Yes, it is possible to be infected with COVID-19 even if you only have a cough and difficulty breathing, without other flu-like symptoms. If you are experiencing symptoms such as fever, cough, shortness of breath, or extreme fatigue, it is recommended to consult a healthcare professional or use online tools provided by health authorities to assess your risk. If the tool advises you to see a doctor, it is important to go to a designated COVID-19 testing clinic rather than a regular clinic or hospital to prevent potentially infecting others. It is also advisable to avoid using public transportation when seeking medical help.
