Electron microscopist Elizabeth Fischer has captured stunning images of the emerging viruses that cause Ebola, MERS, and now COVID-19.
Some of the more stunning images of the coronavirus—about 10,000 times smaller than the width of a human hair—have come from Fischer’s microscope. One is Fischer’s photograph of viral particles being released from a dying cell infected with the virus.
“This image gives us a window into how devastatingly effective SARS-CoV-2 appears to be at co-opting a host’s cellular machinery,” Collins wrote. “Just one infected cell is capable of releasing thousands of new virus particles that can, in turn, be transmitted to others.” In 2014, Fischer received a sample of Ebola from a 2-year-old girl in Mali. The cell border and nucleus shape resemble the shape of Africa.“This one particular cell, it looked like the continent of Africa,” Fischer recalls. “It was a very powerful moment. You see that virus growing in there, it takes you back around to not only the lab work we do, but that there’s an impact on human health.”
