Symptoms
Symptoms of listeria infection in children can vary depending on the age of the child and the severity of the infection. Some common symptoms include fever, headache, muscle aches, nausea, vomiting, and diarrhea. In more severe cases, the infection can lead to meningitis (inflammation of the lining of the brain and spinal cord) and septicemia (blood infection). Symptoms of meningitis can include a stiff neck, headaches, and confusion. Symptoms of septicemia can include fever, chills, and low blood pressure.
In newborns, symptoms of listeria infection may be more severe and can include fever, vomiting, irritability, and poor feeding. In some cases, the infection can lead to serious complications such as sepsis, meningitis, and even death.
Causes
Listeria infection is caused by the Listeria monocytogenes bacteria. Children can become infected with this bacteria through various means, including:
- Eating contaminated food: Listeria can be found in certain types of raw or undercooked meats, unpasteurized milk and dairy products, and certain types of soft cheeses.
- Drinking contaminated water: Listeria can also be found in soil and water, and can infect children who drink contaminated water.
- Contact with contaminated animals: Children can also become infected with Listeria through contact with animals that carry the bacteria, such as cattle and poultry.
- Mother-to-child transmission: Listeria infection can also be passed from a pregnant woman to her unborn child, either through the placenta or during delivery.
