LEPTOSPIROSIS: PUBLIC HEALTH ASPECTS
The leptospires which infect dogs and cats can also infect and cause severe, sometimes
fatal disease (Weil's disease) in man. The zoonotic potential of the infection must
always be kept in mind if leptospirosis is suspected in a dog or cat.
However, dogs (and, presumably, cats) are relatively rare sources of human infection
nowadays. The most frequent sources of human infection are rat infested environments
- there is a relatively high risk of infection amongst those taking part in water
sports - and cattle.
