[PEDICULOSIS: CURRENT ASPECTS OF THE OLD PROBLEM].

Analysis of data on the incidence of pediculosis worldwide has shown that this disease still remains one of the major health problems in many countries. The ways of transmitting lice and different (social and biological) factors influencing lice infestation are considered. The country's real morbidity rate, such as the ratio of the number of reported pediculosis cases to the amount of pediculicides sold at drugstores in both Russia as a whole and its individual federal districts in particular, has been investigated. The actual morbidity rate has been found to be higher than the officially recorded one.
