" In a recent issue of Eurosurveillance, Gautret et al. report two cases of dengue fever in travellers returning from Benin.
The authors noted that serology tests indicated the presence of anti-dengue virus (DENV) IgM and IgG antibodies in serum samples obtained from the travellers from Benin, where limited data are available on dengue outbreaks."

The influenza A(H5N1) epidemic at six and a half years: 500 notified human cases and more to come
A study published at Eurosurveillance, Volume 15, Issue 29, 22 July 2010, exceprt from a long but informative article :
" Since November 2003, the epidemic intelligence team at the French Institut de Veille Sanitaire has been gathering data on influenza A(H5N1) circulation in poultry and on human cases worldwide. As Indonesia notifies the world’s 500th case to the World Health Organization, we discuss the epidemiological situation and trends of A(H5N1) influenza. Although the overall number of cases reported worldwide has decreased, influenza A(H5N1) continues to circulate intensely in some countries and more cases are to be expected, especially in Egypt and Indonesia.
The international and tropical department of the Institut de Veille Sanitaire (InVS) conducts constant monitoring of health events worldwide to provide French health authorities with timely forewarning of public health events of international concern. This process, known as epidemic intelligence (EI), has been described elsewhere [1]. Although topics vary widely, the situation of highly pathogenic influenza A(H5N1) influenza in the world has constantly been monitored since 2003. This paper describes the epidemiological situation six and a half years into the epidemic, as Indonesian authorities notify the world’s 500th case since November 2003 [2].
Epizootic
From the end of 2003 to 1 July 2010, 63 countries or territories on the Asian, African or European continents (incl. 15 European Union countries) have notified infections by influenza A(H5N1) virus in poultry or wild birds to the World Organization for Animal Health (OIE) [3]. In 2009, a total of nine countries notified outbreaks in poultry or were considered enzootic by OIE: Bangladesh, Cambodia, China (Tibet and Xinjiang), Egypt, India, Indonesia, Laos, Nepal (first notification) and Vietnam."

2009 pandemic influenza A(H1N1) virus in Scotland: geographically variable immunity in Spring 2010, following the winter outbreak
A report from Eurosurveillance, please read the long but very informative study, excerpt :
" We determined the age- and location-specific seroprevalence of antibodies against 2009 pandemic influenza A(H1N1) virus in Scotland following the first two waves of infection. Serum samples collected following the winter outbreak were analysed by microneutralisation assay. The proportion of positive sera varied significantly between cities and, in the case of Inverness, between age groups (with younger adults more likely to be positive than older individuals). This study demonstrates that older people are no longer more likely to have antibodies against the virus than younger adults.
The pandemic influenza A(H1N1) virus has been spreading throughout the world since May 2009. The objective of this study was to determine the age- and location-specific seroprevalence of antibodies against 2009 pandemic influenza A(H1N1) virus in Scotland following the first two waves of the pandemic. Although population demographics and contact patterns will vary between countries, this information will assist European public health policy makers in planning for the 2010-11 influenza season."
