Mr. Beltran, here I send him a guide elaborated by Pfizer.
IT GUIDES FOR THE PREVENTION OF CLASSIC SWINISH PEST
DIFFUSION OF THE ILLNESS

The pig is the natural guest of the virus of the PPC and as such it is the main infection source. The infected pigs eliminate the virus for nasal secretion, it salivates, he/she urinates and grounds. The semen can also be polluted. The elimination of the virus can begin before the appearance of clinical symptoms. Unfortunately, the virus eliminated in chronic infections of low virulence can go farther. They end up infecting some pigs before the birth that you/they become virus eliminadores during great part of their life.

TRANSMISSION AMONG FARMS
1. Purchase of infected pigs. These come directly from an infected farm or they have been infected during the transport or in a market. The purchase of pregnant sows can introduce the illness inside the farm when they give birth to.
2. Feeding, accidental or not, of meat or derived meat coming from infected pigs. The virus can survive up to 4 years in frozen pig meat and during several months in meat in preserves. It has been demonstrated that he/she can survive 300 days in ham of Parma. The ingestion can be or for foods non treaties or for remains of food coming from the man. In USA, in 1073, 22% of the buds in farm was due to this diffusion form. It is also the most probable form in countries free of the illness.
3. Until recently, it was not thought that the semen was a main source of transmission. In Holland, the semen was one of the main causes in the diffusion of the PPC.
4. The mechanical vehicles, such as trucks or work utensils, they are less important than other roads but their importance grows as introduction sources in free areas and closed cycles of production. The main roads can be:
& #8226, you visit
& #8226, vehicles of transport and I think
& #8226, purines. The virus usually survives only two days in grounds. But in winter this period can be prolonged up to four weeks.
& #8226, The polluted vaccines were one of the causes in the past
& #8226, Other such animals as rodents, insects pacifiers and picadors (flies, gadflies) and birds can transfer the virus, especially in short distances.

5. The boar has been especially a proven source of infection in countries of Oriental Europe.
Two notes more. The transmission for air is not very important and, in many cases, the origin of the buds is ignored, surely for lack of information on the last movements of the animals. Continuous...

Continuation,
CONTROL OF A BUD IN AN AREA OR COUNTRY
It is achieved by several roads:
1. Control of the movement of the pigs, accompanied with a test of if there have been imports.
2. Treatment for the heat of products of the pig
3. People coming from infected areas should be changed and to be washed the clothes, to take a shower and to avoid to visit pigs during at least 48 hours.
4. To clean and to disinfect the transport of animals with disinfectant of well-known activity against the virus. To point out that in Holland the transmission was for trucks that had not been cleaned.
5. Sacrifice of the animals if a bud appears. This should be accompanied with strict measures of movement restriction. The affected farms, once empty, they should be deeply cleaned and disinfected with appropriate products.

Continuation,
PREVENTION OF THE CLASSIC SWINISH PEST IN A FARM
1. Purchase of pigs of grateful origin as free of PPC. It should be assured that they take appropriate bioseguridad measures and pursuit. To avoid the purchase of pregnant sows. If not you this insurance, is recommended to suspend the purchase.
2. To establish good isolation measures. These they should be made so far from the farm as it is possible, but even in short distances they have been successful. The access should be limited and at the end of the day. The personnel should be changed clothes and to use foot-baths with disinfectant to the the entrance and to the exit.
3. The purchase of semen should come from origins free of virus. 4. To never feed the pigs with meat remains or meat products. To prohibit to the whole personnel that you/they enter with sandwiches or food with the help of products of the pig.
5. To maximize the external bioseguridad of the farm. This includes:
& #8226, To impede the access of pigs, included the boars. Strict control of the visits.
& #8226, The visits at least should allow to spend one night without having visited another farm previously. Ideally they should be taken a shower. In all ways, they should be changed clothes in the exploitation. To use foot-baths in the access points and to the entrance of each ship.
& #8226, The vehicles should clean and to be disinfected before arriving at the farm. To wet the wheels or to pulverize them with a solution disinfectants is essential to the arrival. He thinks it should be discharged from outside of the farm.
& #8226, To clean and to disinfect the jetty before and after their use. To assure that the drainage is carried out outside of the unit. Not to enter in the truck and not to let the driver to enter in the farm.
& #8226, Not to share team with other farms. If it is unavoidable, to clean well and to disinfect.

6. Control of rodents. The rodents are immune to any disinfection practice. For it, it is necessary to carry out strict controls using raticides of grateful effectiveness.
7. Control of flies. The flies are able to overcome distances of 3 km for what is also convenient the fight against them. Especially in summer where their number increases considerably. It is necessary to keep in mind that the sacrifice of pigs in next areas to the exploitation attracts the flies, which can act of transmission vehicle from the cadavers until the own exploitation. The combined use of insecticide adulticidas together with larvicidas assures an appropriate control of the insects.

The comentaio of the Dr. Cintora is very interesting, especially for those that are exercising epidemic surveillance of the illness. However at field level, we will take some of the points that the Dr. Cintora happily has put to our disposition. Luck

I would like to know what degree of relative importance they have the rodents (rats - mice) in the transmission of this illness. Inside my activity I have been able to appreciate a high presence of rodents in hatcheries affecting and contaminating the balanced food, and sometimes destroying the facilities.
Muchas thank you.

Gracias.

Patricia: When one speaks of swinish cholera, it is necessary to have much care with what is made, since is an illness viral highly transferable infectocontagiosa, and that it can cause disastrous economic losses. You should keep in mind that the use of polluted meat is a favorable road for the propagation of the virus:
Transmission:
* I contact direct among animals (secretions, excretions, semen, blood).
* Spread by people that enter in the exploitations, veterinarians, etc.
* I contact indirect through the local, tools, the vehicles, the clothes, the instruments and the needles.
* Distribution to the pigs of foods with the help of insufficiently cooked waste.
* Infection transplacentaria (vertical): it can cause litters of reduced size, embryonic death, you raise with malformaciones and others end up being born weak, they will be able to be reservorios and to diffuse the virus to the susceptible animals.
On the other hand, the virus is quite resistant to the means, it is destroyed to a temperature of 56 º C in few minutes, it remains viable in residual waters 24 h. In manure, of 2 to 4 days. It persists in the blood and ganglion for many days. It resists a lot of time in the bony marrow. It is not destroyed in the refrigerated cadavers. He/she survives the smoky of the hams (85 days). The bacon still of 27 days of preparation it produces the illness. In frozen meats, it conserves their capacity infectante during 95 days. As you will be able to yourself to give bill, it is not advisable the use of the polluted meats neither in the industry neither it stops personal consumption.
Greetings.
