See below: Covid-19: https://www.cdc.gov/coronavirus/2019-ncov/index.html Please contact your doctor by phone for further evaluation and mechanism for testing in your area. Wear a mask, stay away from others, practice hand hygiene. If you develop breathing difficulty, go to the nearest hospital, immediately. Wish you good health.

URI: Absence of fever is reassuring. I believe you have a simple upper respiratory tract infection and are still in the viral stage. Rest up, drink adequate fluids and if the cough with discolored sputum doesn't improve but persists beyond a week, I would consider antibiotics for what would then be a bacterial bronchial infection. Perhaps your MD would be willing to prescribe and forego an office exami
