Abstract Achieving WHO air pollution guidelines is critical to reduce the health burden of pollution, which disproportionately affects socioeconomically disadvantaged populations and varies by sector, spatial distribution, seasonal trends.

The flu season is caused by a combination of different pathogens, including influenza viruses (IVS), that cause the flu, and non-influenza respiratory (NIRVs), common colds or influenza-like illness. These exhibit similar dynamics meteorological conditions have historically been regarded as principal modulator their epidemiology, with outbreaks in winter almost no circulation during summer, temperate regions. However, after emergence SARS-CoV2, late 2019, these were strongly perturbed worldwide: some infections displayed near-eradication, while others experienced temporal shifts occurred "off-season". This disruption raised questions regarding dominant role weather also providing an unique opportunity to investigate roles determinants on epidemiological IVs NIRVs. Here, we employ statistical analysis modelling test effects mobility viral dynamics, before COVID-19 pandemic. Leveraging surveillance data several viruses, from Canada USA, 2016 2023, found whereas pre-COVID-19 pandemic period, had strong effect, period effect was reduced played more relevant role. results, together previous studies, indicate behavioral changes resulting non-pharmacological interventions implemented control interfered other past dynamical equilibrium disturbed, perhaps permanently altered,

Association between air pollution, meteorological factors and hand, foot, and mouth disease incidence in Zhejiang Province: A Bayesian spatio-temporal modelling study

Temperature and humidity are known to influence seasonal patterns of hand, foot mouth disease (HFMD) transmission. However, the effect air pollution climate-air interaction on intensity HFMD epidemics is poorly understood. This study aims quantify exposure-response effects risk by level meteorological indicators in Zhejiang Province. A spatiotemporal Bayesian hierarchical model was used determine association between pollution, factors relative (RR) HFMD. The fitted monthly case data for 92 counties Province January 2013, December 2021. We assessed both linear pollutants HFMD, modification role extreme weather conditions nonlinear pollutant-HFMD association. 10 μg/m³ increase PM10 NO2 concentration raised 6.6% (RR = 1.066, 95% CI: 1.042, 1.092) 20.8% 1.208, 1.162, 1.256) respectively. negatively associated with O3 0.980, 0.968, 0.993), SO2 0.820, 0.776, 0.868) CO 0.770, 0.621, 0.956). Temperature, humidity, precipitation positively interacted most while wind speed had a negative effect. In higher temperature conditions, increased. Elevated levels amplified PM10, as did concentrations within certain range. Heavy rainfall intensified SO2, CO.

Air pollution exposure, SARS-CoV-2 infection, and immune response in a cohort of healthcare workers of a large university hospital in Milan, Italy

Several studies have examined the possible relationship between air pollutants and risk of COVID-19 but most returned controversial findings. We tried to assess association (short- long-term) exposure particulate gaseous pollutants, SARS-CoV-2 infections, immune response in a population healthcare workers (HCWs) with well-characterized individual data. collected occupational clinical characteristics all HCWs who performed nasopharyngeal swab (NPS) for detecting at Policlinico Hospital Milan (Lombardy, Italy) February 24, 2020 (day after first documented case our hospital) December 26, before start vaccination campaign). Each subject was assigned daily average levels matter ≤10 μm (PM10), nitrogen dioxide (NO2), ozone (O3) retrieved from quality monitoring station closest his/her residential address. Air pollution data were treated as time-dependent variables, generating person-days risk. Multivariate Poisson regression models fit evaluate rate positive NPS antibody titer among NPS-positive HCWs. Among 3712 included HCWs, 635 (17.1%) had least one NPS. A 10 μg/m3 increase NO2 concentration four days preceding associated higher testing [Incidence Rate Ratio (IRR) = 1.08, 95% confidence interval (CI): 1.01; 1.16)]. When considering 1 2019 annual average, we observed infection (IRR: 1.02, 95%CI: 1.00; 1.03) an increased (+2.4%, 1.1; 3.6%). Findings on PM10 O3 less consistent and, differently NO2, not confirmed multipollutant models. Our study increases body evidence suggesting active role confirms importance implementing reduction policies improve public health.

Old foes following news ways? - Pandemic-related changes in the epidemiology of viral respiratory tract infections

Abstract Introduction Following lockdown periods and restricting public health measures in response to the COVID-19 pandemic, respiratory tract infections (RTIs) rose significantly worldwide. This led an increased burden on children's hospitals compromising medical care of acutely chronically ill children. We characterized changes epidemiological pattern circulating viral infections. Methods assessed number patients with RTIs annual distribution virus detections between 2019 2022 based 4809 clinical samples (4131 patients) from a German pediatric tertiary care-center. investigated impact spectra viruses, coinfections, age, seasonality Results A fourfold increase was observed vs numbers doubling (vs 2021). In 2022, seasonal patterns circulation were less pronounced appeared have disappeared for Rhino/Enterovirus. SARS-CoV-2, Parainfluenza- human Metapneumovirus (2019 p < 0.01). Coinfections multiple viruses occurred more frequently since 2021 compared pre-pandemic years, especially younger children Conclusion Compared we dramatic incrementing spectrum predominance Rhino/Enterovirus – leading high rate hospital admissions, particularly conjunction other viruses. caused acute shortage may also be followed by virus-triggered secondary chronic diseases like asthma - rendering system.

Abstract Purpose: Studies have demonstrated important changes in the seasonality of pediatric respiratory illnesses since onset COVID-19 pandemic. The aim this study was to describe epidemiology childhood wheezing episodes before and after start pandemic relation their potentially associated environmental triggers. Methods: Files all children treated with salbutamol for a episode September October 2019, 2020 2021 were retrospectively reviewed. Infection epidemiology, daily concentrations air pollutants (NO 2 , O 3, PM 10 2.5 ) fungal spores collected over same time period. Results: In 2021, 298 observed compared 111 86 2019 (p<0.001). Compared significantly older (p<0.001), less likely history recurrent (p<0.001) required hospitalization (p=0.034). Adenovirus SARS-CoV-2 more prevalent as concentration 3 higher both while NO airborne lower (p<0.0001). Conclusion: A threefold increase autumn post-COVID (2021) pre-COVID (2019) together significant some viruses most pollutants. We hypothesize that abnormal surge may be related release restrictions rapid spread who exposed high levels pollution.
