World Hepatitis Day: Free Vaccines, Testing, and the Cure That Changes Lives

28/07/2026 22:43 - Salud

A Date to Celebrate Life and Science

Every July 28th, the world comes together to commemorate World Hepatitis Day, an initiative driven by the World Health Organization (WHO) in 2008. Did you know why this date was chosen? It honors the birth of Professor Baruch Samuel Blumberg, the brilliant American scientist who discovered the Hepatitis B virus and was awarded the Nobel Prize in Medicine in 1976.

What are viral hepatitis?

Hepatitis is an inflammation of the liver caused by five main viruses: A, B, C, D, and E. Although they can be silent, they act with great affinity on liver tissue, altering cell function. The good news is that today we have extraordinary tools: prevention, testing, and treatment.

Types and Transmission
  • Hepatitis A and E: Transmitted through contaminated water or food (fecal-oral route). They generally cause acute infections and do not become chronic.
  • Hepatitis B: Contracted through contact with blood or from mother to child during childbirth. It can become chronic and lead to cirrhosis.
  • Hepatitis C: Transmitted mainly through infected blood (such as shared needles or old blood transfusions).
  • Hepatitis D: Has the particularity of only infecting people who already have Hepatitis B, worsening the clinical condition.
Warning Signs

Although it often does not present obvious symptoms, there are signs that should trigger an alert to act in time:

  • Jaundice: Yellowing of the skin and the whites of the eyes.
  • Dark urine: Tone similar to a cola drink or strong tea.
  • Pale stools: Clay-colored, grayish, or whitish deposits.
  • Abdominal pain in the upper right side, extreme fatigue, fever, nausea, or joint pain.

Prevention and Cure: It is Possible!

In Argentina, the vaccine against Hepatitis A has been administered to children since 2002, and the Hepatitis B vaccine is given to newborns in the maternity ward. Both are available free of charge in the national immunization schedule, which is the Argentine public health system's program ensuring free vaccines for all citizens. Furthermore, Hepatitis C now has medication that allows for a definitive cure! A simple blood test is, in most cases, the only way to detect the infection in time.
