Part A
In 2001 the United Kingdom was hit again by foot-and-mouth disease, the first time since the 1960s, causing a national crisis. However, much of the panic and confusion was spread largely as a result of ignorance of the disease.
Foot-and-mouth is a highly contagious(传染性的) disease found in Africa, South America, Asia, the Middle East and parts of Europe. It affects cloven-footed (偶蹄) domestic animals such as cows, pigs, sheep and goats, as well as wild animals like rats and deer and zoo animals such as elephants. Horses, however, cannot contract(感染) the disease.
It is very rare for humans to catch the disease Indeed, only one case has been recorded in Great Britain and that was in 1967.
Part B
Foot-and-mouth disease is insidious(潜伏的)and can be spread by direct or indirect contact with infected animal. The disease can be spread on the wind, and can also be spread by people, equipment or vehicles which have been in contact with the disease.
Although the authorities do not really know where this latest outbreak of the disease originated, it can enter a country in frozen meat imported from other countries where the disease is common. Unlike Mad Cow Disease (BSE) and the human equivalent CJD, foot-and-mouth has no implications(牵连) for the human food chain. Any meat, milk, cheese and other dairy products can be consumed quite safely.
Part C
It seems that the only way to contain the disease is to kill infected animals. There is no cure for the disease, and although adult animals normally recover in 2-3 weeks, they sadly remain carriers of the virus (病毒) for up to two years.
From the time the disease was first reported to the time the epidemic (流行) was officially declared over, one and a half million and more domestic animals were slaughtered and large areas of the countryside were closed to the public. These areas included parks, woods and forests, and various leisure attraction situated in the countryside.
