Countries with a high prevalence of infections with dengue, chikungunya, malaria etc., have a low occurrence of COVID-19 makes one to hypothesize that endemic infections may protect through interferon which retard subsequent illness/disease through viral interference (11, 12) . Previous experimental studies have revealed that beta coronaviruses are capable of inducing immune responses against one another by way of generating neutralizing antibodies which cross-react against other SARS-CoV viruses (15, 16) . Overall the organisms and individuals based on previous exposure to vaccines and infections come from the environment, internal sensors, memorized experience, and genome prefer to develop pathways in a goal-directed manner and improve the behavioural traits and phenotypic variability so as to protect and survive from infectious agents.
