If you are experiencing symptoms such as coughing, phlegm, and bronchitis-like symptoms without a fever, it is important to rest, stay hydrated, and monitor your symptoms closely. If your condition worsens or you develop a fever, it is recommended to seek medical advice and follow the appropriate steps for evaluation and potential testing. It is crucial to follow guidelines for hygiene, self-isolate if necessary, and not panic as severe complications from the virus are rare.
