In 2022, the first and second most reported zoonoses in humans were campylobacteriosis and salmonellosis, respectively. The number of cases of campylobacteriosis and salmonellosis remained stable in comparison with 2021.
Campylobacteriosis and salmonellosis were the most frequently reported zoonotic diseases in humans in the EU in 2022. For West Nile virus, an increase of the number of infections was observed.
A joint study of the National Public Health Organization in Greece (NPHO) and the European Centre for Disease Prevention and Control (ECDC) conducted in 15 Greek hospitals in 2022 sheds light on the rapid spread of carbapenemase-producing, highly drug-resistant Klebsiella pneumoniae sequence type (ST) 39, following its initial documentation in a European-wide genomic survey in 2019.
The main aim of the genomic study described in this surveillance report was to determine the distribution of the highly drug-resistant clade of Klebsiella pneumoniae (sequence type (ST) 39 in Greek hospitals in 2022.
Prevalence data from sources such as population surveys can be a useful complement to case based surveillance data for hepatitis C. Case-based surveillance has limitations as most diagnosed cases are chronic in nature and detection of cases depends largely on testing practices. Prevalence data can therefore contribute towards a fuller understanding of the epidemiology of hepatitis C.
