Introduction

This Reporting Protocol describes data collection for influenza, COVID-19, and other respiratory viruses

(such as RSV or new viruses of public health concern) in the EU/EEA and wider WHO European Region.

Data collection is integrated for most datasets in line with the operational considerations for respiratory

virus surveillance in Europe.

Aim

To support the timely and complete reporting of key information for surveillance of respiratory virus

such as for influenza, COVID-19, RSV or new viral diseases of public health concern.

Objectives

Weekly outputs focus mainly on Objectives 1,2 and 3 (outlined in Table 1). Objectives 4 and 5 can be

addressed with detailed analysis using a combination of the reported record types.

1. Monitor the intensity, geographical spread and temporal patterns of influenza, COVID-19,

and other respiratory virus infections to inform mitigation measures.

2. Monitor severity, risk factors for severe disease, and assess the impact on healthcare systems

of influenza, COVID-19, and other respiratory virus infections to inform mitigation measures.

3. Monitor changes and characteristics of circulating and emerging respiratory viruses,

particularly virological changes of influenza viruses, SARS-CoV-2, and other respiratory viruses

to inform treatment, drug, and vaccine development.

4. Describe the burden of disease associated with influenza, COVID-19, and other respiratory

virus infections.

5. Assess vaccine effectiveness against influenza, COVID-19, and other respiratory virus

infections where locally feasible.

Record types

All record types except INFLANTIVIR and NCOVVARIANT are integrated record types that are based on

reporting of a syndrome (ILI, ARI or SARI) and/or the reporting of lab-confirmed infections by

pathogen(s) specified by the relevant variable. Table 1 provides an overview of data collection of

sentinel and non-sentinel data and indicates how these data map to the objectives outlined above.

Reporting of sentinel data should be prioritised. Non-sentinel data should be reported as complementary

data, particularly if sentinel data is missing, insufficient or not representative.

The following record types exist in TESSy. Included variables for each record type are outlined below

in the annex.

1. INFLCLINAGGR for reporting of weekly age-disaggregated primary care syndromic data

(ILI/ARI) and qualitative indicators.

2. RESPIAGGR for reporting of age-disaggregated counts of laboratory-confirmed detections

and tests from sentinel and non-sentinel surveillance system by week and pathogen.

3. RESPISEVERE for reporting of age-disaggregated counts of hospital, ICU indicators (new

admissions, current inpatients) and deaths due to respiratory illness associated with the

pathogen aggregated by week, indicator, and pathogen.

4. RESPISURV for reporting of case-based data by pathogen for cases meeting one or more of

the following criteria:

o Data on severe cases (hospitalised, requiring respiratory support, ICU admission or

fatal) that are not covered by existing SARI surveillance systems (and therefore

Page 7 of 96

reported into SARISURV). This includes data from laboratory-based confirmed cases in

hospital settings previously reported to INFLSARI.

o COVID-19 cases that have been sequenced or genotyped and for which additional

epidemiological information are available to facilitate variant severity assessment,

including whether the cases experienced a severe outcome and the case’s vaccination

information. If this information is not available, then reporting via GISAID (or

optionally NCOVVARIANT – see below) is sufficient.

5. INFLSARIAGGR for reporting of age-disaggregated data from SARI surveillance, including

weekly counts of hospital admissions, hospital catchment population, SARI deaths, pathogen-

specific tests and detections.

6. SARISURV for case-based reporting of SARI cases.

7. SARISURVDENOM for reporting of weekly denominators for the record type SARISURV

(hospital catchment population and admissions, by age group). 8. INFLANTIVIR for reporting of strain-based influenza virus characterisation and antiviral

susceptibility data.

9. NCOVVARIANT (optional if GISAID data is reported) for weekly aggregated reporting of

SARS-CoV-2 variants of interest and of concern.

Case definitions

Case definition: Cases should be reported according to the current EU case definition. Data on

probable and possible cases are not collected.

Please note that:

1. All data collected are shared with the World Health Organisation – Regional Office for Europe

(WHO/Europe) on a weekly basis to fulfil Member States reporting requirements to WHO.

