Abstract

Livestock’s health is crucial for countries’ economy as it serves as an important source of food. However, recent and old human history has witnessed many threats that impacted animal life with devastating consequences on human communities that depend on it. One of the most important causative agents for animal outbreaks is food-and-mouth disease (FMD) which is currently affecting many developing countries. Extensive records and database have been developed by many national and international organizations for this viral infection, In the present study an already established dataset will be analyzed using a unique perspective of applying statistical process control (SPC) tools that are commonly used in industry in monitoring, control and quantitative assessment of FMD outbreaks in selected countries in El Maghreb El Arabi with the aid of statistical software platforms. Two types of control charts (rare event and Laney attribute charts) were used in the outbreak analysis to show events-behavior and trend. Pareto, Pie, 3D diagrams and statistical analysis were used for data interpretation. Most of the outbreaks were started from Tunisia and spread to the upper coastal region in Algeria then propagated at a lower frequency to the south till altitude 31.87°N followed by Morocco adjacent to Casablanca. Most of cases were started, amplified and disseminated from the east of imaginary line 0.00°. Most of FMD incidences occurred in Algeria with late fewer incidents in Morocco with very limited geographical distribution. All cases of FMD were of serotype O diagnosed mostly by World Organization of Animal Health (OIE) with delay time between observation and report of events ranges from 3 to 123 days. Control charts showed intermittent significant excursions in assessed outbreak parameters, either in magnitude or time interval between events. Accordingly, incidents of outbreaks could be simply assessed quantitatively in timely manner using SPC tools.
