Hi doc, this regards to my family. My dad started coughing few days back which transferred to my mom and brother. I was not around during that time but even I am coughing. Then all got fever which was on and off as they felt cold as well. Since then they have been coughing a lot and their oxygen level is below 90% (mom is almost at 80%). We all are surviving on eating fruits and juices only as we have lost sense of smell and taste. I'm not sure if this might affect oxygen levels. Dad came out to be covid NEGATIVE. Rest of the family is still waiting to get the results. Fever is all gone but the oxygen levels are alarming. My family doesn't want to go to hospital but I am concerned. Please could you advise if we should go to hospital urgently considering we are coughing a lot and oxygen levels are low around 80%?
