AB Lice and Mosquitoes in Infectious Epidemics 
    The Académie de médecine has recently received two reports on epidemics. From experiments made in Greece, Georges Blanc and J. Camonipetros have definitely established the way in which dengue fever was transmitted in the Mediterranean epidemic. There have been 800,000 cases in Greece this year. Mosquitoes were suspected of being the agents of transmission, and experiments have conclusively implicated Stegomyia. Stegomyias that had bitten dengue patients were always found infected. It was proved that they transmitted the disease nine days after the bite and remained infective for at least twenty-eight days longer. Mosquitoes of the Culex group were found not to harbor or transmit the disease.The other report concerned investigations on a peculiar epidemic, observed in Marseilles, which has had some of the characteristics of typhus fever. It is more benign, however, and terminates spontaneously within a few days. Its microbial agent has
