Is there a dog disease outbreak in Oregon right now?

ParvoMaps is currently tracking 6 active reports in Oregon, most commonly blue-green algae. Reports stay marked active for a set window per disease, then move to historical.

What dog diseases have been reported in Oregon?

Reports in Oregon cover blue-green algae, rabies, parvovirus, drawn from news coverage, health department notices and community reports.

How do I know if a report near me is still current?

Every report carries the date it happened and a link to its source. Each disease has its own active window — blue-green algae advisories expire in 30 days, parvo reports stay active for a year — so a pin marked active is one still worth acting on.
