Secular trends in incidence of acute gastroenteritis in general practice, France, 1991 to 2015.

We analysed 25 years of general practitioner (GP) visits for acute gastroenteritis (AG) surveillance in France, by the GP Sentinelles network. We searched for time trends of acute gastroenteritis incidence during winter periods. Data from emergency departments and drug reimbursement were additional data sources.

Undiagnosed HIV prevalence based on nontargeted screening in emergency departments.

To estimate the 2009-2010 undiagnosed HIV prevalence in the Paris metropolitan region, where half of France's new HIV cases are diagnosed annually, we used a direct method based on a large sample of emergency department patients unaware of their HIV status. The overall expected prevalence was 0.09% (95% confidence interval 0.

Modest public health impact of nontargeted human immunodeficiency virus screening in 29 emergency departments.

Background: To lower the number of undiagnosed infections and to improve early detection, international health agencies have promoted nontargeted human immunodeficiency virus (HIV) screening in health care settings, including emergency departments (EDs). This strategy remains controversial and has yet to be tested on a large scale. We assessed the public health impact of nontargeted HIV-rapid test (RT) screening among ED patients in the metropolitan area of Paris (11.

Population-based HIV-1 incidence in France, 2003-08: a modelling analysis.

Background: Routine national incidence testing with enzyme immunoassay for recent HIV-1 infections (EIA-RI) has been done in France since January, 2003. From the reported number of HIV infections diagnosed as recent, and accounting for testing patterns and under-reporting, we aimed to estimate the incidence of HIV infection in France in 2003-08.

Methods: We analysed reports from the French National Institute for Public Health Surveillance for patients who were newly diagnosed with HIV between January, 2003, and December, 2008.

Hepatitis C virus genotype 3 and the risk of severe liver disease in a large population of drug users in France.

Although risk factors for cirrhosis in chronic hepatitis C virus (HCV) infection have been identified, the role of HCV-genotype 3 remains controversial, and limited data are available in drug users. The aim of the study was to assess risk factors for severe liver disease (cirrhosis/hepatocellular carcinoma) in HCV-infected drug users between 2001 and 2007 in France. Patients who reported drug use and who had been referred for HCV infection to hepatology centers from a national surveillance system were identified.

Risk factors for acquiring sporadic Campylobacter infection in France: results from a national case-control study.

Background: To better document the risk factors for sporadic Campylobacter infection in France, we conducted a national case-control study from September 2002 to June 2004.

Methods: Cases with confirmed Campylobacter infection were sampled through the national surveillance laboratory network. Cases and controls who were matched for age, as well as attending physicians, were interviewed about foods consumed, food preparation practices, travel history, contact with cases and animals during the 8 days before the onset of infection, and any antibiotic use occurring during the 30 days before onset.
