Are There Any Long-term Health Effects Associated With Flea Or Lice Infestations?

Flea and lice infestations can cause a range of health effects, but most of them are short-term and can be resolved once the infestation is treated. However, if left untreated for an extended period of time, there are some potential long-term health effects that can occur.

Flea infestations can cause allergic reactions in some people, which can result in ongoing skin irritation and itching. Scratching the bites can lead to open wounds that are vulnerable to infection. In rare cases, fleas can transmit diseases such as typhus and plague, although this is more common in areas where these diseases are endemic.

Lice infestations can also cause ongoing itching and skin irritation, which can lead to open wounds and secondary infections. In addition, severe infestations can lead to anemia, as lice feed on blood. This is more common in children and individuals with weakened immune systems.

In both cases, the psychological effects of an infestation can be long-lasting. The stress and anxiety associated with an infestation can lead to sleep disturbances, depression, and other mental health
