Mucus naturally helps in protecting the respiratory system by stopping dust and bacteria from settling into our lungs. However, excess mucus production leads to difficulty in breathing as well as throat and nasal discomfort.
Coronavirus (COVID-19) attacks the respiratory system, causing victims to experience coughing and shortness of breath as the infection travels down to the lungs. This, however, is not the case with all COVID-19 victims, but emergency help should be sought if one experiences trouble breathing.
