Recorded cases of dogs infected with Lepto disease.
The Animal and Plant Health Agency (APHA) is a DEFRA Agency. It is responsible for gathering data on animals infected with disease.
APHA produce quarterly and yearly reports on Non statutory zoonoses diseases.

The following figures are for Great Britain, that is to say England, Scotland and Wales.
Northern Ireland has their own laboratory and records.
By definition, these figures are only of infected dogs reported to APHA or where APHA has received a sample for an animal due to be exported. There will be others that have not been reported to APHA as the veterinary practice used a different laboratory, or the vet didn't diagnose the sick dog as having Lepto.
During 2019, the results for L. Canicola and L. Icterohaemorragiae for dogs being exported were separated from samples submitted for diagnosis. Hence the chart for 2020 onwards having a slightly diferent layout.
These tables have been created from the figures provided in APHA's FZ2100 reports since 2010.
It is unknown as to how many cases of dogs infected with Lepto are not reported to APHA. Also of how many Lepto infected dogs are not detected as being infected with Lepto, but the individual identified symptoms are treated as separate issues.
