Answer 1

Cat Scratch Disease

(1) The black cat arched its back, flattened its ears, and, with a low hiss, slicing Lucas’ arm with sharp claws. (2) A red line appeared on Lucas’ skin, and he gritted his teeth against the sting. (3) Little did he know that bacteria called Bartonella henselae had just entered his body.
(4) Cat scratch disease (CSD), sometimes called cat scratch fever, is a bacterial infection that can affect humans who have been scratched or bitten by a cat. (5) The symptoms of CSD include fever, headache, fatigue, poor appetite, and swollen lymph nodes. (6) Major complications are rare. (7) For healthy individuals, either the body’s immune system can clear the infection or the patient can take an antibiotic.
(8) About 40 percent of cats will carry the bacteria during their lifetime. (9) Cats don’t have any symptoms once infected, so pet owners cannot tell if their cats are carriers. (10) The best ways to prevent CSD are washing cat bites and scratches with soap and water, do not allow cats to lick your wounds, and going to the doctor at the first sign of wound infection.
