For anyone who is a smoker, now might be a good time to give it up - at least for the time being. When you quit smoking, your lung function improves. Many of the deaths which have happened are probably due to pneumonia rather than the virus itself. As I understand it the pneumonia is caused by an opportunistic bacteria. I recently had influenza which developed into pneumonia. My doctor offered me an injection of 'flu vaccine. I told him I thought you needed the vaccine before you get the 'flu. He told me the vaccine attenuates the virus. I recovered in about two days. But with coronavirus, we don't have that vaccine. With coronavirus, if you smoke, you are probably much more at risk of dying.
