Having worries, fears or moments where we are more cautious than usual is entirely normal, especially given the current COVID-19 situation.
In line with current MOH guidelines, if you feel you have a fever or any of the other symptoms for COVID-19, please see your doctor so that he or she can assess that there is a clinical need for you to do a PCR test. If it is deemed that there is a need for such a test, your doctor will be able to test you or refer you to a suitable swabbing site (e.g. Public Health Preparedness Clinic, Regional Screening Centre (RSC) or polyclinics) for the test.
It is also normal to remain worried about contracting COVID-19 or affecting others even after you've been given a clean bill of health.
If you have been taking the necessary COVID-19 safe distancing and precautionary measures but remain worried and feel that the worry has significantly affected or impaired your quality of life, you might need to speak to a psychologist or other mental care professional.
