This year the media has been focused on the Coronavirus and I have included a link to CDC reference. Remember healthy people have strong immune systems because they eat right, sleep and keep active. We surcumb to infections when we are tired and run down, then we have to get back to baseline. Take personal actions to take extra care of yourself, not worrying about this is one way to keep strong as well. I have loaded my purse and pockets with Sani wipes and I am trying not to hug or touch people since I surcumbed to the flu this year. I am over it but I think my immune system needs some healing time too.
