“…Un nuovo sottotipo di virus influenzale A (H1N1) è stato descritto dal 24 marzo al 24 aprile 2009 a Città del Messico e si è diffuso rapidamente in tutto il mondo [2]. L'11 giugno 2009 l'Organizzazione Mondiale della Sanità (OMS) ha dichiarato lo stato di pandemia mondiale [3]. L'infezione da virus influenzale può causare polmonite primaria che può essere complicata da una sovra-infezione batterica o esacerbare una sottostante malattia cronica [4].…”

“…A new subtype of influenza A virus was described from March 24 through April 24, 2009, in Mexico City, which rapidly spread around the world [2]. Transmission of the 2009 influenza A (H1N1) virus was declared to be a worldwide pandemic by the World Health Organization (WHO) on 11 June 2009 [3]. Influenza virus infections may cause primary influenza viral pneumonia, which can lead to bacterial superinfection and exacerbate underlying chronic illness [4].…”

The most common CXR and CT findings in patients with S-OIV infection were unilateral or bilateral ground-glass opacities with or without associated focal or multifocal areas of consolidation. On MDCT, ground-glass opacities and areas of consolidation had a predominant peribronchovascular and subpleural distribution, resembling organising pneumonia; they progressed to bilateral extensive airspace disease in severely ill patients.

“…On 11 June 2009, the WHO4 5 declared a pandemic of a new strain of the H1N1 virus. In Spain, the Ministry of Health and Social Policy who, together with the social security system manages wage replacement and other benefits during periods of absence from work, implemented several preventive measures,6 7 and announced that people with suspected influenza qualified for short-term sickness absence and should remain at home 8 9.…”

Objectives Workplace absences due to illness can disrupt usual operations and increase costs for businesses. This study of sickness absence due to influenza and influenza-related illness presents a unique opportunity to characterise and measure the impact of the 2009 (H1N1) pandemic, by comparing trends during the pandemic to those of previous years, and adding this information to that obtained by traditional epidemiological surveillance systems. Methods We compared the numbers of cases of sickness absence due to illness caused by influenza and influenza-related illness in 2007e2009, and in the first 3 months of 2010 in Catalonia (n¼811 940) using a time series approach. Trends were examined by economic activity, age and gender. The weekly endemic-epidemic index (EEI) was calculated and its 95% CI obtained with the delta method, with observed and expected cases considered as independent random variables. Results Influenza activity peaked earlier in 2009 and yielded more cases than in previous years. Week 46 (in November 2009) had the highest number of new cases resulting in sickness absence (EEI 20.99; 95% CI 9.44 to 46.69). Women and the 'education, health and other social activities' sector were the most affected. Conclusions Results indicate that the new H1N1 pandemic had a significant impact on business, with shifts in the timing of peak incidence, a doubling in the number of cases, and changes in the distribution of cases by economic activity sector and gender. Traditional epidemiological surveillance systems could benefit from the addition of information based on sickness absence data.
