Hi I’m a little worried and not sure I need to be. My little boy who has just turned 4 was slightly coughing yesterday morning then seemed fine but since he woke today it’s chronic and sounds quite deep. He’s coughing and making a choke sound but he has no temp and no other symptoms. He’s not struggling to breathe and has no other medical problems ... do I just keep a eye on it? Is it the corona if he then also gets a temperature ? Do I need to call anyone? We have been inside for the last three days
