The Use of Machine Learning in Health Care: No Shortcuts on the Long Road to Evidence-based Precision Health
![a doctor points to different icons](https://blogs.cdc.gov/genomics/wp-content/uploads/sites/20/2021/12/2021_12_machine_learn.jpg)
Two recent systematic reviews reveal the high risk of bias present in randomized controlled trials (RCTs) and observational studies based on machine learning and artificial intelligence. Digitization of health data holds profound potential to change the way we collect information and interact with the health care system. In current times, an increasing volume of health-related Read More >

![a polygenic risk curve over a population](https://blogs.cdc.gov/genomics/wp-content/uploads/sites/20/2021/11/2021_11_polygenic_pop.jpg)
An international multidisciplinary group of experts in genetics, law, ethics, behavioral sciences, and other fields reviews the state of science on polygenic scores and highlights risks and gaps before widespread use in practice. Polygenic risk scores (PRS) combine the small effects of many genes across the human genome to estimate the risk of a disease Read More >

Malaria was endemic in the United States (US) when the Communicable Disease Center was purposefully opened in Atlanta, GA, rather than Washington DC, in 1946. The Communicable Disease Center, now the US Centers for Disease Control and Prevention (CDC), was started closest to where malaria elimination efforts were needed: the Southern US, including Georgia, suffered Read More >

![a person using scissors to cut DNA](https://blogs.cdc.gov/genomics/wp-content/uploads/sites/20/2021/11/2021-11_next_generation.jpg)
Over the last decade, genetic testing has evolved from examining a few well-defined variants in one or a few genes to the capability to examine much of the human genome using next generation sequencing (NGS). These analyses are particularly useful for disorders with locus and allelic heterogeneity, and are now the norm in several clinical Read More >

For a second year in a row, this Thanksgiving might not look the same as the ones before it, but some things haven’t changed. Even if you can’t see your loved ones in person, Thanksgiving is still a great time to talk to your family members about your family health history. Having one or more family members Read More >

Now, more than ever, we are aware that our environment has implications for our health. We are also learning more about the effects of inherited traits, such as blood type, on disease susceptibility and progression. Understanding the interactions between our environment and our genes and how they affect health outcomes offers a multitude of potential Read More >

For more than two decades, advances in genomics have promised a new era of personalized or precision medicine (i.e., the right intervention to the right person at the right time). Scientific evaluation of new gene discoveries has been aided by the launch of large-scale epidemiologic and clinical collaborative global studies. In a recent commentary, McCarthy Read More >
Posted on byThe Contributions of Host Genomics Research to the COVID-19 Response: It’s Not Just About Genes!
![COVID-19 and sequencing](https://blogs.cdc.gov/genomics/wp-content/uploads/sites/20/2021/08/2021_8_host_gen-1.jpg)
A recent large collaborative host genomics study provides valuable insight into the interplay of biology and epidemiology on COVID-19. The study was based on a meta-analysis of nearly 50,000 patients from 46 studies spanning 19 countries. The study found 13 loci (specific locations on various chromosomes) associated with COVID-19 susceptibility or severity through genome wide Read More >

The first reports of SARS-CoV-2, the highly infectious virus causing COVID-19, swept across the globe in December 2019, prompting a burst of scientific activity. The rate of research and discovery intensified as the pandemic grew, resulting in a flood of publications in journals and on preprint servers around the world. More recently, SARS-CoV-2 variants have Read More >

In the early days of the COVID-19 pandemic, when little was known about the natural history of the disease, predicting the course of the pandemic was of premier importance for treating sick patients and redoubling efforts to protect those at highest risk of adverse outcomes. To address this need, investigators used a study design that Read More >
