What was discovered

In 1958 the arenavirus that causes Argentine haemorrhagic fever, or 'mal de los rastrojos', was isolated; it is transmitted by field rodents (Calomys musculinus) to maize harvesters. It was identified after outbreaks from 1953 in north-western Buenos Aires province.

A team from the Ministry of Social Assistance and Public Health led by Parodi published the isolation in 1958; the disease had been recognised clinically since 1953.
