Covid-19 is a virus that the world is currently worrying about.

Symptoms that arise if infected with Covid-19 include fever, cough, flu, nasal congestion, shortness of breath, and sore throat.

Based on the symptoms caused, many people are worried if they have the characteristics mentioned earlier, for example, a cough.

To find out the signs of Covid-19 infection, it is marked by the color of the mucus that is secreted through the respiratory tract.

The color of the mucus that is released when infected with Covid-19 is not clear in color and tends to be yellow and even green and smells bad.

If the color that is released is darker, it is a sign that the viral infection in the body is getting worse.
