The outbreak of a new virus responsible for what is known
as severe acute respiratory syndrome (SARS) raises a number of
scientific, medical and social problems. Thanks in part to the
quick response and collaborative effort of a team of international
scientists, the virus has remained fairly well contained. However,
it has infected 7,000 people worldwide and has killed over 500.
It is still an enormous health risk in China, and there is still
the possibility of an international epidemic that would have devastating
consequences.
This is the second of two articles on the science and sociology
of SARS. The first article explained some of the scientific understanding
of viruses, and particularly the virus that causes SARS [see
The science and sociology of SARSPart
1: Viruses and the nature of present outbreak]. This
article will consider the social significance of the effort to
contain the disease.
By all accounts, the scientific effort that has gone into combating
SARS has been extraordinary. The outbreak is thought to date back
to November of last year. At the end of February 2003, the virus
had spread from China to Vietnam, where it infected 22 hospital
workers. It was not until March that the seriousness of the outbreak
became clear to international scientists. On March 12, the World
Health Organization (WHO) issued a global alert warning of a number
of cases in Asia of severe atypical pneumonia. After SARS continued
to spread, with no apparent treatment for those who came down
with the disease, the WHO increased the level of its global alert,
issuing a rare emergency travel advisory.
At that time, the cause was unknown, with suspicions that it
might be a variety of influenza. Within two weeks of the WHO global
health alert, the suspected cause of the disease was determined
to be a particularly virulent strain of the coronavirus. Within
two weeks of isolating the virus, the entire genetic sequence
and exact structure of the virus had been determined and is now
publicly available.
On April 16, the coronavirus was scientifically confirmed to
be the cause of SARS, after monkeys infected with the virus produced
the symptoms associated with the disease. This provided the fourth
of the so-called Koch postulates to determine the cause of an
infection: the virus must be found in all cases of the disease,
it must be isolated from the host and grown separately, it must
reproduce the disease when introduced in a non-infected host,
and it must be re-isolated from the newly infected host.
In contrast to this rapid pace of scientific understanding,
it took two years in the 1980s to identify HIV as the cause of
AIDS. This is not to disparage the enormous effort that has gone
into the understanding of AIDS. Rather, it is a testament to the
power of modern science.
With the identification and genetic sequencing of the coronavirus,
efforts can now be centered on working to develop vaccines and
more direct treatments for the disease. The rapidity of the WHO
response to the disease once it was known to be a serious threat
has prevented it, at least for the time being, from spreading
to the general population in countries such as Vietnam, Singapore
and Canada. SARS was originally introduced into these countries
by visitors from China, but new incidents of the disease are beginning
to fall, and in Vietnam have halted all together.
A product of international collaboration
The danger posed by the virus is very real. It continues to
spread throughout China, and undoubtedly many of the students
and workers who have returned home from Beijing and other major
cities in recent weeks have brought the virus with them. As the
virus spreads it will continue to killthe death rate is
now estimated at about 15 percent. It will have an especially
devastating effect if it spreads into Chinas large AIDS
population, which because of weakened immune systems will be even
less capable of surviving the disease.
The more the virus spreads, the greater the possibility that
it will entrench itself as a global disease. According to David
Heymann, executive director of WHOs communicable diseases
department, If the SARS virus maintains its present pathogenicity
and transmissibility, [it] could become the first severe new disease
of the twenty-first century with global epidemic potential. As
such, its clinical and epidemiological features, though poorly
understood, give cause for particular concern.
Most new diseases of the past century have had features that
limit their capacity to propagate. In contrast, SARS is
emerging in ways that suggest great potential for rapid international
spread under the favorable conditions created by a highly mobile,
closely interconnected world, said Heymann. If it develops
into a global disease, it is possible that it could become another
influenza-type problem, requiring constant monitoring to keep
up with rapid mutations and to develop new vaccines and treatments.
If the virus has spread thanks to the interactions of global
society (as the May 2 issue of Science noted, Infectious
diseases do not respect national boundaries), the process
of combating it has relied on these same forces. Every success
in combating the disease has relied on international collaboration,
while every block has been bound up with national competition
and narrow social interests.
Scientists around the world have been able to pool their respective
resources and expertise toward the unified aim of understanding
the disease. The effort, coordinated by the WHO, was described
by Heymann: These laboratory directors have put aside profit,
certainly prestige, and national pride to work together to help
put into the public domain the information that is so necessary
to learn about this disease. And it has been done in record time.
Karl Stöhr, a WHO virologist and coordinator of the WHOs
global network, echoed Heymanns remarks, noting in addition,
In this globalized world, such collaboration is the only
way forward in tackling emerging diseases.
The importance of global efforts in combating the disease have
been so clear that they have forced a token recognition from the
Bush administration in Congressional testimony of Tommy Thompson,
the secretary of health and human services, and Dr. Julie Gerberding,
director of the Centers for Disease Control and Prevention (CDC).
In her testimony, Gerberding noted, SARS also highlights
that US health and global health are inextricably linked and that
fulfilling CDCs domestic mission...requires global awareness
and collaboration with domestic and international partners to
prevent the emergence and spread of infectious diseases...SARS
presents a major challenge, but it also serves as an excellent
illustration of the intense spirit of collaboration among the
global scientific community to combat a global epidemic.
The SARS experience, she continued, reinforces
the need to strengthen global surveillance, to have prompt reporting,
and to have this reporting linked to adequate and sophisticated
diagnostic laboratory capacity. It underscores the need for strong
global public health systems, robust health service infrastructures,
and expertise that can be mobilized quickly across national boundaries
to mirror disease movements.
