A68 Relapsing fevers

Name of the Condition

• Relapsing Fevers

Summary

Relapsing fevers are bacterial infections marked by recurring episodes of fever, headache, and muscle/joint pain. They are caused by Borrelia species transmitted via ticks or lice.

Causes

The condition results from infection with Borrelia bacteria. Transmission occurs through the bite of infected soft-bodied ticks or lice.

Risk Factors

• Exposure to tick or lice habitats, especially in endemic areas.
• Poor sanitation and crowded living conditions (increases lice-borne risk).

Symptoms

• Repeated episodes of high fever
• Chills and sweating
• Headache and muscle aches
• Nausea or vomiting
• Fatigue

Diagnosis

Diagnosis involves blood tests to identify Borrelia spirochetes, PCR/molecular tests for bacterial DNA, and physical exams assessing symptoms and exposure history.

Treatment Options

• Antibiotics (e.g., doxycycline, tetracycline) are standard.
• Antipyretics manage fever/aches.
• Hydration and rest support recovery.

Prognosis and Follow-Up

With timely antibiotics, prognosis is favorable. Follow-up may be needed to monitor for recurrence or complications.

Complications

• Severe cases can lead to organ damage (e.g., liver, heart).
• Neurological issues (e.g., meningitis) may occur in rare instances.

Lifestyle & Prevention

• Avoid tick/lice habitats; use protective clothing.
• Practice good hygiene to reduce lice exposure.
• Promptly remove ticks and seek care after bites.

When to Seek Professional Help

Seek care if fever recurs, symptoms worsen, or exposure to ticks/lice is suspected.

Tips for Medical Coders

Use A68 for general relapsing fevers. Specify type (e.g., tick-borne vs. louse-borne) if documented. Ensure clinical details align with coding guidelines.
