Cat-scratch disease is an infection caused by Hansebaltonia, which is a polymorphic Gram-negative small bacillus, and the bacteria can be observed through a microscope. So, what are the clinical manifestations of cat-scratch disease? Below, learn more about it. Clinical manifestations of cat-scratch disease The typical primary injury is an erythematous, crusted papule (rarely purulent), 2 to 6 mm in diameter. 2 weeks produce localized lymphadenopathy, often unilateral, on the scratch side (affecting axillary, upper talon, submandibular, cervical or inguinal lymph nodes). The lymph nodes are initially firm and soft, but later become volatile and may have fluid flow and form fistulas. The patient’s symptoms of fever, malaise, headache, and anorexia may coincide with lymphadenopathy. If a person is infected with cat-scratch disease, non-purulent inflammation, such as erythema or papules, usually appears locally at the scratch or bite site after 3-7 days; followed by granulomatous or purulent lymphadenopathy on the head and face, with the main symptoms being low fever, headache, chills, general malaise, malaise, anorexia and vomiting. After the diagnosis of cat-scratch disease, if timely symptomatic treatment, generally good prognosis, only immunocompromised people may occur serious systemic conditions, such as heart, brain and other complications.