Duplicate reporting to WHO HQ is therefore not required.

2. If data have not been uploaded in TESSy and approved on time it will not be possible to

include the data in weekly reports. If you are unable to meet this deadline, please contact the

ECDC Respiratory Viruses surveillance team ([email protected] with

[email protected] in copy).

3. Case-based data on human infections with zoonotic influenza viruses should be reported to

INFLZOO metadata set and aggregated to INFLZOOAGGR. A separate reporting protocol is

available.

Reporting to TESSy

When, what and how to report

Deadline for reporting:

Wednesday 23:59 CET for all record types. If you are unable to meet this deadline, please contact the

ECDC Respiratory Viruses surveillance team ([email protected] and copy

[email protected]).

Preparing data

Data may be entered directly in EpiPulse Cases (TESSy) for individual records (‘Manually create a

record’). For any batch reporting by file upload (CSV or XML format) please note that once the data

has been exported from your national database it needs to be in a format that TESSy can accept (see

‘checking metadata’).

Checking metadata

The EpiPulse Cases (TESSy) metadata define the fields and valid data formats for input for a given

subject.

To ensure data can be saved correctly in EpiPulse Cases (TESSy), please check the data are

correctly formatted according to the most recent metadata set.

Changes to the metadata for the subject of this Reporting Protocol are described in:

• Changes to current metadata – changes since the last Reporting Protocol.

• Annex Metadata change history – all preceding changes.

It is especially important to focus on:

Field formats

Many fields require that data are formatted in a specific way. For example, dates must be in the

YYYY-MM-DD format; dates in the DD/MM/YYYY format will be rejected.

Coded values

Some fields only permit the use of specific values (coded values). For example, M, F, UNK, or

Other are the coded values for Gender and any other value in a Gender field will be rejected.

The metadata file contains all the definitions and rules you need to comply with to format your data

correctly for every subject (usually a disease). The file can be downloaded as an Excel file from the

EpiPulse Cases (TESSy) documents website.

By filtering the fields in the file by subject, you can see the fields required for your subject and the rules

applying to these fields.

The Tessy User Guide provides an overview of how you work with the metadata file, and the TESSy

user documentation provides in-depth details on metadata.

Submitting your data

The TESSy / Upload page is accessible from the EpiPulse > Report > Cases menu. Data are submitted

through the EpiPulse Cases web interface (go to Upload). Previously reported data can be found

through the review tab. The TESSy / Review page is accessible from the EpiPulse > Manage > Edit

case / Case validation menu.

Page 10 of 96

The EpiPulse Cases (Tessy) User Guide provides an overview of how you submit files to TESSy and

in-depth descriptions of all the upload methods.

Finalising your submission

The compliance of your data with the validation rules in the metadata is checked automatically during

the data upload process.

The result of your upload – i.e., rejected or validated – is displayed immediately after the check in the

Validation details webpage has completed. Please review the result carefully:

• If your file has been rejected, there will be a message explaining each instance of non-

compliance with the metadata that you need to correct.

• If your file has been validated, there might be warnings and remarks relating to possible data

quality issues or to potential overwriting of existing records that you should consider.

When you file has been validated and you are satisfied that all corrections have been made, please

ensure prompt approval – unapproved uploads can block the approval of other uploads.

• The EpiPulse Cases (TESSy) user documentation provides information on reviewing validation

results and adjusting reporting periods to avoid overwriting existing records.

• General training and guidance on reporting is available on the EpiPulse Cases (TESSy) website. A

training video on reporting COVID-19 data is available in the ECDC virtual academy.

SARISURVDENOM metadata

SARISURVDENOM is used for reporting of weekly denominators for the record type SARISURV

(hospital catchment population and admissions, by age group).

Several options may be used to determine the proportion of the population covered by the selected

sentinel hospitals:

1. If the information on the hospitals’ catchment population is available, it should be

provided directly.

