The latest victim is a 30-year-old woman from the town of Epuyén who died last night in a hospital where she was hospitalized for several days, the health ministry said.
Two other people are in intensive care and three in intermediate care, the ministry said.
Since last December 3, authorities have declared the health alert in the province, where 12 hantavirus infections have already been detected.
The Ministry of Health urged people to keep their homes well ventilated and clean, to use disinfectants and, in the case of camping, not to sleep in direct contact with the grass.
Hantavirus is transmitted to humans by mice infected with Hanta virus through contact with saliva, feces and urine.
Its symptoms are similar to those of an influenza: fever, muscle aches, nausea, vomiting and abdominal pain.
In humans, it causes hemorrhagic fever and severe pulmonary conditions.
