Topic Overview

Hantaviruses are found in the saliva, urine, and droppings of
infected rodents, which show no signs of illness.

In the United States, at least four hantaviruses are known to cause
hantavirus pulmonary syndrome (HPS). Each hantavirus
is carried by a specific rodent:

  • Sin Nombre virus (SNV) is carried by the deer
    mouse and is found throughout North America. SNV causes the majority of HPS
    cases in the U.S.
  • New York virus is carried by the white-footed
    mouse and is found mostly in southern New England and the mid-Atlantic,
    southern, midwestern, and western states.
  • Bayou virus is carried
    by the rice rat and is found mostly in Louisiana and Texas.
  • Black
    Creek Canal virus is carried by the cotton rat and is found mostly in
    Florida.

Other rodents may carry hantaviruses, but they have not been
identified. Also, other related viruses cause a spectrum of diseases
called hemorrhagic fever with renal syndrome (HFRS). Many of the first symptoms
of HFRS resemble hantavirus pulmonary syndrome. But the later symptoms of HFRS
may include high fever, kidney failure, and bleeding disorders.
