Chapter 88: The Outbreak of the Epidemic
The incubation period of natural infection of African swine fever is 5~9 days, often shorter, and the clinical experimental infection is 2~5 days, the body temperature rises to 41 at the onset of the disease, which lasts for about four days, until 48 hours before death, the body temperature begins to drop as its characteristics, and the clinical symptoms are not shown until the body temperature drops, so the symptoms are different from the symptoms when the body temperature of swine fever rises, during the first three to four days of fever, the appetite of the pigs shows extreme vulnerability, the pigs lie in the corners, forced to catch up and ask it to move, it shows extreme fatigue, especially the hind limbs.
Rapid pulse, cough, rapid breathing about one-third, dyspnea, serous or mucopurulent conjunctivitis, some strains can cause bloody diarrhea, vomiting, blood changes like swine fever, from three to five cases, showing a 50% decrease in the number of white blood cells, lymphocytes are also reduced, leukocyte anemia occurs when the body temperature rises, and the number of white blood cells drops to 40% on the fourth day without decreasing, and the increase in the number of immature neutrophils can also be observed, often death on the seventh day after fever, or death after only one or two days of symptoms.
Two days passed in a hurry, and on the side of Jiang Yuanguo's farm, the number of quarantined pigs increased from two to twenty.
This ultra-high incidence rate made Jiang Yuanguo's complexion even more ugly.
At the same time, Jiang Yuanguo received calls from Hu Hanliang and Jiang Zhoucheng.
I received a call from Hu Hanliang because he also had this symptom on his side, unlike Jiang Yuanguo, Hu Hanliang directly killed nearly 200 pigs, and the situation is getting worse.
And Jiang Zhoucheng's call made his guess come true.
"Yuanguo, you have to pay attention to the situation of the farm on your side, once the disease recurs, immediately isolate, and after death, it will be directly landfilled or incinerated. The relevant directives have been issued by the government. In addition to the situation on your side and Hu Hanliang's side, there are already three urban areas that have the same symptoms. Officials have confirmed that this is indeed African swine fever, so you should take precautions. As for the loss, you don't have to worry, the government will subsidize it according to the loss of each farm. ”
The African swine fever incident swept all over the country in a short period of time, and the price of pork also rose. All the cases of African swine fever on the market have been identified as epidemic areas, and the farms and government officials have labeled this area as an epidemic area, and carried out disinfection and protective treatment.
The state department has also begun to develop a vaccine to suppress African swine fever. Although this work may be a long-term thing, if it is not done, maybe African swine fever will always exist in China in the future.
So, what needs to be done, still has to be done.
Fortunately, Jiang Yuanguo Farm was found in a timely manner, and epidemic prevention and disinfection were done in time, but in just one week, there were still 548 cases and more than 100 deaths. And Hu Hanliang's pigs died more than 1,000 directly, and cooperated with the relevant departments to cull them.
This is a huge loss for the farm.
Fortunately, the government's policies have been implemented, and at the end of the week, the local animal disease prevention and control agency called Jiang Yuanguo in advance, saying that they would immediately send people to the farm to carry out disease monitoring and investigation, and carry out swine fever vaccine immunization. At the same time, they also told Jiang Yuanguo about some prevention and control work.
Immediately afterwards, Jiang Yuanguo quickly convened a meeting and told everyone all the latest news he had received before.
"To sum up, there are four things, let me tell you. Jiang Yuanguo's expression was very solemn, and the atmosphere in the conference room was also very serious, looking at the faces in front of him, Jiang Yuanguo took a deep breath and continued, "First of all, this time African swine fever is actively extensive, although we have controlled the epidemic, but when we work every day, we must wear protective clothing, remember this." ”
Everyone nodded their heads.
I only heard Jiang Yuanguo continue: "The second thing is good news, African swine fever is not a zoonotic disease, although it is fatal to pigs, it is not harmful to people, and it is a typical pig-borne virus. ”
"The third thing is that the government will be responsible for setting up disinfection stations in the epidemic areas to deal with the epidemic on the one hand, and on the other hand, to avoid the spread of the virus through direct or indirect contact with people and vehicles. ”
At this time, I heard Zhou Wenshan speak: "Then can we still sell pork now?"
"That's the last thing I'm going to say. Jiang Yuanguo said loudly, "high temperature, disinfectant can effectively kill the virus, so do a good job in farm biosecurity protection is the key to the prevention and control of African swine fever, although the African swine fever virus is relatively stable in the environment, but it is easy to inactivate in the process of pork cooking, 70 ° to 75 ° heating for more than 30 minutes, the virus will be killed." ”
After a pause, Jiang Yuanguo continued: "And every batch of pork we transport next will be strictly inspected and quarantined by the relevant government departments, and as long as the inspection is qualified, it can be sold normally." ”
After finishing speaking, Jiang Yuanguo picked up the water cup in front of him and poured it hard, and then said, "Do you have anything to add?"
I only heard Jiang Xiaoliang say solemnly: "Let's hurry up and deal with the epidemic." ”
Jiang Yuanguo nodded and said, "Okay, then that's it, everyone will take the people under their hands to conduct inspections from time to time, remember, you must wear protective clothing." ”
When the words fell, everyone nodded and got up. Outside the farm, there are constantly people in protective clothing walking around, hurried, but methodical.
