Health officer briefs board: hantavirus and Ebola unlikely locally; measles risk growing in Washington

Clallam County’s health officer updated the Board of Health on May 19 about several infections in the news and implications for local residents.

The health officer said a strain of hantavirus associated with a recent cruise-ship cluster is of low risk to county residents because transmission typically requires contact with rodent droppings; nonetheless she advised precautions such as wetting dusty areas and wearing N95 respirators when cleaning barns or cabins. She noted this hantavirus can, in rare circumstances, transmit person-to-person in very close quarters.

On Ebola, the officer described large, worsening outbreaks in the Democratic Republic of Congo and Uganda and said transmission is typically caregiver-to-patient and requires close contact with bodily fluids. She said Ebola is very unlikely to appear in Clallam County but urged awareness because of outbreak severity in affected countries.

The officer singled out measles as the more plausible local concern: she reported 44 confirmed cases in Washington state and said community transmission has been detected, making it more likely measles could appear locally. The county encouraged residents to verify vaccination status or immunity via a titer and to vaccinate eligible children; she reminded the board that routine childhood vaccination schedules generally begin at age 1 (with early dosing at 6 months for travel to high-transmission areas).

A separate report noted one pertussis case likely acquired out of state; the family isolated and received appropriate care with no evidence of a local outbreak at this time.

Board members asked clarifying questions about disease-investigation counts and trends; staff said increases in some disease investigations reflect more testing and recognition rather than true prevalence increases in all cases, and that improved outreach and screening are partly responsible for higher identified totals.
