Hepatitis c: causas, sintomas, tratamiento
Hepatitis C: Understanding the Virus and Treatment Options
Overview of Hepatitis C
- Hepatitis C is caused by a virus that differs from other types of hepatitis, with approximately 80% of infected individuals progressing to chronic infection.
- Many people remain asymptomatic until liver function tests reveal the presence of the virus in their blood, highlighting the importance of regular testing.
Transmission and Risk Factors
- The primary mode of transmission includes blood transfusions and potentially through sexual contact, particularly in cases involving bleeding.
- Healthcare workers, such as doctors who handle needles, are at higher risk for contracting hepatitis C due to potential needle-stick injuries.
- Intravenous drug users are also at significant risk because they often share needles; tattooing and piercing can pose similar risks if proper hygiene is not maintained.
Clinical Implications
- Hepatitis C can remain asymptomatic until severe liver failure occurs; early detection and treatment are crucial for better outcomes.
- A strong immune response may lead to spontaneous viral clearance in some patients, but most do not achieve this naturally.
Treatment Options
- Current treatments involve direct-acting antivirals (DAAs), which have shown high cure rates when administered early.
- There are various treatment regimens available targeting different genotypes (1 through 6), with specific combinations recommended for optimal effectiveness.
