Publiekssamenvatting Abstract Staat van Infectieziekten in Nederland, State of Infectious Diseases in the Netherlands, 2013 2013 De uitbraak van mazelen in 2013 was de meest in het The measles outbreak in 2013 was the most striking oog springende infectieziekte van dat jaar. Dit blijkt infectious disease of that year. This is demonstrated uit de Staat van Infectieziekten in Nederland 2013, die in the State of Infectious Diseases in the Netherlands inzicht geeft in ontwikkelingen van infectieziekten bij 2013, which provides insight into infectious disease de Nederlandse bevolking. Daarnaast worden de trends in the Dutch population. Developments in ontwikkelingen in het buitenland beschreven die voor other countries that are relevant for the Netherlands Nederland relevant zijn.

Elk jaar komt in de Staat van Infectieziekten een Every year the State of Infectious Diseases publishes thema aan bod; dit jaar is dat de hoeveelheid jaren reports on a particular theme. This year’s topic in goede gezondheid die verloren gaan (ziektelast) concerns the estimation of disease burden: how door infectieziekten. Sommige infectieziekten, zoals many years of healthy life are lost due to infectious maag-darminfecties, komen erg vaak voor maar diseases? Some infectious diseases, such as veroorzaken over het algemeen geen ernstige gastrointestinal infections, occur frequently in the klachten. Andere daarentegen, bijvoorbeeld tetanus, population, but do not generally give rise to serious komen slechts zelden voor maar veroorzaken relatief complaints. In contrast, other diseases, for example veel sterfgevallen. Een gezondheidsmaat die deze tetanus, occur rarely but may lead to a high risk of aspecten van ziekten combineert is de Disability death.

This State of Infectious Diseases in the Netherlands starts with a chapter on the main national and international infectious diseases events that occur- red in the Netherlands in 2013. This chapter includes the table with annual numbers of notified diseases in the Netherlands. One particular topic is highlighted each year. This year the focus is on the burden of infectious disease in the Netherlands. In this report, we present the first comprehensive national burden of disease estimates, for 32 infectious diseases in the period 2007-2011. We computed the disability-adjusted life years (DALY) measure, which combines the burden due to both morbidity and premature mortality associated with all short and long-term consequen- ces of infection. The highest average annual burden was observed for invasive pneumococcal disease (9444 DALYs/year) and influenza (8670 DALYs/year), which represents 16% and 15%, of the total burden of all 32 diseases considered, respectively. Results depend on disease model parameters and assumpti- ons, and on the availability of accurate data on the State of Infectious Diseases in the Netherlands, 2013 | 7 8 | State of Infectious Diseases in the Netherlands, 2013 2 The state of Infectious Diseases in the Netherlands, 2013 2.1 Introduction 2013 and continued into 2014.
