Everyone is in agreement there is light at the end of the tunnel, said Woolf. Again, make sure that you do not get together indoor with people, even your close friends. We have a combination of factors that allowed a very bad situation to get worse, said Dr Steven Woolf, a population health expert and a professor at Virginia Commonwealth University. Not having gatherings, indoors, with anyone we dont live with will also make a huge difference. She likened searching for the variants to "shining a flashlight in the dark," adding, "You're going to see something if you start to look, and we just haven't been looking."
Woolf called a possible global warming.
