Nowadays, the infectious disease breaks out now
and then. It causes so many problems for people that a lot of people
can't go to school or work. What's worse, some get seriously
ill or even die.
W hat should we do to avoid being infected by the disease? .
First of all, we should keep good habits, such as keeping
clean, eating healthy food, taking enough exercise and so on.
Besides, we should not go to crowded places. I ask but not
least, if we feel uncomfortable or have a fever, we must go to
hospital at once for limely treatment.
Happiness lies first of all in health. Only in this way can
we live a healthy and happy life.
