Special Editions

Epidemiology – Open Journal (EPOJ) is an online open access end-to-end portal that contains all epidemiological documentation.

Epidemiology is the study of the distribution and markers of health-related states and events (including but not limited to diseases) and the application of these studies to disease control on a large scale.

Openventio’s mission is to serve as an open access portal for all epidemiology professionals looking for a single source for descriptive studies and developments in this field.

Former Senior Lecturer – EPOJ


In obtaining publication for my article, I received excellent service from the EPOJ Editorial Office; it can only be described as exemplary. Every time there was any correspondence or a query, the Editorial Office assistants were helpful, polite, attentive and friendly. I also liked the procedure of EPOJ in obtaining opinions regarding the article; it was sent to three reviewers, anonymously, and their comments relayed (anonymously) to me, and when I had made corrections or incorporated those views, the process was repeated. I thought this was fair, even-handed and without bias. I would certainly recommend EPOJ to any colleagues or if I have another article I wish to have published. Thank you again EPOJ Editorial Office.

We really had a nice experience. The flexibility of submission of manuscripts via e-mail was very convenient especially from countries with poor internet service. The peer review process was speedy and efficient. The overall process from submission to decision is one of the fastest.
