In the last two years, Nigeria has experienced outbreaks of Lassa fever, Monkeypox, Cerebrospinal meningitis, cholera and a resurgence of yellow fever. During some of these outbreaks notably of Lassa fever, there have been reports of health care worker infections.
This has further highlighted the need for health care workers to adhere strictly to infection prevention and control (IPC) practices to keep themselves and their patients safe.
IPC is a universally relevant component of all health systems and promotes the health and safety of both people who use services and those who provide them. Effective IPC is a key determinant of the quality of health service delivery to achieve people-centered, integrated universal health coverage (World Health Organization, 2016).
The Nigeria Centre for Disease Control in delivering its mandate to protect the health of Nigerians, is collaborating with the Robert Koch institute of Germany, Deutsche Gesellschaft fÃ¼r Internationale Zusammenarbeit (GIZ)in the â€˜MAURICEâ€™ IPC Project. This project aims at prevention of healthcare acquired infections among health care workers in Nigeria.
This is coordinated by NCDC and a technical working group comprising of national IPC stakeholders with the primary objective to develop a harmonised national IPC manual for all personnel working in health care setting. In addition, the project supports a â€˜training of trainersâ€™ workshop for frontline health care workers as â€˜IPC change agentsâ€™ using the participatory quality development approach (PQDA). In addition, quick reference IPC documents â€œone pagers and miniaturesâ€ (pocket hand book) on standard and transmission based precautions have been developed.
The IPC PQDA workshop was piloted in FCT university of Abuja teaching hospital and is currently being implemented in Lagos state where 28 health care workers from seven private and seven public facilities were trained as IPC change agents.
The PQDA model employs the â€œbottom top approachâ€ which promotes ownership by staff in a health care institution and leadership engagement for an IPC enabling environment with consequent sustainability of an IPC culture.
The achievements of the PQDA from the pilot and Lagos workshops have been remarkable with impressive feedback from both participants and the medical directors of the participating health facilities.
The significant improvement of infection prevention and control measures in the country will require a scale-up of the project across all states. The last phase of the project is currently ongoing and involves an operational research for the adequate step by step documentation of all the processes of the project implementation.
In a country like Nigeria where there is a high burden of infectious diseases, the responsibility should not be left to the government or health care workers alone to prevent infectious diseases. Adopting standard IPC measures such as a good hand hygiene into our daily routine can reduce deaths due to diarrheal diseases (e.g. cholera) by half, the risk of respiratory infections by 16% and prevent up to a million deaths annually. It is our collective responsibility to ensure a safer Nigeria through standard infection prevention and control.
By raising IPC Change Agents through the MAURICE Project, we are leading the change to create a healthier and safer Nigeria through the prevention and control of diseases of public health importance and strengthening our national health security.
SUMMARY OF REPORTS
In the reporting week ending on June 17, 2018:
o There were 116 new cases of Acute Flaccid Paralysis (AFP) reported. None was confirmed as Polio. The last reported case of Polio in Nigeria was in August 2016. Active case search for AFP is being intensified as Nigeria has reinvigorated its efforts at eradicating Polio.
o 725 suspected cases of Cholera were reported from 19 LGAs in eight States (Adamawa â€“ 80, Bauchi â€“ 323, Borno â€“ 2, Kaduna â€“ 1, Kano â€“ 42, Kogi â€“ 20, Plateau - 19 & Zamfara - 238). Of these, nine were laboratory confirmed and nine deaths were recorded.
o Six suspected cases of Lassa fever were reported from three LGAs in two States (Katsina â€“ 1 & Ondo â€“ 5) this reporting week. One was laboratory confirmed and no death was recorded.
o There were 19 suspected cases of Cerebrospinal Meningitis (CSM) reported from ten LGAs in four States (Kano â€“ 1, Katsina â€“ 12, Sokoto â€“ 1 & Yobe - 5). Of these, no was laboratory confirmed and no death was recorded.
o There were 188-suspected cases of Measles reported from 28 States. No laboratory-confirmed and no death was recorded.
In the reporting week, all States sent in their report except Akwa-Ibom, Cross River, Delta and Imo States.
