The second wave of FMD

OA show ('918 '); [the second wave of foot-and-mouth disease] although the British Minister of agriculture once said that the foot-and-mouth disease in the territory had been effectively controlled, the detailed measures he later released caused new panic to the public and may lead to the arrival of the second wave of foot-and-mouth disease Over time, people have questioned the government's simple killing measures In fact, the government played a role of "chaser" from the beginning of the whole event The first cases were found two or three weeks ago, and then through market trading, the virus spread to neighboring farms When people learned about this, a nationwide ban had been introduced It is clear that the government wants to keep the virus under control in the existing limited area and not continue to spread, and the transaction records of livestock will show their exact source It is expected that in two weeks, all cases within the epidemic area will be confirmed, so that the momentum of re transmission of the virus can be strangled in the cradle The severe ban may have played a role in controlling the spread, but unfortunately, it also covers most of the country's major livestock producing areas, with predictable losses Two weeks ago, a group of infected sheep crossed northern England, heading south to a ranch in Devon Then the ranchers sent them to various areas in southern England, passing four livestock auction stores along the way The route was soon traced and cases of foot-and-mouth disease were found in most areas along the route Surprisingly, despite strict quarantine and prevention, the same disease was found in the South four days after the first patient in the northwest After the event, it was analyzed that the livestock auction house may have provided a channel for infection In addition, some businessmen negotiated the transactions by phone If these transactions cannot be recorded, then the government cannot trace the source from the records Therefore, veterinarians can only rely on those businessmen to consciously provide them with information about the infection Whatever the reason, these phenomena show that some people are reluctant to record their transactions, and the veterinarian can only wait And usually when these people come to the door, it means that the epidemic has started a new round of transmission Although more than half of the rural areas in the UK have foot-and-mouth disease, half of the cases are reported from livestock markets in two neighbouring countries However, due to the lack of complete and accurate livestock records, there is still no guarantee that there will be no possibility of infection in other places Now people's foresight is how to identify the disease of open grazing herds This type of grazing will cause the virus to spread to other areas far away before it is confirmed that there are patients Devon and some western villages have high livestock density, which means there are many opportunities for the virus to spread again In contrast, most of eastern England and Scotland are safe, where foot-and-mouth disease has also broken out, but the momentum is well controlled In the face of this complex situation, the British government is taking new measures An action plan called "fire break" has been adopted, that is, once cases are found, sheep and pigs within three kilometers will be slaughtered But in the northwest, this measure may encounter a lot of artificial resistance Although the number of livestock involved in the FMD disaster is less than 0.5% of the total, compared with the outbreak in 1967, the number of livestock slaughtered has increased significantly It's no wonder that people can't help asking questions about the results of 30 years of research and development on measures to control the epidemic As we all know, foot-and-mouth disease is difficult to control once it begins to attack Its impact is long-term, and more complex international relations will follow Human demand for early detection of the disease will continue to grow China feed industry information network te6 (author:)
