Coronavirus

To support efforts to control COVID-19, contact tracing must be implemented alongside prompt and extensive community case detection, and a high proportion of contacts must be reached. Our estimates imply that contact tracing could support partial relaxation of physical distancing measures but not a full return to levels of contact before lockdown.
AI Methods Make COVID-19 Forecasting More Local
S Fernandez, Nexgov, August 10, 2020
Artificial intelligence techniques have inspired a new COVID-19 forecasting model provide timely information at a more localized level. The researchers say that officials and anyone in the public can use in their decision-making processes. “We are all overwhelmed by the data, most of which is provided at national and state levels.”
We generated 649 SARS-CoV-2 genome sequences from infected patients in New Zealand representing 56% of all confirmed cases in this time period. The proportion of D614G variants in the virus spike protein increased over time due to an increase in their importation frequency, rather than selection within New Zealand. These data also helped to quantify the effectiveness of public health interventions.
We integrated baseline data on relevant community vulnerabilities with dynamic data on local infection rates and interventions into a Pandemic Vulnerability Index (PVI). The PVI presents a visual synthesis of county-level vulnerability indicators that can be compared in a regional, state, or nationwide context. We describe use of the PVI, supporting epidemiological modeling and machine-learning forecasts, and deployment of an interactive, web Dashboard.
