Cat scratch fever, also known as cat scratch disease (CSD), is a bacterial infection caused by Bartonella henselae, which is typically transmitted through scratches or bites from infected cats. While the infection is often mild and self-limiting, it can lead to more severe complications in some individuals, particularly those with weakened immune systems. In this article, we will delve into the world of cat scratch fever, exploring its symptoms, risks, and when it is necessary to seek emergency medical attention.
Understanding Cat Scratch Fever
Cat scratch fever is a relatively common condition, with thousands of cases reported in the United States each year. The bacteria that cause CSD are usually found in the saliva of infected cats, and transmission to humans occurs when an infected cat scratches or bites, introducing the bacteria into the wound. The infection can also be spread through contact with contaminated cat feces or fleas.
Symptoms of Cat Scratch Fever
The symptoms of cat scratch fever can vary in severity and may include:
swollen and painful lymph nodes, particularly in the neck, armpits, or groin
redness and swelling around the site of the scratch or bite
fever, which can range from mild to severe
headache and fatigue
loss of appetite
In most cases, the symptoms of cat scratch fever will resolve on their own within a few weeks without the need for medical treatment. However, in some individuals, the infection can lead to more severe complications, such as:
Complications of Cat Scratch Fever
While rare, cat scratch fever can lead to serious complications, including:
encephalopathy, which is a brain disorder that can cause seizures, confusion, and loss of coordination
osteomyelitis, which is an infection of the bone
endocarditis, which is an infection of the heart valves
neuroretinitis, which is an inflammation of the retina and optic nerve
These complications are more likely to occur in individuals with weakened immune systems, such as those with HIV/AIDS, undergoing chemotherapy, or taking immunosuppressive medications.
