How Fleas Affect Humans

While fleas are not dangerous to humans, their bite can be painful. Their tiny needle mouthparts pierce the skin to drink blood. Fleas also secrete histamine, which causes the affected area to itch and swell. If fleas bite a human, there is a good chance that the bite will lead to a secondary infection.

People have been infected by fleas for thousands of years. In the 14th century, fleas carried the Yersinia pestis bacteria, which caused the black plague. This disease killed 25 million people in Europe and other parts of the world before the invention of antibiotics. Today, there is no vaccine available against the plague, but fleas can still transmit the disease.

The best way to prevent flea infestation in your home is to keep your pets indoors. Fleas often jump from animals to humans, and they can infest your furniture and other areas of your home. Once in your house, fleas can lay eggs, which hatch into adult fleas that bite you.

If the infestation is severe, it can be difficult to get rid of. However, there are several treatments that can help relieve the discomfort. You can use natural remedies or a prescription drug. One of the most common and effective methods is to use an over-the-counter antihistamine cream.
