COVID-2019 PANDEMIC: EPIDEMIOLOGICAL ASPECTS
Introduction. The new COVID-19 pandemic has become a new challenge for all countries in the world, requiring adequate anti-epidemic protection of populations and territories with the purpose to reduce medical, economic, political and other losses due to the rapid spread of the SARS-Cov-2 pathogen. Systems of preparedness and response to biological threats are significantly different at national levels, which has essentially influence at possibility of timely assessment of unusual event and minimization of multiple losses.
The aim of the work was to compare epidemiologically important markers of pandemic course, to evaluate different pandemic’ response tactics in the dynamics of events on different WHO regions.
Methods. Analytical method of complex epidemiological method was used to evaluate of pandemic trends; dynamics and trends were determined according to WHO, euroCDC, CDC (Atlanta, USA), MoH of Ukraine and other online resources.
Results. The rapid spread of the novel coronavirus SARS-Cov-2 has been facilitated by globalization processes, and the delaying of WHO's declared the coronavirus outbreak a Global Public Health Emergency; non-compliance with restrictions on tourist and other migration processes of the population and goods from / to the affected regions. Early contracted the virus as a new pathogenic biological agent with a high epidemic potential has contributed to significant advances in the study of the epidemiological, clinical features of COVID-19, choices of treatment tactics and anti-epidemic measures.
Conclusion. The development of the COVID-19 pandemic was determined by the capacity of national biological threat response systems, the chosen tactics of anti-epidemic protection systems in accordance with the states capacity and the stage of emergency situations in the dynamics of the pandemic in temporal and spatial characteristics.
