YES! Rat Lungworm Disease should be a reportable disease! This is a major problem. Cases are not reported so the lie that it is rare is perpetuated in the media. It seems like it is not a problem because no one is counting cases and they are not reported. ALL cases should be counted and treated immediately.

New local threat: Rat Lungworm disease, a brain-eating parasitic illness transmitted through snails, slugs and rats
Most recently, Rat lungworm disease has created concern. Rat lungworm disease is a parasitic infection caused by the roundworm that typically affects the brain and spinal cord, often leading to a rare form of meningitis known as eosinophilic meningitis. While many cases resolve on their own, severe infections can cause permanent neurological damage and even death. There is no specific cure for rat lungworm; the parasite eventually dies on its own in the human body, though supportive care is often needed for pain and inflammation.
As of early 2026, no human cases of rat lungworm disease have been reported in San Diego County, however, researchers have confirmed that the parasite (Angiostrongylus cantonensis) is now established in local wildlife. While the risk to the general public is currently low, health officials and researchers from the San Diego Zoo Wildlife Alliance and the CDC recommend preventative care.
The disease was recently confirmed in opossums in seven locations countywide, as well as in rats and a koala at the San Diego Zoo. It can be transmitted through snails, slugs and rats. Residents are advised to carefully wash home-grown produce to avoid consuming slime from slugs or snails, and to control rodents on your property.
The best way to deal with rats is a combination of sanitation, exclusion, and trapping. Immediately remove food sources including trash and pet food; seal entry points with steel wool and snap taps.
