Single Nucleotide Polymorphisms-SNPs

16.1K
A single nucleotide polymorphism or SNP is a single nucleotide variation at a specific genomic position in a large population. It is the most prevalent type of sequence variation found in the human genome. Point mutations that occur in more than 1% of the population qualify as SNPs. These are present once every 1000 nucleotides on an average in the human genome. Replacement of a purine with another purine (A/G) or a pyrimidine with another pyrimidine (C/T) is known as a transition. In contrast,...

Principles of Disease Surveillance

202
Disease surveillance is the systematic collection, analysis, and interpretation of health data essential to the planning, implementation, and evaluation of public health practice. This process integrates data dissemination to entities responsible for preventing and controlling disease, injury, and disability. Surveillance systems provide crucial information for action, helping public health authorities make informed decisions to manage and prevent outbreaks, ensure public safety, optimize...

Area of Science:

  • Epidemiology
  • Data Science
  • Geographic Information Systems (GIS)

Background:

  • The COVID-19 pandemic necessitates urgent research into its transmissibility, spread, risk factors, and economic effects.
  • Reliable data archiving and sharing are crucial for accelerating innovative research efforts against COVID-19.

Purpose of the Study:

  • To establish a collaborative and innovative archive of diverse COVID-19-related data resources.
  • To process and integrate heterogeneous datasets using GIS for comparability.
  • To make all open data permanently accessible via the Harvard Dataverse.

Main Methods:

  • Collected diverse data: daily cases, social media, mobility, health facilities, climate, socioeconomic data, research articles, policy, and news.
  • Utilized Geographic Information System (GIS) base maps for data processing and integration.
  • Published open data to Harvard Dataverse, assigning permanent Digital Object Identifiers (DOIs).

Main Results:

  • A comprehensive, integrated COVID-19 dataset was created and made publicly available.
  • Preliminary studies using the dataset demonstrated varying spatial transmission patterns across mainland China, Italy, and the United States.
  • The data archive facilitates comparative analysis of the pandemic's geographic spread.

Conclusions:

  • The established data archive is a valuable resource for COVID-19 research.
  • The integration of diverse datasets enhances the understanding of pandemic dynamics.
  • Comparative spatial analysis highlights regional differences in COVID-19 transmission.
