The Study of the Outbreak of Coronavirus Infection in a General Hospital in Almaty.

The study aimed to identify the possible causes of COVID-19 outbreak and its development in a general hospital in Almaty (from April 11 to May 6, 2020), where 682 persons were identified with a COVID-19. 546 were hospital employees (48.9%), including doctors (57.8%), nurses (53.4%), junior medical personnel (54.4%) and other personnel (23.3%), and also among 136 patients. The attack rate among women was 50.0%, and incidence rate was higher amongst young employees < 30 years old (57.0%). The analysis showed that there was a failure of the management of the medical personnel in such critical situation.

Analysis of COVID-19 pandemics in Kazakhstan.

BACKGROUND: 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). CONCLUSION: 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.
