Place lobsters in the pot (head first), cover tightly, return to a boil as quickly as possible and start counting the time. Steam a lobster for 8 minutes per pound, for the first pound. Add 3 minutes per pound for each additional pound thereafter. See chart below for approximate cooking times. Regulate the heat if the froth starts to bubble over.
epidemic definition. A contagious disease that spreads rapidly and widely among the population in an area. Immunization and quarantine are two of the methods used to control an epidemic.
Endemic diseases are often confused with epidemics. However, an epidemic refers to an outbreak of a disease. An epidemic occurs when a disease is spreading through one or more populations. In contrast, an endemic disease is one that is constantly present in a group or geographic area. Pandemics are world wide epidemics. Under certain circumstances, an epidemic can lead to a disease becoming endemic. Endemic diseases are not always present at high levels.