2. If the information on hospitals’ catchment population is not available, it should be

estimated. Two approaches to calculating denominators are provided below.

a. Estimate based on the median weekly number of all-cause hospitalisations in the

previous years: Proportion of patients discharged from the selected hospitals among all

hospitals in the region multiplied by the region population. Catchment population = region

population * (number patients discharged from selected hospitals/number of patients

discharged from all hospitals in region). The catchment population estimation should first

be done for each hospital and estimates from hospitals should be summed up, so that the

estimates apply to the full surveillance system.

b. Estimate based on the number of beds: in an urban area, the catchment population

can be estimated by taking into account the population of the city, the number of hospitals

in the city and the number of beds in a hospital. Coefficients should be attributed to each

hospital in the city depending on their activity estimated by the number of beds. For

example, in a city with 3 hospitals, if hospital A has 50 beds, the coefficient to be applied

will be 0.5, if hospital B has 125 beds, the coefficient will be 1.25 and if hospital C has 75

beds, the coefficient will be 0.75, so:

Catchment population = City population*coefficient (based on the number of beds)/Number of

hospitals in the city.

In this approach, the estimation of population coverage of hospitals should first be done for each

hospital and estimates from hospitals should be summed up, so that the estimates apply to the full

surveillance system.

Common TESSy variables

Record type (mandatory)

Field: RecordType

Coding: SARISURVDENOM

The record type defines the structure and the format of the data reported. The record types are defined

by ECDC and are related to the subject. Only valid combinations of subject, record type and data source

are accepted.

Record type version

Field: RecordTypeVersion

Coding: Numeric

The version of the record type defines the current structure of the data reported. If no

RecordTypeVersion is provided in the batch, it is set automatically with current version of the Record

type (Table 2). This variable is not mandatory as TESSy concludes the record type version from the

metadata set indicated by default. However, RecordTypeVersion is required when no metadata set is

provided at upload or when a RecordTypeVersion, other than the current one, needs to be used.

Subject (mandatory)

Page 58 of 96

INFLSARIAGGR metadata

INFLSARIAGGR is used for reporting of aggregated data on SARI cases and underlying population

denominators for calculation of total and age-specific notification rates and proportions. Aggregated

data should be reported weekly.

The epidemiological variables to collect include:

• All-cause hospital admissions, by age group (denominator);

• Hospital catchment population, by age group (denominator);

• SARI hospitalisations, by age group (numerator);

• SARI hospitalisation deaths, by age group (numerator);

• SARI admissions to intensive care, by age group (numerator);

• SARI specimens tested for influenza, respiratory syncytial virus (RSV) and SARS-CoV-2, by age

group (denominator);

• SARI specimens positive for influenza, RSV and SARS-CoV-2, by age group (numerator);

• SARI specimens positive for influenza by virus (sub)type and lineage (numerator).

Common TESSy variables

Record type (mandatory)

Field: RecordType

Coding: INFLSARIAGGR

The record type defines the structure and the format of the data reported. The record types are defined

by ECDC and are related to the subject. Only valid combinations of subject, record type and data source

are accepted.

Record type version

Field: RecordTypeVersion

Coding: Numeric

The version of the record type defines the current structure of the data reported. If no

RecordTypeVersion is provided in the batch, it is set automatically with current version of the Record

type (Table 2). This variable is not mandatory as TESSy concludes the record type version from the metadata set indicated by default. However, RecordTypeVersion is required when no metadata set is

provided at upload or when a RecordTypeVersion, other than the current one, needs to be used.

Subject (mandatory)

Field: Subject

Coding: INFLSARI

The subject describes the disease to be reported.

Data source (mandatory)

Field: DataSource

Coding: Pre-assigned as CountryCode-INFLSARIAGGR to each country; can be modified by National

Coordinator; countries reporting aggregated data through the new SARI surveillance stream

should change data source to "CountryCode-SARISURVAGGR"

The data source specifies the surveillance system from which the data originate and is generated and

revised/updated by the national focal point in each Member State. The descriptions of the surveillance

systems submitted to TESSy (section Data Sources) should include details about case definition used

and should be kept up to date and will be used to assist with data interpretation. If country is reporting

Annex: INFLSARIAGGR metadata

Page 59 of 96

cases that do not follow strict WHO case definition (see Definitions), that should be stated in

DataSource.

