Can rural pigs transmit African swine fever? On what basis?

Rural free-range, due to the low feeding density, coupled with free-range, pigs have stronger immunity and stronger resistance to African swine fever virus, and will persist for a longer time overall. However, if we only compare the number of pig farms that have been recruited, "rural pigs" are still much higher than large-scale pig farms, and there are even pig-free villages in many places. It's just that due to the large number of "rural pigs", the remaining number is not expensive.

Don't make the mistake of thinking that "rural pigs" do not transmit African swine fever, "rural pigs" are not Iron Man, and they cannot stop the invasion of African swine fever virus at all.

African swine fever is a highly contagious infectious disease, the occurrence of infectious diseases must have three conditions, namely the source of infection, transmission route and susceptible animals, only three conditions at the same time, will lead to the occurrence of disease, so African swine fever susceptible animals are pigs, including domestic pigs and wild boars, but it does not mean that pigs will be infected, but also African swine fever virus, and the virus contact with pigs, will lead to the disease, African swine fever is a highly contagious infectious disease. Therefore, whether it is a small number of pigs raised in rural areas or a large number of pigs on a large scale, as long as they meet the conditions for the occurrence of infectious diseases, they will cause disease.

Mosquitoes and flies are one of the main routes of transmission of ASF virus. Large-scale farms, regardless of whether they are in the event of an ASF outbreak or not, will have a planned mosquito control. Farm ventilation windows are generally compensated with screens, and pig manure water will be treated centrally.

For example, biogas digesters, biological bacteria fermentation, three-dimensional agricultural consumption, etc. Most of the pig farms are equipped with photocatalyst mosquito killer lamps, and the stagnant water and odorous ditches around the pig farm will be drained or closed, and regular disinfection and sterilization or chemical mosquito control will be taken. However, due to the small scale of individual free-range farming, the related facilities are relatively old.

Therefore, free-range breeding is far inferior to large-scale breeding in mosquito control. In the process of breeding, do not have a fluke mentality, conscientiously do a good job in the anti-non-work of the pig farm, prevent mosquitoes, carefully purchase feed for swine fever areas, and do a good job of self-disinfection of breeders.

Personally, I don't think it will be possible under normal circumstances, and the resistance of rural pigs is still a little stronger.

There is no basis for the claim that pigs raised in rural areas can transmit African swine fever.

Of course, it is possible that sometimes the breeding density is too high, or the pigs are not strong enough to contract such diseases.

Once a pig in <> pigsty is infected with African swine fever, the whole herd is at risk of infection and needs to be culled by the whole herd. After an outbreak of African swine fever in a pig farm, it can lead to the infection of the entire farm in 1-10 days without timely treatment. African swine fever, commonly known as "rotten intestinal plague", is a more dangerous and high mortality infectious disease in pig diseases, the disease only infects pigs under natural conditions, pigs of different sexes, ages, breeds of pigs and wild boars are susceptible, and can occur all year round.

1. If a pig is infected with African swine fever, will all the others be infected?

1. Once a pig of the infiltration tribe is infected with African swine fever in the pigsty, the whole herd is at risk of infection and needs to be culled by the whole herd. African swine fever, commonly known as "rotten intestinal plague", is an infectious disease with a very dangerous and high mortality rate in swine diseases, the disease only infects pigs under natural conditions, pigs and wild boars of different sexes, ages and breeds are susceptible, and can occur all year round. After an outbreak of African swine fever in a pig farm, it can lead to the infection of the entire farm in 1-10 days and death within 10-15 days without timely treatment.

2. The incubation period of African swine fever virus is more extreme, generally about 4-9 days, at this time, the activity and feeding of pigs will not be affected, and the appearance is not abnormal, but the virus will multiply in large numbers in pigs and spread rapidly, so as to enter the onset period. When the sick pig will begin to appear lazy limbs, weakness, anorexia, and gradually increase body temperature, ** small reddish-purple patches, with the aggravation of the disease, the cyanosis will gradually expand, and the body temperature will last to more than 40 degrees. Death will occur on the 7th day after fever, and death will occur in 1-2 days after severe disease, and the drop in body temperature of pigs in the early stage of death is the biggest difference between it and other epidemics.

