“We have entered a pandemic era”, states a recent study in the journal ‘Cell’.
Recent epidemics and pandemics like COVID-19, SARS, MERS, H1N1, Zika virus, Ebola virus, HIV etc could indicate that we are headed towards a new phase of epidemiological transitions and re-emerging infectious diseases.
Epidemiological transition is a change in the disease patterns and the causes of death over a period of time. The concept was originally proposed by Abdel R. Omran who described the first three stages of it. Two more stages were subsequently added.
