An
epidemic
is a
disease
that spreads over a large area and affects many people at the same time. Epidemics are when a disease spreads from person to person faster than
doctors
can control. If the disease spreads over the whole
world
, sometimes it is called a
pandemic
.
Such diseases must be treated quickly and properly otherwise they can infect people on large scale and pose a danger to the world. It is very important that timely
vaccination
and
treatment
is provided. The study of epidemics is part of
