肺炎 (fèi yán): pneumonia

Grandpa was hospitalized because of pneumonia, and the doctor said he needs a week of antibiotics.

He had a cough and fever for several days, and when he went to the hospital for a chest X-ray, it turned out to be pneumonia.

The baby caught pneumonia and was breathing very rapidly, so the mother stayed by the hospital bed all night without daring to close her eyes.

Elderly people with pneumonia often have atypical symptoms; they may not have a fever and just feel extremely tired and have no appetite.

The doctor reminded him that during pneumonia recovery, he should rest and not rush back to work, otherwise it could easily relapse.
