Epidemiology of CO poisoning

Carbon monoxide (CO) poisoning occurs when this odorless, tasteless gas from sources like faulty furnaces or car exhaust builds up indoors, preventing oxygen from reaching body tissues. It can happen anytime but is more common during winter or in poorly ventilated areas. Symptoms range from headache and dizziness to confusion and loss of consciousness. Severe cases can cause brain damage or death. Prompt detection with CO detectors and proper maintenance of fuel-burning appliances are key to prevention. Awareness and early recognition are essential for avoiding serious health consequences.
