World Hepatitis Day: Understanding Risks and Types
As the world marks World Hepatitis Day on 28th July, the spotlight shines on a silent yet deadly epidemic—viral hepatitis. Affecting more than 300 million individuals globally, it is responsible for over a million deaths each year. The campaign's current theme, 'Finding the Missing Millions', underscores the urgency of identifying those unknowingly living with this disease.
Hepatitis, an inflammation of the liver, manifests in several forms, primarily caused by viral infections. The most notorious among these is hepatitis C, a stealthy foe that can lurk in the body for decades without symptoms. Despite its covert nature, it is a leading cause of liver transplants and liver cancer worldwide.
Understanding the Variants
The hepatitis virus comes in five main types: A, B, C, D, and E. Hepatitis A and E are typically transmitted through contaminated food and water, often causing acute but self-limiting infections. In contrast, hepatitis B, C, and D are bloodborne, with B and C being the most prevalent and perilous.
Hepatitis B affects an estimated 240 million people globally and is preventable through vaccination. On the other hand, hepatitis C, which lacks a vaccine, is often spread through unsafe medical practices, blood transfusions, and intravenous drug use.
Who is Most at Risk?
While hepatitis can strike anyone, certain groups are more vulnerable. People who inject drugs, those who have received unscreened blood transfusions, and individuals living with HIV are at heightened risk. Moreover, healthcare workers and infants born to infected mothers also face significant exposure.
World Hepatitis Day serves as a crucial reminder of the need for increased testing and awareness. By identifying those infected early, we can mitigate the disease's impact and save lives. The global community is urged to step up efforts in prevention, testing, and treatment, ensuring that the 'missing millions' are found and supported.
