Infectious Diseases 2019

Germany: Infectious disease epidemiology - Annual Report, 2018

10 August, 2019

As in the previous year, the gastrointestinal diseases norovirus gastroenteritis, Campylobacter enteritis and rotavirus gastroenteritis and the vaccine-preventable diseases influenza and chicken-pox were the five most commonly reported notifiable diseases. In 2018, a total of 67,872 Campylobacter infections were recorded, which was 2 percent lower than the year before. 
In 2018, 13,529 salmonellosis infections were recorded. It was the second most notifiable bacterial gastrointestinal disease after Campylobacter. The number of illnesses fell by 5.2 percent compared to 2017 but was still higher than in 2016. As in previous years, the highest age-specific incidences were in children younger than five years old. 
When data on serovar was known, S. Enteritidis and S. Typhimurium were the most often recorded by far from S. Infantis, S. Derby and S. Kentucky. Compared to the previous year, the number of S. Enteritidis and S. Typhimurium decreased. Molecular surveillance plays an increasingly important role in the detection of outbreaks. One of the largest outbreaks in 2018 included 191 cases in several federal states and was caused by Salmonella enteritidis complex type (CT) 1734. The probable vehicle of infection were barn eggs. During this outbreak, the results of molecular typing of pathogen isolates were used to discover the association with 24 smaller outbreaks.
