While sending Shi Guohua to the hospital, Shi Guohua's wife Xiao Fang also showed symptoms.

After Shi Guohua died after rescue efforts failed, Xiao Fang was hospitalized and went directly to the intensive care unit.

Because of the hospital's previous experience and the timely arrival of the provincial expert team to adjust the treatment plan, Xiao Fang's condition stabilized, and after three days, she was transferred from the intensive care unit to the general ward.

When the investigation of the flow disease in Stone Village reached here, there was no follow-up.

Ye Zhenzhen took the information and asked curiously: "Senior Nan, what about the rest of the information? It shouldn't be over yet, the whereabouts of the sick and dead pigs, the pig farm in Shi Guohua's mountain, these contents have not been investigated clearly." ”

Nan Zhiqiao: "That's all for the information, the flow of Stone Village hasn't ended yet, it could have ended today, but it's ......"

Nan Zhiqiao wanted to speak and stopped, Ye Zhenzhen asked, "But what's wrong?"

"When I was in Stone Village in the morning, you called me, my mobile phone suddenly ran out of battery, and when I contacted you again after charging, your mobile phone was turned off, and the person was already on the plane, there was no way, I could only end the work here and go to the airport to pick you up. ”

It turned out that this was the case, Ye Zhenzhen felt very sorry, "I'm sorry, Senior Nan, I will definitely cooperate with the work tomorrow and make up for the progress." ”

Nan Zhiqiao said with a smile: "There is a lot of work tomorrow, in addition to investigating the pig farm on Shiguo Huajia Mountain, we also have to investigate the pig breeding situation of farmers in the entire Stone Village." ”

It's just a village, there shouldn't be many households, Ye Zhenzhen originally thought so in her heart, but Nan Zhiqiao then added, "There are more than 100 households in Stone Village, and basically every family raises pigs, like Shi Guohua's scale, other farmers are small and free-range, and it takes a lot of time to investigate." ”

Ye Zhenzhen calculated in her heart, more than 100 households, it will take a lot of time to investigate from house to house, and if there are only two people, the survey form will not be completed in a day.

"Senior Nan, will the two of us go to Stone Village tomorrow?" Ye Zhenzhen asked.

"In addition to the two of us, there are three other people, Xiao Gao and three staff members of the Yuanyang City CDC. ”

"Six people, do the flow survey in groups, so that the progress will be faster. ”

"In addition to the survey, we are also responsible for distributing some promotional materials. Nan Zhiqiao pointed to a pile of promotional materials in the corner of the room and said, "Those are just printed today, and when I go to do the flow survey tomorrow, I will distribute them for epidemic prevention propaganda by the way." ”

Ye Zhenzhen picked up a promotional material, the ink of the paper is strong, it is just printed, and then look at the content, it is a few pictures about swine streptococcal disease, and there is a text description below, once the disease and dead pigs are found, they must not be slaughtered, let alone processed and eaten, and should be reported to the animal husbandry and health departments in a timely manner, and cooperate with the relevant departments to disinfect the sick and dead pigs, bury or incinerate and other harmless treatment, and strictly disinfect the enclosure in a timely manner.

Ye Zhenzhen took the promotional materials and asked, "Are we going to disinfect each farmer's enclosure?"

"No, the scope of the epidemic is relatively wide, and after discussion by the expert group, it is recommended that the local government take the treatment measures of 'five guarantees, four noes, two subsidies, and one harmless', and the specific instructions are in the promotional materials. ”

The "five guarantees" refer to the city, county, township, village, village, and household, and the responsibility is gradually implemented to prevent the spread of the disease; the "four noes" refer to not slaughtering, not eating, not selling, not transporting sick and dead pork; "two subsidies" refers to subsidizing the cost of harmless treatment of diseases and dead pigs by farmers, as well as subsidizing the medical expenses of patients; and "one harmless" refers to the deep burial or incineration of sick and dead pigs after disinfection of sick and dead pigs.

"This propaganda measure is quite comprehensive. Ye Zhenzhen praised.

"The measures are good, and the next step is to see how strong the implementation is. ”

After reading the promotional materials, Ye Zhenzhen turned her attention to the case file again, and looked through several copies, each case has a story, among which a female patient who lives in Badan Village, Hongshan Town, named Jiang Hua, has a similar experience to Shi Guohua's wife Xiao Fang.

Three days before Jiang Hua's illness, he helped relatives kill pigs, men killed pigs, and a group of women helped to "plan" pig hair and wash internal organs, when Jiang Hua had a small wound on his hand. After the pig was killed, the owner boiled a large pot of pig offal, and everyone who helped ate a little.

Before Jiang Hua ate a few chopsticks, he felt dizzy and wanted to vomit, and finally his legs were so sore that he couldn't stand up, and there were large patches of ecchymosis on his arms and legs.

Xu Wen, a male patient from the same town and village as Shi Baocheng, had a similar experience.

A pig at Xu Wen's relative's house foamed at the mouth and died, the relatives found Xu Wen to help kill the pig, after killing the pig, Xu Wen carried more than 20 catties of pork home, just divided the pork into several pieces and put it in the refrigerator, the person felt weak and painful, and nausea and vomiting, sent to the hospital overnight, after rescue, has now recovered and been discharged.

After reading the medical records, Ye Zhenzhen summarized that this human-streptococcus suis infection case has a common point, that is, before the onset of the disease, they were slaughtered, washed, processed, and dead pigs, and the hands of severe patients have scars, the patients showed high fever, body aches, high fatigue, decreased appetite and other symptoms in the early stage of the disease, accompanied by nausea, vomiting, etc., and then subcutaneous bruising, shock and other symptoms, patients with the development of the disease, the total number of white blood cells increased, some patients have the characteristics of acute onset, severe disease, and high mortality.

These are typical features of bacterial infections!

Ye Zhenzhen sighed: "Streptococcal disease of swine belongs to the second category of animal diseases stipulated by the state, which is a zoonotic infectious disease. Streptococcus bacteria exist in healthy mammals and humans, and under the induction of reduced animal resistance and changes in the external environment, it will cause animal diseases, but I didn't expect that the harm to people is so great. ”

Ye Zhenzhen said that she was a little nervous, and Nan Zhiqiao comforted: "Judging from the current situation, if it is not for direct slaughter and contact with sick and dead pork, there is no need to panic at all." ”

"That is to say, at present, this person-swine streptococcal disease is only transmitted through contact, not through the air, and the transmission route is limited. ”

"Yes, so this outbreak is relatively easy to handle. ”

That night, after reading all the epidemic information, it was almost ten o'clock, Nan Zhiqiao and Ye Zhenzhen returned to the nearby guest house together, rested for one night, and early the next morning, everyone took the CDC's disease control car to Stone Village.

The stone village is located at the foot of a mountain, and the whole village is built on the mountain, with a small river formed by a mountain stream in front of the village and a large mountain behind the village.
