TYPE: Late Breaking Abstract
TOPIC: Practice Management and Administration
PURPOSE: Since the outbreak of coronavirus disease 2019 (COVID-19) in late December 2019, and the epidemiology situation in South of Far East of Russia is underestimated and needs to be monitored before and after vaccination. Aims was to estimate the incidence of COVID-19 among distinct territories of Primorye area (the South of Far East of Russia) and describe its epidemiological and clinical significance, to give microbiological analysis of respiratory tract pathogens isolated from COVID-19 patients. Total population is 4605 persons.
METHODS: We have alayzed data on epidemiology of COVID infection on regular statistics report from Hanka District Hospital (South of Far East of Russia) in the period from January 2020 till September 2021.
RESULTS: there were registered 1016 cases of COVID infection, in 74% cases it was accompanied by viral-bacterial associations. There were different stages of COVID , e.g. 48% were of mild forms, 11 % had severe course of disease. In age structure there were patients from 20 to 40 years (42%). In microbiology structure there were 42% of patients had bacterial-COVID viral association. In association there were prevailing of S.pneumoniae 18%, S.aureus 11%, A.baumannii 16%,C.albicans 7%, S.pyogenes 6%. There have been revealed that despite of vaccination 186 patients had the repeat COVID in 3 weeks after vaccination.
CONCLUSIONS: This preliminary analysis had highlighted the need for more robust and well-designed studies to better estimate COVID-19 incidence . Early identification of asymptomatic cases, as well as monitoring and tracing close contacts, could help in mitigating the spread of COVID-19.
CLINICAL IMPLICATIONS: Repeated COVID after vaccination.
DISCLOSURE: Nothing to declare.
