Infant botulism is a rare but serious illness that affects babies, usually under one year old. It occurs when infants ingest spores of the Clostridium botulinum bacteria, which can grow in their intestines and produce toxins. Common sources of these spores include honey and certain foods that are not properly processed. Symptoms of infant botulism may include constipation, weak muscles, and difficulty feeding. If left untreated, the condition can lead to severe complications, including respiratory failure. Early diagnosis and treatment are crucial, and most infants recover with appropriate medical care.
