What Is Cat Scratch Fever?

Cat scratch fever, also called cat scratch disease, is caused by the Bartonella henselae bacteria. It spreads mainly through scratches, bites, or licks from infected cats. Usually, the infection is mild but can cause more serious issues in people with weak immune systems.

The disease often starts with a small bump or blister at the scratch site. It can then progress to swollen lymph nodes and flu-like symptoms. Knowing what to expect helps you recognize the infection early and seek medical advice.

• Cat scratch fever is caused by Bartonella henselae bacteria carried by cats, especially kittens who are more likely to carry the bacteria.

• The bacteria enter the body through broken skin, usually from a cat scratch or bite, making wounds a key infection route.

• Symptoms typically appear within 3 to 14 days after exposure, so early signs can be subtle but important to notice.

• Most healthy people recover without complications, but those with weakened immune systems may face more serious health risks.

Understanding the cause and how it spreads is the first step to recognizing and preventing cat scratch fever. Always handle cats gently and care for any scratches promptly.

Common Symptoms of Cat Scratch Fever

Symptoms vary but often start near the site of the scratch or bite. You might notice a small bump or blister that looks like a pimple. This is usually followed by swollen lymph nodes near the affected area.

Other symptoms can mimic a mild flu, including fever, fatigue, headache, and loss of appetite. These signs can last for several weeks, so it’s important to monitor your health closely after a cat scratch.

• A small red bump or blister at the scratch site usually appears within a week, signaling the start of infection.

• Swollen and tender lymph nodes near the scratch, such as in the armpit or neck, often develop within two weeks.

• Flu-like symptoms like mild fever, fatigue, headache, and body aches can last for several weeks, indicating systemic infection.

• In rare cases, complications like eye infections or neurological symptoms may occur, especially in people with weakened immunity.

Recognizing these symptoms early allows you to seek medical care promptly. If you notice unusual swelling or persistent fever after a cat scratch, consult your healthcare provider.

How Is Cat Scratch Fever Diagnosed?

Doctors diagnose cat scratch fever based on your symptoms, history of cat exposure, and physical exam. They may order blood tests to detect antibodies or the bacteria itself. Sometimes imaging tests are needed if lymph nodes are very swollen.

Because symptoms can resemble other illnesses, accurate diagnosis is important. Your doctor will consider your recent contact with cats and the timing of symptoms to confirm the infection.

• Medical history focusing on recent cat scratches or bites helps doctors link symptoms to possible cat scratch fever infection.

• Physical examination checks for swollen lymph nodes and skin lesions typical of the disease.

• Blood tests can detect antibodies against Bartonella henselae, confirming exposure to the bacteria.

• In some cases, lymph node biopsy or imaging like ultrasound may be used to rule out other causes of swelling.

Early diagnosis leads to better treatment outcomes. If you suspect cat scratch fever, be honest about your cat contact and symptoms during your medical visit.

Treatment Options for Cat Scratch Fever

Most cases of cat scratch fever resolve without treatment, but antibiotics can speed recovery and reduce symptoms. Your doctor will decide if medication is necessary based on your symptoms and health status.

In addition to antibiotics, supportive care like rest, pain relief, and wound cleaning helps manage the infection. Severe cases may require more intensive treatment or monitoring.

• Antibiotics such as azithromycin are commonly prescribed to reduce bacterial infection and speed healing.

• Cleaning cat scratches promptly with soap and water lowers the risk of infection and helps prevent complications.

• Pain relievers like acetaminophen or ibuprofen can ease fever and swollen lymph node discomfort.

• Severe or persistent cases may require longer antibiotic courses or specialist care, especially for people with weakened immune systems.

Following your doctor’s instructions and completing the full antibiotic course is key to fully clearing the infection. Avoid scratching or irritating wounds to promote healing.

Preventing Cat Scratch Fever

Prevention focuses on reducing your risk of scratches and bites from cats. Proper cat handling and hygiene are essential. Educating yourself and family members about safe cat interactions can prevent infection.

Regular veterinary care for your cat also helps reduce the chance they carry the bacteria. Keeping your cat indoors and flea-free lowers the risk of transmission.

• Handle cats gently and avoid rough play that can lead to scratches or bites, especially with kittens who are more likely to scratch.

• Wash any cat scratches or bites immediately with soap and water to reduce bacteria entering your skin.

• Keep cats indoors and use flea control treatments to minimize Bartonella bacteria spread by fleas.

• Teach children to respect cats and avoid provoking them, as children are at higher risk for cat scratch fever.

By following these prevention tips, you can enjoy your cat’s company safely and reduce the chance of infection. Regular vet visits keep your cat healthy and less likely to carry harmful bacteria.

When to See a Doctor

If you develop symptoms like swollen lymph nodes, fever, or persistent fatigue after a cat scratch, it’s important to see a healthcare provider. Early medical evaluation helps prevent complications and ensures proper treatment.

People with weakened immune systems should be especially cautious and seek prompt care if exposed to cat scratches or bites. Timely diagnosis and treatment improve recovery chances.

• Seek medical attention if you notice enlarged, painful lymph nodes near a recent cat scratch or bite, as this is a common sign of infection.

• Persistent fever, headache, or fatigue following cat exposure warrants a doctor’s evaluation to rule out cat scratch fever or other infections.

• People with weakened immune systems, such as those with HIV or on immunosuppressive drugs, should see a doctor immediately after cat scratches.

• If wounds from cat scratches become red, swollen, or produce pus, prompt medical care is necessary to prevent serious infections.

Don’t delay seeking care if symptoms worsen or don’t improve. Early treatment reduces the risk of complications and helps you recover faster.

Conclusion

Cat scratch fever is a common infection caused by bacteria transmitted through cat scratches or bites. Knowing the symptoms and how to recognize them early is vital for timely treatment. Most people recover well with proper care.

Preventing cat scratch fever involves safe cat handling, prompt wound cleaning, and regular veterinary care for your pet. If you suspect you have cat scratch fever, consult your healthcare provider for diagnosis and treatment to ensure a smooth recovery.