2. Prevention and control measures for the occurrence of African swine fever

1. It is forbidden for outsiders, vehicles and other poultry to enter the farm, and clean up in time after the occurrence of swine fever; The feed and utensils of the farm should be disinfected, and the pigs cannot be fed with swill, which is easy to carry the virus; Do not raise free-range pigs, wild boars or external insects will cause pigs to get sick, observe the situation of pigs at any time, such as vomiting, high fever, diarrhea, redness on the body, to do a good job of isolation; Closing the farm in the event of an outbreak and treating it early can reduce losses. Pigs with low immunity are prone to disease, and timely vaccination and disinfection with alkali or 100 poisons are also very important.

2, regular preventive injection, spring and autumn every year, in addition to adult pigs generally carried out a swine fever rabbit attenuated vaccine injection, weaned piglets and newly purchased pigs should be timely epidemic prevention injection, the newly purchased pigs should be isolated for 30 days, confirmed disease-free, and injected swine fever vaccine can be mixed after the group, swine fever often epidemic areas, piglets are born 21-30 days old injection once, 55-60 days old piglets weaned and injected again.

<> African swine fever does not infect humans, nor does it infect animals other than pigs, and has no direct impact on human health and food safety. For pigs, African swine fever is very deadly, characterized by a short course of disease, and the mortality rate of the most acute and acute infection is as high as 100%. To prevent African swine fever, mosquitoes, flies, rats, and parasites should be killed; Do a good job of disinfection of enclosures, tools, medicines, feed, transport vehicles and people entering and exiting; Do a good job in the discharge of pollutants (including feces, sewage, etc.) in enclosures; Be careful not to use swill to feed the pigs; It is also necessary to improve the immunity of the herd itself.

1. Does African swine fever infect people?

1. African swine fever is not a zoonotic disease, does not infect humans, and does not infect other animals except pigs, and has no direct impact on human health and food safety. Judging from the research, it is unlikely that African swine fever will mutate to spread humans.

2. African swine fever is an acute, febrile and highly contagious infectious disease of pigs caused by African swine fever virus infection, which is very fatal to pigs, and is characterized by a short pathogenesis process, and the mortality rate of the most acute and acute infection is as high as 100%. Although the virus has a high lethality rate, it is very difficult for the virus to survive in high temperatures, and when the temperature reaches 55 for 30 minutes or 60 for 10 minutes, it can kill the virus.

2. How to prevent African swine fever

1. Do a good job of killing.

Do a good job of killing mosquitoes, flies, rats, and parasites, so as to prevent the bacteria and viruses they carry from spreading various diseases. The pig house is nailed with a window screen, and the fly lamp is hung in the house, and the pesticides are timely to kill flies, mosquitoes, rats and various parasites.

2. Do a good job of disinfection.

The disinfection of the pig farm should be implemented, and the disinfection inside and outside the pig house should be done regularly, including the disinfection of the enclosure, tools, medicines, feed, transport vehicles and personnel entering and exiting.

3. Do a good job in the discharge of pollutants in the enclosure.

African swine fever is not only transmitted through the air, but also if feces and sewage are not properly discharged, so it is necessary to do a good job in the pollution control of enclosure emissions. Enclosure pollutants include feces, sewage, etc.

4. It is strictly forbidden to use swill to feed pigs.

Swill is leftovers. If the pork in the leftovers is not heated at a high temperature enough to kill the virus in it sufficiently, and then it is used to feed the pigs, it is likely to cause the spread of the virus.

5. Improve the immunity of the pig herd.

Strengthen the pig's own immunity, then the pig is less susceptible to viral diseases such as African swine fever. Generally, the mixture can be mixed with Qingwen Taibao + Blue Circle Non-Taibao + Tilmicosin, which can effectively purify the blue ear ring, avoid immunosuppressive factors, and improve the immunity of the pig herd and the ability to resist viruses and wild poisons.

**There is no rule that prohibits rural pig breeding, but it is strictly forbidden to raise pigs with kitchen waste in rural areas.

Due to the outbreak of African swine fever, on the afternoon of January 8, 2019, the Ministry of Agriculture and Rural Affairs organized a national remote training on African swine fever prevention and control, focusing on implementing the main responsibility of animal epidemic prevention and strengthening the epidemic prevention management of large-scale pig farms and breeding pig farms.

