A98.4 Ebola virus disease

Name of the Condition

• Ebola virus disease (EVD)
• Also known as Ebola hemorrhagic fever.

Summary

• Ebola virus disease is a rare but severe viral illness that affects humans and nonhuman primates, characterized by fever, bleeding, and organ failure.

Causes

• Caused by infection with viruses within the genus Ebolavirus.
• Spread through direct contact with the bodily fluids of an infected person or via contaminated surfaces.

Risk Factors

• Living in or traveling to areas with known Ebola outbreaks, particularly in parts of Africa.
• Health care workers and family members caring for infected individuals without proper protective measures.

Symptoms

• Initial symptoms include fever, fatigue, muscle pain, headache, and sore throat.
• Progresses to vomiting, diarrhea, rash, impaired kidney and liver function, and in some cases, internal and external bleeding.

Diagnosis

• Laboratory tests such as ELISA (enzyme-linked immunosorbent assay), PCR (polymerase chain reaction), and virus isolation help confirm Ebola infection.

Treatment Options

• No specific antiviral treatment available, but supportive care is critical.
• Includes rehydration with fluids, treatment of specific symptoms, and experimental treatments such as monoclonal antibodies.

Prognosis and Follow-Up

• Prognosis varies; early supportive care with rehydration and symptomatic treatment improves survival.
• Regular monitoring and supportive care are crucial during recovery stages.

Complications

• Can include severe dehydration, multi-organ failure, and death.
• Survivors may experience ongoing health issues like fatigue, joint pain, and vision problems.

Lifestyle & Prevention

• Essential to avoid exposure to the virus by practicing good hygiene and using protective gear.
• Routine handwashing and avoiding contact with bodily fluids of infected individuals can reduce risk.
• Vaccination is available for high-risk populations.

When to Seek Professional Help

• Immediate medical attention is needed if experiencing symptoms after potential exposure, especially following travel to regions with known outbreaks.

Additional Resources

• World Health Organization (WHO)
• Centers for Disease Control and Prevention (CDC)
• Médecins Sans Frontières (MSF) for patient support and outbreak information.

Tips for Medical Coders

• Ensure accuracy by verifying patient travel history and contact with infected individuals when coding EVD.
• Common errors include misclassifying the symptoms under general viral infections without recognizing specific exposure risk factors.
