Article excerpts about the
causes of Arenaviruses:
Viral Hemorrhagic Fevers: DVRD (Excerpt)
Each of these families share a number of
- They are all RNA viruses, and all are
covered, or enveloped, in a fatty (lipid) coating.
- Their survival is dependent on an animal or
insect host, called the natural reservoir.
- The viruses are geographically restricted to
the areas where their host species live.
- Humans are not the natural reservoir for any
of these viruses. Humans are infected when they come into contact with infected hosts.
However, with some viruses, after the accidental transmission from the host, humans can
transmit the virus to one another.
- Human cases or outbreaks of hemorrhagic
fevers caused by these viruses occur sporadically and irregularly. The occurrence of
outbreaks cannot be easily predicted.
- With a few noteworthy exceptions, there is
no cure or established drug treatment for VHFs.

Arenaviridae: DVRD (Excerpt)
These viruses are zoonotic, meaning that,
in nature, they are found in animals. Each virus is associated with either one species or
a few closely related rodents, which constitute the virus natural reservoir.
Tacaribe complex viruses are generally associated with the New World rats and mice (family
Muridae, subfamily Sigmodontinae). The LCM/Lassa complex viruses are associated with the
Old World rats and mice (family Muridae, subfamily Murinae). Taken together, these types
of rodents are located across the greater proportion of the earths land mass,
including Europe, Asia, Africa, and the Americas. One notable exception is Tacaribe virus,
found in Trinidad, which was isolated from a bat. (Source: excerpt from Arenaviridae: DVRD)
