Context: The World Health Organization (WHO) declared the Ebola outbreak in the Democratic Republic of Congo (DRC) and Uganda a Public Health Emergency of International Concern (PHEIC). The declaration was made because the outbreak posed a serious public health risk and had the potential for international spread.

About Ebola

1. Ebola virus disease is a zoonotic disease that spreads from animals to humans.
2. The disease is caused by the Ebola virus.
3. Fruit bats and non-human primates are considered major carriers of the virus.
4. Ebola spreads between humans through direct contact with:

• Blood,
• Bodily fluids,
• Secretions,
• Contaminated surfaces.

About PHEIC

1. A PHEIC is the highest level of global health alert declared by the WHO under the International Health Regulations.
2. It is declared when a health emergency is serious, sudden, unusual, and capable of spreading across countries.
3. The declaration also calls for a coordinated global response to control the outbreak.

Reasons for Declaring Ebola a PHEIC

1. Cross-Border Spread

1. Ebola cases were reported in both the Democratic Republic of Congo and Uganda.
2. The movement of infected individuals increased the risk of international transmission.

2. High Fatality Rate

1. Ebola is a highly dangerous disease that can cause severe illness and death.
2. The outbreak recorded several confirmed and suspected deaths.

3. Serious Public Health Threat

1. The outbreak created pressure on the healthcare systems of affected countries.
2. Weak health infrastructure increased the risk of further spread.

4. Presence of Bundibugyo Strain

1. The outbreak was caused by the Bundibugyo ebolavirus strain.
2. This strain is one of the major Ebola virus variants responsible for outbreaks.

5. Need for International Coordination: WHO considered global cooperation necessary for surveillance, treatment, vaccination, and containment measures.

Impact of Ebola Outbreaks

1. Health Crisis

1. Ebola causes severe symptoms and has a high mortality rate.
2. Large outbreaks can overwhelm healthcare systems.

2. Social and Economic Disruption

1. Ebola outbreaks create fear, panic, and social stigma among people.
2. Trade, travel, and economic activities are negatively affected.

3. Threat to Global Health Security

1. International spread of Ebola can become a major global health emergency.
2. The West Africa outbreak of 2014–16 showed the devastating impact of Ebola.

Measures Taken to Contain the Outbreak

1. Rapid Isolation of Patients

1. Infected individuals are isolated quickly to prevent further transmission.
2. Early treatment improves survival chances.

2. Contact Tracing

1. Health authorities identify and monitor people who came in contact with infected patients.
2. Contact tracing helps break the chain of transmission.

3. Safe and Dignified Burials

1. Special burial protocols are followed because the virus can spread through dead bodies.
2. Safe burials reduce community transmission.

4. Vaccination

1. WHO is using approved Ebola vaccines through ring vaccination strategies.
2. Vaccines are provided to frontline workers and close contacts of infected persons.

5. Monoclonal Antibody Treatment

1. Monoclonal antibody treatments are being used to improve patient survival.
2. Early administration of treatment increases effectiveness.

6. Infection Prevention and Control

1. Strict infection-control measures are implemented in hospitals and health centres.
2. Healthcare workers are provided protective equipment and training.

7. Public Awareness and Social Mobilisation

1. Awareness campaigns are conducted to reduce stigma and encourage early reporting of symptoms.
2. Community participation is important for controlling the outbreak.

8. Surveillance and Laboratory Support

1. Disease surveillance systems are strengthened for early detection of cases.
2. Laboratory testing is expanded for faster diagnosis.

Conclusion: The WHO declaration of PHEIC reflects the seriousness of the Ebola outbreak and the risk of international spread. Effective surveillance, rapid response, vaccination, public awareness, and international cooperation are essential to control Ebola outbreaks and protect global health security.