It is also important to note the role played by modern communication
systems, and in particular the Internet. Scientists in disparate
regions of the globe were able to communicate instantaneously,
sharing information and results. Heymann noted, Collaboration
is virtual. Members of the [scientific] network confer in daily
teleconferences coordinated by WHO, and use a secure web site
to post electron microscopic pictures of candidate viruses, sequences
of genetic material for virus identification and characterization,
descriptions of experiments, and results...The collaboration has
resulted in the identification of the suspected causative agent,
and the development of three diagnostic tests, with unprecedented
speed.
Steven Jones of the British Columbia Cancer Agency noted that
the Canadian research team that he headed posted their sequencing
of the genome on the Internet immediately after completing it.
People were, within minutes of that, able to download the
sequence and analyze it in their own laboratories and their own
computers. The Internet has had a profound impact on how this
data has been shared and how scientists have collaborated.
The latest information on the spread of the disease, as well
as diagnostic guidelines and public recommendations to contain
the spread of the virus, is constantly updated on web sites run
by the WHO and CDC.
The profit motive asserts itself
The spirit of international collaboration, even altruism, on
the part of scientists taking part in the SARS research is no
doubt real. However, science in capitalist society is not capable
of transcending the outmoded constraints placed on it by the profit
motive and national competition.
Indeed, from the very beginning of the disease, national interests
hindered progress. The Stalinist bureaucracy in China sought for
months to cover up the extent of the outbreak in order to prevent
it from hindering the integration of that country into the world
capitalist economy. There can be no doubt that the Chinese government
bears much responsibility for the extent of the diseases
spread in China and elsewhere.
Wherever the virus has gone, economies have suffered as people
stay home rather than spend and tourism falls sharply. The WHO
estimates that economic consequences could be as high as $30 billion,
with the brunt being felt in Asia. It is the threat to local businesses
and the national economy more than anything else that has determined
government action in the affected countries. In Canada, for example,
the government bitterly resented travel warnings issued by the
WHO with respect to Toronto. The primary fear was the effect on
the citys tourist industry, and government officials did
their best to downplay the significance of the threat even as
documented cases emerged of Canadians taking the disease to other
countries.
Moreover, even as the development of treatments is just beginning,
biotechnology companies, governments and some universities are
already rushing to patent everything from diagnostic tests to
the new coronavirus itself.
Universities in Canada and Hong Kong have filed separate patent
applications, as has the US CDC. The CDC has asserted that it
wants the patent only to ensure that the scientific material remains
open to all, but the growing struggle for ownership is reminiscent
of the sharp battle that emerged between France and the US over
credit for the discovery and sequencing of HIV. At stake are royalties
and profits made from the sale of vaccines and diagnostic tests.
Researchers at the University of Hong Kong were the first to
observe the virus in a microscope. According to Halison Yu, deputy
manager of Versitech Ltd., which handles the universitys
patent portfolio, this makes the university the early bird,
giving them rights to the virus. A university that is able to
secure such a patent is in prime position to attract investments
from biomedical companies seeking to profit from the disease.
According to Dr. Malik Peiris, a researcher at the university,
the patent was only filed after it became clear that other universities
were seeking to make a claim themselves.
The British Columbia Cancer Agency in Canada, whose scientists
were the first to decode the viruss genome, have filed a
patent application in the US for the commercial rights to the
genetic sequence. To their credit, some scientists have refused
to go along with the rush to patent. Marco Marra, head of the
Canadian team that did the sequencing, said he would not allow
his name to be placed on the patent application, thus forfeiting
any revenues the agency would receive. He told the Wall Street
Journal that he does not believe genes should be patented.
Several biotechnology companies have filed patent applications
for specific treatment methods. While most of these methods will
never be used successfully, the hope among these companies is,
as one executive put it, that they will win the lottery
by patenting the right treatment.
What will be the response of world governments to this crisis?
The lessons from SARS are clear: in order to combat the threat
of viral epidemics in a modern globalized society, it is necessary
to develop a globally integrated health system that includes extensive
funding of public health monitoring systems in underdeveloped
regions and throughout the world. It is necessary, moreover, to
end the underdeveloped character of these regions
and alleviate unsanitary conditions that can be a breeding ground
for new diseases as well as a fertile ground for the spread of
old ones. The modern advances in science and telecommunications
provide the necessary technological basis to combat the threat.
However, these requirements are in fundamental contradiction
to the tendencies of world capitalism, which are precisely to
break down all constraints on private accumulation, including
in particular public health systems. The US government, in particular,
chafes at subordinating its policies to an international effort,
seeing it as an unacceptable restraint on what the American ruling
elite views as its inalienable right to pursue its own interests.
Here the war in Iraqwhich has brought with it the complete
destruction of the basic infrastructure of Iraqi society, including
its health care systemsis instructive. The Iraqi people
are currently facing a growing cholera epidemic, a disease whose
spread is generally impossible so long as basic sanitation conditions
are present. At the same time as the United States is gutting
public health services within the country, it is devastating social
conditions around the world in pursuit of the interests of a small
section of the American population.
The devastating crisis presented by AIDS is also indicative
of the inability of capitalist society to deal with such problems.
Private companies that own patents on AIDS medications have collaborated
with the American government in preventing the production of generic
medication that could be made available to underdeveloped countries,
especially those in Africa, to help combat the catastrophe that
the disease represents there. The inability of AIDS patients throughout
the world to get necessary medications cheaply because of the
profit interests of a handful of pharmaceutical companies amounts
to a crime against humanity, resulting in the needless premature
death and suffering of millions.
Can there be any doubt that SARS, if it were to become a global
threat, would be treated in the same waythat public health
would be subordinated to private profit? The fundamental lesson
of the SARS outbreakillustrated both in the positive by
the international collaboration that went into the efforts to
contain the disease, and in the negative, by the rush to patent
its treatmentis that the health of the worlds population
in modern society is incompatible with a social system based upon
private profit.
