传染病 (chuán rǎn bìng): infectious disease

Influenza is a common infectious disease that spreads especially easily among people in winter and spring.

Doctors remind everyone that the simplest way to prevent infectious diseases is to wash hands frequently and ventilate rooms well.

Because this infectious disease spreads very quickly, the school decided to suspend classes temporarily and have students take online lessons at home.

With the widespread use of vaccines, many once-frightening infectious diseases have been effectively controlled.

Before traveling abroad, it's best to find out whether there are any infectious diseases spreading at your destination and to get vaccinated in advance.
