Dehelminthization is a complex of measures aimed at treating helminthiases and protecting against contamination of the external environment by eggs and larvae of helminths.
Deworming should be planned, mass, first of all, to include contingents of people, among whom the given helminthiasis is most common. To conduct mass dehelminthization, effective nontoxic antihelminthic agents are needed that are convenient for use, for example piperazine , fenasal , dichlorosal, chloroxyl (hexachloroparaxylene). In order for deworming to be sufficiently effective, once the preparation is prescribed, it is necessary to neutralize feces containing helminths, their eggs or larvae. In the treatment of a number of helminthiases, the release of the infectious onset can occur within a few days (up to 10-15). In this regard, in rural areas where there is no sanitation, it is necessary to require patients to observe during this period a number of hygienic rules and especially the decontamination of faeces with chlorine lime . Medical workers carry out daily monitoring of compliance with preventive measures and the effectiveness of dehelminthization.
Complete extermination of causative agents of helminthiases in certain geographical or economic zones is called devastation.
