The American dog tick (Dermacentor variabilis) is a common tick found in the United States. It is a vector for several diseases, including Rocky Mountain spotted fever (RMSF), tularemia, and ehrlichiosis. Rocky Mountain spotted fever is a serious illness that can be fatal if not treated. Symptoms include fever, headache, muscle pain, and a rash. The rash usually appears 2-4 days after the onset of fever. RMSF is treated with antibiotics. Tularemia is a bacterial infection that can cause fever, chills, headache, muscle pain, and swollen lymph nodes. In some cases, tularemia can also cause pneumonia or eye infection. Tularemia is treated with antibiotics. Ehrlichiosis is a tick-borne illness that can affect both humans and animals. There are two main types of ehrlichiosis: human monocytic ehrlichiosis (HME) and human granulocytic ehrlichiosis (HGE). Symptoms of HME and HGE can be similar to those of RMSF, but they are usually milder. Ehrlichiosis is treated with antibiotics.
