• Abstract:

  Malaria remains as the parasitic

  disease with the greatest impact worldwide.

  In Brazil, in the last years, almost all cases of

  disease have been recorded in the Amazon

  region. The fight against the vectors through

  insecticide treated nets is the main combat

  strategy. This study aimed to determine the

  protective effect of these devices on the malaria

  incidence in one municipality of Amazon.

  Was conducted with information the Brazilian

  Ministry of Health and with the analysis of

  10,050 slides of thick blood smears that were

  prepared and examined in loco. The Shapiro-

  Wilk test was used to determine the normality of

  the data and the Mann-Whitney test was used

  for all comparisons of the analyzed variables.

  The significance level was set at p ≤ 0.01.

  The results revealed a significant reduction

  in malaria cases in all analyzed variables,

  including the species of the involved parasite,

  the level and type of infection, and the gender

  and age of the diagnosed individual (p ˂ 0.01).

  These findings confirmed that these devices are

  an important tool for controlling the disease, as

  they represented a new variable inserted in the

  context of combating the disease in the studied

  population. Therefore, the use of insecticidetreated

  nets is recommended as a preventive

  measure to control malaria, and guidance to the

  population regarding the correct way to use this

  device is required to avoid problems such as the

  loss of naturally acquired immunity, reduction

  in the protective effect of the device and the

  development of resistance to the insecticide.
