"We still do not know.if this virus is the main virus that
causes MS", caution the Henles. "It is only a candidate".
Establishing
MS as an infectious disease poses a
basic question: Why do some people get MS while others,
perhaps
members of the same family do not? The answer may lie in the
discovery by the researchers that the blood of nurses and
relatives who tend MS patients carries an antibody
against
the
disease.
In East Africa, where MS is virtually unknown,
the
population in general has this same antibody in the blood,
indicating that the people were once infected but developed an
immunity.
Scientists know that MS follows certain
patterns.
It is, for example, more prevalent in temperate zones than in
tropical regions, and occurs in industrialized countries more
often than in underdeveloped
nations.
One theory is that in the less-developed
nations
the MS virus strikes almost all the population at an early age,
establishing a basic immunity.
These studies on MS antibodies suggest that the
virus
is much more widespread than the disease
itself and that MS may
occur only in individuals genetically or otherwise predisposed
to it.
