Ulceroglandular tularemia is the most common form of tularemia, a bacterial infection caused by Francisella tularensis.
Medical necessity is established by the presence of clinical symptoms and laboratory confirmation of Francisella tularensis infection.Treatment with antibiotics is medically necessary to prevent serious complications and potentially life-threatening outcomes associated with untreated tularemia.
The provider's responsibilities include obtaining a thorough patient history, conducting a physical examination, ordering and interpreting relevant laboratory tests (blood cultures, serological tests, PCR), making a diagnosis of ulceroglandular tularemia, prescribing appropriate antibiotic therapy, and educating the patient about disease prevention and infection control.
In simple words: Ulceroglandular tularemia, sometimes called deer fly fever, is a rare bacterial infection. You can get it from a tick or insect bite, touching an infected animal, or getting the bacteria in a cut. Symptoms include a skin sore, fever, chills, aches, and swollen lymph nodes.Doctors use antibiotics to treat it.
Ulceroglandular tularemia, also known as deer fly fever, is a zoonotic bacterial infection caused by Francisella tularensis.Transmission occurs through the bite of infected ticks or flying insects, direct contact with infected animals (often rodents or rabbits), or entry of the bacteria through cuts or sores after handling infected carcasses.The infection manifests with a skin ulcer at the site of inoculation, fever, chills, muscle and joint pain, sweats, and enlarged lymph nodes.Diagnosis is based on the patient's history, physical examination, and laboratory tests such as blood cultures, serological tests, and polymerase chain reaction (PCR) to identify antibodies. Treatment involves antibiotics like doxycycline, ciprofloxacin, streptomycin, or tetracycline.Education on preventative measures, including hand hygiene and safe handling of animals, is crucial.
Example 1: A hunter develops a skin ulcer and swollen lymph nodes after skinning a rabbit.Fever, chills, and body aches are present.The diagnosis of ulceroglandular tularemia is made after blood culture confirms the presence of Francisella tularensis., A child presents with a lesion and swollen lymph node following a tick bite while playing outdoors.Ulceroglandular tularemia is suspected clinically and confirmed with PCR testing. Doxycycline is prescribed., A patient with a history of handling carcasses of wild animals presents with fever, malaise, and lymphadenopathy.Following diagnostic tests confirming ulceroglandular tularemia, ciprofloxacin is initiated.
Complete medical history, including recent exposure to animals or insect bites.Physical examination findings documenting the presence of skin ulcer, lymphadenopathy, and systemic symptoms.Laboratory reports including positive blood culture, serological test results, or PCR results confirming the diagnosis of tularemia.
** Different forms of tularemia exist (glandular, oculoglandular, oropharyngeal, respiratory, and typhoidal), but A21.0 specifically addresses the ulceroglandular form.The severity of the illness and treatment approach will vary depending on the form and the patient's clinical presentation.
