At least eight strains of the coronavirus are making their way around the globe, creating a trail of death and disease that scientists are tracking by their genetic footprints.
While much is unknown, hidden in the virus’s unique microscopic fragments are clues to the origins of its original strain, how it behaves as it mutates and which strains are turning into conflagrations while others are dying out thanks to quarantine measures.
Huddled in once bustling and now almost empty labs, researchers who oversaw dozens of projects are instead focused on one goal: tracking the current strains of the SARS-CoV-2 virus that cause the illness COVID-19.
Labs around the world are turning their sequencing machines, most about the size of a desktop printer, to the task of rapidly sequencing the genomes of virus samples taken from people sick with COVID-19. The information is uploaded to a website called NextStrain.org that shows how the virus is migrating and splitting into similar but new subtypes.
While researchers caution they’re only seeing the tip of the iceberg, the tiny differences between the virus strains suggest shelter-in-place orders are working in some areas and that no one strain of the virus is more deadly than another. They also say it does not appear the strains will grow more lethal as they evolve.
“The virus mutates so slowly that the virus strains are fundamentally very similar to each other,” said Charles Chiu, a professor of medicine and infectious disease at the University of California, San Francisco School of Medicine.

Vaccination rates vary by county, determined by local factors
COVID-19 has disproportionately affected certain underserved and high-risk populations, including people of color, those with underlying health conditions, and those who are socioeconomically disadvantaged. Ensuring access to COVID-19 vaccines for these communities can help address the disparate health effects of the virus and achieve herd immunity.
The Biden administration has identified vaccine equity as a priority, but states and local jurisdictions vary in how and the extent to which they prioritize equity. Given that vaccine roll-out in the U.S. is inherently local, understanding how vaccination rates vary at the local level is important for informing outreach efforts and addressing equity.
Earlier CDC analysis found that, as of early March, counties with high social vulnerability had lower vaccination rates than counties with low social vulnerability.

Dr. Anandi Gopal Joshi, the first Indian physician trained in the United States
Anandibai travelled to New York from Kolkata (Calcutta) by ship, chaperoned by two female English missionary acquaintances of the Thorborns. In New York, Theodicia Carpenter received her in June 1883. Anandibai wrote to the Woman’s Medical College of Pennsylvania in Philadelphia, asking to be admitted to their medical program, which was the second women’s medical […]
