Oregon health Q&A: How many measles cases do we have in the state?

Questions are answered by experts at the Oregon Health Authority, other state agencies or community partners. Questions and answers are republished by permission.

Q:

Is there still only one measles case [in Oregon]?

– Bob, Corvallis

A:

Yes, still just the one case, confirmed June 19. With no known spread one month later, we are crossing our fingers that it was an isolated case. We continue to advise people with a rash or other measles-like

symptoms

to contact their provider and arrange to be evaluated in a place where they will not expose other people. We also continue to advise providers to consider measles as a possible diagnosis, and to test for it when appropriate.

We will of course alert the public if there are additional cases, and you can also follow our online

Weekly Communicable Disease Report

, selecting measles from the drop down menu, to stay up to date.

Nationally, the measles outbreak of 2025 has slowed down. As of July 15, CDC reports

1,309 confirmed cases in 39 states

. Of that, 13% has been hospitalized, and three people have died – an adult in New Mexico and two children in Texas.

Q:

What is the water quality in Emigrant Lake in Ashland, Oregon?

– Peg, Ashland

A:

The latest testing data show the water quality in Emigrant Lake is safe. We had issued an advisory there in early May, which was

lifted May 9

. The advisory was issued after partners confirmed that photo and satellite imagery showed potentially harmful algae blooms near popular recreation sites. Follow-up testing showed that cyanotoxins were below harmful levels for recreational use, which allowed the advisory to be lifted.

In addition,

Rogue Riverkeeper

conducts and reports bi-weekly testing for e. coli bacteria in several rivers and lakes throughout the Rogue Basin, including Emigrant Lake, where the most recent samples were

taken July 14

Rogue Riverkeepers submits its water quality and safety information to “

Swim Guide

”—a national tool which you can use to look for safety information submitted by participating affiliates throughout Oregon and beyond.

Oregon is also one of the few states that have

rules

requiring public water systems to routinely monitor for cyanotoxins, and because Emigrant Lake supplies drinking water to a

county park

, Jackson County tests Emigrant Lake’s water

every two weeks

between May 1 and Oct. 31 before it enters the drinking water treatment plant.

People can search for local drinking water testing results in their neighborhood using

this interactive map.

We like to remind people that regardless of the most recent testing, water conditions can change quickly so it’s important to recognize the

signs of a bloom

. People should stay out of the water, and keep their pets out of the water, if the water looks foamy, scummy, like spilled paint, green, blue-green, pea-green, brownish red, or where green globs can be seen in the water, or where mats are growing on rocks or sand or accumulating along the shore.

We encourage people to

report blooms

or related

human

animal

illnesses directly to OHA using forms found on

our website
