Infection was more likely to reach us via dirty boots, on a truck or in meat or dairy products carrying the virus. The organism is an aphthovirus and its family is Picorna viridae. There are dozens of subtypes, some more virulent than others. Reports have suggested this outbreak is a virulent Asia 1 or O serotype. It affects cattle, pigs, goats, sheep and deer but not other animals such as dogs, cats or horses.
Infection is caused from inhaling or eating virus particles - only a small amount is needed.
The disease very seldom has any effect on humans. Acid or alkali conditions kill the virus, so weak citric acid solution and washing soda, sodium carbonate, are often used to disinfect shoes, boots and vehicles transporting animals.
