Morbillivirus is a type of
virus that causes serious disease in several species
of animals and in people. Distemper in dogs and rinderpest
in cattle are caused by different morbilliviruses.
Measles (rubeola) is a generally less severe morbillivirus-induced
disease of people, although this morbillivirus caused
many fatalities prior to the age of modern medicine.
An important feature of morbillviruses is their ability
to cause major epidemics when populations without immunity
are exposed. A large proportion of the canine population
died when canine distemper entered Europe 200 years
ago. Rinderpest, otherwise known as the "cattle plague",
has caused epidemics of biblical proportions. Furthermore,
one half to two thirds of the native population died
when measles was introduced into various areas of the
New World in the 1500s. There have been several major
die-offs among marine mammals caused by morbilliviruses
in recent years. Baikal seals in Lake Baikal (1987),
harbor seals in northwestern Europe (1988), and striped
dolphins in the Mediterranean Sea (1990) have all been
affected by separate morbillivirus epidemics. The National
Oceanographic and Atmospheric Association recently
implicated morbillivirus infection as the primary cause
of the 1987-1988 U. S. Atlantic coast bottlenose dolphin
die-off. In each of these events, thousands of animals
are believed to have died.
