Through a weekly all-cause mortality surveillance system, we observed in France major excess from March to May 2020, concomitant with the coronavirus disease (COVID-19) epidemic. The was 25,030 deaths, mainly among elderly people. Five metropolitan regions were most affected, particularly Île-de-France and Grand-Est regions. Assessing related COVID-19 is complex because of potential protective effect lockdown period on other causes mortality.

Since the end of November 2023, European Mortality Monitoring Network (EuroMOMO) has observed excess mortality in Europe. During weeks 48 2023–6 2024, preliminary results show a substantially increased rate 95.3 (95% CI: 91.7–98.9) all-cause deaths per 100,000 person-years for all ages. This is seen adults aged 45 years and older, coincides with widespread presence COVID-19, influenza respiratory syncytial virus (RSV) many countries during 2023/24 winter season.

Fire blight is a disease affecting Maloideae caused by the necrogenic bacterium Erwinia amylovora , which requires type III protein secretion system (TTSS) for pathogenicity. Profiles of methanol‐extractable leaf phenolics two apple ( Malus × domestica ) genotypes with contrasting susceptibility to this were analyzed HPLC after infection. Some qualitative differences recorded between constitutive compositions but in both them dihydrochalcones accounted more than 90% total phenolics....

Comparing age and sex differences in SARS-CoV-2 hospitalization mortality with MERS-CoV, seasonal coronaviruses, influenza other health outcomes opens the way to generating hypotheses as underlying mechanisms driving disease risk. Using 60-year-olds a reference group, we find that relative rates of associated emergent coronaviruses are lower during childhood start increase earlier (around puberty) compared coronaviruses. The changing distribution risk by for emerging pathogens appears...

Implemented 10 years ago, the French syndromic surveillance system Oscour, based on emergency departments, has been assessed using four major evaluation criteria in surveillance: stability and regularity of data transmission, coverage at national level, quality, particularly for medical information utility public health surveillance. In 2014, about 40,000 daily attendances are extracted automatically from 600 ED departments located all over territory, covering 80% attendances. About 12,800...

Maps of influenza activity are important tools to monitor epidemics and inform policymakers. In France, the availability a high-quality data set from Oscour® surveillance network, covering 92% hospital emergency department (ED) visits, offers new opportunities for disease mapping. Traditional geostatistical mapping methods such as Kriging ignore underlying population sizes, not suited non-Gaussian do account uncertainty in parameter estimates.Our objective was create reliable weekly...
