During the winter of 1995, a space-time cluster of seven suspected cases of legionnaires’ disease occurred on Merseyside, involving three neighbouring health districts. A multidisciplinary investigation team was established but failed to obtain convincing evidence of an outbreak. Investigation of the seven cases confirmed two as sporadic cases; other infections were found to explain the remaini...

Purpose The study authors have proposed to highlight the main epidemiologic and prognostic aspects of digestive malignancies in the Dolj county population, justifying the need for permanent and detailed estimate of this phenomenon. Methods The authors of the study have proposed to outline a descriptive epidemiological panel, characteristic for the population groups at risk of developing gastric...

Background: Autism spectrum disorder (ASD) was once considered to be highly associated with intellectual disability and to show a characteristic IQ profile; with strengths in Performance over Verbal abilities and a distinctive pattern of ‘peaks’ and ‘troughs’ at the subtest level. However, there is little data from epidemiological studies. Method: Comprehensive clinical assessments were conduct...

Rich meta-epidemiological data sets have been collected to explore associations between intervention effect estimates and study-level characteristics. Welton et al proposed models for the analysis of meta-epidemiological data, but these models are restrictive because they force heterogeneity among studies with a particular characteristic to be at least as large as that among studies without the...

The article begins by describing a dog with characteristic symptoms of visceral leishmaniasis. A serum sample from this animal was positive by indirect immunofluorescence (IIF) performed in anti-Leishmania total IgG in 1999. Tissues from the same dog were also positive by polymerase chain reaction (PCR) in 2004, identifying Leishmania DNA in the cerebellum, liver, kidney, and intestine. This is...

Severe acute respiratory syndrome coronavirus 2 (SARS CoV-2) infection is rapidly evolving as a serious global pandemic. The present study describes the clinical characteristics of SARS CoV-2 patients. samples were subjected to reverse-transcription polymerase chain reaction or Rapid Antigen test for diagnosis CoV-2. A cohort 3745 patients with confirmed in tertiary care center New Delhi, India...

Two hundred eight of 648 (32%) diarrheal stool samples collected from hospitalized children under 5 years of age during a 3-year period (1999, 2000, and 2002) in the city of Salvador, in the state of Bahia, Brazil, were rotavirus positive. One hundred sixty-four of 208 (78.8%) rotavirus-positive samples had genotype G9 specificity, predominantly in association with P[8]. Other specificities det...

1 Characteristic 0 We start with a basic question: given a polynomial f ∈ C[z1, · · · , zn] with a singularity at 0, how can we measure the “singularness” of this polynomial in a precise way? In other words: we can look at various singularities and see intuitively that some singularities are worse than others. For instance, it feels like a transverse self-intersection is probably not as bad as ...

The paper examines the possibility of using an alternative approach to predicting statistical indicators a new COVID-19 virus type epidemic. A systematic review models for epidemics infections in foreign and Russian literature is presented. accuracy SIR model spring 2020 wave epidemic forecast Russia analyzed. As modeling spread model, CIR discrete stochastic proposed based on balance at curren...
