Xiao Qingyin asked her, "Is it very itchy?"

The maid nodded.

Xiao Qingyin touched her forehead and found that she had a fever.

"You have cat scratch disease."

Xiao Qingyin replied.

The maid looked dazed.

It's hard to believe that there's a disease called "cat scratch disease".

Xiao Qingyin continued, "This disease is self-limiting and usually heals on its own in two to three months, but if the immune system is weak..."

She stopped abruptly at this point.

If a person has a weakened immune system, contracting cat scratch disease can cause enlarged lymph nodes, organ damage, and lesions of the retina and central nervous system.

The symptoms matched those of Ms. Wu perfectly!

She suddenly understood.

They quickly gave Wu a full-body examination, leaving no inch of her skin unchecked.

Finally, a faint white mark was found on her ankle.

She asked the maid, "Was your mistress scratched on the ankle by a cat?"

“Yes,” the maid replied. “The lady was scratched by a dark cloud nine months ago, but it healed quickly.”

Six months ago... Xiao Qingyin recalled the incubation period of cat scratch disease, which could be as short as a few days, or as long as several months or even more than a year.

When Wu was scratched, he was likely infected with Bartonella henselae, but the infection had not yet manifested.

My immunity has recently dropped significantly, and I developed Hanse Baltonne, which triggered a severe reaction.

Once the symptoms are identified, it becomes easier to prescribe medication.

She prescribed a new formula, had someone prepare the medicine and decoct it for Wu Shi to drink. The maid also gave her a formula and made a topical ointment for her.

Wu's fever subsided on the second day after taking the medicine.

A week later, the lymph nodes on her body had shrunk by more than half, and she had basically recovered.

Shopkeeper Yu gave the eight-eyed zither bead to Xiao Qingyin and said gratefully, "You are truly a miracle doctor; your medicine has cured my illness so quickly."

Xiao Qingyin stroked the familiar dzi bead and asked him, "Who gave you this bead? What is their purpose in having you call me here?"