Reporting country (mandatory)

Field: ReportingCountry

Coded value list: [Countries]

Coding: International organization for standardization (ISO) 3166-1-alpha-2, (two-letter code)

This variable identifies the country reporting the aggregate dataset.

Date used for statistics (mandatory)

Field: DateUsedForStatistics

Coding: yyyy-Www

The reference date used for standard reports that is compared to the reporting period. The date used

for statistics should be preferably the week of admission to hospital, but can be any date that the

reporting country finds applicable, e.g. date of admission, date of notification, date of diagnosis or any

other date.

Epidemiological variables

Total number of SARI reporting sites

Field: NumSariRepSites

Coding: Numeric

Total number of sites reporting SARI hospitalisations. Should be adjusted according to the number of

hospitals reporting. (E.g. if a country has 2 hospitals each with 50,000 catchment population and in

week X only 1 hospital reports, please report NumSariRepSites = 1 and the denominator to be 50,000

and not 100,000)

Required: True (warning)

Reporting fraction (alternative)

Field: ReportingFraction

Coding: Numeric (decimal)

Proportion of SARI admissions at the participating hospitals that are reported in the current week. This

is an alternative variable, to account for the fact that some hospitals might report only a fraction of the

SARI cases (eg. Only cases admitted on two specific days of the week). Catchment population and all-

cause admissions should not be adjusted for this reporting fraction (e.g. if a hospital has a catchment

population of 50,000, the reported catchment population should be 50,000, even if SARI admissions

reported cover only specific days of the week).

Geographic spread of influenza (mandatory)

Field: GeographicSpread

Coded value list: [GeographicSpread]

Coding: L = Local

NO = No activity

R = Regional

S = Sporadic

UNK = Unknown (no information available)

W = Widespread

Annex: INFLCLINAGGR metadata

Page 79 of 96

Geographic spread is a measure of the geographic distribution of reported detections of influenza

viruses in specimens from sentinel or non-sentinel sources.

• No activity: No influenza viruses detected (other than detections from cases with recent

known history of travel).

• Sporadic: Influenza viruses sporadically detected.

• Local(ised): Circulation of influenza viruses limited to one administrative unit in the MS (or

reporting site);

• Regional: Circulation of influenza viruses appearing in multiple but less than 50% of the

administrative units of the MS (or reporting sites)*.

• Widespread: Circulation of influenza viruses appearing in 50% or more of the administrative

units of the MS (or reporting sites).

*Regional activity is generally not used for MS with a small population (<5 M) and covering a small

geographic area."

Intensity of influenza

Field: Intensity

Coded value list: [Intensity]

Coding: B = Baseline

H = High

L = Low

M = Medium

UNK = Unknown (no information available)

VH = Very High

Intensity is a measure of influenza activity within individual MS.

• Baseline or below epidemic threshold: ILI or ARI rates that are very low and at levels usually

seen throughout the inter-epidemic period.

• Low: ILI or ARI rates that are relatively low compared to rates from historical data but higher

than the baseline. Influenza virus detections have been reported.

• Medium: ILI or ARI rates that are similar to rates usually observed, based on historical data.

Influenza virus detections have been reported.

• High intensity: ILI or ARI rates that are higher than rates usually observed, based on historical

data. Influenza virus detections have been reported.

• Very high: ILI/ARI rates that are much higher than rates usually observed, based on historical

data. Influenza virus detections have been reported.

Intensity level can be defined using two approaches:

a) Qualitative indicator based on a national expert evaluation of intensity. For MS that report intensity

as a qualitative indicator using an expert evaluation of intensity, they can do so by reviewing the weekly

ILI or ARI rates and comparing them to rates in previous seasons. It is recommended to take influenza

virus detections into account as well.

b) Semi-quantitative indicator using historical data (e.g. Moving Epidemic Method, WHO or

other methods). For MS that report intensity as a semi-quantitative indicator, they can do so by a

predefined method. It is recommended to take influenza virus detections into account as well as

syndromic data.

