What is Cat Scratch Fever and how do humans get infected?
Cat Scratch Fever, also known as Cat Scratch Disease (CSD), is a bacterial infection caused by Bartonella henselae. It is typically transmitted to humans through scratches or bites from infected cats, usually kittens. The bacteria can also be transmitted through contact with infected cat saliva or other bodily fluids. When an infected cat scratches or bites a human, the bacteria can enter the body through the wound, leading to infection. It’s essential to note that not all cats carry the bacteria, and the risk of transmission can be reduced by taking precautions such as washing hands after handling cats and avoiding rough play.
In most cases, Cat Scratch Fever is a self-limiting disease, meaning it will resolve on its own with rest and supportive care. However, in some cases, the infection can lead to more severe complications, such as swollen lymph nodes, fever, and fatigue. If left untreated, the infection can also spread to other parts of the body, including the brain, eyes, and bones. It’s crucial to seek medical attention if symptoms persist or worsen over time. A healthcare professional can diagnose CSD through a physical examination, medical history, and laboratory tests, such as blood tests or imaging studies. Prompt treatment can help alleviate symptoms, reduce the risk of complications, and prevent long-term health consequences.
What are the common symptoms of Cat Scratch Fever in humans?
The common symptoms of Cat Scratch Fever in humans typically develop within 3-10 days after exposure to the bacteria. The primary symptom is a scratch or puncture wound, which may become red, swollen, and painful. Additionally, people may experience swollen lymph nodes, usually in the armpit or neck, which can be tender to the touch. Other symptoms may include fever, headache, fatigue, and a general feeling of being unwell. In some cases, people may also experience rash, sore throat, or conjunctivitis (pink eye). It’s essential to seek medical attention if symptoms worsen or persist over time, as this can indicate a more severe infection.
In some cases, Cat Scratch Fever can lead to more severe complications, such as Parinaud’s oculoglandular syndrome, which is characterized by conjunctivitis and swollen lymph nodes in the eye.
