At a time when Rivers State continued to face recurring threats from infectious diseases such as Ebola Virus Disease, Lassa Fever, and COVID-19, Dr. Chidiebere Christopher Ajunwa emerged as one of the physicians helping to strengthen the State’s disease prevention, outbreak preparedness, and emergency-response capacity.

Recognizing that effective outbreak control depends on prevention, surveillance, and rapid intervention rather than treatment alone, Dr. Ajunwa dedicated much of his career to supporting infectious disease management initiatives across Rivers State. Through his work with the Rivers State Ministry of Health, Rivers State Hospital Management Board, and various emergency-response programs, he contributed to efforts aimed at protecting both healthcare workers and the general public from emerging infectious disease threats.

His activities extended across several Local Government Areas, including **Port Harcourt, Obio/Akpor, Okrika, Eleme, Ikwerre, Oyigbo, Khana, Gokana, Tai, and Ahoada East**, where public health preparedness, disease surveillance, infection prevention, and healthcare-facility readiness remained critical components of the State’s public health strategy.

During the 2014 Ebola Virus Disease outbreak, Rivers State became one of only two states in Nigeria to record confirmed Ebola cases. The outbreak created significant concern because of the potential for widespread transmission through community and healthcare settings. Dr. Ajunwa was among the physicians involved in outbreak-response activities designed to contain the disease and prevent further spread.

His responsibilities included patient management, infection prevention and control, healthcare-worker protection, contact tracing support, outbreak preparedness, and emergency-response coordination. Working alongside other healthcare professionals and public health officials, he helped implement measures that strengthened Rivers State’s ability to identify, isolate, monitor, and manage potential Ebola cases.

Beyond Ebola, Dr. Ajunwa continued to support infectious disease preparedness and response initiatives involving Lassa Fever and later the COVID-19 pandemic. During these public health emergencies, he contributed to healthcare-facility preparedness efforts, infection-control implementation, workforce training, and patient-management activities that enhanced the State’s response capacity.

One of the most significant aspects of his work involved strengthening infection-prevention practices among healthcare personnel. Through training, mentorship, and technical guidance, he helped improve adherence to infection-control protocols, reducing the risk of healthcare-associated transmission during disease outbreaks. His efforts supported the protection of frontline healthcare workers while helping healthcare facilities maintain continuity of essential services.

Public health officials noted that Dr. Ajunwa’s work complemented government efforts to improve epidemic preparedness by enhancing surveillance systems, promoting rapid-response capabilities, and strengthening healthcare-facility readiness. His involvement in emergency-response operations helped ensure that Rivers State remained better positioned to detect and respond to infectious disease threats before they escalated into larger public health crises.

The impact of these efforts became particularly evident during the COVID-19 pandemic, when healthcare systems worldwide faced unprecedented pressure. Through his contributions to infection prevention, healthcare-worker safety, patient management, and emergency preparedness, Dr. Ajunwa helped strengthen the resilience of Rivers State’s healthcare system during a period of extraordinary challenge.

Health-sector observers described his approach as an example of how physician-led public health interventions can strengthen epidemic preparedness and improve healthcare-system resilience. By emphasizing prevention, surveillance, workforce preparedness, and rapid response, Dr. Ajunwa demonstrated the importance of proactive public health measures in protecting communities from infectious disease threats.

His work continues to serve as a model for strengthening disease prevention and outbreak-response capacity across Nigeria, particularly in regions where emerging infectious diseases remain a persistent public health concern.
