Myxomatosis (sometimes shortened to "myxi" or "myxo") is a disease which affects rabbits. It is caused by the Myxoma virus. First observed in Uruguay in the late 1800s. It was introduced illegally to Egypt in 1842 and as a result spread to the rest of Africa. It was deliberately introduced into Australia in 1950 in an attempt to control rabbit infestation and population there; see rabbits in Australia. It was also deliberately introduced in the UK to try and reduce the rabbit population after World War II.
The practice was introduced in the 1920s and had gained widespread acceptance by the 1950s
