An evaluation of data quality in a network for surveillance of Mycobacterium tuberculosis resistance to antituberculosis drugs in Ile-de-France region-2001-2002.

Abstract: We evaluated the French Azay-Mycobacteria network for surveillance of Mycobacterium tuberculosis drug resistance by matching data with those collected through the mandatory notification (MNTB). Sensitivity of Azay was 96% by capture-recapture analysis. Cases reported to MNTB were more often smear-positive than non-reported cases. Concordance of data collected for common cases was excellent for a majority of variables (k > 0.79), excepted for tuberculosis site (k = 0.52). These results suggest a good quality of the network.

Infection par le virus Zika chez la femme enceinte

Abstract: A Zika virus epidemic is currently ongoing in the Americas. This virus is linked to congenital infections with potential severe neurodevelopmental dysfunction. However, incidence of fetal infection and whether this virus is responsible of other fetal complications are still unknown. National and international public health authorities recommend caution and several prevention measures. Declaration of Zika virus infection is now mandatory in France. Given the available knowledge on Zika virus, we suggest here a review of the current recommendations for management of pregnancy in case of suspicious or infection by Zika virus in a pregnant woman.

Reunion, a sentinel territory for influenza surveillance in Europe.

Abstract: In Reunion, a French overseas territory located in the southern hemisphere, increase in influenza activity is generally observed several months earlier than in Europe. Influenza activity is monitored in Reunion through a multi-source surveillance system including sentinel practitioners network, hospital emergency department, laboratory and mortality. Since 2009, three successive influenza epidemics occurred on the island. The largest was observed in 2009 while epidemics in 2010 and 2011 were much weaker. In terms of circulating strains, B viruses were predominant at the beginning of the 2009 epidemic but they were completely evicted once A(H1N1)pdm09 circulation started. In 2010, A(H1N1)pdm09 virus was predominant again, but a constant co-circulation of B viruses was observed. In 2011, A(H3N2) virus circulated. The same viruses were identified a few months later in mainland France in the respective seasons. Since 2009, virus circulation, epidemiological trends and health impact of influenza have been similar to those observed in Europe. Influenza surveillance in Reunion may therefore give reliable early information which should be considered apart from the surveillance in mainland France. Then, it might be even a more suitable predictor for Europe than other temperate southern hemisphere countries. .

2009 pandemic influenza A(H1N1) outbreak in a complex of schools in Paris, France, June 2009.

Abstract: An outbreak of 2009 pandemic influenza A(H1N1), involving 81 cases with symptoms of influenza-like illness, was confirmed in June 2009 in a complex of schools in Paris, France. At that time, there was no community transmission in France. The index case, a 10-year-old girl, had travelled to the United Kingdom with her school class. Of the 81 symptomatic cases, 35 were confirmed and 46 were probable; 48 of the cases were female. Three were adults and 78 were children (median age of the children was 7.9 years, range: 6 months to 12 years). Control measures were implemented as soon as a new case was confirmed in a school, which included active case finding among the pupils in the same class as the index case, setting up a dedicated influenza outpatient clinic that families were recommended to consult if necessary, prophylactic treatment of contacts and school closure. A retrospective study was conducted on all confirmed cases and all symptomatic cases who had consulted the dedicated outpatient clinic from 17 to 27 June 2009. Further work is needed to better define conditions under which the pandemic virus can be transmitted in schools and in households.

Excès de cas humains et animaux de tularémie en France au cours de l’hiver 2007–2008 : émergence ou phénomène isolé ?

Abstract: Resume Contexte La tularemie est une zoonose surveillee en France chez l’homme et chez le lievre. Nous rapportons les resultats de la surveillance de la maladie dans ces deux especes au cours des annees 2007 et 2008. Materiels et methode La tularemie est a declaration obligatoire (DO) chez l’homme depuis 2003. Chez le lievre, la surveillance est volontaire et repose sur le reseau des federations de chasse departementales. Les donnees des DO et de la surveillance volontaire en 2007/2008 ont ete analysees et comparees aux donnees anterieures. Resultats En 2007/2008, 144 cas humains de tularemie et 117 cas chez le lievre ont ete rapportes, soit un doublement par rapport aux annees anterieures. Les cas humains ne differaient de ceux des annees anterieures que par la frequence plus elevee de contact avec des animaux d’elevage et la frequence des cas sans aucune exposition a risque connue. Conclusion Un exces de cas est survenu en 2007/2008 dans les deux especes. Des etudes complementaires sont necessaires afin de determiner l’espece reservoir pour l’homme et le lievre, et ainsi comprendre la survenue de ce pic.
