Cat scratch fever (also known as cat scratch disease, CSD) is an infection caused by the bacteria Bartonella henselae which is carried in cat saliva. The bacteria is one of the most common types in the world. While cat scratch fever is usually a mild condition, people with weakened immune systems and young individuals tend to be more at risk of acquiring a severe infection.
In the case of CSD, cats are the primary culprits behind the majority of infections in humans. Many people may notice signs after a scratch and ignore them, but it is crucial to take action when you see a difference in your skin and other parts of your body.
