eHA implements this project in collaboration with Ministry of Health and Sanitation (MoHS) to operationalize a 24 hr National call centre with a decentralized alert management system across 13 districts manned by district coordinators and operators.

Data analytics from the calls are pushed to the District Health Management Teams (DHMTs) in real time. In the event of an emergency/outbreak, the 117 also becomes a coordinating and logistics management connector between the public and the MOHS emergency response teams.


eHA's role

With guidance from the Ministry of Health and Sanitation (MOHS), eHA provides the programmatic, ICT, software and operational infrastructure of the 117 Alerts System, to enable timely reporting and response with surveillance and public health emergency preparedness/ response strategies.

eHA also provides both national and district level capacity building and mentorship support for surveillance and other public health personnel  for improved use of alerts information for decision-making.  
who benefits

Community Members, Ministry of Health and Sanitation, Government of Sierra Leone, Health sector and disease/emergency response stakeholders, researchers. The various groups will benefit from real time alerts and automated referral processes, and information garnered from data collection processes can provide evidence for decision-making processes.
