👉 Epidemically refers to a situation where an outbreak of a contagious disease occurs unexpectedly, with no known cause or source. It is characterized by sudden onset, widespread illness, and death among a large number of people within a short period of time. This can be caused by various factors such as a high volume of travelers entering a new area, the spread of a virus from an infected individual to others through close contact, or natural disasters that disrupt normal human interactions.
