Attention is invited to the fact that yellow fever is at present very prevalent in Guayaquil. Bills of health show 10 deaths a week from this disease, and taking into consideration that the mortality is about 25 per cent, and that a number of mild cases are probably not recognized, it is believed that 50 cases a week is a conservative estimate. This, in a relatively small nonimmune population, shows that the' city is badly infected. The disease has also appeared in Duran, across the river,- opposite to Guayaquil, and at a number of plantations along the line of the railroad between Duran and Bucay. This latter must also be regarded as infected territory. The number of cases of plague has increased in Callao and Lima, and Pacasmayo has suffered from a sharp epidemic during December and January. In this latter place the number of cases is now decreasing, but infection still exists and it is believed will remain. Plague is also epidemic in Catacoas, an inland town from Paita, and a number of cases is occurring in the Chicama Valley, of which Salavery is the port, and also at Trujillo. Chosica, on the line of the Central Railroad of Peru, about 25 miles from Lima, has also become infected, and reports 6 cases during the past two weeks. The prevalence of this infection is regarded as more pronounced in the 'Peruvian ports and towns than in the preceding year, and Guayaquil shows a greater number of cases of yellow fever than at any time since the epidemic following the great fire of 1903.' In fact, the danger to this port from these diseases has at. no time been greater than at present, and every precaution is being taken to prevent the introduction of infection.
