Pontiac fever has rarely been found in sporadic cases. Here, we report the first sporadic cases of non-pneumonic legionellosis, Pontiac fever in Japan. Case 1. A 53-year-old man with spinocerebellar degeneration was presented to our hospital. He had an acute onset of high fever and consciousness disturbance. A chest X-ray film on admission was normal, but transient bilateral pleural effusions were revealed on hospital day 14. Case 2. A 77-year-old woman with gastric ulcer was presented to our hospital. She had an acute onset of high fever. A chest X-ray film on admission was normal, but transient bilateral pleural effusions were revealed on hospital day 7. High fever, resistant to beta-lactam antibiotics, continued in both cases. Both had serologic confirmation of legionellosis by indirect fluorescent antibody assay for Legionella pneumophila without seroconversion for Mycoplasma pneumoniae, and Chlamydia pneumoniae, and had a good prognosis. Both were thought to be sporadic community-acquired cases rather than epidemics.

In spite of the very significant advances made during the 20 th century in the prevention and the treatment of communicable diseases, infections are still today, even in developed countries, a major cause of morbidity and mortality. New infectious diseases have emerged (AIDS, legionellosis, exterotoxigenic E. coli, Ebola fever), others have significantly reemerged (tuberculosis, diphtheria, Bartonella infections) or have seen their geographic distribution widen considerably (dengue, Hantavirus, West Nile Virus, Lyme disease). New and widespread hepatotropic viruses (mainly hepatitis C) have been identified, while the bacterial cause (Helicobacter pylori) of gastric ulcer was demonstrated. The second part of this review will deal with other examples of emerging or reemerging infections and with the problem of the increasing resistance of pathogens to antimicrobial agents. It will analyse the multiple causes of these various phenomena and describe the diverse strategies which should become available for the prevention and/or treatment of these numerous infectious diseases.
