Colorado tick fever (CTF), also known as Mountain tick fever or American mountain fever, is a viral disease caused by infection with the Colorado tick fever virus (CTFV), a member of the Coltivirus genera. CTF is transmitted to humans most commonly by the bite of an infected adult wood tick, and while there is no evidence of natural person-to-person transmission, rare cases of transmission by blood transfusion have been reported. The diagnosis of persons with CTF is complicated by non-specifi...
Colorado tick fever occurs primarily in the Rocky Mountain region of the western United States as well as the Canadian provinces of British Columbia and Alberta. More than 90% of all CTF cases in the United States are reported from Colorado, Utah and Montana. The disease is most prevalent during the summer months between April and August, and is usually limited to mountainous elevations between 1,200 and 3,000 meters. Patients with CTF are most often campers and young men, who have been expos...
Clinical manifestations of CTF can range from mild to life-threatening depending on the patient’s age and general health. The first symptoms of CTF usually occur 3-7 days after a tick bite, although the incubation period can be as long as 20 days. The initial symptoms of the disease often include fever, chills, headache, muscular and skeletal pain, and malaise. Other symptoms may include nausea, vomiting, stomach pain, light sensitivity and sore throat. About half of all patients experience a...
An initial diagnosis is based on the patient’s signs and symptoms and confirmation depends on laboratory testing. The appearance of a saddleback fever and the absence of a hemorrhagic rash common to Rocky Mountain spotted fever are clinical indicators of CTF. Leukopenia, a decrease in the number of circulating white blood cells, is the most common laboratory finding in CTF. The immunoflourescent staining of blood smears may be used to identify CTFV antigens, however a confirmed diagnosis can...
No specific treatment for CTF is available. Management of CTF includes treatment of fever and pain with analgesics and acetaminophen, along with standard infection control procedures. Patients infected with CTF should advise blood collection agencies of their illness prior to donation, due to the risk of transmitting CTF through blood transfusion.
- What Is Tularemia?
- Where Is Tularemia Prevalent?
Tularemia (also known as rabbit fever) is caused by oval-shaped bacteria (coccobacilli) called Francisella tularensis. F. tularensis is transmitted to humans by the bite of infected ticks, deer flies, contact with infected animals or infected carcasses, inhalation of air-borne bacteria, and ingestion of infected food or water. In the summer, most cases come from infected tick bites. In the winter, cases are reported by hunters who trap and skin infected animals. Person-to-person transmission...
Cases of tularemia have been reported across the United States with a concentration of reports in Missouri, Arkansas, and Oklahoma. From 1990 to 2000, there were 1,368 cases reported in the United States. On average, 124 cases per year were reported during this period of time. A cluster of cases were reported at Martha’s Vineyard (Massachusetts) in 2000. A study published by the journal Emerging Infectious Diseases showed that these cases were associated with landscaping work. Landscape worke...
Symptoms often appear abruptly three to five days after infection, but can take as long as two weeks to appear. A fever of 38°C to 40°C (100.4°F to 104°F) is the most common symptom. Other symptoms include joint pain, swelling of lymph nodes, headache, chills, dry cough, sore throat, ulcers at the site of infection, sore eyes, weakness, and diarrhea.There are several forms of tularemia, each specific to a particular route of entry by F. tularensis into the body. Ulceroglandular tularemia is t...
According to the CDC, a clinical diagnosis of F. tularensis can be confirmed by examining stained secretions, exudates, and biopsy specimens. The definitive confirmation of F. tularensis infection is growth of the bacteria in culture.
The CDC recommends intramuscular and intravenous antibiotic therapy for treatment of tularemia. A more detailed description of dosages recommended by the CDC can be found here. In summary, streptomycin is the recommended drug, with gentamicin serving as an alternative. The CDC recommends that these drugs be administered for 10 days. Both can be used in children and pregnant women.
