ABSTRACT
- Dr David L Heymann of World Health
Organization says that monkeys
experimentally infected with new coronavirus
have developed illness similar to mysterious
human respiratory disease SARS and that it
is now almost certain that coronavirus
causes disease; verifying cause of SARS is
essential for development of reliable
diagnostic tests to determine who has
disease so that affected patients can be
treated in isolation and those who are not
affected can carry on with their normal
activities; photo (M) Monkeys experimentally
infected with a new coronavirus have
developed an illness similar to the
mysterious human respiratory disease SARS,
and it is now almost certain that the
coronavirus causes the disease, a World
Health Organization official said here
today.
Dr. David L. Heymann, executive director
in charge of communicable diseases for
W.H.O., said the agency ''is 99 percent
sure'' that SARS is caused by the new
coronavirus based on the monkey experiments
in the Netherlands. Experiments on animals
are necessary because the lack of an
effective treatment for SARS and the
relatively high death rate make it unethical
to conduct such experiments on humans.
