The phrase ‘Zoonosis’ is a Greek word that comes from zoon (which means animal) and osis (which means ill). Zoonoses (plural: zoonosis) therefore, are animal diseases transmissible to humans. Zoonotic infections which can also be called zoonosis are diseases/infections caused by pathogens that can be passed or shared between humans and animals. They are diseases […]

Epidemiology
Statistically, the measures and/or determination of disease occurrence in a given population are usually expressed practically as rates or fractions which are stated as per the number of people in the population (for example 10, 100, and 10,000). The fraction is generally expressed as a numerator (which is the number of persons with the disease)

Epidemiology
In describing the health status of any population, useful data (in terms of health-related issues) from members of the community are crucial to determining the disease agent, mode of transmission, key symptoms/syndrome, type of disease, control and the establishment and evaluation of interventional measures. Epidemiologist work with data and, epidemiological studies are exclusively based on

Epidemiology
Epidemiological data has immense benefit to the health of any people as well as their standard of living as it relates to their health. Results from epidemiological studies are used for health planning and the development of tangible public health set of rules that help a particular population to evade and contain infectious disease-causing microorganisms

Such drift or subtle changes in the antigenic surfaces of pathogens are a setback for most vaccination exercises because some vaccines have a short lifespan and, thus new forms of such vaccines must be produced and administered in order to confer a better protection against the antigen it is directed to. Both antigenic drift and

Statistics is a branch of mathematics that is concerned with the proper method of collecting, organizing, presenting, analyzing and interpretation of numerical data. It affords scientists (especially the epidemiologists) the knowledge of making good use of numbers (data) in their research undertakings. In statistics, data can be classified into two types: Primary data and Secondary

Epidemiology
Once a disease-causing microorganism (pathogen) gains entry into the body of a susceptible host, the pathogen will adhere or attach itself to specific receptors on the cell surfaces of the host. Upon successful invasion and binding, the microorganism will begin to release chemicals that will eventually attack the host cells. The pathogen (agent) factors includes

Herd immunity is a group resistance of a population against a particular disease and the spread of its disease-causing agent in the same population. It is a collective type of immunity that is demonstrated by a community against a particular pathogen and disease within the same environment. In herd immunity, there are a larger proportion
The characteristics of a disease are largely dependent on the relationship between the environment, the disease causing microorganism (pathogen) and a susceptible host. Health; it must be noted is a state of equilibrium or balance between susceptible host (the individual) and the agent (pathogenic microorganism). The features of host, environment, and agent (disease cause) are

Epidemiology
Experimental epidemiological study can also be referred to as clinical trials. It is an analytical epidemiological study that examines the role of some specific agents in the treatment or prevention of a particular disease in a population. An experimental epidemiological study usually involves two phases of study in terms of their design: experimental study for
