The global Equine Rabies Immunoglobulin (ERIG) market is seeing increased attention from healthcare professionals, manufacturers, and stakeholders due to its pivotal role in preventing rabies transmission following exposure. This article dives deep into the ERIG market’s current landscape, including growth drivers, key players, technological advancements, and the regulatory environment. With rabies being a highly fatal disease, especially in developing regions, understanding the intricacies of ERIG’s role and its evolving market dynamics is essential. Let’s explore how ERIG is shaping public health responses and the factors influencing its widespread use.
The Critical Role of Equine Rabies Immunoglobulin (ERIG) in Rabies Treatment
Rabies, a viral disease caused by the Rabies lyssavirus, remains one of the most dangerous zoonotic diseases, with a mortality rate of nearly 100% once clinical symptoms appear. Rabies is transmitted mainly through the saliva of infected animals, such as dogs, bats, and other mammals, through bites or scratches. When untreated, rabies invariably leads to death, often by paralysis or respiratory failure.
One of the primary treatments for rabies exposure is the administration of rabies post-exposure prophylaxis (PEP), which typically consists of a combination of rabies vaccine and rabies immunoglobulin (RIG). Equine Rabies Immunoglobulin (ERIG) is one such RIG derived from the serum of horses that have been immunized against rabies. ERIG is administered to individuals who have been exposed to rabies, enhancing the body’s immune response and providing immediate passive immunity until the body can build its own defenses against the virus.
