BACKGROUND AND OBJECTIVES: A new wave of Covid-19 pandemic has worsened the epidemiological situation in Ukraine. This caused the need to tighten quarantine measures that have been introduced since 31.08.2020. The conducted analysis showed that there are 3 groups of technologies for digital contact tracing: from maximum (25%) to minimum (20%). Objective of the study is to develop an exchange platform to track the spread of COVID-19 in rural areas.
METHODS: Factor analysis identified key factors of COVID-19 virus spread. Cluster analysis identified clusters of COVID-19 spread. Taxonomy method established the limits of using contact tracing methods. Discriminatory method makes it possible to change the applied contact tracing method.
FINDINGS: The results showed that the identified factors (medico-demographic special features of Covid-19 virus spread; rural infrastructure to counteract the infection) describe in total 83.24% of the data processed. Specified 4 clusters differ in the level of susceptibility of the population to COVID-19 and infrastructure development: from minimum (33% of the united territorial communities) to maximum - 13% of the united territorial communities. The value of the integral indicator calculated provides means for establishing the maximum (8.5) and the minimum (2) limit of changes in the method of digital contact tracing.
CONCLUSION: The developed methodology was implemented on the basis of the united territorial communities of Sumy region. Monitoring of changes in the epidemiological situation made it possible to justify the need to change the contact tracing model, which will reduce the epidemiological level in the region as a whole by 30%.

- Two key factors of COVID-19 spread and resistance in rural areas were identified. The first factor (medico-demographic features of COVID-19 virus spread) reasons 51.25% of the processed data. The second factor (rural infrastructure aimed at combatting the infection) reasons 31.99% of the processed data;
- 4 clusters were identified, which differ in the level of infection and resistance of COVID-19 in rural areas of Sumy region;
- Different DCTT models are suggested to identify clusters according to the susceptibility level of population to COVID-19 and infrastructure development: from minimum (33% UTC of the first cluster) to maximum (centralized) - 13% UTC of the fourth cluster;
- The developed methodology makes it possible to diagnose the prevalence rates of COVID-19, to monitor changes in the epidemiological situation in the united territorial communities, to suggest appropriate models for tracking contacts, which will reduce the epidemiological level by 30% in general.