Pig farmers should resolutely overcome the luck mentality, strictly implement the main responsibility of animal epidemic prevention, and consciously accept the supervision and inspection of the veterinary department. It is necessary to further improve the epidemic prevention system, strictly clean and disinfect vehicle personnel, put an end to the use of kitchen residues to feed pigs, and resolutely block the transmission route of the epidemic.

It is necessary to strengthen personnel training, standardize epidemic investigation reports, and never allow the epidemic to be concealed. At the same time, it is necessary to improve the predictability of the market situation, seize the opportunity, actively fill the column, stabilize the sow inventory, and properly arrange the production of pigs.

Yu Kangzhen, Vice Minister of the Ministry of Agriculture and Rural Affairs, pointed out that through the joint efforts of all parties, the current national epidemic situation is in a state of sporadic sporadic sporadic occurrence, and the momentum of the epidemic has begun to slow down, and the epidemic is generally controllable.

The market for pork products is sufficient and continues to be stable. However, at the same time, it is necessary to see that the traditional breeding structure is difficult to fundamentally change in a short period of time, the transmission route of the epidemic is complex, and the prevention and control situation is still complex and severe.

African swine fever is highly contagious and not afraid of low temperatures, and the African swine fever epidemic in neighboring Russia has lasted for about 10 years, so the arrival of winter cannot stop the spread of the epidemic.

At present, African swine fever has caused 21 provinces to be infected, and large-scale farms, pig breeding farms, small farmers, wild boars, etc., have been infected. However, African swine fever is not a zoonotic virus, it is only limited to transmission between pigs, and after the pork has undergone strict quarantine, consumers can eat it normally, and when cooking, as long as the pork is cooked.

This starts with the transmission route of African swine fever. Because African swine fever is a highly contagious infectious disease, it can be transmitted by contact, and it can also be transmitted through feed, swill, items, etc., contaminated with the virus. Therefore, if the pig is infected with the epidemic, it will spread to the rest of the pigs in the farm, if the sick pig is transported over long distances, all the way to eat and drink Lazar to leave the virus, it may cause a large area of the epidemic to spread, if the sick pig is eaten, it may enter the farm again through swill, thus infecting other pigs.

To sum up, from the perspective of cutting off the transmission route, prohibiting sick pigs from entering the market and culling them all is one of the important means to control the epidemic. Since the outbreak of African swine fever in August, every time an epidemic is found, the pigs in the field will be culled and harmless, and the epidemic area will be designated to restrict the export of pigs and pork. According to the data of the Ministry of Agriculture and Rural Affairs, at present, African swine fever is mainly sporadic in multiple places, and there has not been a single case of secondary and large-scale spread of infection, indicating that the current epidemic prevention measures can effectively control the African swine fever epidemic that has occurred.

African swine fever only infects pigs, does not infect humans, nor does it infect other animals except domestic pigs and wild boars, and does not belong to zoonotic diseases.

African swine fever virus is not contagious to humans, but it weakens the immune system of pigs and makes them more susceptible to other diseases. This will not only lead to a decrease in the quality of pork, but also allow pigs to carry other pathogens, some of which can cause harm to the human body, so do not eat pork infected with African swine fever.

Because this pathogen is not a match for people, it cannot be transmitted.

The swine fever virus is only specific to pigs, not humans.

This is only a virus specific to pigs, so it is not transmitted to humans.

Only people who eat pork with swine fever can be infected.

Because pigs have receptors that match the virus.

Because it's a disease that spreads from pig to pig.

There are no receptors for this virus in humans.

Because the human body is immune to this virus.

The African swine fever virus can be transmitted from humans to pigs, and at present, the virus is not contagious to humans, and this virus is extremely vigorous!

Although it will not infect people, the harm and potential are not small, and if the African swine fever virus mutates, it will be a new plague catastrophe in the world.

So don't let the sin go any further, because the plague and sin are "good friends."

The only reservoir of ASF is pigs, and neither humans nor other animals can be infected by the SSF virus. Pork can be eaten normally when cooked because the swine fever virus can only survive for 80-3 seconds in water.
