_Influenza in China._—We have been able to follow the pandemic quite consecutively as it has spread around the world, from a first outbreak in the United States in March, 1918. We repeat that the disease was presumably present in Europe and elsewhere previous to that time, as it was in America, but the particular virus which ultimately acquired sufficient virulence to produce the pandemic may well be that which came from North America. Did this virus arise from an endemic focus in this continent, or was it transported to us at a somewhat earlier date from Asia? McNalty states that influenza was present in China and in the Japanese Navy in March of 1918. He gives no reference. Carnwath makes the same statement and gives as reference the report of Kabeshima and Lee. The author has not been able to obtain this report. The Health Officer of Shanghai made the following report for May, 1918: “Towards the end of the month, reports were received of outbreaks of ‘fever’ which rapidly affected a large proportion of the employees of various offices, shops, police stations, etc. As a result of clinical and laboratory observations of cases admitted to the Chinese Isolation Hospital the disease was recognized as epidemic influenza. The same disease was reported to have appeared in Peking before reaching Shanghai, but subsequent reports showed that most of the river ports were almost simultaneously infected; that is to say the rate of spread conformed to the rate of conveyance by railways and boats of infected persons;” In November of 1918 an editorial note in the China Medical Journal reads as follows: “From nearly all parts of China reports are being sent to the newspapers of the occurrence of a severe epidemic of disease which seems to manifest itself in various forms. In Wusuch, where the disease is called ‘the five days’ plague’ the symptoms are said to be not unlike those of cholera, death in some cases ensuing in less than a day. In other cases it is complicated by severe and often fatal pneumonia. At Anking many cases have all the symptoms of typhoid fever, but the mortality is great and sudden. In one house four people died within a few hours of each other, and in another house eight persons out of eleven died. At Wuhu and other of the lower Yangtze ports it is said to resemble dengue fever and the mortality is so great that undertakers are finding it difficult to meet the demand for coffins. In Shansi, where the victims literally number thousands, the disease is regarded as influenza. In Peking fully fifty per cent. of the Chinese have been affected and the mortality has been heavy. Accurate reports from medical men in these cities would be very instructive.”
