Clinical Signs and Symptoms

Fever, chills, rigors, and drenching sweats characterized patients' illness, in addition to headaches, myalgias, and photophobia. About 4 days later, a spotty, red nonpruritic rash developed on the torso. Spleen enlargement occurred in one patient. Both eventually recovered after a few weeks (29).

In pigs, mummified fetuses, stillborn piglets with arthrogryposis, craniofacial deformities such as brachygnathia, occasional fibrinous body cavity effusions, and pulmonary hypoplasia were found. Degeneration of the brain and spinal cord has been noted along with nonsuppurative myocarditis in some piglets (30).
