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." Warmer weather also means that people are going to be able to see one another outdoors more, and that can alleviate some of the loneliness people are feeling while also being safe. Again, make sure that you do not get together indoor with people, even your close friends. They may be letting down their guard, and there can be tragic consequences. I understand why people want to get together with their extended family and friends.
