Boy this thread was well hidden… Been searching for it since it fell off the main page.
Hello Kitty: Hashem just wants more davening from you. Before a person is given a tzara, all the people who will possible be affected by it (that means even someone who is forwarded the name in a text) are taken into account. If a second person was diagnosed, just means to daven, daven, daven, and daven some more. Remember, Hashem doesn’t care the least bit about statistics. Or what doctors say.
