What are the symptoms of foot-and-mouth disease in cloven-hoofed animals? Can foot-and-mouth disease in pigs be transmitted to humans?

Foot-and-mouth disease, also known as "mouth-and-mouth ulcer", is an acute, febrile and highly contagious disease of cloven-hoofed animals caused by foot-and-mouth disease virus. Mainly against cloven-hoofed animals, occasionally seen in people and other animals, will never infect other livestock and chickens, ducks and other poultry. It is characterized by blisters in the oral mucosa, hooves and breast skin. The specific symptoms are as follows:

1. Sick cattle stand drooling, sick pigs can't afford to lie on the ground, sick sheep toe

2. Blisters appear in lips, tongue, gums, nose, heel, fork, breast and so on.

3. In the later stage of the disease, the blisters burst and scabbed, and in severe cases, the hoof shell fell off, and scars and new toenails could be seen during the recovery period.

4. foot-and-mouth disease spreads quickly, the incidence is high, the mortality rate of adult animals is low, young animals often die suddenly and the mortality rate is high, piglets often die in litters.

PS: will the foot-and-mouth disease of pigs be transmitted to humans?

Humans may suffer from foot-and-mouth disease through contact with infected animals, but this is rare. Because the foot-and-mouth disease virus is sensitive to stomach acid, humans do not usually get infected with the disease virus by eating meat. In the UK, foot-and-mouth disease was last confirmed in 1967. There are also very few cases of infection in continental Europe, Africa and South America. Symptoms of foot-and-mouth disease in humans include discomfort, fever, vomiting, red ulcers and decay of oral tissue (corrosive blisters on the surface), and occasional skin blisters. For humans, it is worth noting that this symptom is similar to that of another viral disease, commonly referred to as "hand, foot and mouth disease", which occurs more frequently in humans, especially in children; that disease is caused by another virus of the small RNA family, an enterovirus called Coxsackie A virus. Because foot-and-mouth disease rarely spreads to humans but spreads very quickly among animals, it is much more harmful to agriculture and animal husbandry than to human health. Farmers around the world can lose as much as $1 billion a year when foot-and-mouth disease spreads, leading to the destruction of large numbers of livestock and a huge reduction in income from milk and meat products.

Annex 2: foot-and-mouth disease is harmless to the human body, why do we continue to kill pigs?

The main reason why pig farms with foot-and-mouth disease must be culled is that the "foot-and-mouth disease" virus has spread rapidly, and there has been no outbreak of foot-and-mouth disease in Taiwan for at least 70 years, so none of the existing pigs have the ability to resist foot-and-mouth disease. Before the import quantity of foot-and-mouth disease vaccine can not be fully supplied to all pigs for injection. In order to protect other pig farms without foot-and-mouth disease from infection and suffer major economic losses, all pigs in diseased pig farms must be culled in order to reduce the spread of the virus and help control the epidemic.
