David Kind (the British science adviser to the government) and colleagues report
in Science magazine (8.9.2006) the outcome on a so called foresight study on infectious diseases.
Foresight studies use a bunch of scientific methods to make an educated guess about the future -- mostly covering the next 10 to 25 years. And regarding infectious diseases -- remember BSE, SARS and the like -- there's more to come, reckon the experts at least. Eight overlapping classes are numbered (1) new diseases eg. SARS, BSE and human influenza like H5N1, (2) infections with a developing resistance against standard treatments like tuberculosis and MRSA, (3) zoonoses, ie. infections coming from animals, including SARS, influenza, Lyme disease, (4) the big three tropical diseases HIV/Aids, tuberculosis, malaria, (5) epidemic plant diseases, (6) acute respiratory infections, (7) sexually transmitted infections, including but not limited to HIV, (8) animal diseases. Four important technology systems are considered for flexible detections.
