Symptoms
Some people with FMD have no symptoms. Even without symptoms, FMD can lead to serious, potentially life-threatening complications. It can cause disease of the arteries that supply blood to the kidneys and brain. Some complications of FMD include:
Causes
Fibrous cells are less strong and also less flexible. This change in composition of the arteries leads to their becoming stiffer and more prone to damage. FMD can lead to high blood pressure, stenosis, aneurysm and sometimes dissection of arteries.
Prevention
Epidemics of FMD have resulted in the slaughter of millions of animals, despite this being a frequently nonfatal disease for adult animals (2–5% mortality), though young animals can have a high mortality. The Taiwan outbreak that affected only pigs also showed a high mortality for adults.
Complications
Because FMD rarely infects humans, but spreads rapidly among animals, it is a much greater threat to the agriculture industry than to human health. Farmers around the world can lose enormous amounts of money during a foot-and-mouth epizootic, when large numbers of animals are destroyed, and revenues from milk and meat production go down.

Does FMD get worse over time?
In general, it is thought that FMD is not a rapidly progressive disease. This means that for most patients, the disease and its symptoms do not tend to worsen over time.

How can FMD be spread to pigs?
Also, pigs are particularly vulnerable to infection through the oral route. It has been demonstrated experimentally that FMD can be spread to pigs when they eat commercial feed products contaminated by the FMD virus. Also, the virus can remain active for extended periods of time in certain feed ingredients, especially soybean meal. Feed biosecurity practices have become an important area of study since a 2013 outbreak of Porcine Epidemic Diarrhea Virus (PEDV) in the US, thought to be introduced through contaminated feed.
Where is the FMD outbreak?
In April 2005, an Asia-1 strain of FMD appeared in the eastern provinces of Shandong and Jiangsu. During April and May, it spread to suburban Beijing, the northern province of Hebei, and the Xinjiang autonomous region in northwest China. On 13 May, China reported the FMD outbreak to the World Health Organization and the OIE. This was the first time China has publicly admitted to having FMD. China is still reporting FMD outbreaks. In 2007, reports filed with the OIE documented new or ongoing outbreaks in the provinces of Gansu, Qinghai and Xinjiang. This included reports of domestic yak showing signs of infection. FMD is endemic in pastoral regions of China from Heilongjiang Province in the northeast to Sichuan Province and the Tibetan Autonomous region in the southwest. Chinese domestic media reports often use a euphemism "Disease Number Five" (五号病 wǔhàobìng) rather than FMD in reports because of the sensitivity of the FMD issue. In March 2010, Southern Rural News ( Nanfang Nongcunbao ), in an article "Breaking the Hoof and Mouth Disease Taboo", noted that FMD has long been covered up in China by referring to it that way. FMD is also called canker (口疮, literally "mouth ulcers" kǒuchuāng) or hoof jaundice (蹄癀 tíhuáng) in China, so information on FMD in China can be found online using those words as search terms. One can find online many provincial orders and regulations on FMD control antedating China's acknowledgment that the disease existed in China, for example Guangxi Zhuang Autonomous Region 1991 regulation on preventing the spread of Disease No.5.
How long does it take for a ruminant to recover from FMD?
The incubation period for FMD virus has a range between one and 12 days. The disease is characterized by high fever that declines rapidly after two to three days, blisters inside the mouth that lead to excessive secretion of stringy or foamy saliva and to drooling, and blisters on the feet that may rupture and cause lameness. Adult animals may suffer weight loss from which they do not recover for several months, as well as swelling in the testicles of mature males, and cows' milk production can decline significantly. Though most animals eventually recover from FMD, the disease can lead to myocarditis (inflammation of the heart muscle) and death, especially in newborn animals. Some infected ruminants remain asymptomatic carriers, but they nonetheless carry the virus and may be able to transmit it to others. Pigs cannot serve as asymptomatic carriers.
