The reason for inexplicable lumps in the body of a 9-year-old girl is related to cats This year, the 9-year-old Xiaoxing (pseudonym) spent the summer vacation at her grandma's house. What makes Xiaoxing happiest is that there are several new "meats" in grandma's family. Every day when he wakes up, Xiaoxing will run to feed and tease the cat, and have a lot of fun.
Once, while playing with a cat, Xiaoxing was caught with a few blood marks on his left middle finger and left forearm. Fortunately, there was no bleeding and my family didn't take it seriously.
But after Xiaoxing returned to Shenzhen, the problem became serious...
On her left middle finger, there began to appear rashes and some pus flowed out. However, the affected area does not hurt or itch, and Xiaoxing doesn't take it seriously.
However, one day after a month, she found a lump under her left upper arm and armpit while taking a shower. It hurts a little when I touched it.

Then, my mother took Xiaoxing to Shenzhen Children's Hospital
and listened to the medical history and received the examination report, the doctor also became suspicious - there was no abnormality in the examination, but why did Xiaoxing's inner elbow swollen and the lymph nodes in the axillary are swollen? Soon, this case of unknown cause attracted the attention of doctors.
"How did your finger hurt here?"
When checking the body, Director Zheng's eyes remained at the point where Xiaoxing's fingers rupture. The child was scratched by a cat, and then developed rashes, pus, and then swollen lymph nodes. The doctor initially suspected that Xiaoxing might have "cat scratch disease".
Without further ado, on the same day, Xiaoxing's blood sample was sent for high-throughput sequencing examination. Soon, the report confirmed: Bartonin infection (that is, "cat scratch disease"). After finding the cause of the disease, Xiaoxing quickly recovered and was discharged from the hospital after some symptomatic treatment!
Everyone has heard a lot of "rabies", but everyone is still unfamiliar with this "cat scratch disease"...
What is cat scratch disease?
is the disease caused by a cat?
Cat scratch disease, full name of cat scratch disease lymphadenitis, is an infectious disease. The "real culprit" that causes this disease is Hansebalton, a Gram-negative, intracellular parasitic aerobic bacteria.
cats are the main hosts of Hansebar. If an infected cat scratches, bites, licks damaged skin, or is bitten by cat fleas, bacteria will be transmitted into the human body.

However, you can rest assured that cats will not be transmitted from humans when they are caught.
The onset of cat scratch disease is regardless of age, but most of them are concentrated between 2 and 24 years old. Children and people with low immunity are more likely to be "infected".
From being scratched by a cat to onset, the incubation period is generally 3 to 10 days, and a few cases can last for several months or even more than 1 year, which is prone to missed diagnosis and misdiagnosis in clinical practice.
If you have cat scratching disease, you will have obvious symptoms
① After the cat scratches the wound, erythema papules appear.
The pain is not obvious, and a few papules turn into blisters or pustules, and small ulcers can occasionally be seen.
② After 2 to 4 weeks, the lymph nodes in the lymphatic drainage area of this site appeared swollen.
At this time, the cat's scratching wound has long healed and is easily forgotten by patients, thus missing the important clue of "cat contact history".
Generally speaking, most children have unilateral lymph nodes (common in the elbow, armpit, neck, and groin) that are swollen, swollen and painful.
Some patients may experience systemic symptoms, such as high fever, general discomfort, sore throat, splenomegaly, conjunctivitis and even convulsions.
To avoid infection with cats, you must do these things well, regularly deworm cats, fleas, lice and other ectoparasites. They are the main transmission vectors of Barton, and deworming cats can effectively prevent cats from being caught.
Do not contact strange or stray cats at will
If you adopt stray cats, you should conduct a comprehensive physical examination and zoonotic screening.
Wash your hands after petting the cat
Wash your hands with soapy water after petting the cat, and do not let the cat lick your wound. Especially for people with children at home or with low immunity, you should avoid being caught or bitten when you come into contact with a cat.
Don't get too close when petting cats, try not to irritate the cats, so as not to get bitten or scratched.
How to "felt cats" safely?
Official release specifications!
On September 12, the China Medical Rescue Association issued the "Chinese Animal Injury Diagnosis and Treatment Code", which is the first animal Injury Diagnosis and Treatment Code in my country.
"China Animal Injury Diagnosis and Treatment Code" was compiled by the China Medical Rescue Association and more than 50 medical and health institutions and more than 200 experts across the country, and has formulated diagnosis and treatment standards for the prevention and treatment of injuries caused by more than 20 types of common animals such as dogs, cats, snakes, ants, jellyfish, and wasps.
About 40 million people in my country are bitten by cats and dogs every year, and more than 300,000 are bitten by poisonous snakes. Animal injuries such as wasps, jellyfish, ticks and other animals occur frequently. In severe cases, it can cause disability or even death, especially tetanus and rabies caused by animal injuries seriously threaten people's lives. At present, some primary medical institutions have insufficient experience in treating animal injuries, irregular diagnosis and treatment, and have a high rate of misdiagnosis and missed diagnosis.
Guo Yanhong, Inspector of the Medical Administration Department of the National Health Commission: The clinical diagnosis and treatment of many animal injuries is a common problem at our grassroots level. The National Health Commission is to strengthen the standardized diagnosis and treatment level in the clinical diagnosis and treatment of animal injuries, so that different regions and between urban and rural areas can gradually improve the diagnosis and treatment level to a proper homogeneity level.
Experts remind that you do not have excessive close contact with cats, dogs and other pets, especially do not let your pets lick the mucous membranes such as the mouth, eyes and other people.
If you are bitten by cats, dogs and other animals, clean the wound in time.
Wang Chuanlin, President of the Animal Injury Treatment Branch of the Chinese Medical Rescue Association and Deputy Director of the Emergency Department of Peking University People's Hospital: First, wash soapy water and clean water alternately. After rinsing for a quarter of an hour, go to the hospital for injection of immunoglobulin and rabies vaccine. All animal injuries are high-risk exposure of tetanus, and tetanus must be prevented correctly.
Rabies is transmitted to people after being infected with viruses. Once rabies symptoms appear, the mortality rate is close to 100%. Severe tetanus patients may experience asphyxiation, lung infection and organ failure. Even after active treatment, the global mortality rate is still 30% to 50%. Injecting tetanus vaccine is the most effective and economical way to prevent tetanus.
Wang Chuanlin, President of the Animal Injury Treatment Branch of the Chinese Medical Rescue Association and Deputy Director of the Emergency Department of Peking University People's Hospital: Our country has included diphtheria, tetanus and tetanus vaccine in the national program since 1978, which means that people born before 1978 have never received diphtheria, tetanus and tetanus vaccine. People who have not received the tetanus vaccine must fill the tetanus immunity gap, especially those at high risk groups, such as construction workers, chefs and people who often work in the field. It is recommended to inject tetanus vaccine in advance.
