Perhaps the most important thing not to do is to not panic. Know the COVID-19 symptoms like it is the back of your hand and you should be able to sleep better at night. Peace of mind. Well, not quite, unfortunately because knowing the COVID-19 symptoms could also sow further confusion in the sense that there will be other viruses, illnesses and diseases, some mild, others serious, that exhibit similar symptoms.
Nevertheless. Confused you might be. But panic you must, probably do not need to. Knowing the COVID symptoms is, well, a case of so far so good. Because if you have come this far, you’ll know what to do next. You need to of course make sure that you haven’t actually got the virus in the first place. So this is what you do then. You contact the nearest qualified center and make the testing arrangements.
Should there be a busy waiting period for you, you’ll need to contact your employer (if you are not working from home) and let him know. There is nothing else he can do but exercise empathy on your behalf and of course show extra caution at the work place. He might want to alert your fellow-employees, but should not need to cause any alarm. Discreet, soft announcements should be enough to let everyone know that they might need to be on the lookout for symptoms.
But symptoms or not, there is nothing to stop you, to prevent you from going in to be tested. In the meantime, until such time that space can be found for you to be tested (it only takes a few minutes, and results are known within days), you would have to keep yourself under self-isolation at home.
