ABSTRACT
We provide data on daily social contact intensity of clusters of people at different types of Points of Interest (POI) by zip code in Florida and California. This data is obtained by aggregating fine-scaled details of interactions of people at the spatial resolution of 10 m, which is then normalized as a social contact index. We also provide the distribution of cluster sizes and average time spent in a cluster by POI type. This data will help researchers perform fine-scaled, privacy-preserving analysis of human interaction patterns to understand the drivers of the COVID-19 epidemic spread and mitigation. Current mobility datasets either provide coarse-level metrics of social distancing, such as radius of gyration at the county or province level, or traffic at a finer scale, neither of which is a direct measure of contacts between people. We use anonymized, de-identified, and privacy-enhanced location-based services (LBS) data from opted-in cell phone apps, suitably reweighted to correct for geographic heterogeneities, and identify clusters of people at non-sensitive public areas to estimate fine-scaled contacts.

AIM: To estimate the prevalence of the genotypes of the candidate genes ACE (I/D, rs4646994), ADRB1 (Ser49Gly, A/G, rs1801252) ADRA2B (I/D), MTHFR (C677T, Ala222Val, rs1801133), and eNOS (4b/4a) and their association with hypertension in two ethnic groups of Mountain Shoria. SUBJECTS AND METHODS: A clinical and epidemiological study was conducted in a population compactly living in the hard-to-reach areas of Mountain Shoria (the settlements of Orton, Ust-Kabyrza, and Sheregesh of the Kemerovo Region). A continuous method was used to survey 1178 residents from the above settlements; the sample consisted of adults (aged 18 years and older), 565 people were genotyped. RESULTS: The prevalence of hypertension among the population of Mountain Shoria was 42.3%. The incidence of this disease among the Shorians was lower (39.9%) than that among the representatives of non-indigenous people (46.1%). The ethnically justified peculiarities of the association of ADRA2B and ACE I/D polymorphisms with hypertension were established. There were fewer patients with hypertension among ACE ID and ADRA2B DD genotype carriers in the cohort of the Shorians than in that of the non-indigenous population: 40.6% versus 58.6% and 38.3% versus 64%, respectively. Conversely, there were more hypertensive patients among the carriers of the homozygous ACE DD genotype in the native ethnic group (60%) than in the non-indigenous one (37.1%). CONCLUSION: Adverse prognostic ACE DD, ADRB1 AA, MTHFR TT, and eNOS 4a/4a genotypes were more frequently observed in the non-indigenous ethnic groups; the ADRA2B DD genotype was more common in the native population. Hypertension was associated with the ACE DD, ÐTHFR CT, and ADRB1 AA genotypes in the native ethnic group and with the ACE ID genotype in the non-indigenous population.
