Following this, key recommendations were reached at the end of the meeting:

1. States to identify priority disease areas and involve partners in utilising parallel program resources for IDSR

2. Advocacy to executives at State and LGA levels should be instituted and maintained for the prompt release of funds

3. States should ensure a budget line and prompt release of funds for surveillance activities, taking full ownership

4. States should identify, designate and equip isolation/treatment centres for infectious diseases

5. Regular after-action review meetings and simulations should be conducted in all states and the FCT

6. States should ensure all health facilities (Public and private) report priority diseases to the LGA DSNOs.

7. States should set up a functional Emergency Operations Centre (EOC) with clear roles and responsibilities

8. NCDC should define the minimum standard requirements for State Epidemiologists, State and LGA DSNOs in Nigeria and also find resources required to achieve this standard

9. Enrollment of Laboratories across states into strengthening Laboratory management accreditation and training on biosecurity/biosafety

10. Training of personnel SLMTA and QMS, ISO 15189 and copies should be distributed to States
