A study conducted by the Robert Koch Institute in Germany determined a sharp reduction in a wide range of foodborne infections during 2020. This was attributed to reduced social activity, restrictions on dining out, closing of schools, universities and daycare facilities due to COVID.
The study considered 32 infectious and parasitic conditions noting declines in excess of 80 percent for rotavirus and Shigella infections and approximately 50 percent for E.coli and Salmonella, and a one third reduction in Campylobacter infections.
