COVID-19 Timeline at NIH

Highlights Through April 30, 2020


This scanning electron microscope image shows SARS-CoV-2 (yellow)—the virus that causes COVID-19—isolated from a patient in the United States. The virus is emerging from the surface of cells (blue and pink) cultured in the lab. The image was captured and colorized at NIAID’s Rocky Mountain Laboratories in Hamilton, Montana.

The COVID-19 pandemic has certainly upended the way work is getting done at NIH these days. Thousands of NIHers are teleworking, and all labs have minimal staffing to carry on essential research or maintenance operations. But many NIH scientists have been working around the clock trying to decipher the secrets held by the virus that causes the disease and to develop treatments and vaccines. The NIH Catalyst has compiled a timeline highlighting much of what is going on during this historic time (see page 11).
