What is the prevalence of Cat-scratch Disease?

Cat-scratch disease, also known as cat-scratch fever, is a relatively common infectious disease caused by the bacterium Bartonella henselae. It is primarily transmitted to humans through scratches or bites from infected cats, particularly kittens. The prevalence of cat-scratch disease varies depending on several factors such as geographical location, population density, and cat ownership rates.

While exact prevalence rates are challenging to determine, studies suggest that cat-scratch disease is not uncommon. In the United States, it is estimated that around 12,000 people are diagnosed with cat-scratch disease each year. However, many cases go unreported or undiagnosed, so the actual number of infections is likely higher.

Prevalence is higher in certain populations, such as children and individuals with weakened immune systems. Children are more susceptible due to their close interactions with cats and their tendency to engage in rough play. Immunocompromised individuals, such as those with HIV/AIDS or undergoing organ transplantation, are at a higher risk of developing severe complications from cat-scratch disease.

It is important to note that simple preventive measures can significantly reduce the risk of contracting cat-scratch disease, such as regular handwashing after handling cats, avoiding rough play, and keeping cats indoors. If symptoms such as swollen lymph nodes, fever, or fatigue occur after a cat scratch or bite, seeking medical attention is crucial for proper diagnosis and treatment.
