Some surveillance centers also test the samples to identify their subtype. These are described as strains for influenza A (e.g., A H7N9) and lineages for influenza B (e.g., B Yamagata). This testing can use molecular detection, virus culture, or immunological methods.\\n\\n**Surveillance types:**\\n- Surveillance data from each country may come from sentinel sites or non-sentinel sites.\\n- Sentinel sites are health centers in a country that are selected to perform high-quality testing of cases: they test for flu subtypes and lineages in a routine and timely manner.\\n- They are also selected in a way that is aimed to be representative of the population. For example, they include health centers in both urban and rural areas, are general hospitals rather than specialist centers, and cater to a wide range of demographics.\\n- The WHO provides guidelines to countries for selecting centers which will be sentinel sites, using these criteria. The selection also depends on which centers have the resources for data collection, testing and reporting.\\n- Sentinel data can give a representative picture of trends across time in the country. But, since not all health centers and clinics are included, the data does not tell us about the total number of infections across the country. See also: World Health Organization. (1999). WHO Recommended Surveillance Standards. Second edition. https://web.archive.org/web/20220121021824/http://www.who.int/csr/resources/publications/surveillance/whocdscsrisr992.pdf\\n- Data on flu can also come from 'non-sentinel' sites. This includes other kinds of testing, which may be done at point of care, in universal testing, or during outbreak investigation. \\n-Some samples are not categorized as either sentinel or non-sentinel surveillance. These are included in the data for 'all types' of surveillance.\\n\\n**Data preparation steps:**\\n- Remove rows where confirmed cases by influenza strain do not sum as expected. Specifically:\\n \u00b7 Where all the influenza A strains do not sum to the total value given for influenza A\\n \u00b7 Where all the influenza B strains do not sum to the total value given for influenza B\\n \u00b7 Where influenza A + influenza B does not equal total influenza confirmed cases\\n- We follow the WHO\u2019s method to calculate the \u2018Share of tests that test positive (%).\u2019 They suggest using three possible denominators, in order of preference: \\n \u00b7 Number of negative influenza tests + number of positive tests\\n \u00b7 Number of specimens processed\\n \u00b7 Number of specimens received\\n- We follow the above approach at the country level. At the regional level, we do not consider the number of negative influenza tests as, historically, there is not much data available for this variable.\\n \u00b7 For example, there are many weeks where only one country has a value for negative influenza tests. Instead, we use specimens processed as the primary denominator as data for this is much more plentiful.\\n- We set the negative tests to NA where the sum of negative tests is 0, and the sum of the negative and positive tests does not equal the number of processed tests.\\n- We calculate an aggregate for the UK by summing data for England, N.Ireland, Scotland, and Wales. \\n- We calculate global and hemisphere aggregates by summing count variables and averaging rate variables.\\n- We calculate monthly from weekly variables by aggregating all weeks commencing in a particular month to that month. \\n- We remove all values for years with less than 10 data points.\\n- We remove all values for time series where the only values are 0 or NA.\\n- We do not show data for the most recent 21 days.

Data comes from national influenza surveillance and regional networks such as EUROFlu.\\n- The WHO defines acute respiratory illnesses (ARIs) as sudden/acute onset of \u22651 of the following symptoms: cough, sore throat, shortness of breath, coryza, and were judged by a clinician to be due to an infection.\\n- The WHO defines influenza-like illnesses (ILIs) as acute respiratory infections with a fever \u226538\u00baC, a cough, and onset of symptoms within the last ten days.\\n- The WHO defines severe acute respiratory infections (SARIs) as acute respiratory infections with a history of fever or measured fever of \u226538 C\u00b0, cough, with onset within the last ten days, requiring hospitalization.\\n- Some countries use older definitions of these conditions.\\n- Surveillance data from each country may come from sentinel sites, non-sentinel sites, or universal testing. However, the FluID dataset does not list the data under these separate categories, so we show them together.\\n- You can find more detail on the surveillance strategies, sampling methods, and definitions used by each country here: https://apps.who.int/iris/bitstream/handle/10665/352183/WHO-EURO-2022-4760-44523-63025-eng.pdf?sequence=1&isAllowed=y \\n\\n**Data preparation steps:**\\n- We remove values where the number of SARI cases is below the number of inpatients - by definition SARI cases should also be inpatients so there should always be more inpatients than SARI cases. \\n- We remove values where the number of ILIs or ARIs per 1000 outpatients is \u2265 1000.\\n- We remove values where the number of SARIs per 100 inpatients is \u2265 100.\\n- We remove all values for the time-series of ILIs or ARIs per 1000 outpatients where all values are \u2264 1 or \u2265 999.\\n- We remove all values for the time-series of SARIs per 100 inpatients where all values are \u2264 1 or \u2265 99.\\n- We calculate regional aggregates by summing count variables.\\n- We calculate monthly variables from weekly variables - all weeks commencing in a particular month are aggregated to that month.\\n- We remove all values for years with less than 10 data points.\\n- We do not show data for the most recent 21 days. Data covering the most recent 21 days is often adjusted and updated in the weeks following its release.",

Some surveillance centers also test the samples to identify their subtype. These are described as strains for influenza A (e.g., A H7N9) and lineages for influenza B (e.g., B Yamagata). This testing can use molecular detection, virus culture, or immunological methods.\\n\\n**Surveillance types:**\\n- Surveillance data from each country may come from sentinel sites or non-sentinel sites.\\n- Sentinel sites are health centers in a country that are selected to perform high-quality testing of cases: they test for flu subtypes and lineages in a routine and timely manner.\\n- They are also selected in a way that is aimed to be representative of the population. For example, they include health centers in both urban and rural areas, are general hospitals rather than specialist centers, and cater to a wide range of demographics.\\n- The WHO provides guidelines to countries for selecting centers which will be sentinel sites, using these criteria. The selection also depends on which centers have the resources for data collection, testing and reporting.\\n- Sentinel data can give a representative picture of trends across time in the country.
