Leishmaniasis is endemic and mandatorily notifiable in Greece. Epidemiological surveillance data for leishmaniasis in Greece between 1981 and 2011 are presented. In 1998, the notification system began distinguishing between visceral and cutaneous leishmaniasis. The mean annual incidence of reported leishmaniasis cases between 1998 and 2011 was 0.36 per 100,000 population. Of a total 563 leishmaniasis cases reported after 1998, 523 (93%) were visceral leishmaniasis cases. Incidence of reported visceral leishmaniasis cases fluctuated during this period, generally decreasing after 2007, with a small re-increase in 2011. The mean annual incidence rate of reported visceral leishmaniasis cases was significantly higher in less than four year-olds (p <0.001). Leishmaniasis cases occurred both in the country mainland and islands. Between 1998 and 2011, Attica concentrated almost half of the reported visceral leishmaniasis cases, with incidence rates in western Attica and western Athens above 12.00 per 100,000 population. Compared to visceral leishmaniasis, cutaneous leishmaniasis had a rather sporadic distribution, with many prefectures appearing free of cases. From 2004, the notification also included risk factors and of 287 cases with known immune status, 44 (15%) were immunocompromised. Moreover having a dog at home was reported by 209 of 312 leishmaniasis cases (67%), whereas 229 of 307 cases (75%) reported the presence of stray dogs near their residence. Linking clinical surveillance data with laboratory data and improving collaboration with the veterinary public health sector are some of the future challenges for leishmaniasis surveillance in Greece.

Several European countries have timely all-cause mortality monitoring. However, small changes in mortality may not give rise to signals at the national level. Pooling data across countries may overcome this, particularly if changes in mortality occur simultaneously. Additionally, pooling may increase the power of monitoring populations with small numbers of expected deaths, e.g. younger age groups or fertile women. Finally, pooled analyses may reveal patterns of diseases across Europe. We describe a pooled analysis of all-cause mortality across 16 European countries. Two approaches were explored. In the 'summarized' approach, data across countries were summarized and analysed as one overall country. In the 'stratified' approach, heterogeneities between countries were taken into account. Pooling using the 'stratified' approach was the most appropriate as it reflects variations in mortality. Excess mortality was observed in all winter seasons albeit slightly higher in 2008/09 than 2009/10 and 2010/11. In the 2008/09 season, excess mortality was mainly in elderly adults. In 2009/10, when pandemic influenza A(H1N1) dominated, excess mortality was mainly in children. The 2010/11 season reflected a similar pattern, although increased mortality in children came later. These patterns were less clear in analyses based on data from individual countries. We have demonstrated that with stratified pooling we can combine local mortality monitoring systems and enhance monitoring of mortality across Europe.

Between May and September 2011, twenty cases of Plasmodium vivax infection were reported in Greek citizens without reported travel history. The vast majority of those cases were confined to a delimited agricultural area of Evrotas, Lakonia. Conditions favouring locally acquired transmission of malaria, including the presence of competent vectors and migrants from endemic countries exist in Greece, underscoring the need for the development of an integrated preparedness and response plan for malaria prevention.
