RESUMO
Respiratory diseases, with the proportion of acute upper respiratory tract infections being as high as 75.6-87.0%, were of the greatest military and epidemiological significance for the military staff in the Republic of Dagestan. There were high incidence rates of acute enteric infections, among which shigellosis caused by S. flexneri 2a constituted a high proportion. The epidemic process under dry hot climate was characterized by significant summer seasonal variations with its maximum incidence in August, which was associated with the water transmission route. Under mountain continental climate, the incidence of sporadic cases of diarrheas and gastroenteritis of probably infectious origin was prevalent without a significant seasonal upsurge.
