Measles
Several cases of measles have been reported to Clark County Public Health since July 22, 2026. The most recent case was announced Aug. 11, 2026, and is a Clark County child who is unvaccinated.
The person who tested positive for measles visited a local health care facility while contagious. People who were at the facility and have not been vaccinated against measles or have not had measles in the past are at risk for getting sick.
Visit the measles investigation webpage for more information.
Water quality monitoring at local lakes
Before visiting a local lake, be sure to check for water quality advisories. Public Health monitors water quality at designated swim beaches and other waterbodies throughout the summer to determine if the water is safe for swimming and recreation.
Public Health collects water samples from Vancouver Lake, Klineline Pond and Battle Ground Lake to test for bacteria that can make people sick. Public Health also monitors the swim beaches and other local lakes, including Round Lake and Lacamas Lake, for harmful algal blooms. The algal blooms can release toxins that can make people sick and deadly for dogs.
Public Health issues advisories if waterbodies are unsafe for swimming and recreation. Visit the Current Advisories webpage for the latest information.

Heat safety
When temperatures rise, it’s important to take precautions to prevent heat-related illnesses, like heat exhaustion or heat stroke.
Heat-related illness can occur in anyone, including young and healthy people. Older people, babies and young children, people with chronic illnesses and people who are pregnant are at higher risk of developing heat-related illness.
Visit Public Health’s Hot weather safety webpage to learn about the signs of heat illness, how to prevent heat illness and tips for staying cool if you don't have air conditioning at home.
Childhood vaccines
Childhood vaccinations keep children healthy, prevent serious illnesses and hospitalizations, and save lives. Ensuring your child is up to date on their vaccines can help to prevent missed school days this fall and winter.
Experts at the American Academy of Pediatrics and the Washington State Department of Health make childhood vaccine recommendations based on decades of research showing vaccines are safe and effective.

Bat season is here
Bats are the primary animal that carries rabies in Washington. During the spring and summer, when they’re most active, people may be more likely to find one in their living spaces.
Never touch a bat with bare hands and teach children to never touch them. People who think they may have been bitten, scratched, or had direct contact with a bat should make sure they’re no longer in the same space as the bat. If possible, close the doors and windows to the room where the bat is located. Then call Clark County Public Health.
Visit the Animal bites and rabies webpage to learn more.
