Abstract :
: This study aimed to analyze the demographic and epidemiological features of
identified COVID-19 cases in Kazakhstan.
Study design: A cross-sectional study.
Methods: This cross-sectional study aimed to analyze COVID-19 cases (n=5116) collected from
March 13 to June 6, 2020, in Kazakhstan. The data were obtained from a state official medical
electronic database. The study investigated the geographic and demographic data of patients as
well as the association of COVID-19 cases with gender and age. The prevalence of symptoms, the
presence of comorbidities, complications, and COVID-19 mortality were determined for all patients.
Results: The mean ±SD age of the patients in this study was 34.8 ±17.6 years, and the majority
(55.7%) of COVID-19 cases were male and residents of cities (79.6%). In total, 80% of the cases
had the asymptomatic/mild form of the disease. Cough (20.8 %) and sore throat (17.1%) were the
most common symptoms among patients, and pneumonia was diagnosed in 1 out of 5 cases. Acute
respiratory distress syndrome (ARDS) was recorded in 1.2% of the patients. The fatality rate was
1% in the study population and lethality was 2.6 times higher in males compared to females. Each
additional year in age increased the probability of COVID-19 infection by 1.06 times. The presence
of cardiovascular, diabetes, respiratory, and kidney diseases affected the rate of mortality (P<0.05).
Conclusions: The results demonstrated a high proportion (40%) of the asymptomatic type of
coronavirus infection in the Kazakhstan population. The severity of COVID-19 symptoms and
lethality were directly related to the age of patients and the presence of comorbidities
