Enteric Fever in Calcutta

present-day attitude towards the enteric fevers in India is reflected by Manson-Bahr in the 1940 edition of his invaluable book. He considers it to be the scourge of recently arrived young Europeans in India, ' but, fortunately, liability to infection decreases with length of residence, due apparently to a kind of acclimatization. The well-known immunity of native races to typhoid is probably due either to mild attacks of the disease in childhood or to the immunizing effect of living in constant contact with typhoid infection. The typhoid and paratyphoid infections among Europeans Jn the tropics appear to be more virulent, and to cause a death rate twice as heavy as that commonly observed in England. According to English statistics, the death rate is given as about 1:8 attacked, but in India only recently the death rate is stated as rather over 1:3'.
