Plans and public healthcare policies formed globally are based on various aspects and impeding factors. Health policy comprises of goals, rules, and actions. These have an impact on the health challenges and priorities that transcend individual countries and regions (Brugha, Bruen, & Tangcharoensathien, 2014).

They may also reoccur from infectious diseases that may have occurred many years back. These infectious diseases are either new or have a potential to become epidemic in the near future. Some common examples of the EID include; HIV/AIDS, tuberculosis, Influenza, malaria, dengue, cholera, Ebola, and many others to name (Drotman et al., 2018).

Biostatistics in epidemiological studies, Epidemiological study for malaria, epidemiology, research and developmentQuantitative studies are those that rely on measures that can be represented by discrete numbers, such as age, weight or body temperature. Epidemiological studies too can be quantitative in nature. A quantitative epidemiological study can be broadly classified as ‘observational’ or ‘experimental’. It depends upon the extent of intervention by the researcher in the subject’s exposure or actions.
Biostatistics in epidemiological studies, epidemiologyIn the last few decades, after the discovery of penicillin, a large number of these diseases have been controlled or eliminated. However, infectious diseases have a tendency to recur in a different population or region than before. This phenomenon is termed as emerging infectious diseases (EID).

These models are based on previous trends of incidents and climate factors. Thus they allow for better prediction of disease incidents or outcomes.
Biostatistics in epidemiological studies, epidemiologyEpidemics of infectious diseases arise due to spread of the disease across individuals. It spreads within a geographical region over a period of time. When they spread at global level, it is referred to as pandemic. An infectious disease originates at a particular point.
