Objective:

to evaluate the Nursing intervention on knowledge in dengue based on Swanson's theory.

Methods:

quantitative research of pre-experimental design with pre and post test, contextualized in the Family Physician and Nurse Office No. 5 of the Dr. Rudesindo Antonio García del Rijo Polyclinic of the municipality and province of Sancti Spíritus, in the period of November 2018 to November 2019. Study variables: level of knowledge of patients about dengue, age, sex, education. A structured interview with the patients was used to learn about the knowledge about the disease. After the intervention was applied, the population proportions were compared using the McNemar test.

Results:

the most representative group was between the ages of 45-54 years and male sex. The level of completed secondary schooling represents the largest number of individuals. Once the educational activities were completed, the patients included in the research achieved adequate results. The results obtained are encouraging, significantly raising the level of knowledge of the patients after the intervention.

Conclusions:

the nursing intervention was effective in increasing the level of knowledge about dengue in patients from a family doctor's office.
