The Oregon Health Authority warned Saturday that wildfire smoke can exacerbate respiratory diseases, including COVID-19.

That poses a problem in parts of Southern Oregon, according to the Oregon Smoke Information website, maintained by a consortium of agencies that track air quality.

As of Saturday afternoon, smoke was leading to unhealthy air quality in Klamath Falls and Lakeview, according to the site, which said the air is unhealthy for sensitive groups near Burns in Eastern Oregon. The Oregon Smoke Information website also flagged moderate levels of air contamination in Central Oregon, which has been affected by smoke from fires on the Warm Springs Reservation.

The Oregon Health Authority also reported 190 new COVID-19 diagnoses, bringing confirmed and presumptive cases in the state to 28,044 since the start of the pandemic.

State health officials plan to take Labor Day off from releasing some COVID-19 information, and will be back with full updates on Tuesday, the Oregon Health Authority said in an email.

Bend officials ask tourists to stay home

Bend leaders are again asking tourists to stay away, and asking lodgings not to book short-term accommodations, as the Central Oregon city seeks to slow the spread of COVID-19 so in-person schooling can resume.

City leaders issued their initial non-binding administrative order in July, and it was set to expire on Labor Day. The new order is now in effect through Oct. 26 — the point at which the Bend-La Pine School District could consider some version of hybrid or in-class learning.