As soon as Jiang Yuanguo walked out of the conference room, he received a call from other farmers in the village, who also asked about swine fever.
At the same time, Jiang Xiaoliang's phone rang from time to time, and their rhetoric was the same as Jiang Yuanguo's. Hearing that the government will send someone over soon, the big guy's heart is missing a stone.
After a few days of busy day and night, the epidemic situation of all farmers was finally brought under control, and at the same time, people sent by local institutions also arrived in Jiangjia Village.
Today, Jiangjia Village is already a well-known breeding village, of which several Jiangyuan countries are the largest, and other farms are distributed in various sections of the mountain. They cooperated with government officials in conducting a regional survey, which led to the identification of several sites where disinfection stations would be built.
At the same time as the establishment of the disinfection station, the epidemic monitoring and investigation and swine fever vaccine immunization were also carried out at the same time.
The disinfection station of the farm in Jiangyuanguo was built on the bridgehead in the distance, and the person in charge was surnamed Du and called Du Zhennan. After the disinfection station was completed, Du Zhennan specially talked to Jiang Yuanguo and Jiang Xiaoliang, one is to understand the current epidemic situation of the farm, and the other is to hope that he can fully cooperate with the investigation.
"Teacher Du, rest assured, these are all things that are within my responsibility. Jiang Yuanguo said with a smile.
Immediately afterwards, from the day he discovered the epidemic, he told Du Zhennan about the situation of the farm in detail, and the latter nodded while recording it. He has already gone to the pig shed to inspect it, and it is not far from what Jiang Yuanguo Jiang Xiaoliang said.
After Jiang Yuanguo finished speaking, Du Zhennan asked a few more related questions, and both of them answered them one by one.
"Okay, that's pretty much it, see if you guys have any questions. After the last word was written, Du Zhennan closed the cap of the pen and slowly spoke.
Jiang Yuanguo thought about it, and still asked: "What measures do our government take to monitor and investigate?"
Du Zhennan responded and said: "I believe you have also seen that in addition to setting up disinfection stations, we will take measures such as blockade, culling, harmless treatment, and disinfection, and prohibit all pigs and susceptible animals and products from being transported into or out of the blockade area. The lockdown lasts for 6 weeks, and the swine fever area can only be lifted if it passes the report assessment and acceptance of the provincial animal husbandry and veterinary department. ”
Jiang Yuanguo and Jiang Xiaoliang nodded while listening, only to hear Jiang Xiaoliang ask: "We have isolated the sick pigs and pigs, do the pigs still need to be investigated?"
"Of course. Du Zhennan nodded, "This epidemic is very serious, not only pigs, for example, we have designated Jiangjia Village as an epidemic point, with the edge of Jiangjia Village extending 3 kilometers outward as the epidemic area, and extending 10 kilometers from the edge of the epidemic area outward as the threatened area, with the goal of eradicating the epidemic to carry out epidemic disposal work." ”
Hearing this, Jiang Yuanguo and Jiang Xiaoliang couldn't help but gasp, glanced at each other, and saw shock in each other's eyes at the same time.
"Teacher Du, rest assured, we will fully cooperate. Jiang Yuanguo said with palpitations.
Du Zhennan sighed and said: "No one expected this to happen, there are five epidemic points in City A alone, but rest assured, as long as the laboratory test of the pigs in the epidemic area is negative, after completely eliminating the risk of the spread of the epidemic, you can continue to raise or slaughter." ”
Hearing this, the tight string in Jiang Yuanguo and Jiang Xiaoliang's hearts loosened slightly. They have heard that some small farms have carried out all the culling and follow-up treatment, and the losses are heavy. Hearing Du Zhennan's words at this time, the two of them relaxed a little in their hearts.
The situation was almost understood, so Du Zhennan offered to go to the pig pen to have a look, and Jiang Xiaoliang took him there.
The two left on the front foot, and Jiang Yuanguo on the back foot made a phone call to Hu Hanliang.
"Hey, Yuanguo, how are you doing over there?" Hu Hanliang quickly picked up.
Jiang Yuanguo explained the situation clearly in three or two sentences, and listened to Hu Hanliang: "It's almost the same on my side, alas, this time after tossing, I don't know how much we will lose, but fortunately, we have a thick foundation and can withstand the toss." ”
"Yes, this lockdown is estimated to have to be suspended for nearly two months. Jiang Yuanguo took a deep breath and said.
The two chatted about the prevention and control work again, and then hung up the phone.
When Jiang Yuanguo walked out of the dormitory, he saw the busy staff, the air was filled with the smell of disinfectant, not only the farm and slaughterhouse, but also the office building was disinfected countless times.
Watching the sick pigs being carried to another place, Jiang Yuanguo couldn't help but feel a pain in his flesh, but compared to these losses, the farm can resume normal operation as soon as possible, which is the most important thing.
After a few days, the dead and sick pigs on the farm were gathered in one place for centralized treatment, which took half a month.
At the same time, Jiang Yuanguo learned that other farms in Jiangjia Village were also dealing with dead and sick pigs.
