This study aims to investigate this increase, contextualizing disease surveillance data with denominator data, which is not routinely available, i. We collected the testing data for Legionella spp. The of positive tests increased proportionally to the of tests performed; hence, the positivity remained stable. However, the cause of the increase in test volume is unclear and has a large impact on the interpretation of the positivity curve.

Further, the test outcome was found to be dependent on regional determinants, and the diagnostic method applied. The lack of understanding if and at which stage LD is considered in current case management of pneumonia patients limits the interpretation of observed heterogeneities in incidence or underestimation of LD in Switzerland. The absence of or non-adherence to existing guidelines and the heterogeneity in diagnostic testing hampers the comparison of data in the Swiss public health context.

Therefore, diagnostic procedures should be harmonised across Switzerland and adherence to national LD management guidelines supported. Legionella spp. Infections with Legionella spp. In recent years, person-to-person transmission was also suspected [ 3 ]. Cases can occur sporadically, in clusters and large outbreaks. Although Legionella spp. In Europe in1. In the same year, the US reported cases, corresponding to 2.

Case s have been increasing in European countries and the US in the past years. In Switzerland, infections with Legionella spp. While all laboratory-confirmed infections are notifiable, only LD cases—cases with pneumonia—are considered as confirmed or probable cases, which are reflected in the s published in official statistics. The case s continuously increased from in to cases in [ 6 ]. It has been hypothesised that the increase in incidence is due to augmented susceptibility in the population, climate change or changes in energy policies [ 46 ]. Furthermore, several studies link weather and climate, namely warm and humid conditions, to LD incidence [ 9101112 ].

Efforts in energy saving, resulting in recommendations to lower temperature thresholds of potable warm water, could have the drawback to promote conditions which favour Legionella spp. Conversely, the increase in case s could also be an artefact.

Increased awareness of physicians could lead to increased testing and hence, to more cases found. The incidence of legionellosis is generally thought to be underestimated; a study from Germany in estimated about 15, to 30, cases of sporadic LD annually [ 14 ]. Improvements in diagnosis and surveillance could lead to higher but more accurate case s [ 1516 ].

We collected testing data of 14 Swiss diagnostic laboratories between and to evaluate the effect of changes in test s and diagnostic procedures on the notification s in Switzerland. Using this data, we calculated the positivity of Legionella spp.

The methods of a positivity study have been described in detail elsewhere [ 17 ]. In brief, we collected testing data from 14 Swiss diagnostic laboratories. The laboratories were selected inbased on providing most LD notifications in the prior 10 years. We collected data on all tests performed for Legionella spp. The test result was reported by the laboratories and not ased by the study team, hence the application and description of the case definition were not needed in this study. Repeated tests were defined as more than one test performed per patient and disease episode.

The definition of a disease episode was complex given the laboratory data available; the process is described in the Supplementary Material see Supplementary File 1 and Figure S1 for details. We use the term positivity as the proportion of the of positive tests to the total of tests performed for Legionella spp. The positivity was calculated for different age and sex groups, test methods, sample materials, spatial region and laboratory and temporal annual and seasonal trends. The main outcome, the annual positivity, was age- and sex-adjusted using direct standardisation with the sample population — as the reference population.

We used mixed-effect logistic regression to for clustered data to analyse the determinants for a positive test result. Univariable logistic regression was used to test the association between the test result and test year, season, time trend, sex, age group, laboratory, test method, sample material and greater region Table 1.

The time trend was a continuous variable combining test month and test year. with most observations were chosen as referenceexcept for the seasonality first month of the year. Overview of the variables used in the regression models on a positive test result for Legionella spp. We constructed two multivariable mixed-effect logistic regression models, both including the variables sex, age group, season, time trend, and test method. One model included the region and the other the laboratory as random effect. The study was conducted under the Epidemics Act SR The data, provided by laboratories, were anonymised for analysis.

The 14 laboratories provided a total ofobservations, including positive tests. Three laboratories could not provide data for the entire study period — due to changes in their laboratory information system and data storage. Applying pre-defined exclusion criteria residence outside of Switzerland, inconclusive testtests performed outside of the study periodwe excluded observations positives and with an inconclusive or missing test result. Additionally, 13 positives entries were excluded, for which information on either sex or age was missing.

We excluded duplicates positives from the dataset. In total 1. Lastly, 13, repeated tests positives were excluded. The final dataset comprisedpositives observations. We compared the of positive test in our dataset to the NNSID notification s as notified by our selected laboratories. As noted above, the published notification s only reflect LD cases while the positive test in our dataset reflect all legionellosis cases.

The biggest difference in s was observed in with a relative difference of The average relative difference was Generally, the annual case from all participating laboratories combined was higher in our dataset than in the NNSID data. The figures in the bars correspond to the of observations; the relative difference between them is denoted as the percentages above the bars. This proportion remained constant across the years. The yearly age- and sex-adjusted positivity decreased marginally from 1. Time trend in test volume, cases and positivity.

Across Looking for hot sex Switzerland years, the positivity started increasing in May and peaked in August and September reaching 2. The seasonality of the positivity is a direct result of the contrasting seasonality of the of tests performed and the of positive test obtained Supplementary Figure S2. Conversely, more than three times as many cases were reported in September compared to February.

The seasonality persisted across all age groups, both genders and all regions. It is most strongly reflected in tests performed using urinary antigens. PCR and culture-based tests do not show any clear seasonal pattern for the of tests performed and the of positive cases, also explained by small s. The positivity varies strongly by gender and age group. Males have an overall higher positivity compared to females 1. The positivity increases with age and is highest among 45—year-olds 2. The positivity of males aged 5—14 years old is the only exception to this pattern with a positivity of 1.

The majority of patients tested were males This proportion remained stable across the study period — Overall, most tests were performed in the age group of 75—year-olds Least tests were performed in the age groups of infants 0—4adolescents 5—14 and young adults 15—24 with 0. The difference in sex distribution was small but statistically ificant for all greater regions range Of the 14 laboratories in our dataset, 11 were hospital laboratories ing for However, the three private laboratories may also perform diagnostics for hospitalised patients.

The laboratories performed diagnostics mainly for patients with residency in proximity to the laboratory site.

Hence, any information on regions is heavily influenced by the selection of laboratories. The positivity in the greater regions across all years ranged from 0. Representation of the seven greater regions of Switzerland displayed as grey area of the positivity for Legionella spp.

The expected cases were calculated based on the relative population size of each region to the overall Swiss population and the proportion of each region of all cases in our dataset. The average for all greater regions was tests perpopulation. The of tests performed increased in all regions between and Supplementary Figure S5. This distribution remained stable, even when disregarding the laboratories not providing data for the entire study period.
