Ebola Virus Disease (EVD): Health Risks, and Prevention Measures

Ebola Virus Disease (EVD) is a severe, fatal illness affecting humans and non-human primates. The disease is caused by infection with viruses belonging to the genus Ebolavirus, family Filoviridae. Ebola has remained a significant public health concern, particularly in Central and West Africa. Cause and Transmission Ebola is transmitted to humans through close contact with the blood, secretions, organs, or other bodily fluids of infected animals such as fruit bats, chimpanzees, gorillas, monkeys, and forest antelope. Human-to-human transmission occurs through direct contact with: • Blood or bodily fluids of an infected person • Contaminated surfaces and medical equipment • Infected tissues during burial ceremonies • Needlestick injuries in healthcare settings The virus does not spread through the air like influenza or COVID-19. Signs and Symptoms Symptoms typically appear 2 to 21 days after exposure and may include: • Sudden onset of fever • Severe headache • Muscle and joint pain • Weakness and fatigue • Sore throat • Vomiting and diarrhea • Abdominal pain • Unexplained bleeding or bruising • Internal and external hemorrhage in severe cases Diagnosis: • RT-PCR (Reverse Transcriptase Polymerase Chain Reaction) • Antigen detection tests • Antibody testing • Virus isolation techniques Treatment • Early supportive care • Intravenous fluid replacement • Electrolyte management • Oxygen therapy • Treatment of secondary infections • Monoclonal antibody therapies approved for specific Ebola strains Prompt medical attention substantially increases survival chances. Prevention and Control Measures Preventive strategies include: Personal Protection • Frequent hand hygiene • Avoiding contact with infected individuals • Use of Personal Protective Equipment (PPE) • Safe handling of blood and bodily fluids Healthcare Facility Measures • Strict infection prevention protocols • Isolation of suspected cases • Proper sterilization of medical equipment • Safe biomedical waste disposal Community Measures • Public awareness campaigns • Safe burial practices • Contact tracing and monitoring • Vaccination programs in outbreak regions

Occupational Health Perspective Organizations operating in healthcare, humanitarian services, mining, oil & gas, shipping, aviation, and international travel sectors should maintain: • Infectious disease response plans • Employee health awareness programs • Travel health risk assessments • Emergency medical preparedness protocols • PPE training and infection-control education Conclusion Ebola Virus Disease remains one of the world's most serious infectious diseases due to its high mortality rate and outbreak potential. Continued surveillance, vaccination efforts, public awareness, and strong healthcare systems are critical to preventing future outbreaks and protecting global health security.
