The Symptoms of Carbon Monoxide Poisoning

Recognising the early symptoms of carbon monoxide poisoning could save your life

Early symptoms of carbon monoxide (CO) poisoning can mimic many common ailments and may easily be confused with food poisoning, viral infections, flu or tiredness. Because carbon monoxide is so difficult for humans to detect, it’s important to stay aware of physical warning signs so you can seek immediate treatment.
