"It's not a bacillus, it's a cocci." The examiner looked up and said to the doctor and the disease control staff who came in with him.

If it's not a bacillus, it's not plague.

"I'll take a look." Section Chief Zhang of the county CDC took the initiative to see the results of the cerebrospinal fluid smear.

The examiner moved out of the way, and Section Chief Zhang leaned over to the microscope and found that the bacteria in the field of vision were stained purple, some blue-purple, arranged in strings, which was a typical gram-positive streptococcus.

There are many types of streptococcus, and there are many kinds of diseases that can cause human diseases, and it is widely found in nature, such as soil, water, milk, and the nasopharynx of normal people.

The streptococci found in the cerebrospinal fluid of patients today are certainly pathogenic, but to determine which one it is, it is necessary to isolate the strain by culture and do further biochemical identification.

The following confirmatory experiments will take time, and if more data are available, it can also help to identify the pathogen.

A little nurse hurriedly ran to the laboratory department, "Doctor Li, patient Zhao Yong has woken up." ”

It is a good thing that some patients wake up, indicating that the treatment is effective, and they can also ask some flow questions.

Under the guidance of the attending doctor, Section Chief Zhang of the county disease control and control entered the ward wearing protective clothing.

Among the three, Li Xiaohua and her husband Zhao Yongcai are still in a coma, their faces are blue, and they have antibiotic drips on their arms.

Zhao Yongfa was the only one, because his symptoms were milder than others when he was admitted to the hospital, and after the antibiotic treatment and other symptomatic treatments, his spirit has improved and he can answer questions.

Zhang Zhang, the head of the county disease control department, asked Zhao Yongfa, "What is your name?" ”

"Zhao Yongfa."

"Have you been exposed to rats lately?"

"No, I have a lot of cats at home, and I don't have mice."

"What were you doing before you got sick?"

"Killing pigs in the morning and eating together at noon, my wife was wrong at the dinner table, and then my brother and daughter-in-law were not feeling well, so I asked my brother to drive a tricycle to send people to the county hospital, but I didn't expect to be planted in the ditch just out of the village...... How is my daughter-in-law? What's wrong with me? I have a terrible headache, and what about my brother and sister-in-law? ”

As soon as Zhao Yongfa woke up, he remembered his daughter-in-law.

Li Xiaoju had died, and Section Chief Zhang didn't want Zhao Yongfa to be too sad in this situation, so he changed the topic, "They are next door, are you sure that the symptoms occurred during the lunch meal?" What do you eat for lunch? ”

"Some dishes made from pork and pork offal, and a pot of rice was stewed."

Killed pigs and ate pork, the germs were arranged in a chain under the microscope, and the gram-positive bacteria were ...... Could it be that a human infected with Streptococcus suis?

This thought jumped into Section Chief Zhang's mind for the first time, although he had not dealt with human streptococcus suis infections before, but he had received training.

Section Chief Zhang of the county disease control continued to ask, "Did the pigs you killed in the morning get sick?" Symptoms such as lack of energy or poor appetite. ”

Zhao Yongfa, who had just woken up, had his eyes flickering, his mouth opened and closed, closed and opened, and he didn't speak for several seconds.

Section Chief Zhang has rich experience in flow investigation, and when he saw this situation, he knew that Zhao Yongfa had something to hide.

"To be honest, try to be as detailed as possible, your wife is dead, and the illness of you and your brother and daughter-in-law may also be related to your experience in the morning, and you can only help you if you tell us the truth."

"What? My daughter-in-law is dead? Zhao Yongfa was emotional.

The attending doctor who has been accompanying him, "Zhao Yongfa, your wife's condition was already very serious when she was sent, and she died after rescue, and the rest of the people also have similar symptoms, you are still saved, you have to say anything about it, which will help us diagnose the cause." ”

Zhao Yongfa was lying on the hospital bed, with tears streaming from the corners of his eyes, and began to say: "I got up this morning and went to the pigsty to feed the pigs, and found that one of the big white pigs was dying, there was blood foam at the corner of his mouth, and the other pig was not in a good mental state.

I thought that the big white pigs that I had been raising for a year couldn't just die, so I called my cousin's family over and killed them before they died.

The meat of the dying pig was sold to the pork dealer, and one of the pigs in a slightly better state of mind was ready to keep the year's goods.

The pigs of the two pigs were not thrown into the water, and after cooking, they were made into a dish at noon and eaten a little, and the rest was still at home, and they were also ready to stay until the New Year.

Oh, by the way, I also gave the meat to a few good neighbors, and each family didn't give much, only two or three catties each. ”

Section Chief Zhang's heart sank, this is bad, Zhao Yongfa's family's illness is likely to be infected by sick pigs, it is human infection with Streptococcus suis, and the sick pork was also distributed to neighbors, and one of the sick pork is not known where to sell.

Section Chief Zhang: "Where did the sick pork go?" And which neighbors did the sick pork distribute to? I want a specific list, and the more detailed the better. ”

Zhao Yongfa said the names of several people, and Section Chief Zhang wrote them down one by one.

After the questioning, out of the ward, in the corridor of the hospital, Section Chief Zhang said to the attending doctor, "The patient is likely to be infected with Streptococcus suis, and I will send the specimens collected today to the Municipal Center for Disease Control and Prevention for identification, and the results will be fed back to you in time." ”

Doctor: "Human infection with swine streptococcal disease?" This is a zoonose, since I came to work in the county hospital, I have not encountered this kind of case, I have only seen it in books before, this disease is easy to treat, it is very rare. ”

"Your hospital is busy first, and our county CDC has to report the epidemic to the Municipal CDC, and we have to go to the scene to do the investigation. This guy sold the sick pork and distributed it to the neighbors, and it is estimated that many people have been infected, and we have to stop it quickly. ”

Lianhai Center for Disease Control and Prevention, Emergency Office.

When I was about to get off work in the evening, there were gradually more people in the emergency office that had been deserted for a day.

Originally, Wang Xiaoxiao was the only one sorting out the news on the Internet, and Zhou Lao, Gao Fei, Lu Li and Xiao Chu had just returned from Qingcheng Mountain to guide the local county disease control to conduct a field rat density survey.

Approaching the end of work, the sky became dark, and the four people rushed back to the office, seeing that Wang Xiaoxiao was the only one in the office, Xiao Chu took the initiative to ask: "Where is Sister Yanan?" ”

"Experiments in the laboratory building. Xiao Chu, what are you looking for Sister Yanan? ”

"It's okay, just ask casually, Sister Yanan usually does experiments?"

"Well, at the beginning, Sister Yanan was also a test student, and later came to the scene to do a flow survey, she still has scientific research topics on her body, and she usually goes to the laboratory to work when she is a little free."

Xiao Chu stared at Gu Yanan's position, thoughtful.

"Xiao Chu, what are you in a daze?" Wang Xiaoxiao noticed Xiao Chu's abnormality, and every time he mentioned Gu Yanan's affairs, Chu Qinggeng was always like this.

"Oh, I want to go to the laboratory building to have a look, and I want to learn more from Sister Yanan."

Xiao Chu put down the things in his hand and prepared to go to the experimental building next door, but Gu Yanan pushed the door and came in.

"Sister Yanan, is the experiment done? Xiao Chu was about to go to the laboratory building to find you, and he said that he wanted to learn more from you. Wang Xiaoxiao was gossiping about the situation just now.
