[The routes of the spread of cholera in the Shamil'skii Mountain District of Dagestan]. / Puti rasprostraneniia kholery v Shamil'skom gornom raione Dagestana.

The routes of the spread of cholera were analyzed in 273 patients and Vibrio carriers during the outbreak of cholera in a mountainous region of Daghestan during the period of July 18 to September 4, 1994. Cholera was found to spread mainly after funeral repasts and condolence visits accompanied by the dispensation of foodstuffs, transmission being realized through alimentary and contact routes. Under the conditions of the absence of the centralized water supply system in mountain villages and the contamination of water in open reservoirs it was found to be expedient to use, in addition to the recommended complex of antiepidemic measures, small automatic filtration units.

The data on the epidemiological analysis of cholera cases in the epicenter of this infection in the Daghestan, viz. in the village of Gerga, Kaiakent District, are presented. The outbreak of cholera was due to the import of this infection by pilgrims from their hajj to Saudi Arabia. The causative agent of the outbreak was the epidemic variant of V. cholerae eltor Ogawa. Everyday contacts were the main route of the transmission and spread of this infection, the water factor playing an insignificant role. Two epidemic waves of cholera were registered in Gerga, each of them provoked the penetration of the infection to other regions of the Republic of Daghestan.

1,713,057 cases of cholera were registered in the world during the seventh pandemic of the disease at the period of 1961-1989. The pandemic still continues, being the most prolonged pandemic in comparison with earlier ones. During the period of the seventh pandemic 10,723 cases of cholera were registered in the USSR. Great outbreaks occurred in 1965 and 1970-1974. At present sporadic cases of cholera can be registered, and wide circulation of mainly avirulent, nontoxigenic strains of cholera vibrios in environmental objects is characteristic of the epidemic situation.

[The practical performance of cholera control measures in the USSR during the 7th pandemic]. / Praktika provedeniia protivokholernykh meropriiatii v SSSR v period 7-i pandemii.

The critical analysis of anticholera measures carried out in the USSR since 1965 till the present time is presented. The grounds for the abolition or considerable reduction of a number of measures are considered from the viewpoint of their scientific substantiation, the adequacy of means and efforts spent for their realization and their antiepidemic effectiveness. Special attention is paid to the necessity of differentiated approach to these measures, depending on concrete local climatic and geographical, sanitary, hygienic and other factors which determine the epidemic potential of a given administrative territory.
