Seasonal influenza in Spain: Clinical and economic burden and vaccination programmes.

A literature review has been carried out to analyse the clinical burden, the economic impact of influenza and the efficiency of influenza vaccination programmes in Spain. The average incidence rate of influenza in Spain is 2,069 cases per 100,000 inhabitants, with a significant impact on mortality and a reduction of health-related quality of life. In terms of its associated costs, influenza causes a significant burden on primary care, hospitals, treatments and absences from work every year, which could total one billion euros per year.

Fate of classical faecal bacterial markers and ampicillin-resistant bacteria in agricultural soils under Mediterranean climate after urban sludge amendment.

The use of sewage sludge or biosolids as agricultural amendments may pose environmental and human health risks related to pathogen or antibiotic-resistant microorganism transmission from soils to vegetables or to water through runoff. Since the survival of those microorganisms in amended soils has been poorly studied under Mediterranean climatic conditions, we followed the variation of soil fecal bacterial markers and ampicillin-resistant bacteria for two years with samplings every four months in a split block design with three replica in a crop soil where two different types of biosolids (aerobically or anaerobically digested) at three doses (low, 40; intermediate, 80; and high, 160Mg·ha(-1)) were applied. Low amounts of biosolids produced similar decay rates of coliform populations than in control soil (-0.
