Top 10 Commonly Confused Words in Veterinary Epidemiology

Top 10 Commonly Confused Words in Veterinary Epidemiology 1. Prevalence vs. Incidence Prevalence refers to the total number of cases of a disease in a population at a specific time, while incidence represents the number of new cases within a defined period. Remember, prevalence is like a snapshot, while incidence is more like a video, capturing the new occurrences. 2. Endemic vs. Epidemic Endemic refers to the constant presence of a disease within a particular region or population. On the other hand, an epidemic occurs when there is a sudden increase in the number of cases, surpassing what is typically expected. Think of endemic as a steady stream and epidemic as a sudden surge. 3. Zoonosis vs. Anthroponosis Zoonosis refers to diseases that can be transmitted from animals to humans, like rabies. Anthroponosis, on the other hand, are diseases that primarily affect humans but can be transmitted to animals. Understanding these terms is vital for effective disease control strategies. 4. Outbreak vs. Cluster An outbreak is a sudden increase in the number of cases of a disease in a specific area or population. A cluster, on the other hand, refers to a group of cases that are closely related in terms of time and location. While all outbreaks are clusters, not all clusters are outbreaks. 5. Sensitivity vs. Specificity
