Incubation Period

Streptobacillosis symptoms appear during 3-10 days following the exposure to infection, but sometimes can appear in 3 weeks only. By this time, wounds heal, and it gets harder to identify the reasons for disease. Sodoku symptoms occur in 1-3 weeks after bacteria invade human body. Generally, this type of illness requires more time to recover from, and symptoms disappear slower.

Rat Bite Fever Blood Test

The diagnosis of the disease usually consists of medical tests. Blood, skin, or mucus samples are usually examined. If streptobacillary bacteria need to be defined, living organisms are cultivated and observed. When doctors suspect spirillary fever, testing is done by direct visualization of organisms in blood smears. Blood antibody tests are also required.

Side Effects of Rat Bite Fever

After rat bite, instant first aid is necessary. If left untreated, diseases can be lethal. Mortality rate for Sodoku is 13%, and for Streptobacillosis – 10%. But even if a person survives, disease ignorance may lead to serious consequences including:

  1. Heart and heart valve infections (myocarditis, pericarditis or endocarditis).
  2. Meningitis and other brain infections.