Trend of influenza

Field: Trend

Coded value list: [Trend]

Coding: D = Decreasing

I = Increasing

S = Stable

Annex: INFLCLINAGGR metadata

Page 80 of 96

UNK = Unknown (no information available)

Trend is a measure of changes in influenza activity (based on ILI and/or ARI rates and lab-confirmed

influenza cases) in comparison to the previous week or weeks.

• Increasing: ILI and/or ARI consultation rates are substantially higher compared to the previous

week(s) and influenza viruses must have been detected in specimens from sentinel and/or non-sentinel

sourcesab.

• Stable: ILI and/or ARI consultation rates are similar compared to the previous week(s). Influenza

viruses must have been detected in specimens from sentinel and/or non-sentinel sourcesb.

• Decreasing: ILI and/or ARI consultation rates are substantially lower compared to the previous

week(s). Influenza viruses must have been detected in specimens from sentinel and/or non-sentinel

sources ab.

a) Multiple prior weeks should be used to assign increasing or decreasing trend when intensity is

“Baseline or below epidemic threshold” and in the absence of such evidence default to stable; b)

Sentinel data are preferred but if these are not available non-sentinel data may be used.

Impact

Field: Impact

Coded value list: [Impact]

Coding: B = Baseline

H = High

L = Low

M = Medium

UNK = Unknown (no information available)

VH = Very High

Impact is a measure of resultant hospitalization of the epidemic within individual MS.

• Baseline: influenza related hospitalizations (SARI or laboratory confirmed hospitalizations, as counts, percentage positivity or rates) at levels usually seen throughout the inter-epidemic

period. • Low: influenza related hospitalizations (SARI or laboratory confirmed hospitalizations, as

counts, percentage positivity or rates) that are relatively low compared to rates from historical data but higher than the baseline.

• Medium: influenza related hospitalizations (SARI or laboratory confirmed hospitalizations, as

counts, percentage positivity or rates) that are similar to rates usually observed, based on historical data.

• High: influenza related hospitalizations (SARI or laboratory confirmed hospitalizations, as counts, percentage positivity or rates) that are higher than rates usually observed, based on

historical data.

• Very high: influenza related hospitalizations (SARI or laboratory-confirmed hospitalizations, as counts, percentage positivity or rates) that are much higher than rates usually observed, based

on historical data.

NCOVVARIANT metadata

NCOVVARIANT is used for reporting of aggregated data on variants of interest and of concern per

week.

Common TESSy variables

Record Identifier (mandatory)

Field: RecordId

Coding: Text (max 80 characters)

The record identifier is provided by the Member State. It must be

▪ unique within the national COVID-19 disease surveillance system

▪ anonymous.

Record type (mandatory)

Field: RecordType

Coding: NCOVVARIANT

The record type defines the structure and the format of the data reported. The record types are defined

by ECDC and are related to the subject. Only valid combinations of subject, record type and data source

are accepted.

Record type version

Field: RecordTypeVersion

Coding: Numeric

The version of the record type defines the current structure of the data reported. If no

RecordTypeVersion is provided in the batch, it is set automatically with current version of the Record

type (Table 2). This variable is not mandatory as TESSy concludes the record type version from the

metadata set indicated by default. However, RecordTypeVersion is required when no metadata set is

provided at upload or when a RecordTypeVersion, other than the current one, needs to be used.

Subject (mandatory)

Field: Subject

Coding: NCOVVARIANT

The subject describes the disease to be reported.

Data source (mandatory)

Field: DataSource

Coding: Pre-assigned as CountryCode-NCOVVARIANT to each country; can be modified by National

Coordinator

The data source specifies the surveillance system from which the data originates and is generated and

revised/updated by the national contact point for surveillance in each Member State. The descriptions

of the surveillance systems submitted to TESSy should be kept up to date and will be used to assist

with data interpretation.

Reporting country (mandatory)

Field: ReportingCountry

Coded value list: [Countries]
