Covid-19 morbidity: Analysis of epidemiological, clinical and diagnostic aspects

ABSTRACT

Introduction: COVID-19, a disease caused by the virus named SARS-CoV-2, was declared pandemic by the WHO in March 2020. Until 9 June Cuba had reported 2 211 cases and 83 deaths. Forty-nine of these cases were from Santiago de Cuba, for a lethality of 6.12. Objective: Characterize COVID-19 morbidity in Santiago de Cuba based on the analysis of selected epidemiological, clinical and diagnostic aspects. Method: A descriptive cross-sectional study was conducted of the 49 patients confirmed in the province. A review was performed of databases, statistics, and clinical and epidemiological records. Estimation was made of incidence rates, arithmetic mean and median, percentage difference between the rates, and Fischer's exact test. Statistical association was determined with the software EPIDAT, using a confidence level of 95% and a significance level of ≤ 0.05. Results: The incidence rate was 4.7 per 1 000 inhabitants. The municipalities involved were Santiago, Contramaestre and Palma Soriano. The greatest risk lay in patients aged over 60 years, among whom coughing, fever and rhinitis were common symptoms. Of the patients studied, 26.53% were asymptomatic. The main associated comorbidities were hypertension and neurological and respiratory disorders. The results of the diagnostic procedures applied were positive RT-PCR, high LDH, C-reactive protein, hyperglycemia and diffuse inflammatory pulmonary infiltrate. A statistical association was found between the evolution period, 7 and more days from symptom onset to admission, and the degree of severity. Conclusions: The highest risk of becoming ill and dying was found in the most advanced ages of life. The most common symptoms behaved in a manner similar to the one described in the bibliography consulted, and so did the laboratory results obtained. Delay in reporting to health institutions and associated comorbidities were risks for progression to severity and death. © 2020, Editorial Ciencias Medicas. All rights reserved.
