Foot and mouth disease protein. Computer artwork of a protein from the foot and mouth disease virus. The protein is coloured to show its folded structure, composed of beta sheets (green, flat), alpha helices (red spirals) and linking regions (orange). The virus causes foot and mouth disease in cloven-hooved animals. Symptoms include a fever and the development of blisters on the feet and in the mouth. It is highly contagious, spreading by contact with infected animals and animal products, in the air and on materials exposed to infection. The rapid spread of the disease can cause epidemics, requiring quarantining and slaughter of infected animals.
