Introduction: This acute viral disease transmitted by Aedes and Albopictus mosquitoes can manifest from
forms of mild to severe discomfort with high fevers and severe symptoms that affect the skeletal muscle
system with a prolonged duration of time after the acute attack. Objective: To describe the acute clinical and
epidemiological characteristics of patients suspected of Chikungunya, according to the Protocol of
Epidemiological Surveillance of the National Epidemiology Center. Subjects treated at the Health Center
District of Guazacapán from March to December 2015. Methodology: Retrospective, descriptive. It was
used the SIGSA 3 of CSG and Santa Rosa, Medical Records and Epidemiological Surveillance Protocol.
Descriptive study using proportions and 2x2 contingency table for obtaining sensitivity and specificity.
Results: 40% Dengue and 60%Chikungunya. 88% was diagnosed epidemiologically linked and 12% for
confirmatory tests for Chikungunya. Sensitivity and specificity of clinical conditions as Surveillance Protocol
for diagnosis of Chikungunya: 55.33% and 92% respectively. Common symptoms: fever 100%, cutaneous
manifestations 83%, arthralgia 74%, myalgia 67% and back pain 59%. Most frequent age range: 30-39 years.
Gender 1.1: 1 F: M. Frequently epidemiological weeks 13 and 18. Residencies predisposition: La Poza de
agua, El Astillero, San Pedro y Platanares. Conclusion: The case definition established by the
Epidemiological Surveillance Protocol of the National Epidemiological Center of Guatemala has low
sensitivity and adequate specificity for diagnosis of Chikungunya disease. Most Chikungunya diagnoses are
made by epidemiological nexus, the confirmatory tests are done only to know the surveillance. Fever is
present in all patients with Chikungunya. Chikungunya disease is more common in women in the third decade
of life and is present throughout the year, in various sectors and varies by small amount between
epidemiological weeks.
