WHO declares Ebola emergency: Why Ebola is deadly, how it attacks you

The World Health Organization (WHO) declared the ongoing Ebola outbreak in Congo and Uganda a Public Health Emergency of International Concern, highlighting the urgency of the Bundibugyo strain—a rare but deadly variant. While only a handful of lab-confirmed cases have been officially reported, dozens of deaths under investigation near the Congo-Uganda border suggest the virus may have circulated undetected for weeks. The Bundibugyo strain is less studied than the Zaire strain, which caused West Africa’s 2014–2016 outbreak, but experts describe it as one of the most aggressive viral infections known. Dr. Rohit Garg, an infectious disease specialist, explains that Ebola attacks multiple organ systems simultaneously, triggering an extreme inflammatory response that damages blood vessels and immune cells. This leads to internal bleeding, fluid loss, and multi-organ failure within days, affecting the liver, kidneys, gastrointestinal tract, and brain. Unlike respiratory viruses such as COVID-19, Ebola spreads through direct contact with infected bodily fluids, including blood, saliva, vomit, and sweat, or contaminated medical equipment. The virus disrupts clotting mechanisms, causing uncontrollable bleeding from the nose, gums, or injection sites, while severe dehydration and septic shock push the body toward collapse. Early symptoms—fever, weakness, and muscle pain—often mimic common infections before rapidly worsening into vomiting, diarrhea, and neurological deterioration. Healthcare worker infections in the current outbreak serve as a critical warning sign, indicating gaps in infection-control systems. Dr. Garg notes that such cases increase the risk of hospital-based transmission, amplifying the outbreak’s spread. The WHO’s emergency declaration underscores the need for rapid containment, as the virus’s silent circulation and aggressive nature pose a growing global threat. Public health officials are monitoring the situation closely, emphasizing the importance of isolating cases, enforcing strict hygiene protocols, and strengthening healthcare infrastructure in affected regions. The outbreak’s trajectory remains uncertain, but experts stress that early detection and coordinated response efforts are essential to preventing further escalation.
