“The risk of dying of CO poisoning while traveling is low compared with, say, the risk of dying in a car accident. But one study suggests that more than 150 CO-related incidents occur in short-term lodging (including hotels and motels) in the US each year and that the number is likely underreported. And the number doesn’t include vacation rentals such as Airbnbs, other travel-related situations, or international incidents.
Even if carbon monoxide poisoning doesn’t result in death, it can still cause lasting health issues. When carbon monoxide replaces oxygen in the bloodstream, it can cause long-term neurological problems — from personality changes to intellectual impairment — even if you appear to have only mild or moderate symptoms up front. And while the risks are higher for children, older adults, and those who are pregnant, people of any age and health status are at risk.
But there’s some good news: CO poisoning is pretty preventable if you have a good-quality carbon monoxide detector. When you’re on the road, a small, lightweight, battery-operated detector could save your life.”
