Symptoms
Small, raised bumps
Intense itching, especially around the bite site
Redness or inflammation around the bite
Hives or a rash in some individuals
Bites often appear in clusters or lines, typically on the ankles, legs, or waist
In rare cases, an allergic reaction with symptoms like difficulty breathing or swelling
Causes
Flea bites are caused by fleas feeding on human blood. Fleas are typically brought into the home by pets (cats and dogs are the most common carriers), but they can also be carried by other animals like rodents. Fleas jump onto a host and bite the skin to consume blood.
Medicine Used
Topical Corticosteroid Creams: Reduce inflammation and itching (e.g., hydrocortisone cream).
Antihistamine Creams or Oral Medications: Help relieve itching (e.g., diphenhydramine, loratadine).
Calamine Lotion: Soothes the skin and reduces itching.
Antibiotics: Prescribed by a doctor if secondary bacterial infection develops from scratching.
Is Communicable
Flea bites themselves are not communicable from person to person. You cannot "catch" flea bites from someone who has them. However, fleas can jump from person to person if they are present in the environment.
Precautions
Treat Pets: Regularly treat pets with flea prevention medication as prescribed by a veterinarian.
Vacuum Thoroughly: Vacuum carpets, rugs, upholstery, and pet bedding frequently.
Wash Bedding: Wash pet bedding and your own bedding in hot water.
Yard Treatment: Treat your yard with insecticides if fleas are present outdoors.
Insect Repellent: Use insect repellent containing DEET on yourself when in areas where fleas are likely to be present.
Avoid Contact: Try to avoid contact with areas heavily infested with fleas.
How long does an outbreak last?
The duration of a flea bite outbreak depends on how quickly the flea infestation is controlled. If the source of the fleas (e.g., pets, home environment) is not treated, the bites will continue to occur. Once the infestation is addressed, new bites should cease. The existing bites will take a few days to a week or two to heal depending on individual reactions and treatments.
How is it diagnosed?
Flea bites are typically diagnosed based on:
Visual Examination: The appearance of the bites themselves (small, itchy, clustered bumps).
History: Recent exposure to pets or environments where fleas might be present.
Physical Findings: Finding fleas on pets or in the home environment.
A doctor is not always needed for diagnosis unless complications occur.
Timeline of Symptoms
Immediately: Flea bites occur. A small prick may be felt.
Minutes to Hours: Itching and small red bumps appear.
1-2 Days: Itching intensifies; bumps may become more inflamed.
Days to Weeks: Symptoms gradually subside with treatment and control of the flea infestation. Untreated bites can persist and itch for several weeks.
Important Considerations
Secondary Infections: Avoid scratching flea bites excessively, as this can lead to secondary bacterial infections.
Allergic Reactions: Be aware of potential allergic reactions, especially if you have a history of allergies. Seek medical attention if you experience difficulty breathing, swelling, or other severe symptoms.
Flea Control is Key: The most important step is to eliminate the fleas from your home and pets to prevent further bites. Coordinate treatment between your pets, your home, and your yard to maximize effectiveness.
Rare Diseases: In rare cases, fleas can transmit diseases such as typhus and plague. If you develop fever, headache, or other unusual symptoms after being bitten by fleas, seek medical attention immediately.
