Epidemiological data on infection outbreaks are challenging to analyze, despite improved control interventions Ebola virus Disease (EVD) remains a serious risk in Guinea (West Africa) with 607 reported cases and 406 deaths recorded (66.8%) as of 20th August, 2014.In this study we use modified epidemiological modeling SEIR to analyze data from an Ebola outbreak in Guinea from 22nd march – 20th August,2014 We use Bayesian inference with non – linear transmission times incorporated into augmented dataset as latent variables. Despite the lack of detailed data, most data sets record the time on symptom onset but transmission time is not observable. We inferred from such dataset records using structured Hidden Markov Models HMMS. Infectivity is determined before and after public health interventions for hospitalized cases. We estimate the number of secondary cases generated by an index case in the absence of control interventions (Ro). Our estimate of Ro is 1.57 (CI95 0.82-1.92) and the mean value of estimated detection rate is 0.75 (CI95 0.59 -0.93) with a coefficient of correlation between 𝛽 and v as – 0.23. We perform sensitivity analysis of the final epidemic size tothe time of intervention, which ensures the uniqueness and the global stability of the positive endemic equilibrium state.

ARTICLE: Before the year 2007, Nigerian government has been managing unprofitable contractual situations, most of which lacked the needed value for money. Some of which also were negative due to the very little monitoring habit that coursed general project abandonment for which in a general view those projects had suffered a great setback in terms of quality and sustainability. Furthermore, the government had made series of efforts trying to subdue these impending problems during which ample consultations were made; many programmes were designed in the bid to stop the menace. However, it was in the course of this that in the year 2007 the government came up with an agency that was shouldered with responsibility of checkmating these issues to appropriately monitor the quality of jobs being done and making sure that such works were actually captured in the year’s budget and therefore executing them accordingly. The government witnessed a tremendous achievement with this effort and thereby felt the need to improve on it and then transformed it into a well-organized outfit with autonomous control over all MDAs in the case of contract execution. This giant step has helped the Universal Basic Education Board to also have the long needed control over their numerous contracts across the country. It brought a great sanity into their ways of engagement concerning every contract process putting in mind the now introduced procurement law. The Universal Basic Education Board has therefore adopted all necessary medium in their ways of conducting all contract proceedings adhering with the procurement law put in place. The daring need therefore to completely abolish all past errors brought the need to adopt and practice the present procurement processes. Therefore, the extent of achievements of these processes needed to be abreast which in turn brought the need for the procurement process of the Universal Basic Education Board. It is very important that all parties must be satisfied with the quality of the project as well as timely payment by the client if satisfied for the overall performance. It is recommended that the pre-qualification process should be supported by laws which will guide against the people that might try to hijack the process. The whole process should be overhaul to avoid those who will try to use power in trying force professionals or official assign in carrying out the pre-qualification task.
