New York (Fides Service) - The exceptional discovery of the identification of the DNA structure of SARS Severe Acute Respiratory Syndrome virus does not guarantee, contrary to what has been said by the media, the immediate discovery of a vaccine or an effective anti-viral medicine. This is the opinion of Dr Kevin M. Cahill, a major American expert on tropical diseases. Director of the Centre for Tropical Diseases at Lenox Hill Hospital in New York which provides health care for people from all over the world particularly missionaries, Dr Cahill is also President and Director of the Centre for International Health and Cooperation of the city of New York. With this editorial he gives his testimony with regard to the real objectives to keep in mind in order to guarantee better health security for the citizens of the world who face the serious threat of SARS which continues to make victims.
