Symptoms
The most common symptom of flea infestation in children is itching and skin irritation. This can be caused by the flea's saliva, which contains anticoagulants that prevent blood from clotting. The itching can be severe and can lead to scratching, which can further irritate the skin and cause infection. In severe cases, flea bites can cause anemia, especially in young children. Anemia is a condition in which there is a deficiency of red blood cells or hemoglobin in the blood, which can cause fatigue, weakness, and pallor.
Causes
Fleas are commonly found on pets, such as dogs and cats. They can also be found on other animals, such as rats and squirrels. Fleas can jump from one host to another, so children can become infested with fleas if they come into contact with an infested pet or animal. Fleas can also be found in outdoor areas, such as parks and playgrounds, where children are likely to play.
