They can be caused by parasites, fungi, bacteria, or viruses, and many different animals may be involved in this type of infection, rodents included.

In this prodromal disease comes 2 or 3 weeks after the initial exposure to the virus.

Then, it disseminates to other parts of the body, and the prodrome symptoms start, usually with mild fever, chills, and muscle pain, also known as myalgia. These prodrome symptoms last 3 to 10 days and in this stage it is not possible to differentiate hantavirus from other infections.
