Incidence of notified Lyme borreliosis in Germany, 2013–2017

Scientific Reports (2018)

Julia Enkelmann Merle M. Böhmer Volker Fingerle C Siffczyk Dirk Werber

Lyme borreliosis (LB) is the most commonly reported tick-borne disease in Germany. In 9/16 states, notification of erythema migrans (EM), acute neuroborreliosis (NB) and Lyme arthritis (LA) is mandatory. We describe incidence measures, time trends, geographical distribution and frequencies of manifestations to better understand LB epidemiology and target prevention measures. We used cases notified in the 9 states and confirmed by local health offices, 2013-2017, to calculate incidences by time, place and person. Altogether, we observed 56,446 cases. Disease onset peaked yearly in July. Incidence ranged from 26/100,000 (2015) to 41/100,000 (2013) with mean annual incidences 2013-2017 on district level between 0.5/100,000 and 138/100,000. Median age was 54 years with peaks in boys (5-9 years, mean incidence 36/100,000) and women (50-69 years, mean incidence 57/100,000). 95% experienced EM only, 2.7% NB and 2.1% LA. 54% were female, but more men had NB (56%) and LA (53%, p < 0.001). Hospitalisation was recorded for 10% of LA and 71% of NB cases. LB remains an important public health concern in Germany with marked regional variation. To facilitate early diagnosis and treatment, health authorities should raise awareness among physicians and promote prevention strategies among the general population: tick-bite-protection, prompt tick removal and medical consultation.

by laboratory contamination with Asian genotype I.Possible introduction and detection of Asian DENV-4 strains in Brazil should not be ignored because the possibility of multiple introduction events in the country resulting from intense transit of people and commercial activities across Brazil from the Caribbean and Asian regions poses a real risk.However, at this time, only genotype II has been isolated and genetically characterized (1).The previously published articles lack strong and reliable scientifi c evidence.

EHEC O104:H4 outbreak 2011 in Europe: a new tool to support the outbreak investigations on governmental side

Armin A. Weiser Susan Gross Anika Schielke Jan-Frederik Wigger A. Emert

Traceability of food supply on the basis of disease clusters (= places with known exposures + indisposition by people, e.g. hotels, restaurants, etc.) combined with epidemiological analysis is the method of choice in outbreak situations, particularly when the bacteriological proof of the agent in the incriminated food is lacking. The critical point is to collect and organize data about the supply chains. The method developed here is based on Excel templates for data suppliers (e.g. companies, state agencies, local veterinary offices). To compensate the disadvantages of Excel-based data exchange (manual data entry is very time consuming and error-prone), a new database infrastructure was developed, providing automatic support for data correction. In the EHEC outbreak in 2011, the newly developed system has proved to be very effective. It is applicable to all types of food, easy to handle in outbreak investigationsand also allows for a combined forward- and backward-tracing. For significant improvement of the tracing process, the development of a data management system is required, that allows for rapid deployment of electronic data delivery, while ensuring the confidentiality of the data.

A combined case-control and molecular source attribution study of human Campylobacter infections in Germany, 2011–2014

Scientific Reports (2017)

Bettina Rosner Anika Schielke Xavier Didelot Friederike Kops Janina Breidenbach

Campylobacter infection is the most commonly notified bacterial enteritis in Germany. We performed a large combined case-control and source attribution study (Nov 2011-Feb 2014) to identify risk factors for sporadic intestinal Campylobacter infections and to determine the relative importance of various animal sources for human infections in Germany. We conducted multivariable logistic regression analysis to identify risk factors. Source attribution analysis was performed using the asymmetric island model based on MLST data of human and animal/food isolates. As animal sources we considered chicken, pig, pet dog or cat, cattle, and poultry other than chicken. Consumption of chicken meat and eating out were the most important risk factors for Campylobacter infections. Additional risk factors were preparation of poultry meat in the household; preparation of uncooked food and raw meat at the same time; contact with poultry animals; and the use of gastric acid inhibitors. The mean probability of human C. jejuni isolates to originate from chickens was highest (74%), whereas pigs were a negligible source for C. jejuni infections. Human C. coli isolates were likely to originate from chickens (56%) or from pigs (32%). Efforts need to be intensified along the food chain to reduce Campylobacter load, especially on chicken meat.
