Recently reported cases of the often fatal bacterial infection leptospirosis in dogs in Sydney have raised the issue of animal diseases that also affect humans.

This zoonotic disease is spread by rats and other rodents. However, this latest cluster in dogs has not been accompanied by human cases in the Sydney area so far; dog cases aren’t always accompanied by human cases nearby.

So what is leptospirosis? And what can we do to protect ourselves and our pets from this potentially fatal disease?

There have been at least six confirmed cases of canine leptospirosis so far in Sydney’s inner west and city in 2019, with three in May and June. Five of the six dogs died.
