spread and impact of infection.
RECOMMENDATIONS AND ADVICE FOR THE PUBLIC
If you are not in an area where COVID-19 is spreading or have not travelled from an area where COVID-19 is
spreading or have not been in contact with an infected patient, your risk of infection is low. It is understandable that
you may feel anxious about the outbreak. Get the facts from reliable sources to help you accurately determine your
risks so that you can take reasonable precautions (see Frequently Asked Questions). Seek guidance from WHO, your
healthcare provider, your national public health authority or your employer for accurate information on COVID-19
and whether COVID-19 is circulating where you live. It is important to be informed of the situation and take
appropriate measures to protect yourself and your family (see Protection measures for everyone).
If you are in an area where there are cases of COVID-19 you need to take the risk of infection seriously. Follow the
advice of WHO and guidance issued by national and local health authorities. For most people, COVID-19 infection
will cause mild illness however, it can make some people very ill and, in some people, it can be fatal. Older people,
and those with pre-existing medical conditions (such as cardiovascular disease, chronic respiratory disease or
diabetes) are at risk for severe disease (See Protection measures for persons who are in or have recently visited (past
14 days) areas where COVID-19 is spreading).
CASE DEFINITIONS
WHO periodically updates the Global Surveillance for human infection with coronavirus disease (COVID-19)
document which includes case definitions.
For easy reference, case definitions are included below.
Suspect case
A. A patient with acute respiratory illness (fever and at least one sign/symptom of respiratory disease (e.g.,
cough, shortness of breath), AND with no other etiology that fully explains the clinical presentation AND a
history of travel to or residence in a country/area or territory reporting local transmission (See situation
report) of COVID-19 disease during the 14 days prior to symptom onset.
OR
B. A patient with any acute respiratory illness AND having been in contact with a confirmed or probable COVID-
19 case (see definition of contact) in the last 14 days prior to onset of symptoms;
OR
