Although some experts think that there is still time to stop SARS (Severe Acute respiratory Syndrome) others argue that it is too late for even the most effective quarantines to halt its march. Even in developed courtiers like Canada, where government officials say SARS is not out of control, some health officials have said that SARS is probably unstoppable. Dr Gully, the senior director general of population health, Canada, said recently that SARS "probably is here to stay" and Canadians will "probably have to learn to live with it."
Dr Koplan, the former head of the centre for Disease Control and Prevention in Atlanta, USA, said recently that doctors will probably never be able to eliminate SARS, although they should be able to reduce the number of cases and deaths. "What we can hope for is a suppression and minimization,"
Dr. Koplan told reporters in Hong Kong, where he is advising officials and scientists at Hong Kong University. "To think that magically any government or any scientist in the world could stop this, like you stop a car at a stop sign, is very unrealistic," said Dr Koplan.
In many ways, the argument has some merit. Quarantines may not be 100 per cent effective and can sometimes drive people with the disease underground, increasing the risk of spread. Also, at the moment, there is no effective treatment for SARS and, as a respiratory ailment; it can be much more difficult to control than diseases spread through other routes, like blood.
But others, while acknowledging the difficulties and the many remaining unknown about this new disease, still hold out hope. Two top officials of the World health Organization (W.H.O.) refused to concede defeat and expressed hope that SARS could be contained if all countries maintain vigilance for the disease. "We don’t really have a choice" except to use all available resources to prevent the spread of the disease to more countries," said Dr Heymann, executive director of communicable diseases for the World Health Organization. "We have a chance, we believe, to stop this disease if we all work together," Dr Heymann said. Dr Mike Ryan, another W.H.O official said: We have to be realistic in our goals and aims. That’s all W.H.O. can do. History will tell if we are successful. »
