New Legionnaires’ disease case discovered months after North Portland outbreak

An article posted on Friday 19th March by details a new case of legionnaires disease breaking out in North Portland months after a previous outbreak.

Months after an outbreak of Legionnaires’ disease in North Portland, Multnomah County says it was informed of a new case earlier this week.

Back in January, one person died and three more people were hospitalised after an outbreak of the disease at Rosemont Court apartments. In that instance, the county offered temporary housing for residents and evacuated more than 100 people.

This time, they are not recommending anyone evacuate, but public health says it is investigating to find a source.

Multnomah County health officials say that it is not uncommon for a new Legionnaires’ disease case to occur soon after an initial outbreak. They say this is because the Legionella bacteria that causes it grows in pipes under a biofilm, and it’s difficult to eradicate all at once.

Public health is recommending routine water management and treatment.

The county says Communicable Disease Services is screening all residents for symptoms and communicating how to mitigate the risk of infection.
